Villiziev colo is not closed. Villiziev colo does not close what does it mean Option of developing a cola of Willis at the sight of the blood flow

Little does it know that Villiziev colo is. A chain of sudin and arteries, which pierce the brain and most often the shape of a cola. Budova vilizieva cola can be seen in children, so you shouldn't talk about the norm in a different way.

Navigate as soon as the robot arteries are damaged, it may not take a trivial hour for healthy people. In terms of the essence, the art of acting is an additional role, so it is rare to lead to some serious pathologies.

Villosis colo rostashevuyutsya in the pavilion of the skull and is a hedge of anastomoses. At the end of the artery, there are number, stars and name. Villiziev can be closed as well as open. Neither one nor the other, it is impossible to name a pathology, but to cause serious illness or damage to the brain.

Vіllіzіev colo, the pathology of which it is necessary to finish it is very necessary, but only a few options in Budovi. All the stinks are vvazhayutsya the norm and do not require any additional detail. Neurologists or neurosurgeons are involved in the development of the system.

Classical Villiziev colo, vidpovidny norms, set up 5 arteries, which are developed in the brain of a bagatokutnik. As soon as one of the Sudins is on the clock, the system is open, it doesn’t mean that the people with the similar Budovian cola will get caught up in the be-like legacy.

Statistics talk about those that the classic closure of Villizyev is less likely to be deprived of 50% of people, but the number of people who fail is less likely to fail.

Vіllizіev kolo maє kіlka of important features:

1. There are 12 options for the Budov and the Villizia Cola. Most of them have a part of the art, but they don't know how to be a patient. We will broaden є option, in every day of the rear there is a complete artery.
2. Deyakі options budovi vіllіzіeva cola still vvazayutsya anomalies. For example, the visibility of 2 arteries at once, the split of the court, the trifurcation of the artery (split into 3 parts at once).
3. Unclassified options for budovi cola are tied from the front part, the stench is created more often. Ale to the children, do not produce acceleration, do not expect to be diagnosed. Z rear cola all navpaki.

Basically, the zavdannya of the stake is the prevention of bloodstending. Whenever there is a chance in the brain to go out of the way, the judgment of a vilizia cola is victorious as a spare. This allows the cells to not gin the brain when blocking the brain or blood in the tissue. This function is important not only with such severe camps, such as an insult, or with spasms of the brain, if the blood supply to the tissue goes down.

Possible pathologies and specialties

Mozok vvazhaєa one of the most common organs of the human body. Bagato fahіvtsіv upevnenі, wіth thе function іn individual, tο talk about anomalies іnіllіzіev cola іn thеіrе never mind. Transferring or predicting the traces in this vipad is important. In some cases, there are minor pathologies of the cola to be produced to a serious delay.

Tastes of nayr_znoman_tn_sh_: from the start of development to mіgrenia. It is important to diagnose pathology, so that the last hour of illness can be reached without making a clear diagnosis. One vidhilen є the classic Budova stake, ale the size of a small size. Qia asymmetry can lead to a headache.

best frequent pathologies Vіllіzіeva cola vvazayutsya:

• Hypoplasia of sudin. The pathology is associated with a change in the diameter of the sudin. Through small differences in the arteries of the roofs, there are more and in smaller numbers against them. When there is a breakdown in the brain, the pathology of the pathology may become uncommon for an hour. However, in case of deaths in the blood-postponed brain, the main function of the viliziev stake will be destroyed. Viyaviti hypoplasia even more easily for help.
• ... Tse can be tucked into the brain. Aneurysm є vipinenny and stonewalling of the wall of the court or artery. The patient does not see any discomfort until quiet fever, as long as the aneurysm does not break and does not cause bloodshed, he suffers from severe headaches and boredom. Tsei stan is not safe for life and for the secret medical assistance.
• Aplasia Sudin. The entirety of any part of a Villeziev stake. Qia anomalies develop in the womb. Visnichiti, it’s not safe, it’s important. The traces lie in the fact that the very part of the day is, where is the destruction, etc.
• Trіfurkatsіya arterії. Splitting the artery into 3 heads is more likely to be served up frequently. As a rule, the whole camp is not safe for the life of the people and not to create any negative inheritance.

Not all pathologies are found to be successful, in order to achieve the best results and follow the rules of prophylaxis, so that you do not get stuck in accelerated conditions.

Symptoms of pathology can be negative: headaches, tediousness, fear of bright light, decreased memory and respect, children may be able to start getting intellectual development.

diagnostic methods

For diagnostics of cerebral depression, start using non-invasive methods such as CT and MRI. In a large number of types of pathology, there is a type of complex treatment.

Before the patient grows up to a disease with already obvious symptoms, which are manifested in chronic headaches and memory damage.

Naybіlsh advanced methods of diagnostics of pathologies of vilіzіeva cola є:

Lіkuvannya in the main vimag tіlki aneurysm. The only pathology is possible only sposterigati. Aneurysm is treated with a surgical path. conservative methods do not give any result. It is not safe to dissect temporal aneurysms, or to carry out trepanation of the skull, seeing aneurysm and repair.

Є y іnsha operation, as it is not possible to undergo postal anesthesia, not to see aneurysms. Through a small puncture її zapovnyuyut special material, which does not allow їy rozіrvatisya.

For more information about aneurysms of the brain, see the video:

Hercules, as a rule, are tied with such a pathology, as aneurysm and growth:

1. Lethal result. Rise of aneurysms can lead to death of a sick person, the very reason in the development of a pathology is indicated surgical treatment, Poklikane zapobіgti similar result.
2. Gostra ischemia tissue to the brain. Through the disruption of the judge, one should be drawn back, or it is significant, the bloodstorming will be poured to the singing memory of the brain. The tissues are repaired to improve the functioning of the brain.
3. An abscess in the brain. Nabryak supervises pathological accumulations of birth in the tissues of the brain. It is not safe for such a stance that it is tied to the fact that the cranial bones are solid and hard, the stench does not get in the community, apparently, when the brain is filled with tissue, it can be repaired, which can lead to a lethal result.

It’s necessary to have a quick one, it’s necessary in the first place to change the way of life: more buvati on a new day, do not forget about physical options, I have vegetables and fruits. Tse spriy zmіtsnennyu all sertsevo court system as a whole.

Vіllizіev Kolo (VK) - tse system ob'єdnan sudin circulatory system in the brain (anastomoses).

It is given with half of the knowledge that it is the very basis of the organ. Circulus arteriosus translation from Latin means arterial colo - tse z'єdnannya honey by the system of sleepy vessels, as well as the arterial system of the vertebrobasilar basin.

Formation of systems of anastomoses in organs is important for non-standard situations in organisms. The body is suffering from a blood deficiency, which is sour, through a blood circulation system that is affected by a thrombus.

Lyudin is not aware of the function of this child of the court, therefore, the functionality of the court system has not been impaired. An option for the development of a cola of anastomoses in the organ, having been described more than 3 hundred years ago by the physician Villis.

Norms in the formulated stake of Willis

Check the value of the normative budget given to the body. Tse of anastomoses, which are selected in the ring and form a cola. Less than half of the people have such a budget given to the body. In people, the anastomoses of the Cola of Willis are formed with anomalies in the arteries of the small vessels.

Colo can be:

• close;
• Rozimknuty.

The anomaly of the arterial ring should not be caused to the enlargement of the ailments to the organ, I want the deficiency of blood supply of organs to periodically manifest itself in such discomforts:

• Migrene headache with villizia cola;
• Encephalopathy of an arterial character - to judge the body;
• Vіdhilennya in the blood-postured head in the state of the art, as the form is not infinitely accelerated - insult.

Options for Budovi and the formulation of types of Cola of Willis:

• Formation type - trіfurkatsіya;
• Type of budovi organ - aplasia;
• Hypoplasia type;
• Anomalies in Budov when there is an increase in the visibility of the judges and the elements.

Pathologies, which develop in vilizia cola, lie according to the type of treatment given to the body. Clinical manifestation and therapy of ailment can also be attributed to the bud's arterial type.

To continue the anatomy of VK vikoristovoyu:

• Non-invasive diagnostic procedures;
• Invasive diagnostics of previous revisions.

Budova stake of Willis

The classical formulation of the witch of the Villezivyi will establish the following arterial channels:

• Anterior artery to the brain (PMA);
• Z'єdnuvalne channel of the anterior viddilu (PSA);
• The bed of the back part to the organ (ZMA);
• Artery of the posterior organ (PCA) is obtained;
• Above the wedge-shaped view of the internal type of sleepy bed (ICA).

All the blood flow is set up with a seven-week figure of the base organ - the brain. The bed of the carotid vessels (ICA) delivers shelter to the organ from the posterior blood flow of the carotid basin and from the base to the organ to transmit the anterior viddyl (PMA).

The right-hand side of the anterior channel and the left-sided anterior artery ring behind the aid of the other vessels of the anterior organ (PSA).

The rear right internal sleepy artery shores the ear from the side of the backbone.

You can get the additional information about the internal sleepy artery by using it.

Understanding of both the BCA and the right of the BCA, as well as the WMA see the additional rear artery. ZSA will eliminate the bloodstending, either from the system of the basin of the sleepy vessels, or from the basilar basin.

functions

Vіllіzіy colo set up two flow of arterial blood flow from the basilar basin and blood supply of the head from the basin of the system of sleepy vessels. Provision of quiet parts to the organ, which does not receive additional food, is carried out for the development of the function of one of the primary channels.

The villosis of the swelling in the subarachnoid region is presented to the organ of the brain and the discharge of arterial elements (statements of the head), which create the chiasm of the healthy type and the inflow of the middle brain.

Behind the VK there is the organ of Varoliyev Mist, which clangs the ring from the BASILARY vessel.

The judges of the front end of the brain are formed good (in most cases) and the diameter of the lumen is up to 2.5 millimeters behind the standard stink indicators. PSA can be identical in diameter and before fat - up to 10.0 millimeters.

The diameter of the left-sided internal sleepy vessel is up to 1.0 mm per standard.

The vessel in the middle of the brain has an asymmetric shape - the left side is wider in diameter, and the right-handed side, which is less conducive to education.

A high degree of stability in the form is seen in the judgment of the front view - the price of sleep, as well as the brain. The judges of the rear view are more variable and may seem physiological and individual in the anatomical schemes of the day and age in the case of the disease.

In case of pathology of the channel of the anterior cerebral vesicle cleverly show better and better forecast for the development of this pathology.

role of VK

Viliziev colo is a central mechanism, which compensates for damage in the blood circulation system. Dana mozkova design is molded by nature, so that non-reversible inheritances can be eliminated by insignificant inconsistencies of living words in the brain.

As soon as one of the ships became defeated, so that the functional structure took care of the villas' circle and gave shelter to the heads of one of the ships, they were able to get it from the other pro-cezdat artery.

For the back of the vessel, the necessary blood supply is delivered to the body part.

The role in the blood flow system of the Willis's ring is even more important, and not only in the period of severe ailments, such as aneurysm of arteries, or even an insult, but to do so, if a convulsive spasm occurs.

With the occlusion of one channel, the Willis has a colossal function of pumping arterial blood.

Symptoms of occlusion and development of pathology, fluidity and area of ​​destruction, without the need to lie in the correct budget and some way effectively, it is possible to redirect the blood flow to the guardianship,

With a normal budget system, the Danes need to cope with the assignment to the new employees.

How close the circle is - it's good, why is it rotten?

When the VC is closed, the robot is returned to all vessels given to the body. The circulation of blood is considered for all the arterial systems. The transit of the flow of blood occurs mittvo in the place in which there is a deficiency.

Taking blood from two pools:

• Vertebrobasilar type of pool;
• Great stake for a pool of type of sleepy arteries.

Close the column - the normative indicator means that in case of detection of pathology in the body, blood circulation will be maximally accessible and compensated.

Close the VC - so good, so there is a guarantee that in times of striking one arteries, the brain will work in normal mode and the hypoxia will not develop, due to the inheritance, which is slowed down.

Villizyev is of an open type - a pathological anomaly, like a provocation in the blood-posture of cerebral speech.

The system supplies blood only to that part, to which it has access, but the organ does not visually function.

Types of abnormal visions when formulated:

• Aplasia of the posterior, as well as the anterior upper vessels;
• The rear judges were divided into three arteries (traffic);
• Aplasia of the basilar court in the case of the vilizia cola.

Physiological anomaly

The type of formulation of Willis' stake lies in the form of the intrauterine formulation of the maybutnoy people. Transmission, as it will be formed, given an additional system to the brain - it is unfortunate.

Nyposhirenіsha anomalies with vilіzіeva cola - the center of the trafurcation of the posterior ICA. More than 5 parts of all abnormal manifestations in the head evidence are brought to the traffic itself.

With this type of formulation of this pathology from the ICA, there are 3 arteries:

• Front plate of the brain;
• Middle cerebral vessel;
• Rear cerebral vessel (ZMA).

The back of the brain, є we continue to the back of the back of the brain.

Such budova is seen in the systems of the brain, typical for 16 - 17 intrauterine development the fetus, albeit when the baby is forgiven, is re-shaped by the priori judges.

The resulting vessels will change in size, and the main rear vessels will increase in their own diameter.

Stake of Willis anomaly - aplasia

Aplasia of the posterior cerebral arteries, also a widened anomaly in Budovia Cola of Willis.

An anomaly is given to the internal uterine ethology and is associated with genetic decongestant failures, as well as the infusion of specific factors in the period of intrauterine establishment of organs in the fetus.

In case of anomalous aplasia, on the other side, there is no rear ring of the artery, it is not the wickedness of the circle of Willis. With the opening of the posterior z'єdnannya - Willis of the open type and the basins - the basilar type and the pool blood flow of sleepy vessels.

The visibility of the blood flow along the insult to the posterior arteries does not allow the ability to function normally.

As far as the anterior cerebral artery is not involved, but the PMA segment, it is also diagnosed in the presence of a pre-diagnosis, albeit such an anomaly, but on the way.

With the given anomalies of mild mobility in the cola, redirect the blood flow from the left-sided vessels to the right-sided vessels of the given organ.

With an incomplete appearance of the artery, and with a hypoplasia, the blood flow along the a1 segment appears to be in a lower grip.

Given the aplasia does not give the ability to transport the necessary supply of living words on the other side of the arterial hedge.

In case of pathology in the appearance of the ARD, there is little flexibility from the offense of a part of the Willis stake - the front side, as well as the back edge.

There are no closures, no payment to the new department, no delivery from the spine artery in the ear of the box to the brain via the intracranial pa.

common anomalies

Before the malignant anomalies in the formulation of the Villizia cola, :

• Visibility of the artery of the middle corpus callosum;
• Free anterior cerebral vessel і right-handed anterior brain vessel placed in one artery, or else it’s roztashuvannya nastilya close one to one, but it stinks with its own stinks;
• Trifurcation of the carotid artery of the internal type of the anterior part to the organ - pathology is detected in the number, if from one internal vessel is divided by the entrance of the anterior two cerebral vessels in case of cola;
• The artery of the anterior part to the organ is obtained by the pathology of the duplication in case of a cola;
• There are two sides of the Willis' stake on the other side of the ship in the back of the stake;
• Bilateral traffic of sleepy types in the back of the stake in the case of a stake.

Atypical anomalies most often develop in the anterior part of the organ, albeit, as we already see, the most important pathology in the posterior part of the organ, because the stench is the most frequent provocateurs of serious damage to the brain, the result of the result

Pathology of the back cola is often diagnosed. Most of the patients who have developed pathologies in the brain of the child's severity, may cause anomalies in Budov's Cola of Willis.

Abnormalities in cola of Willis, do not drain blood in the brain with such pathologies:

• Hypertensive crisis s tricky adjustments index of arterial vise;
• With the spasm of the great arteries;
• With thrombosis;
• Pathology atherosclerosis;
• When developing stenosis of the arteries;
• Pathology of aneurysm.

pathology

The anatomy of the human organism is based on respect for the prosperity of all organs and systems, and it often suffers when the organisms are formed to develop and are undeformed, as a result of their functionality.

So it is seen from the organ of the cerebral blood circulation system - vilizia cola. More than 50.0% of the population may be experiencing anomalies in this stake.

The organ should be missed to the point of being overwhelmed sickly visions And also provoke a number of pathologies.

Open stake signs:

• Hypoplasia of the brain. Danish vice is the ringing of arteries. Hypoplasia protested in the body, not causing any severe symptoms, and most often diagnosed through the brain through the brain through their illness. Hypoplasia is good to start when the brain is undergoing the MRI technique (magnetic resonance tomography);
• Aneurysm of the small diameter vessel. The principle of the pathology is to pay attention to the part of the vessel for the newest wall, the sign of the development of ill health, and the extension of pathology in the main view is asymptomatic. Symptoms are manifested in the period when the wall of the urazhenoi judge is growing. Signs of aneurysms are: strong beat in the head, nudota, as provoking strong blues, the reaction of the healthy nerve on yaskrav svitlo. In case of aneurysm attacks, it is necessary to immediately visit the brigade of high-quality assistance and to see if the life of a sick person can be lost. Aneurysm develops rapidly and people fall into a coma with an offensive fatal result;
• The Danish camp must be made to the point where the quality of the stake of Willis is diminished (as if it’s an unstoppable vessel є, but it’s not the same for the newcomer). Tse means that the compactness of this circle is not essential. Most of the sailing boats are in the rear window. The diagnosis is made by the method of magnetic resonance imaging (MRI).

Tastes from the VK anomaly

The pathology of vilizia cola, which may be natural, or genetic, cause the entire blood flow system to break down in the middle of the brain. Signs of this vision may appear even from an early child's life.

In the abnormal amount of blood pressure, because of the lack of closure in this organ, and because of the lack of visibility of its functional capacity, the difference in arterial pressure in the lower cerebral vessels does not appear.

Dane vidhilennya to bring to such inheritance:

• Often the head is circling, yak inodi buvak is strong;
• Zapamorochennya to produce to a lot of tediousness, yak pass into blues;
• Zapamorochennya when changing the position of the head, especially with a sharp turn;
• A strong beat in the head, as you do not know about noxious drugs;
• Migren attack, when there are nudotas, blues, an inappropriate reaction to yaskrav, light and dull sounds.

best unfailing legacies abnormal organ system and cerebral circulation of Willis Cola, є:

• Aneurysm of arteries with a great diameter;
• Ischemic stroke.

In case of aneurysm, there is a rapid growth of the damaged artery, which can lead to death during the deadly hour.

In case of an abnormal growth of Willis' stake, the area of ​​injury is significantly increased in case of stroke, and a fatal result is also observed in case of an unfortunate additional dose.

Signs of anomalous Budovi

Klinic signs of an underappreciated VK will only appear if it appears in the body serious pathology in the bloodstream system, yaka led to a lack of adequate blood in the cells of the brain:

• Atherosclerotic plaques were established on the arteries;
• Thrombosis of arteries of a sizeable diameter;
• Getting into the artery of the embolus, such as blood transporting from the left-sided shlunochka, or the left-sided atrium;
• Coronary insufficiency, yak to produce damaged blood flow;
• lack of legendary artery Also, the blood circulation is damaged, and the brain is inadequate; a number of living elements is needed;
• Aneurysm of the cerebral arteries.

Symptoms of impaired blood flow with anomalies of the Willis Cola

Symptoms of impaired blood circulation appear to be the cause of pathology in the bloodstream system, as well as in the organs of the brain. With a rosy stroke, symptoms are characteristic of this pathology, with encephalopathy, there will be symptoms.

Symptomatology in case of damaged blood circulation in the brain is considered:

• Stronger head dizziness;
• Strong beat in the head, as it will do when you change the position of the head;
• Inadequacy of correct mislity is difficult in intellect;
• Reduced concentration on subjects and situations;
• Rise of a decrease in memory;
• disrespect;
• Prishvidshene sercebittya;
• zadishka;
• Panika's attack;
• fear of fear:
• gratitude;
• drowsiness;
• Organism stomluvance;
• Vidhilennya in the healthy body - unclearness and size of objects;
• Distinguish the intramural apple of the duplication of objects;
• Noise in vuhah, as if it could be heard during the reaction of the auditory nerve to moving sounds;
• As soon as possible.

diagnostics

Most people are suspicious of anomalies of Willis' stake, and they see this result only in case of previous cerebrovascular accidents.

If the symptoms of the development of aneurysms of the arteries are manifested, then an onset diagnostics is carried out for the development of the cerebral arteries:

• Non-invasive method of monitoring the organ- computer tomography - angiography (CT). This is a method of roentgenologic nature, when a special contrast agent is injected into the bloodstream of the brain, for the detection of diseases of all cerebral vessels in case of anomalies of Willis cola;
• Non-invasive MRI technique (magnetic resonance imaging) in case of anomaly of the Willis's ring- the most common universal method integrated dosageі to reject the image of the entire court system in detail;
• Invasive reversal of the organ - angiography. The technique is given It is based on catheterization of the artery system of the head, when a contrast warehouse is introduced into the artery system. І carried out X-ray of the vascular system.

Medication for treatment of anomalies

Yak likuvati? At the development of anomalies in the villizia cola, drug treatment is aimed at preventing the acceleration of pathologies, as it can reduce the function of a given organ:

• For the improvement of blood circulation in the head with pathology of Willis cola - nootropic activity (the drug Piracetam, as well as Nootropil);
• A group of sudinorosilicidal preparations - medication Cinnarizin, Vestibo;
• A group of antispasmodic medications - papaverine;
• Medicines, which can be used to color the recovery of acidity with anomalies of Willis cola - Cerebrolizin, the drug Solcoseryl;
• The group of sedative lykarsky zasobiv - Valeriana;
• Statini for Willis cola anomalies - Atomax.

Villosis is the system of cerebral blood flow, functions, and what kind of reserve, in case of such pathologies as aneurysm, thrombus arteries, stagnation of the surgical method of pathology elimination.

prophylaxis

Prevention of this organ is based on the possibility of all possible pathologies and blood flow to the organisms in case of anomalies of Willis cola, and come in on the offensive:

• Continuous control of the coagulation system;
• Control of blood index of cholesterol in case of VC abnormality;
• Normalizuvati index AT;
• Correct grasping with anomalies of the Willis' child;
• Treatment of all pathologies of the heart organ and the vascular system;
• Chance to vilikuvati vegetative-sudinu dystonia with anomalies of Willis cola;
• Take care of the charts of the system and the Sudin for a child's wick;
• unicati stressful situations You can provoke spasms.

Forecast for life in case of anomaly

To carry out promptly diagnostics for the detection of pathologies of the head and in case of an anomaly of the Willis 'circle, take care of the prophylaxis of the system of willis - that is, the prognosis of the Willis' cola is friendly.

When the possibility of a quick weakening is lost, the systemic blood flow in the head and with an accelerated form of pathology of aneurysm, as well as an insult, is a prognosis for the life of the Willis' stake of unwillingness.

You can get sick because of the pathology of the disease.

Vіllіzіev colo (faster VC) - the whole system of anastomoses (z'єdnan mіzh vodinam) blood-bearing vasculature, spaced in the subdivision of the brain. Winning protection is more important for the systems of internal sleep arteries and the VERTEBROBASILAR pool.

Before the warehouse of VK, there should be a number of arteries, yak, z'ednuchis among themselves, set up a colo. In most cases, there are a number of closed circuits, but for some people, we can see one of the Sudins, through which we are old. They call it options. Deyakі z tsikh options in development can lead to an increase in risik ill-gotten sick the brain, such as an aneurysm or a stroke.

Protect the majority of people have different options for VK physiological norm, so that the stench does not affect any symptoms but rather inherited ones.

So, as the acceleration of the wrong development of the viliziev cola appears in the brain, neurosurgeons and neurologists are engaged in them.

Budova Villizieva Cola

The brain is not an excess of the organ in the human body. It is not marvelous for him that this bloodstending is one of the most important goals. heart-vascular system... Mozok will take shelter from two dzherel - from the system of internal sleepy artery and from the vertebrobasilar pool.

In order to unify catastrophic inheritances when one of the great vessels is overrun, between two blood circulation systems, anastomoses can be formed, so that the base of the brain of Villizia colo is formed.

VK is stored in three pairs of main arteries:

1. The anterior cerebral arteries (PMA) are seen from the internal sleepy arteries.
2. Internal sleep arteries (ICA) - before the VK warehouse, the thermal part is included, before the middle cerebral arteries (MCA).
3. The posterior cerebral arteries (ZMA) are the endocrine arteries of the basilar arteries (BA), as they become part of the evil spine arteries (PA).

For the completion of the stake, two other blood-bearing judges are also present:

1. The anterior spinal artery (PSA) is one between two PMA.
2. Rear arteries (ZSA) - heads of the Arteries of the Armed Forces, which lead to the ZMA.

Yakshho Villiziyev has a number of closed circuits, the shelter can, if necessary, pass through the anastomosis from one artery to the insha.

Options for VK development

Turn on the VC, in which there are no outside or underdeveloped (hypoplastic) warehouses, only 20-25% of people are developing.

There is a majestic number of available options Anatomical Budoviі development of VK. The most widespread from them:

• hypoplasia of one or two ZSA;
• hypoplasia or the visibility of the PMA segment;
• PSA hypoplasia;
• the visibility of one of the ZSA.

B - hypocrisy of the right rear artery

C - hypocrisy of the left rear artery

D - bilateral hypoplasia of the posterior cranial arteries

E - absent, for the right of the posterior cerebral artery is not open

F - vіdsutnya because the liva posterior artery is not open

G - hypoplasia of the left full artery and during the day, for the right of the posterior cerebral artery is not open

H - hypoplasia of the right artery and all day long if the back of the brain artery is not developed

I - hypoplasia of the anterior cranial artery

J - anterior cranial artery and hypochondrium

K - hypoplasia of the right anterior cerebral artery and hypoplasia of the right posterior cerebral artery

In practice, it means the development of VK

Asymmetry of budovi VK is to produce blood flow asymmetry and an important factor in the development of internal cranial aneurysms and ischemic strokes. The price of destruction is known to be found in young patients, in some VK roznutsy between buildings until compensation gostrych changes in the arterial blood-postulated brain.

Before the development of the chicks, they are ill, or they do not know about those who have anomalies in the development of the brain.

Sudin VK aneurysm

Aneurysm is the key to the vascular endowment. Sudin aneurysms, which enter the VC, are the most common cerebral aneurysms. The most frequent odors are found in the PSA, at the bifurcation (duplication) of the BCA and in the ZSA, at the bifurcation of the BA.

The majority of cerebral aneurysms do not show any symptoms to their full extent. However, at great sizes vipinnya can winicatizhennya razmіshennyh handrail fabrics central nervous system, For doyak people to bring up to:

• double in the eyes;
• expansion of the site;
• vinnennyu pain behind the apples;
• headache.

With the development of aneurysms, Sudin, which is included in the VC, develops hemorrhage in the space near the brain (subarachnoid hemorrhage), until symptoms of which lie:

1. Raptova with an important headache.
2. Nudota and blues.
3. Skoost in shia.
4. Timchasova vrata zoru abo svіdomosti.

Ischemic stroke in case of small variants of Budov and VK

Disruption of the symmetry of blood flow through the arteries of the brain can lead to the development of atherosclerotic lesions, which leads to an increase in the development of ischemic insult. VK opening will not provide good collateral blood flow;

Symptoms of an ischemic stroke:

• Raptovaya belts are similar or weakness in the meat of one half of the body.
• Rapt destruction of evidence, destruction of evidence.
• Raptovo destructed to the zoru.
• Rapid failure of walking, loss of damage, loss of almost equal movement and coordination of movement.
• Raptova with a headache.

Diagnostics: identification of options in Budov and Villizia Cola

In most people, VK non-closure does not manifest itself. The development of a cola cola and this option is most often vivid, when the brain is judged for some reason.

If the patient has symptoms of non-invasive cerebral aneurysms, the following should be done:

• CT-angiography - non-invasive (without penetration into the body) X-ray examination, before the hour for visualization of the brain into the bloodstream, a contrasting speech line is introduced, and then it is displayed computer tomography.
• Magnetic resonance imaging is a non-invasive method, such as a vicious magnetic field and radio frequency impairment for removing a detailed image of the brain.
• Angiography of the brain is an invasive condition, when a special catheter is inserted in the artery of the brain. Contrast is injected through the catheter and X-ray sign.

Lіkuvannya options for the development of a vіllіzіeva cola

According to its own options, the development of VK does not є become ill and does not require treatment. Also, the presence of aneurysms called for the development of aneurysms or an ischemic insult, to carry out the treatment of ailments.

The brain system can be folded into the brain. One of the most important warehouses є Villiziyev colo. Wine is a complex of arteries, which are rosted to the base of the brain.

The staff of you will see the correct flow of blood in the event of a deterioration in the function of sleepy arteries. To that, be it pathology in its development, it can provoke the appearance of negative inheritances. In order for them to come out in good time, you need the nobility of Budov and the specialty of the Villiziev stake.

What is the warehouse for?

It is necessary to go to the first place, but also - Villiziev colo. Tse anastomosis of the arteries to the brain, which has the shape of an oval vint. The name of the tse was adopted after the honor of the first person - Thomas Villis.

Kolo pretend to be such arteries, yak:

1. The back is available.
2. Posterior mozkov.
3. Front mozkov.
4. Internal sleep.

Such a Budova stake allows you to draw between two systems: backbone-main and sleep.

The development of a cola cola is often found for the classic version. In most cases, it will be symmetrical to the vertical axis. Pathology of budovi is often observed.

For the functions of the report

The main staff of the system is to provide sufficient blood supply to the brain. It is especially important in the destruction of blood flow in the arteries of the shia. The complication of the flow of blood through the shinny arteries will clog up the sore starvation of the brain, which provokes the development of the disease. For this purpose it is not necessary to transfer, and transfer of Villizia colo.

The safety of the stake's functionality is within reach of the fact that the sleep of the artery is tied not only with oneself, but with the spinal artery system. Such a scheme allows you to continually pump the brain with lively talk.

According to the statistical data, the classic version of the development of the cola cola is reduced to 50% less. In bagatokh people, this symmetry is ruined.

possible pathology

The anatomy of a human being is transferring to a foldable budget of internal systems, as it will secure the povnotsinne function of an organism. It's a pity, often due to good reasons, people are encouraged to start developing. Tse buvaє і in times of vilіzіeva cola. Yogo is more normal than half of the people.

Most often, the development of the classic version of the development is manifested in the asymmetry in the flow of the bottle or in the daytime of the cola bottles. Often the visibility is observed in the diameters of the spinal arteries in the back and front parts. The results show that the collapse of the symmetry of the cola becomes the cause of frequent migraine attacks.

Among the most significant pathologies:

1. Hypoplasia. It is a defect of development, in case of artery, there is a strong change in parameters. As soon as in the other basins of the brain there is a loss of blood flow, the hypoplasia will be asymptomatic. Such pathology can be found in the course of complex diagnostics of the brain. Goodness is seen on the signs that are removed during magnetic resonance tomography.
2. Aneurysm. The price of the artwork is named. The disease is asymptomatic until quietly, as long as aneurysms do not develop. Tse to produce blood in the brain. At the same time, there are unbearable headaches, an attack of boring and blues, and a state of reaction on a yaskrave light. If you don’t live for a moment, then you can fall into a coma and die.
3. Aplasia. Tse stan, when there are Villiziyev, there are no closures at all times of the whole artery. You can also try to sprint the yak in the front view, as well as in the rear. If the artery is all the same, the presence is ale, it is even more rotten, then the diagnosis is not correct. Pathology in the anterior part of the cola grows in the edge rather rarely, depriving in 4% of cases. Most of the time you come back. Risimknutiy kolo look for an additional MRI. The reason for such a manifestation is the development of the fetus at the stage of the formation of the fetus.
4. Trіfurkatsіya sleepy artery. Tse splitting of the artery into three warehouses. The same results are observed in 28% of respondents. It’s not safe to imagine, as long as they don’t support occlusive vintages in the arteries. Develop front and rear traffic. The same vidhilennya is tied with a close reduction of the resulting arteries in the period of the embryonic development.

Before pathologies, which develop in the region, it is rare to recognize Heibner's artery, splitting of the anterior artery, gossip is a common type of basilar arteries and actions of the inshes.

What are some of the inheritances that can cause the wrong development of the Villa Cola?

The normal camp of Villizyev has a number of closures. Win vistupa in the role of a backup system. If there are some failures in the robotic arteries, you cannot be spared, then you won’t get involved. To that, if in a new presence, the appearance of a normal development is evident, the stench does not appear.

When problems arise with the supply of lively speeches, Viliziev colo will turn on to the brain. Winning additional help to pump shelter from other children. In general, there can be negative traits for health.

The incidence of pathology of the cola in the singing situations to produce before the obstruction of cerebral blood circulation. Vono can be manifested in the same early vіtsі and with an hour of growth.

On the basis of the arteries of the brain, in the cola bottles there is no tendency to grow back. The price is tied from the outside of the time by the grip of the brain tissue. Tse can produce up to the onset of negative inheritances:

1. Often zamorochennya.
2. Inconsistency in head position change.
3. Severe headaches, as you do not expect to be given a dose of antibiotic drugs.
4. Attack the migraines, which are supervised by fear of fear, boring, reacting to sounds.

One of the most unsafe pathologies is aneurysm. You will be here in the history of the stonewalling and adjusting the elasticity of the artwork. Moreover, the process is completely asymptomatic. Be-like an infusion on the head area to produce aneurysms until the instant. It’s impossible to live for a while, people just go down.

How can I see you?

Most of the pathology development of the viliziev cola appears in case of a complex patient's condition, which turns into a headache with scars. In the first place, in such a situation, it is necessary to reconsider the impairment of blood circulation in the brain.

MRI is the most accurate and precise diagnostic method. Debriefing is carried out on a special magnetic resonance tomography. This principle is based on the fixation of reactions of the client in response to the injection by a strong magnetic field.

So the round-up of additional help otrimaty on the other hand about Budova be-yak internal organs, Including the court system. MRI is used to increase safety, as it is non-invasive and does not transmit radioactive optimization.

angiography

Angiography is one of the most popular methods for securing the court system. Qia method of transferring a special contrast of speech into the patient's shelter. In order to do so, it is easy to agree on all arteries, to be afraid of the X-ray sign. All pathologies are clearly visible on the new one.

This can be done behind the aid of an extraordinary X-ray or computer tomography control. The contrast of speech is not surprising for people. In the singing hour, I will start to vivodit to the body by the natural path.

For viznachennya exact rostashuvannya and start arteries zasosovat also a computer tomography. The same is done because of the X-ray optimization. If the dose of investment in the region is small, the whole diagnostic method cannot be called safe for health.

yak love

Since in the course of the course, there is a safety for the life of pathology, for example, traffic, then any special addiction is not needed in any way. Ale varto pam'yatati, well, the health of the country can quickly deteriorate when there is an acceleration, for example, thrombosis of sudin. Recommended for this patient to come in, direct for preventive maintenance.

need to get ready correct eating, Viklyuchiti vzhivannya overmіrno fatty їzhі, greased, smoked herbs. Viewed from shkіdlivyh ringtone... Namagatisya yakomog more fresh vegetables and fruits. Lead an active way of life, more walks on a fresh meal. Everything is friendly to the health of the heart-vascular system as a whole.

operation

If aneurysm is diagnosed, if the term is required promptly involved... It is impossible to tackle such a problem by any means. The operation is carried out under anesthesia.

Hirurg to rob the opening of trepanation in the patient's skull. Writing a lot of wines rossovu fabrics, schob reaching the school artery. For the help of special tools, the doctor saw aneurysm and bandaging a vessel.

Then it’s possible to get lost only to introduce the cerebral sheath and attach the seam. Most often, for such an operation, it is necessary to take medications for treatment, as they are straightforward to get the most out of them.

It is a simple option of the operation, if an aneurysm is not seen, then it is not possible to see the rupture of the blisters. This procedure is carried out with muscle anesthesia. Hirurg to rob a small puncture in a dish and to enter into a new special tool. On the other hand, the memory of the empty aneurysms with the singular material in the eyes of microscopic spirals will be stored.

Spiral thrombus to the fact that in empty aneurysms there is a thrombus. In such a rank, pathology will increase in the process of blood circulation.

Before the hour of the operation, the surgeon needs a little more respectfully, so that the least inaccuracy leads to the development of aneurysms and hemorrhage. In three months after such a test, a control check is carried out on a regular basis.

Vіllіzіev colo - tse a reserve system of blood supply to the brain. With the development of pathology, it is necessary to regularly pass the condition of the development of aneurysms.

I'm going! I have 57 rockies. Often the head hurts, there is a problem with numbness. MRI showed a variant of the development of viliziev cola in the viglyadi of the daily blood flow along the back of the posterior arteries. Why is such a pathology not safe, what are the symptoms, how do they appear?

Valentina, me 33, and I also have a foolish woman + a bouquet)))). Funny)))))

I have 32 rock. The MRI showed that my Sudin system of the Willis Cola was damaged by 55%. Chi is not safe?

Kolo villizieva and Zakharchenko - what are the functions? First function - tse anastomosis, and a friend of a yak? Termynovo is required!

Try to put p'avok. The result is fantastic!

Fewer of the headaches had pains and boules, when they were trained spirally with hirudotherapy, everything went well. I would like to go to the ryk demand for likuvatisya. And what about the chemistry of kovtati? І so їmo one chemistry with the store.

I had a variant on the MRI of the development of the viliziev cola in the viglyadi of the blood flow along the backside of the back arteries and the anterior side-to-side traffic. Some of them had an MRI scan of the brain, and a car, having suspected an aneurysm through uncharacteristic repetitions, having projected the growth of MRI arteries. I didn’t suffer from a particular headache, the defect appeared vipadkovo. Likar said, “Villiziyev’s colo is a reserve system of blood circulation, as it’s going to start in times of trouble.” Go, I have no reserve.

In 19 rockies, terrible headaches had been born, until they lost their testimony. They injected injections, drank the pills, they didn’t get rid of it. Having consumed the device Magnitoturbotron (physiotherapy), even more good help and on dovgo. I am going through the course of prophylaxis once a day. More often in the middle of the season and not so strong, one-day.

Villiziev Kolo

Viliziev colo (circulus arteriosus cerebri Willisii) - the whole anastomosis between the vertebral-basilar and carotid system of blood circulation to the brain. Vin is located in the subdivision of the brain and is a border of arteries, which has the shape of an oval with the lowest transverse diameter. I will name my anatomical approval in the name of an English lykar, having described him for the first time.

In the form of the pool, the villiziev stake will take on the fate of the offensive artery:

• Pochatkova part of the rear cerebral artery;
• The back artery is available;
• Supraklinoid part of the internal sleepy arteries;
• Front spinal artery;
• Pochatkova part of the anterior cerebral artery.

Functions of the village stake

Villiziev colo z'adnu skin with sleepy arteries not only between themselves, but with a system of spinal arteries. With the normal development of the village, the stake is right and half of it is symmetrical.

head function Vilizia cola є the prevention of secondary blood loss around the brain, in the event of a failure of the blood flow in one of the arteries.

Ingestion of vilizia cola: symptoms

Normal development of a viliziev cola is developed no more than 50% of people. Most often, there is a pathological process of the arterial system in the development of hypoplasia of the arteries. Aneurysms of the arteries of the brain are also most often opposed to the judgment of the cola.

In case of hypoplasia of sudin vilizia cola, symptoms can be seen as well as normal blood flow in the basins of the cerebral arteries. In general, the pathology appears as a diagnosis of diagnostics during magnetic resonance tomography.

Yak have shown the results of a recent pre-session held by the University of Pennsylvania that the asymmetric development of vilizia cola among children can be the reason for frequent attacks of migraines, which can prevent them from reaching a rotated aurora.

In case of aneurysm of Sudin Villizia Cola, the symptoms begin to develop from day to day until quietly, as long as it is not necessary. At the time of the development of shelter from the pozdzhenoi judges, begin to vitikati in the subarachnoid space. Affected people can fix their headache for their strength, because it is not easy to supervise themselves with tediousness, blues, intolerance of bright light, rigidity of strong muzzles. With significant bloodsteps, a coma or ailments quickly develop immediately into the world.

A lot of people, having learned about those who have є options for the development of a viliziyev cola do not meet the norm, fall into the eyes, vazhayuchi, but they have є seriously ill, Scho vimag of singing therapy. For the sake of justice, no viliziev stakes will be held.

As they already said vishche, іnuyut the development of vilіzіev cola and from them, vazhayutsya the norm, it is far from being developed by the skin people. The judging of the arterial pool is not a stile for blood circulation in the brain, but a clue for compensation of those who are found to be caused by thrombosis, damage cerebral blood flow for a rakhunok transferring blood from one arterial pool to the other. In addition, in a large number of pathologies, the development of the disease cola is not affected.

Is it all the same? I went to the lykarya, saying that everything is fine, but for me everything is even more abnormal, so it’s more painful to sink and grow stronger.

Likar mav on uvaz, for the results of the MRI, there is no reason to accept headaches, then, as it has been revealed, it is hardly possible to see them. Ymovіrno, it is necessary to farther away from obsozhennya.

Galina hello, passed two rocky yak your sin?

PoZSA from two sides, according to PSA - I will not be unreasonable? 2 - Atherosclerotic changes in the brain, creating blood flow through the thermal arms of the MCA from two sides - what is the value? I went through an MRI scan of a strong man, especially at night; Thank you for your feedback.

I don’t know why you’ll be bad.

"Atherosclerotic changes in the brain, creating blood flow through the thermal arms of the MCA from two sides - what is it?" Cerebral blood circulation impairment as a result of atherosclerosis, i.e., cerebral impairment.

About those who also Villiziev colo, are discussed in the statistics. The result of MRI indications for a doctor, who will be deciphered to you by the doctor who wrote the direction.

It’s not getting sick and not diagnosing, but depriving the result of one further diagnosis. Wine is meant for a drug. For vistavlennya diagnosis of a deficiency, a full-time consultation of a doctor is required. Three results of guilt will turn to the doctor, which will send you to follow up.

Earlier, I was in love with the state of the art, sour organism. However, the tsya dumka Bula is simple. At the end of the day, they brought, well, pozіhayuchi, people cool their brain and shrink their praise.

the same ridkisne ill- Kuru ailment. Hvoryut and only representatives of the Fur tribe in New Guinea. Ailments die away in smith. Vvazhaєya, scho the cause of the diagnosis of ailments є the gift of the human brain.

Lyudin's skin is not just unique finger beats, ale and mov.

If the heart of the people does not shy away, then all the same can be lived by stretching out a trivial interval for an hour, showing us the Norwegian ribalka Jan Revsdal. Yogo "motor" zupinivsya for 4 years, then yak fishing got lost and fell asleep in a dream.

American celebrations spent the rest of the day on the Misha and came to Visnovka, where the cavunovy sik began to develop the atherosclerosis of the Sudin. One group of Misha drank water, and the other - kavunovy sіk. As a result of the judgment of another group, there were bullets of cholesterol plaques.

The first choice was in the 19th century. The wine was made on a steam engine and was designated for the taste of life.

People, who sounded regularly, are more likely to suffer from obesity.

Our intestines populate, live and die a lot of bacteria. Oh, you can hit only with a strong increase, ale, if the stench was picked up at once, then you will be poured at the extraordinary cup.

The dentists showed up quite recently. Even in the 19th century, virivati, ailments, teeth were included in the regulations of the zvychay perukary.

In the case of a sick person, the doctor often overestimates the club. So, for example, like Charles Jensen in the period from 1954 to 1994 rr. having survived over 900 operations with a vision of a new affair.

A robot, like people, is not up to the soul, it’s more shorter for its psyche, it’s lower than the robot’s mind.

To snoop even tsikavi medical syndromes, For example, obtrusively encumbered objects. At the slunk of one patient, a yak of the guardian from the society of mania, 2500 foreign objects were discovered.

Our nirkas are built to cleanse three liters of blood in one slime.

Today, women who drink bottles of beer or wine every day, may be advised against breast cancer.

The slunk of the people is uncomfortable to cope with third-party objects and without the likarsky involvement. Vidomo scho shlunkovy sіk building coins.

Nedomovki, rozmalivki, divoche prisvische ... Zhinochi jealous is a mystery for psychologists. We do not see all the mechanisms until the end of the year, which will make people feel strong and powerful.

Villiziyev Kolo: Option to develop in the form of daily life Abo Reduced blood flow, Lykuvannya

Sales and licensing of Willis' stake

At the front of the human brain there is a special arterial border of an oval shape, which is called a villezieva stake. Before entering the storehouse of the artery stake, the transverse overruns are as small as possible; About those functions in the body of the vicon of the Willis colo, how ill they can oppose and how they are correctly diagnosed - far. The Budovi Cola scheme is shown in the image below.

functional options

In organizmі absolutely great people Willis colo є organ, which is one by one, as well as a folding system of spinal arteries.

Alle, only in the body of people there is a blockage of the brain, the brain function is turned on: the Willis colo starts to prevent the blood supply of blood to the brain.

The price is approximately as follows: at the moment of a decrease in blood flow in one or more deciduous arteries, the brain starts to see a lack of luck and life-long conversations, so that I will compensate for the problem and the lack of additional colonic arteries.

Any problems

For dany doslidzhen, the normal development of the stake of Willis should be deprived of half of the people. As soon as the area is given until the end of the day, then the part of the patients with a normally rosy organ can be less.

For some reason, there are misconceptions, for sure.

Also, the main problems:

• Hypoplasia with full arteries. Lack of arteries, how to live the brain, function correctly, given the problem doesn’t show itself to itself, if it’s not familiar to it.
• The inconsistency of the size of arteries from the other sides, the asymmetry of the rounded hedge. Do not be seen yaka will load the life and healthy pathology, some of the short circuits, and in times of great need to be able to determine their functions. According to the results of the last few days, there is a problem that can provoke some of the attacks of the migraine.

Villiziev colo rosimknuti. Nayseryoznіsha situation, how cleverly podіlyayut on two groups:

• povna (at times underperforming or sounding) and disreputable (with the presence of the back arteries). The option of developing a stake of Willis at the sight of the bloodstream is very important.
• Another common problem is aneurysm, and about it - dal.

about aneurysms

Often, aneurysms of the brain of the brain are localized by the same colo of Willis. V to a young person aneurysm, as a rule, is the result of abnormal budovi cola.

In adults with aneurysms of the Willis Cola in a large number of cases, one of the onset pathologies:

• atherosclerosis;
• infectious vasculature;
• syphilithic endarter.

The main reason for all these problems is: pathological judgment process, which is the result of the destruction of the judgment.

The last hour of aneurysm does not show itself to itself, as a rule, about the problems of a lyudin at that moment, if an aneurysm breaks out.

Symptoms of this important exercise: rigidity of mutilation, tediousness, blues, unbearable head bill, Sensitiveness to a bright light.

Chim shvidshe lyudin to drink in a lykarnya, tim vische chances to vijivannya, splinters of aneurysm growths, a great wikid of blood, which can lead to shvidkoy death.

Rise to sew up, for the necessary therapeutic visits of people living in everyday life.

About likuvannya

In fact, Likuvati of the Willis colo does not seem to be moody. Any anomalies in development are not recognized as a reason for the operation.

If the patient is suffering from migraines, who suffer from anomalies of arterial cola, they are not surrounded by the signs of strong antibiotic drugs.

Problems with the organ are easy to detect and diagnose for additional magnetic resonance tomography. In a large number of cases of anomalies, they appear vividly in the diagnosis of other organs and systems.

Yak rule surgical involvement stagnate at that moment, if aneurysms are opened. In some cases, it is necessary to carry out an operation until the moment of breaking up aneurysms, but in a large number of cases, it is possible to use a conservative variant of treatment.

Vіllіzіev colo, which is practically not carried out, is an important and folding organ of the human body.

Remember the symptoms of aneurysm development: it is possible to vryatuvati your life.

Funny and serious

An option for the development of a viliziev cola in the vigilia of the daytime signal from the blood flow along the right posterior cephalic artery. An option for the development of a viliziev cola. Sound education of the spine artery. A change in the cognitive and diffuse character in the speech brain is not revealed. Villiziev colo z'adnu skin with sleepy arteries not only between themselves, but with a system of spinal arteries.

With the normal development of the village, the stake is right and half of it is symmetrical. The head function of the cola is the prevention of secondary blood loss to the brain, in the event of being a cause of impaired blood flow in one of the arteries. Normal development of a viliziev cola is developed no more than 50% of people. Most often, there is a pathological process of the arterial system in the development of hypoplasia of the arteries.

Inception of the viliziev stake: likuvannya

In general, the pathology appears as a diagnosis of diagnostics during magnetic resonance tomography. In case of aneurysm of Sudin Villizia Cola, the symptoms begin to develop from day to day until quietly, as long as it is not necessary. For the sake of justice, no viliziev stakes will be held. As they already said vishche, іnuyut the development of vilіzіev cola and from them, vazhayutsya the norm, it is far from being developed by the skin people.

Functions of the village stake

With the presence of aneurysms, one of the arteries of the vilizia cola is the treatment of surgical and polyagus in the ligation of aneurysms. In quiet cases, if aneurysms are infused, conservatively Also, like if you have subarachnoid hemorrhage, be it the cause of the wicked.

I'm going! At least 21 years old, I had a severe headache, and I was already close to fate from day to day, because of the MRI of the head and many pathologies, not just osteochondrosis. I'm going! I’m 49 rocky, and I’m mindful, but all the sores are less likely to occur (so it seems to me in drug settings).

Duzhe got used to living in the whole camp. Incomplete вілізієve colo. Decreased blood flow along C2 according to Krilov, segments of the ICA from two sides. It is very reasonable and necessary for the hospitalization. Live the stench in the village. With a series of analyzes, your sister will need to go to the neurologist, so that it is necessary to determine everything seriously and if necessary. It is also painful for people. Heroin, for example, a collection of buv vivements on the market like a child's cough. And the cocaine is recommended by the drug in the form of anesthesia and as an increase in vitality.

At the slunk of one patient, a yak of the guardian from the society of mania, 2500 foreign objects were discovered. If the heart of the people does not shy away, then all the same can be lived by stretching out a trivial interval for an hour, showing us the Norwegian ribalka Jan Revsdal.

More periodically. The 4th time, the judges burst in the eyes, their eyes were all crooked and at the same hour, there was a strong headache. Passed through, there were no signs of failure in the assessment. VISNOVOK: MRA is a picture of blood flow reduction and diameter ringing on the inside of the artery.

The neuropathologist prescribed instenon in tablets for 1 month, and for headache diclofenac for 3 days. At the reception I didn’t recognize any more. Good day, The fierce rock didn’t feel good post_in_ boli in the area of ​​the head and the side of the head.

An option for the development of a viliziev cola. Infiltrative changes in the mucous membrane of the upper slit sinus

On the MR series, tomograms are important for T1 and T2 in three projections of visualized sub-and supratentorial structures. bicnі slunochki to the brain of extraordinary sizes and configurations. The subarachnoid convexital space is locally unevenly expanded, especially in the area of ​​the frontal and short lengths. middle structures do not vindicate.

MRI Doslidzhennya: “MR picture of structural, degenerative changes in the area of ​​basal structures and the middle brain, enriched with added manganese-containing pigments.

What does it mean manganese-containing pigments and the smell of stench can be seen in the eyes? On a series of MR angiograms, displayed in TOF modes, in the axial projection of visualized internal sleep, the main intracranial segments of the spine arteries and branching.

Low asymmetry of blood flow along the spinal arteries

From the statistics, you can understand: what options are available for the development of a viliziev stake, which also includes arteries to enter its warehouse. You can get sick because of the pathology of the disease.

Date of publication of the statistics: 19.06.2017

Date of update of statistics: 07/29/2019

Vіllіzіev colo (faster VC) - the whole system of anastomoses (z'єdnan mіzh vodinam) blood-bearing vasculature, spaced in the subdivision of the brain. Winning protection is more important for the systems of internal sleep arteries and the VERTEBROBASILAR pool.

Before the warehouse of VK, there should be a number of arteries, yak, z'ednuchis among themselves, set up a colo. In most cases, there are a number of closed circuits, but for some people, we can see one of the Sudins, through which we are old. They call it options. Deyakі z cikh options development can lead to an increase in the risk of poor cerebral disease, such as aneurysm or stroke.

Protect the majority of people have different options for VK physiological norm, so that the stench does not affect any symptoms but rather inherited ones.

So, as the acceleration of the wrong development of the viliziev cola appears in the brain, neurosurgeons and neurologists are engaged in them.

Budova Villizieva Cola

The brain is not an excess of the organ in the human body. It is not surprising to him that this blood posture is one of the priority goals of the heart-vascular system. Mozok will take shelter from two dzherel - from the system of internal sleepy artery and from the vertebrobasilar pool.

In order to unify catastrophic inheritances when one of the great vessels is overrun, between two blood circulation systems, anastomoses can be formed, so that the base of the brain of Villizia colo is formed.

VK is stored in three pairs of main arteries:

1. The anterior cerebral arteries (PMA) are seen from the internal sleepy arteries.
2. Internal sleep arteries (ICA) - before the VK warehouse, the thermal part is included, before the middle cerebral arteries (MCA).
3. The posterior cerebral arteries (ZMA) are the endocrine arteries of the basilar arteries (BA), as they become part of the evil spine arteries (PA).

For the completion of the stake, two other blood-bearing judges are also present:

1. The anterior spinal artery (PSA) is one between two PMA.
2. Rear arteries (ZSA) - heads of the Arteries of the Armed Forces, which lead to the ZMA.

Yakshho Villiziyev has a number of closed circuits, the shelter can, if necessary, pass through the anastomosis from one artery to the insha.

Options for VK development

Turn on the VC, in which there are no outside or underdeveloped (hypoplastic) warehouses, only 20-25% of people are developing.

There is a great number of available options for anatomical budov and development of VK. The most widespread from them:

• hypoplasia of one or two ZSA;
• hypoplasia or the visibility of the PMA segment;
• PSA hypoplasia;
• the visibility of one of the ZSA.

In practice, it means the development of VK

Asymmetry of budovi VK is to produce blood flow asymmetry and an important factor in the development of internal cranial aneurysms and ischemic strokes. The price of destruction is known to be found in young patients, in some VK roznutsy between buildings until compensation gostrych changes in the arterial blood-postulated brain.

Before the development of the chicks, they are ill, or they do not know about those who have anomalies in the development of the brain.

Sudin VK aneurysm

Aneurysm is the key to the vascular endowment. Sudin aneurysms, which enter the VC, are the most common cerebral aneurysms. The most frequent odors are found in the PSA, at the bifurcation (duplication) of the BCA and in the ZSA, at the bifurcation of the BA.

The majority of cerebral aneurysms do not show any symptoms to their full extent. However, with great changes in vipinnya, it is possible to reduce the size of the spaced handles of the tissues of the central nervous system, which in some people can be reduced to:

• double in the eyes;
• expansion of the site;
• vinnennyu pain behind the apples;
• headache.

With the development of aneurysms, Sudin, which is included in the VC, develops hemorrhage in the space near the brain (subarachnoid hemorrhage), until symptoms of which lie:

1. Raptova with an important headache.
2. Nudota and blues.
3. Skoost in shia.
4. Timchasova vrata zoru abo svіdomosti.

Ischemic stroke in case of small variants of Budov and VK

Disruption of the symmetry of blood flow through the arteries of the brain can lead to the development of atherosclerotic lesions, which leads to an increase in the development of ischemic insult. VK opening will not provide good collateral blood flow;

Symptoms of an ischemic stroke:

• Rapt destruction of evidence, destruction of evidence.
• Raptovo destructed to the zoru.

Diagnostics: identification of options in Budov and Villizia Cola

In most people, VK non-closure does not manifest itself. The development of a cola cola and this option is most often vivid, when the brain is judged for some reason.

If the patient has symptoms of non-invasive cerebral aneurysms, the following should be done:

• CT-angiography is a non-invasive (that is, without penetration into the body) X-ray examination, before the time for visualization of the brain is injected into the bloodstream of a contrasting speech line, and then a computer tomography is performed.
• Magnetic resonance imaging is a non-invasive method, such as a vicious magnetic field and radio frequency impairment for removing a detailed image of the brain.
• to the brain - a special catheter is started in the artery of the brain. Contrast is injected through the catheter and an X-ray sign is sent.

Lіkuvannya options for the development of a vіllіzіeva cola

According to its own options, the development of VK does not є become ill and does not require treatment. Also, the presence of aneurysms called for the development of aneurysms or an ischemic insult, to carry out the treatment of ailments.

The brain system of the brain grows into a folding bud. One of the key warehouses is the number of villas, which is a closed complex of arteries, which can be stored from the rear and front upper and lower vessels, so that the blood flow to the base of the brain is prevented. The managers of the given system will create the correct blood supply in the event of the destruction of robotic sleepy arteries, so be it pathology in the development of the complex it would be good to lead to negative inheritances.

SHO TAKE VILLIZIEV KOLO

The system of sudin is given - by the mechanism of brain damage, compensation of damaged blood circulation in case of severe arteries. With the development of obstruction, a loss of abnormal growth of the vessels, anomalies of the arterial bed are diagnosed. In the presence of a whole court of the protilezhny side, they take on the function of blood posture, transferring the roof along collaterals - the back of the court. At normі to navіt with abnormally rosy arteries of vilіzіeva stake, lyudin does not see any features of the haunting robots in their arteries.

functions

Basically, the establishment of the viliziev cola is the preservation of the blood supply of the peonies to the brain. Particularly important is the function of the system in case of impaired blood flow in the vessels of the shia, which will block the sore starvation of the brain and wiklik. rіznі ailing... Zabezpechennya pracezdatnostі kіltsya zaddyashayasya that, that the dream arteries are tied not only by themselves, but the first one with arteries of the ridge. A scheme is given for the transmission of the brain with the necessary lively words.

budova

arterial colo great brain to be located in the pidpavutinny area, soak up the health of chiasm and the middle of the brain with your elements. Classic Villiziev number of stocks from:

• anterior cephalic artery (PSA);
• cob forms of the anterior cerebral arteries (PMA);
• posterior cerebral arteries (PCA);
• supraklinovid part of the internal sleepy artery (ICA);
• posterior cranial arteries (PAS).

All the judges will make the shape for a seven-yoke ride. With a whole ICA, transfer the roof from the retinal sleepy arteries to the cerebral and PMA, resulting in both the anterior arteries being unaffected. ZMA take the cob from the main one, the yak is set up by the path of the ridge Sudin. The posterior artery, whether it is the ICA or the ZMA, will be eliminated from the basilar or internal sleepiness.

So, to pretend to be a circle, I’ll get the links of two arterial streams, and parts of the building’s brothers on themselves with the function of blood supply to quiet zones of the brain, which are incomplete lively speeches in the event of a ringing or blockage of some of the elements of the cerebral fissure. Sleep and anterior cerebral arteries appear to be maximal in duration, and in the case of a wide range of cerebral arteries and cerebral arteries, they are characterized by variable development and individual features of the distribution. The breakdown of the symmetry of the Sudins is the norm: the livy segment of the middle artery tovshchu, nizh praviy.

Options for the development of viliziev cola

There is a great number of options in Budov and viliziyev systems, because of them there are some anomalies - the aplasia, traffic, hypoplasia, the number of singing arterial types of events, pr. Variants of budovi viliziev cola to be implanted for additional invasive and non-invasive diagnostic methods (angiography, CT angiography, MR-angiography, MRI, transcranial dopplerography).

Diagnostic procedures are carried out when specific scargs of a sick person are evident, in those cases they appear vividly. The norm (the classic Budov viliziev cola) grows deprived in 35-50% of people. Tse established in respect of the specificity of the budov and the judiciary system and the brain of the individual specialty of the skin people. Tim is not the least, the actions of the Villizia cola are abnormal, for example, the subordinate of the Sudins, but those who see it, are not very susceptible and often do not detect the process of failure.

Illness and pathology of the vilizia cola

The anatomy of the transfer to the foldable budget of internal systems, for the reason why it is optimal for the robot to be taken care of. Protect, through singularity, do not depend on certain factors, which make it worse for the development of organs / systems, including Villizia colo. As a rule, anomalous variations in their development are manifested in the asymmetry of arterial blood vessels, or in the presence of certain children. Often warehouses close the circle of the court may have a different diameter, in some cases the localization is shown. Deyaki vidhilennya to produce pathological inheritance, described below.

aneurysm

This phenomenon is a type of artery called, with which often localization of pathology is to serve the Villeziev colo. In young patients, aneurysm, as a rule, is the result of an abnormal growth of the vascular system and the brain. In some adults, aneurysms often have one of the onset problems:

• infectious vasculitis;
• atherosclerosis;
• syphilithic endarter.

Vidhilennya is often asymptomatic, while not trapping aneurysms, scho bleeding into the brain. Symptoms of this manifestation:

• intensive headaches;
• blues, nudota;
• gostra reaction to yaskrave svitlo;
• coma (as if you didn’t bully live in the therapy).

hypoplasia

Decreasing the parameters of the Sudin serves as an inheritance of the wadi development of the Villizia cola. When there is a lack of blood flow in the brain basins, the hypoplasia is asymptomatic. Dana ailment may have been revealed by an MRI scan. The reasons for the congenital anomalies to be scared in the destructions of the intrauterine development, wiklicans:

• postpone the hour of vaginosti by deyakimi infectious pathologies;
• fall, belly blows before the hour of sucking the fetus;
• implantation of vaginal otruynykh, teratogenicity, otruynykh speech, including alcohol, drug type, drugs;
• we will cover it with an anamnesis.

aplasia

Stan, when there is a number of non-closures through the visibility of the back of the brain, is called aplasia of the back arteries of the brain. Anomalies can be observed in the anterior view, ale earlier. Even though the artery of the presence, the ale is weak, it is diagnosed in the general community of closures of the Villizyev colo. The cause of the manifestation is the zupinka development of the fetus in the middle of the womb.

The aplasia of the anterior lowering vessel does not allow the blood supply to the damaged brain for the additional delivery of blood from the lower vessel through the arteries. When the ZAA is not formed, there is no connection between the back and front zones of the viliziev cola, and the anastomoses are not cleaned. Tastes and prognosis of such an illness is unpleasant from the point of view of unpleasantness of decompensation of blood flow damage.

Trіfurkatsіya

The anomaly is characterized by splitting of the sudini into 3 elements. Given pathology Sposter approximately at a third of vipadkіv and do not represent safety, for now there is no sign of occlusive changes. It is a basic front and rear traffic, which is formed in the period of the embryonic development. In some cases, anomalies accelerate, in the case of aneurysms, atherosclerosis, hypertension, headache may occur, and the disease is rare. As a rule, there are no neurological symptoms that do not appear, so the special treatment of traffic is not visible.
