Malformation of brain vessels: what is it?
Malformation of cerebral vessels is called congenital affection of the blood system in which it develops. In the result, the veins, arteries and capillaries are joined together incorrectly and cause serious problems with blood circulation. Usually the first symptoms appear in 10 to 30 years, though it may be a later manifestation of the disease.
The exact causes of this congenital pathology is unknown. Doctors suggest that the problem may lie in prenatal injuries to the fetus. Therefore, every expectant mother need to protect yourself from falls, fainting, and other situations that may affect the position of the baby in the womb. In addition, malformations of blood vessels and can cause injury to the baby during childbirth. Pregnant women need to plan ahead for the birth of a child, to find an experienced midwife and a qualified physician. It is better to abandon the «fashionable» home birth because they can not only cause trauma to the baby and cause his death because of delayed medical assistance.
Please note that any malformations of the circulatory system of the fetus occur no later than 10 weeks of pregnancy. That is why you should carry out a comprehensive examination in the first trimester and a responsible approach to the planning of pregnancy. The disease appears equally in men and women, and not depend on their age.
There are 9 basic types of flow malformations of cerebral vessels. It is logical that each species differs from the other typical manifestations and other features. Most often (about 70% of patients) is found hemorrhagic type of the disease. In this case, the patient was worried about consistently high blood pressure at small sizes intertwined with each other affected vessels. Meets and torpid the option in which «bundle» of vessels much larger in size and is located in the cerebral cortex.
Pressure fell below normal?

In most cases the disease is asymptomatic until severe damage of the arteries, veins or capillaries. Most often patients with a malformation go to the doctor only after the rupture of the vessel, which is accompanied by internal bleeding. The most characteristic manifestations of the different types and stages of AVM embolization include:
- Throbbing headache.
- Epileptic seizures are expressed in varying degrees.
- Reduced sensitivity of some areas of the body.
- Lethargy, some hesitation.
- Weakness, decreased performance.
- Violation of coordination of movements, changes in gait.
- Paralysis or paresis.
- Disturbance of consciousness, etc.
To detect abnormalities of the vessels used a group of diagnostic procedures. The most effective are computer and magnetic resonance imaging and contrast angiography. MRI and CT — the methods of examination, which often reveal malformations of cerebral vessels. And most often it happens by accident, because the person does not feel himself any affection of the blood system.
The most accurate way to contrast angiography. This x-ray technique in which the patient is intravenously injected radiopaque substance and then x-rayed the head x-rays. Unfortunately, the method is dangerous possible complications, so not used very often. Is contrast angiography in modern medicine, the use of superselective angiography. In this case, the radiopaque substance is injected into the body not into a vein and directly into the desired artery through a catheter.
Therapy medical methods are used only as auxiliary treatment. To eliminate the disease used open surgical interventions, accompanied by opening of the skull. Also effective is endovascular embolization — the introduction through a thin flexible catheter into the affected artery of a special drug, which causes blockage of the lumen of the abnormal vessels. The method does not give an absolute guarantee of cure, so it is usually used only after non-invasive radiosurgery.
Non-invasive radiosurgery is used for the treatment of patients in whom beams of the affected vessels are small and located deep in the brain. This method is non-invasive. It is characterized by the influence of thin beams of radiation to the affected artery from different angles. It has virtually no effect on healthy tissue, but it destroys the abnormal. The problem with this technique is that it increases the risk of bleeding in the brain. Alas, folk, and traditional methods of treatment are ineffective. Therefore, do not self-medicate and consult a specialist — this will help prevent possible complications and deterioration of health.
