Congenital cerebrovascular malformation?

summary

Cerebrovascular malformations are cerebrovascular, congenital and non neoplastic developmental abnormalities. It refers to the abnormal number and structure of cerebral and local blood vessels caused by cerebrovascular development disorder, and it will affect the normal cerebral blood flow. Its rupture and hemorrhage mainly manifested as intracerebral hemorrhage or hematoma. One of the causes of cerebrovascular malformation is arteriovenous malformation. Arteriovenous malformations can be divided into typical cases and Galen's great venous malformations. Clinical symptoms, in addition to because of space occupying and compression, the blood is also an important reason. Intracranial vascular murmur is more obvious, hydrocephalus can occur in infancy, the mortality is very high, about 50% will die. Let's take a look at the following.

Congenital cerebrovascular malformation?

First, congenital intracranial cystic aneurysm. It is rare in children. It mainly occurs in the internal carotid artery at the base of skull. Atmosphere, anterior and posterior communicating artery, or vertebrobasilar artery. The third is venous hemangioma, which is more common in the cerebral hemisphere, more common in older children.

Second: the patients with supratentorial lesions may have mental disorders, hemiplegia, aphasia, dyslexia, miscalculation, etc. the patients with infratentorial lesions are more common in vertigo, sub test station and gait instability. Intracranial hemorrhage is the biggest harm of cerebrovascular malformation, which is caused by vascular rupture. If it is a deep vein rupture, it will cause intracerebral hemorrhage, or intraventricular hemorrhage.

Third: cavernous hemangioma, more common in the cerebral hemisphere, dense thin-walled vessels. Childhood often asymptomatic, and was accidentally found, generally to the elderly or adults after the symptoms, mainly epilepsy headache intracerebral hemorrhage. Similar cavernous hemangioma of retina, liver, kidney and skin can also be seen in this disease.

matters needing attention

The clinical manifestation of cerebrovascular malformation is also pulsatile headache. Located in the diseased side, it may be accompanied by intracranial vascular murmur. The second is bleeding. Hemorrhage is often the first symptom, manifested as subarachnoid hemorrhage or intracerebral hematoma. The third is epilepsy, epilepsy is the first symptom or after bleeding, mostly generalized or localized seizures.
