What causes cerebral arteriovenous malformation?
summary
Cerebral arteriovenous malformation (AVM) is the most common malformation caused by cerebrovascular dysplasia. It accounts for more than 90% of cerebrovascular malformations. Cerebral arteriovenous malformations have feeding arteries and draining veins, and their sizes and shapes are various. Let's share my experience with you.
What causes cerebral arteriovenous malformation?
Hemangioblastoma, also known as angioreticuloma or hemangioendothelioma, is a new organism with the biological characteristics of tumor. In the primitive vascular network stage, blood flow existed in the blood vessels. With the amount of blood flow, the blood vessels differentiated into arteries, capillaries and veins. During this period, cerebral arteriovenous malformation occurs.
There were three layers of extracranial blood vessels, meningeal blood vessels and cerebral blood vessels in the vascular stratification stage. During this period, there were some disorders, such as facial meningeal cerebral angiomatosis. During the period of cerebral angioplasty, the stereotypical channels of cerebral vessels are composed of internal carotid artery, middle cerebral artery, anterior cerebral artery, posterior cerebral artery, anterior communicating artery, posterior communicating artery and basilar artery ring. In this period, the malformation is usually the abnormality of cerebral vascular arrangement. Such as the absence of anterior communicating artery, the patent of primary trigeminal artery or sublingual artery, the formation of arterial window, etc.
At the stage of vascular wall maturation, the vascular wall is mature and perfect in histology. Whether artery or vein, it has relatively complete intima, media and adventitia. There are muscle devices in the middle layer to control the size of the lumen. During this period, the malformation is the defect of vascular wall, which is one of the important factors of aneurysm formation.
