Intracranial arteriovenous malformation is a kind of cerebrovascular malformation, which is caused by a group of abnormal development of pathological blood vessels, and the treatment methods are as follows: 1, surgical treatment, that is, craniotomy, is the most thorough and effective method of treating cerebral vascular malformations, in the operation, attention should be paid to find the arteries of the blood supply, and to find the drainage veins, and don’t be in a hurry to deal with the drainage veins; 2, radiotherapy, less than 3cm or located in the functional area, location Radiation therapy, less than 3cm or located in the functional area, deep, difficult to surgical treatment, can be preferred to gamma knife treatment; 3, interventional embolization therapy, the treatment process can not be completely embolized, there will be residual, can be used as an auxiliary means of surgery and radiotherapy. Interventional embolization treatment is carried out at the same time of doing whole brain angiography, abnormal blood vessel clusters can be found through angiography, and the embolization material is injected directly into abnormal blood vessel clusters through special means and special pipeline system to embolize the abnormal blood vessel clusters. The disadvantage is that the interventional embolization cannot completely embolize the abnormal blood vessel clusters, and the patients have to undergo radioactive subsidy treatment after the operation.
