Recurrence rate of cerebral vascular malformation surgery

The surgical procedures for cerebral vascular malformations include interventional surgery and craniotomy. There are different surgical methods according to the type of vascular malformations. If the arteriovenous malformations are large, most of them can be directly treated by embolization. If the malformations are large, they are often divided into interventional treatment first and then surgical removal of the abnormal vascular nest. For surgical recurrence rate and surgical resection degree has a relationship, there are small vascular malformations, can be completely cured through intervention methods, and for large malformations, its recurrence rate and surgical treatment degree has a relationship, if the whole feeding artery is treated clearly, there is no possibility of recurrence, if because the deformity is large, can not be completely treated, there will be some recurrence, there is 10% to 20% of the possibility of recurrence.
