Management options for brain arteriovenous malformations (AVMs) are surgery, radiosurgery, and endovascular embolization. The aim of partial embolization in endovascular treatment is to make total resection possible. However, increased risk of bleeding in partial embolization creates some controversies about treatment options. Spontaneous total occlusion of cerebral AVMs following partial obliteration with embolization agents is a rarely seen condition. We present a case with an AVM vanishing from right posterior cerebral artery which spontaneously occluded following partial embolization with Onyx liquid agent.
脑动静脉畸形(AVM)的治疗选择包括手术、放射外科和血管内栓塞。血管内治疗中部分栓塞的目的是使全切除成为可能。然而,部分栓塞中出血风险增加引发了关于治疗选择的一些争议。在用栓塞剂进行部分闭塞后,脑AVM自发完全闭塞是一种罕见的情况。我们报告一例AVM从右大脑后动脉消失的病例,在用Onyx液体栓塞剂进行部分栓塞后自发闭塞。
