title: Spontaneous occlusion of cerebral arteriovenous malformation following partial embolization with Onyx.
abstract: 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.
