[Brain Arteriovenous Malformations:Indications and Treatment Results of Endovascular Embolization]

Brain arteriovenous malformations(BAVMs)are rare, but have a risk of serious intracranial hemorrhage in young adults. Endovascular treatment(EVT)has an important role in BAVM management with various purposes, including preoperative devascularization, volume reduction before stereotactic radiotherapy, curative embolization, and palliative embolization. In this article, the author reviews recent studies on EVT and relevant studies on BAVM management. Although no definitive evidences of utilizing EVT have been provided because of the various EVT outcomes depending upon various angioarchitectures, treatment goals, strategies, and physician's skills, EVT is certainly useful in selected cases. The role of EVT in BAVM management should be tailored to each patient while weighing the relative risks and benefits.
