Endovascular Embolization of Fistulous Component of Gamma Knife-treated Arteriovenous Malformation in a Patient Presenting with Delayed Hemorrhage

Abstract

Aim: The rationale basis for treatment of cerebral arteriovenous malformation is total obliteration of the arteriovenous malformation (AVM) with normalization of cerebral vasculature and flow hemodynamics. Presence of fistulous component has been identified as one of the causes of failure of gamma knife therapy in these cases. Case report : We present a case where the patient presented with rebleed due to associated fistulous component which was then subsequently succesfully treated with endovascular embolisation.
