Transvenous embolization with Onyx for a cerebral arteriovenous fistula originating from the distal lenticulostriate artery

Abstract

We described the first case of transvenous embolization with Onyx for a cerebral arteriovenous fistula (CAVF) originating from the distal lenticulostriate artery (LSA). A 16-year-old patient presented with right intraventricular hemorrhage. Angiography demonstrated that CAVF originating from the right distal LSA directly connected to the contralateral basal vein of Rosenthal. We treated the fistula with Onyx through transvenous approach by the balloon-assisted method. CAVF was completely obliterated and remained closed as ascertained by follow-up angiograms.
