Obstructive Hydrocephalus Produced by Venous Ectasia of Dural AV Fistula

ABSTRACT

Dural arteriovenous fistula (Dural AVF) is an anomalous shunt between dural arterial and venous channels. About 10–15% ofall intracranial vascular malformation are dural fistulas which represent anomalous shunts among arterial branches and duralvenous sinuses, meningeal, or cortical veins.We are presenting a rare case of dural AVF treated by transarterial embolizationand complicated by hydrocephalus.
