Dural arteriovenous fistula (dAVF) Presenting as Hemmohragic Stroke

A dural arteriovenous fistula (DAVF), is an abnormal direct connection (fistula) between a meningeal artery and a meningeal vein or dural venous sinus. In cases where there are multiple fistulas, the related term duralarteriovenous malformation (DAVF) is used.
