Selective Transvenous Coil Embolization of Dural Arteriovenous Fistula

Abstract

We herein report three cases of dural arteriovenous fistula (DAVF) in which the venous outlet immediately adjacent to the fistula was selectively embolized. Case 1: A 69-year-old man presented with a subarachnoid hemorrhage (SAH). Angiography demonstrated a DAVF in the left superior petrous sinus. Case 2: A 59-year-old woman presented with dizziness. Angiography demonstrated a DAVF adjacent to great vein of Galen. The DAVF drained through the great vein of Galen with retrograde leptomeningeal venous drainage (RLVD). The basal vein of Rosenthal was enhanced from the great vein of Galen. Case 3: A 51-year-old man presented with an occipital seizure. Angiography demonstrated a DAVF adjacent to the left side of the superior sagittal sinus with RLVD. All three cases were successfully treated by the selective embolization of the venous outlet immediately adjacent to the fistula. Therefore, selective embolization preserved normal venous return.
