Transvenous embolization of a dural arteriovenous fistula of the anterior cranial fossa: preliminary results.

We report two cases of a dural arteriovenous fistula of the anterior cranial fossa, one causing subarachnoid hemorrhage and one detected accidentally. The first case was incompletely treated by neurosurgery, and the second one was referred for endovascular therapy. Both fistulas were successfully occluded by transvenous embolization by using electrolytically detachable coils.
