A complex cavernous sinus dural arteriovenous fistula secondary to covered stent placement for a traumatic carotid artery–cavernous sinus fistula

Abstract

Authors present the case of a patient with a direct carotid artery-cavernous sinus fistula caused by head trauma in whom a self-expanding covered stent was successfully used to obliterate the fistula. However, at the 9-month follow-up an angiogram revealed a complex caroticocavernous fistula that was completely obliterated with Onyx 18 transarterially.
