Traumatic carotid-cavernous fistulas (CCFs) present the clinician with diagnostic and surgical challenges. Extension of a CCF into the sphenoid sinus presents additional management difficulties. Endovascular interventions using various thrombogenic materials such as balloons, coils, or liquids are effective treatment strategies. Ideally, these techniques are used to obliterate the fistula while maintaining the patency of the parent artery.
