Review Case ReportsBilateral carotid cavernous sinus fistula: a case report and review of the literature.
Carotid cavernous fistula (CCF) is an abnormal vascular shunt from the carotid artery to the cavernous sinus. They are commonly classified based on hemodynamics, etiology or anatomically. Hemodynamic classification refers to whether the fistula is high or low flow. ⋯ First-line treatment consists of endovascular embolization with either a metallic coil, endovascular balloon or embolic agent. It is unclear in the literature if bilateral cases are more difficult to treat or have a different prognosis. Our patient required two endovascular procedures suggesting that endovascular intervention may have reduced efficacy in bilateral cases.
