Treatment of traumatic carotid-cavernous fistula using detachable balloon catheters.
The goal of therapy in patients with traumatic carotid-cavernous fistulas is to occlude the fistula, preferably while maintaining the carotid blood flow. Surgical techniques that treat the fistula remote from the cavernous sinus often cannot maintain carotid patency. Various interventional techniques using detachable balloons have been developed. The most common technique uses the endarterial route, introducing the balloon catheter in the neck or the groin. If the balloon is detached in the cavernous sinus, the carotid blood flow will be preserved. A second approach uses the venous retrograde route through the jugular vein, inferior petrosal sinus, and cavernous sinus. Elegant and safe, this method is appropriate when the fistula drains posteriorly. A third approach involves surgical exposure of the cavernous sinus and direct introduction of the balloon. This is sometimes the only recourse when the fistula has been previously treated with internal carotid ligation.
