Traumatic carotid artery-cavernous sinus fistula treated with a covered stent. Report of two cases.

The authors describe the cases of two patients with unilateral traumatic caroticocavernous fistulas in whom a self-expanding covered stent was successfully used to obliterate the fistula after failed occlusion with detachable balloons and coils. They discuss this option as a primary therapeutic modality in cases in which detachable balloons or coils, with or without a bare stent, have failed to obliterate the fistula. The placement of a covered stent to occlude the lesion from the outset may represent a new therapeutic approach to the treatment of these lesions.
