A complication of treatment of posttraumatic carotid-cavernous fistulas by detachable balloon techniques is presented. During occlusion of the fistula, a balloon embolus migrated from the cavernous sinus into the bifurcation of the internal carotid artery. The resultant neurological deficit was immediately treated with hypertension and volume expansion. The patient underwent direct microsurgical embolectomy and suffered no postoperative neurological sequelae. The significance and management of this complication are discussed.
