Endovascular embolism technique has been demonstrated to be the best initial option for treatment of carotid cavous fistula (CCF). Several large series re ports have shown that most CCFs can be successfully occluded via transarterial or transvenous endovascular approach.1-6 This paper reports a case of C CF recurred after endovascular occlusion of intal carotid artery (ICA) proxim al to the fistula. A new technique has been described for transarterial emboliza tion with tungsten microcoils via surgical exposure to ICA, which has not been r eported previously in the literatures.
