Abstract

We analyzed 20 cases of traumatic carotid cavernous fistula(CCF) during the recent 10 years The results are summarized as follows: 1) In 18 cases(90%), the clinical symptoms & signs of CCF occurred within 2 months after trauma. 2) The sites of fistulae were common in horizontal segment(40%) and at the junction(30%) between horizontal segment and posterior ascending segment of cavernous portion of internal carotid artery. 3) The main draining veins of CCF were the superior ophthalmic vein(90%) and the inferior petrosal sinus(70%). 4) The methods of treatment were occlusion of fistula with balloon(9 cases), occlusion of cavernous ICA with balloon(2 cases), ligation of cervical ICA with Poppen's clamp(4 cases) and trapping(2 cases). Two patients were not treated and another patient was healed spontaneously. 5) The frequency and severity of complication was significantly decreased in cases treated by detachable balloon occlusion than by direct cervical ICA ligation or trapping procedures. 6) The procedure using the self-sealed goldvalve balloon was simple, but had a risk of premature separation and premature deflation.
