All patients were cured and 94.1% of internal carotid arteries were preserved. Proptosis, bruit and chemosis disappeared following embolization. The diagnosis and management of TCCF are also evaluated.展开更多

A few cases have been reported in literature to be related to diagnostic cerebral angiography and orbital venography. Several mechanisms have been postulated, including irritation of the vessels from contrast media, compression of the carotid artery and reduced blood pressure from general anesthesia. In our own series of about 400 patients at Ramathibodi Hospital, the incidence is approximately 1.75%.CASE PRESENTATION We present a case, which spontaneous closure occurred during attempted endovascular embolization. A 45-year-old woman with left TCCF was referred to our hospital for endovascular treatment. Cerebral angiogram revealed a small-hole fistula at the posterosuperior wall of C2-3 segment of the LICA. Transarterial balloon failed due to the small size of the fistula and acute retroangulation of the balloon attached microcatheter. Transarterial GDC coil placement into the first venous pouch was then attempted for two times, but was unsuccessful. During repositioning of the microcatheter for a third attempt, spontaneous closure of the fistula was observed and confirmed by control angiogram. CONCLUSION Spontaneous closure of direct traumatic carotid cavernous fistulas may occur during endovascular procedures, which can be caused by dissection of the venous pouch by the microcatheter or coils during manipulation, irritation of the vascular walls from the contrast media and decreased blood pressure from general anesthesia.展开更多

In 2005, we treated such a case via transvenous approach using coils and N-buty-2- cyanoacrylate （NBCA）. The causes of recurrent cavernous sinus DAVF and its endovascular approach are discussed.展开更多
