Methods： Eight patients with cavernous DAVF, treated by transvenous embolization with combination of detachable coils and glue between February 2006 and February 2009 in our hospital, were retrospectively analyzed, including the clinical presentations, patterns of angioarchitecture, methods of treatment and the results of follow-up. Results： In all 8 patients, 9 transvenous and 1 transarterial interventions were carried out. A single endovascular procedure was performed in 6 patients and 2 patients had to be treated twice. Of the nine transvenous approaches, eight approaches were performed via inferior petrosal sinus （IPS） and 1 via the facial vein. Complete angiographic obliteration was achieved in all patients immediately after the embolization. There was no procedure-related morbidity except for mild headache for one to seven days after the embolization. Clinical cure was achieved in all cases during the clinical follow-up periods, ranging from 8 months to 3 years. The follow-up angiography periods averaged 6.6 months with a range of 5-9 months, in which no recurrence was observed. Conclusion： In this small series, embolization with combination of glue and detachable coils by transvenous approaches was a safe, effective and economical method for the treatment of part of symptomatic patients presenting with complex cavernous DAVE展开更多

Methods: The data of 43 patients hospitalized consecutively with traumatic intractable carotid cavernous fistulas (TICCF) were analyzed. Therapeutic occlusion of ICA was performed on 39 cases and BOT was only performed on the remaining 4 cases. Our assessment consisted of: (1) angiographic evaluation of collateral circulation with or without BOT of ICA, and (2) evaluation of clinical tolerance to therapeutic occlusion of ICA with hypotensive challenge for 30 minutes. Complications of BOT and therapeutic occlusion of ICA were also analyzed retrospectively. Results: Complications related to BOT occurred in 1 case (2.3%) without causing permanent deficits. Complications related to therapeutic occlusion of ICA occurred in 4 cases (10%), including 1 technical (2.5%), 2 temporary (5%) and 1 permanent (2.5%) deficit. There was no fistula recurrence or mortality. Conclusions: BOT of ICA is safe and economical. The reliability of the results is almost the same compared with that of other more complicated methods of assessing therapeutic occlusion of ICA. And it is easy to treat TICCF with therapeutic occlusion of ICA.展开更多
