Objective:To evaluate the technical aspects

efficacy and safety in the treatment of cavernous dural arteriovenous fistulae （DAVF） by transvenous liquid n-Butyl cyanoacrylate （NBCA） injection combined with coils placement in the cavernous sinus.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 DAVF.
