Onyx versus nBCA and coils in the treatment of intracranial dural arteriovenous fistulas.BACKGROUND AND PURPOSE
 The purpose of our study was to compare the outcome of DAVFs treated with Onyx versus those treated with n-Butyl Cyanoacrylate (nBCA) and coil embolization in a case-control study.  Compared with nBCA and coil embolization, we hypothesized that Onyx embolization for DAVF is safer and has a higher chance of complete obliteration, with no need for post-embolization surgery for the DAVF.


 The chance of not requiring post-embolization surgery with Onyx (81.8%) was significantly higher (p = 0.005) than with nBCA (22.22%).  The complication rate with Onyx (9.1%) tended to be lower compared with that of nBCA (22.22%; p = 0.37).  Procedural time was not significantly different between Onyx (mean 267 minutes) and nBCA (mean 288 minutes) (p = 0.59).  The odds ratio of a DAVF being treated with Onyx and then requiring no follow-up surgery was 17.5 (95% CI 1.97-155.4).


 Our case-control study suggests that Onyx embolization is superior to nBCA and coil embolization in completely obliterating DAVFs, with higher odds of no post-embolization surgery.  We also found that Onyx is safe for embolization of DAVFs, with no associated neurological mortality and morbidity.
