Transvenous embolization with a combination of detachable coils and Onyx for a complicated cavernous dural arteriovenous fistula

Abstract

Because Onyx may be injected via a transvenous approach and the microcatheter is easily withdrawn, cavernous sinus via transvenous catheterization and embolization is a safe and efficient way to treat complicated cavernous dural arteriovenous fistulas, especially those for which operations via transarterial approaches have failed, or spontaneous cavernous dural arteriovenous fistulas.
