BACKGROUND: Treatment of cavernous dural @entity2548 (DAVF) is usually made by a transarterial approach. However, in many complicated @entity1 , treatments via transarterial approaches can not be achieved, and only an operation via a transvenous approach is feasible. We aimed to study the feasibility of transarterial embolization of cavernous dural @entity2548 with a combination detachable coils and Onyx to embolize a complicated cavernous DAVF via a transvenous approach. METHODS: From August 2006 to August 2007, six cases of complicated cavernous DAVF were embolized with a combination of detachable coils and Onyx via a transvenous approach. Three cases were male and the other three were female. Their ages ranged from 36 to 69 years old. The @entity292 was in the right lateral cavernous sinus in one case, in the left lateral cavernous sinus in another, and in the bilateral cavernous sinus in 4 cases. One @entity292 was fed by the right internal carotid artery and its meningohypophyseal trunk; one was fed by the branches of the left internal carotid artery and left external carotid artery; four were fed by the branches of the bilateral internal carotid artery and/or the bilateral external carotid artery. One case was drained via one lateral inferior petrosal sinus; three were drained via bilateral inferior petrosal sinuses; one was drained via one lateral ophthalmic and facial veins; one was drained via the inferior petrosal sinus and the ophthalmic and facial veins. Four were @entity999 , and two were embolized via the ophthalmic and facial veins. RESULTS: Among six cases of complicated cavernous DAVF, four were fully embolized with Onyx by a single operation, and two cases were fully embolized with Onyx following two operations. Transient @entity10 was found after operation in all @entity1 , but was cured after several days by the symptomatic treatments. In one case, the first operation via the inferior petrosal sinus was a failure; the feeding branches of the external carotid artery were embolized, and transient @entity3541 was appeared after operation. The @entity292 was fully embolized with @entity50 after two months with no complications. One bilateral cavernous sinus DAVF was embolized with @entity50 by two operations, and transient @entity2896 occurred after embolization. CONCLUSIONS: Because Onyx may be injected via a transvenous approach and the microcatheter is easily withdrawn, cavernous sinus via transvenous catheterization and embolization is a safe and efficient way to treat complicated cavernous dural @entity2548 , especially those for which operations via transarterial approaches have failed, or spontaneous cavernous dural @entity2548 .
