However, in many complicated patients, 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 arteriovenous fistulas 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 fistula 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 fistula 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 embolized via the inferior petrosal sinus, 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 headache was found after operation in all patients, 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展开更多

The aim of this study was to assess the endovascular treatment of CAVMs by using a liquid embolic material, Onyx （ Micro Therapeutics. Inc. , Irvine, CA, USA）. Methods From September 2003 to September 2004, Onyx was used to treat 22 patients with CAVMs. Ten AVMS were located in functional areas, 8 in deep cerebral areas, and 4 in the cerebellar hemisphere. The size of CAVMs was about 3 cm in diameter in 5 patients, 3 -6 cm in 11, and more than 6 cm in 6. Results In the 22 patients, Onyx embolization was successful. Nidus occlusion was complete in 3 patients, 〉 90% in 8, 〉 80% and 〈 90% in 6, and 〉 50% and 〈 80% in 5. Complications included transient neurological deficits in 2 patients, and adherence of microcatheter to the site of injection in 2. Conclusions Being non-adhesiveness, Onyx is a safe and satisfactory embolic material in the treatment of CAVMs. But its long-term efficacy awaits further follow-up.展开更多
