[The dural arteriovenous fistula treatment by embolization]

The transverse sinus is one of the most common locations for dural fistulas. A 43-year-old man with pulsatile tinnitus had arteriography that showed a left transverse dural arteriovenous fistula. We report on the treatment of the fistula with embolization of the supplying arteries. Primary transarterial embolization failed to completely obliterate the fistula and the recurrent symptoms were observed. Subsequent embolization was tried by using PVA (polyvinyl alcohol), spongostan and mechanical detachable coils and resulted in the improvement of the patient's tinnitus. The additional arteriographical finding was microangioma located on the branch supplying the fistula arising from the left vertebral artery.
