title: [Vertebral arteriovenous fistula as a complication of atlantoaxial transarticular screw fixation--case report].
abstract: We report a rare case of a vertebral arteriovenous fistula that developed as a complication of atlantoaxial transarticular screw fixation. The patient was a 44-year-old male with a history of juvenile rheumatoid arthritis. He had undergone an atlantoaxial transarticular screw fixation for an atlantoaxial dislocation. At 2 months after the surgery, he complained of right-side tinnitus. A selective left vertebral angiography showed a high-flow arteriovenous fistula of the right V2 segment and occulusion of the right vertebral artery at the level of the C3 vertebral body. Endovascular embolization of the arteriovenous fistula was successfully performed using detachable coils. No deficits were observed after the treatment, and the tinnitus disappeared completely. Endovascular coil embolization is currently an effective and safe treatment for the vertebral arteriovenous fistula.
