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.

Cajal Bodies & Gems

Cajal bodies or coiled bodies are dense foci of coilin protein. Gemini of Cajal bodies, or gems, are microscopically similar to Cajal bodies. It is believed that Cajal bodies play important roles in RNA processing while gems assist the Cajal bodies. Find the latest research on Cajal bodies and gems here.
