Abstract:
A 44-year-old male with right vertebral arteriovenous fistula accompanied with tinnitus, underwent endovascular treatment using GDC. A digital subtraction angiography clearly showed one fistula flowed from the right vertebral artery (VA) to the vertebral venous plexus, while the right VA close to the fistula was interupped with HyperForm. The tip of the micro catheter was placed in the vertebral venous plexus through fistula from the right VA, and the vertebral venous plexus around the fistula was embolized with 4 GDCs. Blood flow of the right VA was maintained. Follow-up angiography undertaken 6 months after the operation didn't show the recurrence of arteriovenous fistula.
