Iatrogenic Arteriovenous Fistula of Subclavian Artery to Vertebral Vein with Perimedullary Vein Reflux

Iatrogenic arteriovenous fistula (AVF) rarely develops around the proximal subclavian artery, although open surgical re-pair of this etiology is known to be complicated as deep dis-section is required around the fistula surrounded by dilated veins. In this study, we present the case of a 64-year-old man, who was referred to our hospital, with AVF between the right subclavian artery and the right vertebral vein. He had a history of accidental puncture of the right subclavian artery. An endovascular repair using a covered stent was successfully performed, and the AVF disappeared. Thus, covered stent placement should be considered as the first -line treatment for a deeply developed AVF, if anatomically feasible.
