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

抄録

Iatrogenic arteriovenous fistula (AVF) rarely develops around the proximal subclavian artery, although open surgical repair of this etiology is known to be complicated as deep dissection 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.
