An expeditious and precise method for diameter reduction of venous aneurysm causing arteriovenous fistula steal syndrome

Abstract

Clinically significant dialysis access steal syndrome occurs in 1% to 8% of patients. In the present report, we describe an innovative, hybrid option for venoplasty of a cephalic vein aneurysm using a vascular staple device in conjunction with a 6-mm, endovascular balloon placed a few centimeters distal to the brachial artery anastomosis in a 61-year-old man with stage 3 dialysis access steal syndrome secondary to overwhelming venous outflow. The patient experienced immediate postoperative symptom relief. The arteriovenous fistula was immediately accessible for dialysis, circumventing the need for a temporary dialysis catheter. The arteriovenous fistula was functional at 12 months of follow-up.
