Axillary to Common Iliac Arteriovenous Graft for Hemodialysis Access: Case Report and Review of “Exotic” Axillary-Based Grafts

Abstract

A 58-year-old Caucasian male with end-stage renal disease and peripheral arterial disease was referred to us for management of his complex vascular access. His vascular access history included a left wrist primary fistula, a left upper arm access graft, a left leg loop graft, and multiple PermCaths in his jugular veins with recurrent infections. Magnetic resonance venography (MRV) of his chest revealed extensive bilateral venous occlusions due to numerous past hemodialysis access catheters. The patient was scheduled for right lower extremity arteriovenous graft placement, but intraoperatively was found to have severe peripheral arterial disease and a thromboendarterectomy was performed instead. Lower body venous imaging demonstrated patent iliac veins. Based on these anatomic considerations a right axillary artery to right common iliac vein polytetrafluoroethylene (PTFE) graft was placed. The graft required revision twice – once for graft ultrafiltration at the arterial end of the graft and once for needle stick infection – but continues to serve as sufficient access after 15 months. Grafts based off the axillary artery have become increasingly popular in recent years and several venous outflow options have been considered, each with distinct advantages. The common iliac vein offers a central location with high flow rate and low probability of infection. Axillary artery to iliac vein arteriovenous grafting may have a place in the vascular surgeon's armamentarium for complex vascular access cases.
