Surgeons avoid creating arteriovenous fistulae in obese patients owing to deep vessels, cannulation complications, and inconsistent outcomes. We describe placing an arteriovenous polytetrafluoroethylene (PTFE) graft between the brachial artery and axillary vein to avoid these complications. A 39-year-old super-obese woman with end-stage renal disease had undergone several hemodialysis access procedures on both arms. We traced the course of the arteriovenous graft course with the patient sitting and lying down. The ideal course was more accurate with the patient sitting; thus, the patient sat when the course was drawn, before lying on the operating bed. The PTFE graft was placed between the right brachial artery and axillary vein, according to the course in the opposite arm. No anastomotic dehiscence or pseudoaneurysm has taken place during 2 years of follow-up. In super-obese patients, the ideal course for arteriovenous grafts should be drawn while they are sitting, avoiding skin folds. This tip could avoid anastomotic dehiscence and pseudoaneurysm between the axillary vein and a PTFE graft.
