Outcome after autogenous brachial-axillary translocated superficial femoropopliteal vein hemodialysis access.

OBJECTIVE: The optimal configuration for patients with "complex" or "tertiary" hemodialysis access needs remains undefined. This study was designed to examine the utility of the autogenous brachial-axillary translocated superficial femoropopliteal vein access (SFV ACCESS) in this subset of patients.
METHODS: Patients presenting for permanent hemodialysis access without a suitable upper extremity vein for autogenous access identified by duplex ultrasound mapping and those with repeated prosthetic access failures were considered candidates for SFV ACCESS. Ankle-brachial indices were obtained, and duplex scanning of the superficial femoropopliteal and saphenous veins was performed. Patients deemed candidates for SFV ACCESS also underwent preoperative upper extremity arteriography and venography. A retrospective review of the complete medical record was performed, and a follow-up telephone or personal interview was conducted.
RESULTS: Thirty patients (mean age +/- SD, 54 +/- 15 years; male, 33%; white, 37%; with diabetes, 50%; obese, 21%) underwent SFV ACCESS among approximately 650 access-related open surgical procedures during the study period. The patients had been receiving dialysis for 4 +/- 5 years (range, 0-24 years), and had 3 +/- 3 (range, 0-17) prior permanent accesses, whereas 90% were actively dialyzed through tunneled catheters. In-hospital 30-day mortality was 3%, and the hospital length of stay was 7 +/- 7 days. Fifty-seven percent of the patients experienced some type of perioperative complication, and 38% required a remedial surgical procedure. Hand ischemia developed in 43% of the patients (severity grade: 1, 10%; 2, 7%; 3, 27%), and a distal revascularization, interval ligation was performed in all those with grade 3 ischemia. Thigh wound complications or hematomas developed in 23% of the patients, and arm wound complications or hematomas developed in 17%. The incidence of thigh wound complications was significantly greater (57% vs 9%; P =.03) in obese patients, but the other perioperative complications analyzed could not be predicted on the basis of age, gender, or comorbid conditions. The SFV ACCESS was cannulated 7 +/- 1 weeks postoperatively. The primary, primary assisted, and secondary patency rates were 96% +/- 4%, 100% +/- 0%, and 100% +/- 0%, respectively, at 6 months; 79% +/- 8%, 91% +/- 6%, and 100% +/- 0%, respectively, at 12 months; and 67% +/- 13%, 86% +/- 9%, and 100% +/- 0%, respectively, at 18 months (life table analysis; % +/- SE).
CONCLUSIONS: The intermediate term functional patency rate after SFV ACCESS is excellent, although the magnitude of the procedure and the complication rate are significant. SFV ACCESS should only be considered in patients with limited access options.
