Prophylactic Distal Revascularization and Interval Ligation Procedure During Femoral Vein Transposition Fistula Creation in Patients at High Risk for Ischemic Complications

Abstract

Femoral vein transposition arteriovenous fistula (FVt AVF) is a viable autologous option when upper extremity dialysis access sites have become compromised. High volume flow through the AVF can lead to ischemic complications, including steal syndrome (SS), and may threaten access and limb viability. Risk factors for SS include: age >60 years, female sex, diabetes, atherosclerosis, hypertension, and previous limb procedures. Two dialysis patients, who were at high risk for SS in their lower extremities as assessed during the preoperative evaluation for an elective FVt AVF, had a distal revascularization and interval ligation (DRIL) procedure concurrently performed. At 42 and 24 months from their respective surgeries, both patients are reliably using their lower extremity autologous access sites and have not developed any signs or symptoms of ischemia. DRIL may represent an effective surgical strategy that can prophylactically be used to minimize the incidence of ischemic complications during FVt AVF in carefully selected, high-risk patients.
