Background. The study aimed to evaluate long-term patency and limb salvage rates in distal prosthetic revascularisation of lower limbs using complementary arteriovenous fistula and deep vein interposition (AVF/VI).
Methods. From 1992 to 2000, AVF/VI was performed as an adjunctive technique for prosthetic bypass on infrapopliteal arteries in 32 patients with 1 or more failed ipsilateral infrainguinal bypasses, in whom a totally autogenous vein bypass was not feasible. Critical ischemia was the sole indication for surgery with rest pain, non-healing ischemic ulcers and foot gangrene.
Results. Perioperative mortality (within 30 days of surgery) was zero. Five bypasses failed at postoperative day 30, 3 bypasses were prolonged distally, 3 amputations were performed. During the follow-up (1-96 months), 15 bypasses occluded. Cumulative patency was 62% at 1 year, 47% at 2 years, 21% at 5 years and 21% at 8 years. Limb salvage was 66% at 1 year, 57% at 2 years, 53% at 5 years and 53% at 8 years.
Conclusions. Adjunctive AVF/VI proved useful in maintaining patency of infrapopliteal prosthetic bypasses and achieving limb salvage.
