Foot gangrene is the terminal stage in this cases and the pedal bypass grafting is often the only method of limb salvage. Methods: In 2000 to 2004, 64 pedal bypasses were performed in 63 patients with chronic critical lower limb ischemia. Fifty-six (87.5 %) patients had gangrene or ischemic ulcer, 44 (69.8 %) had diabetes. In some of the patients (17.2 %), previous percutaneous transluminal angioplasty of the crural arteries had failed. Preoperative angiographic findings were unsatisfactory in the majority of the patients; the pedal arch was not visualized in 40 (62.5 %) limbs. The cumulative primary and secondary graft patency rates and limb-salvage rate were assessed by Kaplan-Meiers survival analysis. Fishers exact test was used to investigate whether the absence of the pedal arch on preoperative arteriograms was related to an increased risk of graft occlusion. Results: During 60 months of follow-up, 14 grafts (22 %) failed. Early thrombectomy resulting in long-term graft patency salvaged 8 limbs. One limb with graft occlusion, occurring after foot ulcer had healed, was also salvaged. However, one amputation had to be performed despite a patent graft. The perioperative mortality rate was 3.2 %. Cumulative primary and secondary graft patency rates and limb-salvage rates at 60 months were 75 %, 79 % and 82 %, respectively. The 14 occluded grafts were recorded in nine limbs (22.5 %) that, on preoperative arteriograms, had no visible pedal arch (n=40) and in five limbs (20.8 %) with a visible pedal arch (n=24). The difference in the risk of graft occlusion between these two groups was not significant (Fishers exact test, P=1.000). Conclusions: Pedal bypass grafting is a safe method with good long-term outcomes. Since the absence of the pedal arch on preoperative arteriograms does not increase the risk of graft occlusion, unsatisfactory preoperative angiographic findings need not be taken as a contraindication to pedal vascular reconstruction.
