Abstract
BACKGROUND: Elderly patients with critical limb ischemia are increasingly treated through interventional therapy. The outcome of tibial and peroneal bypasses in octogenarians who were unsuitable for endovascular therapy remains unclear. METHODS: We conducted a retrospective analysis of all patients who underwent tibial or peroneal bypass surgery in our clinic between October 2007 and April 2015. In Group 1 we included all patients 80 years and older and in group 2 all patients under 80 years. Vein was used whenever possible (diameter not less than 3 mm, not more than two segments for sufficient length). Study end points were primary and secondary patency, limb salvage and survival after 3 years. RESULTS: Indications were rest pain in 32.2% and ulcer and gangrene in 67.8%. There were 92 cases in Group 1 (median age, 85 years) and 178 in group 2 (median age, 70 years). Risk factors and indications were similar in both groups except for gender, renal insufficiency and smoking. 30-day mortality was 9.7% in group 1 and 1.1% in group 2 (P = .001). There was no significant difference in 30-day graft failure and major amputation. At 3 years primary patency in group 1 was 58.9% vs 49.7% (P = .058), secondary patency was 73.0% vs 54.7% (P = .007). Limb salvage was 80.1% in group 1 vs 73.0% in group 2 (P = .446), survival was 44.0% vs 71.2% (P = .000). CONCLUSIONS: Our analysis showed good results in octogenarians undergoing tibial and peroneal bypass surgery with regard to patency rates and limb salvage. However, octogenarians had a significantly higher perioperative mortality rate.
