Arterial Reconstruction in Elderly Patients

Abstract

The surgical results of primary peripheral arterial reconstruction for arteriosclerosis obliterans during a 16-year period were examined as a function of age. Data in group 1 were of 121 procedures performed on 95 patients aged ⩾70 years and those in group 2 of 215 procedures performed on 148 patients aged ⩽69 years. There was no significant difference between the operative mortality rate of 4% (four of 95) in group 1 and 3.4% (five of 148) in group 2. The long-term mortality rate was 33% (31 of 95) in group 1. significantly higher (P<0.05) than 18.9% (28 of 148) in group 2. The most common cause of death in both groups was cardiac failure. Cumulative 5-year survival rates in groups 1 and 2 were 56.3 and 78.3% respectively (P<0.0001). The cumulative primary 5-year patency rates of suprainguinal bypass grafts in the two groups were 94.2 and 90.4%. respectively, while those of infrainguinal reconstruction were 67.7 and 55.0% respectively. The 5-year cumulative limb salvage rate was 93.1% in group 1 and 92.7% in group 2. None of these differences was significant. The results support an active approach to surgery in elderly patients with peripheral arterial obstruction caused by arteriosclerosis obliterans.
