Infrainguinal revascularizations in octogenarians and septuagenarians

Abstract

Objective: Severe atherosclerosis is a major contributor for death in octogenarians and a cause of multiple vascular-related ailments, including claudication and limb loss. Advanced age and health may limit the success of limb-salvaging procedures. Mortality, morbidity, and outcome of infrainguinal grafts have been examined in octogenarians and septuagenarians. Methods: After 128 femoropopliteal and 99 femorotibial bypass grafts in 209 octogenarians and 242 femoropopliteal and 166 femorotibial bypass grafts in 383 septuagenarians, survival, primary patency, limb salvage, myocardial infarction and stroke rates were determined. The survival, myocardial infarction, and stroke rates of controls, 1514 octogenarians and 2011 septuagenarians, were compared. Results: After a bypass graft, 5-year survival of octogenarians (54%) and septuagenarians (64%) was similar (P >.2) and was 89% and 89% for controls. The 5-year primary patency rates were 74% for octogenarians and 68% for septuagenarians (P >.2). Five-year limb salvage rates were 86% for octogenarians and 86% for septuagenarians. After a bypass graft, the respective rates of myocardial infarction were 4.1% and 3.9% per year and of a stroke 3.2% and 3.2% per year for octogenarians and septuagenarians, which occurred more frequently (P <.05) than in controls. Conclusions: Death and cardiovascular events are higher after revascularization in octogenarians and septuagenarians, compared with controls, and are related to the severity of atherosclerosis and not age. Patency rates are excellent and similar. Limb salvage procedures should be considered for most octogenarians. (J Vasc Surg 2001;34:133-8.)
