Age, Diabetes and Smoking in Lower Limb Amputation for Arterial Occlusive Disease

Abstract

The increased number of amputations for arterial occlusive disease noted in western countries is only partly explained by increasing numbers of the elderly. A prospective analysis of the influence of diabetes and smoking habits was therefore carried out. in 1978-81, 188 lower limb amputees in Lund were examined and classified as non-smokers, ex-smokers, light smokers and heavy smokers. These figures were compared with corresponding figures among age-correlated controls and to a group of hip fracture patients. the material was divided into men and women and into non-diabetics and diabetics. Smokers had much lower mean age at amputation. Out of 188 amputees only 23 were not either a diabetic, a smoker or 80 years or more. the population study indicates a correlation between smoking and amputation for ichaemia. the coincident increase in cigarette consumption in Sweden is illustrated and it is suggested that smoking should be noted as routinely as diabetes at amputations.
