Major amputation in a defined population: incidence, mortality and results of treatment.
Medical records of all patients, from a defined population of 88,000 inhabitants, who underwent major lower limb amputation during 1980-82 were retrospectively scrutinized. The records showed 131 amputations were performed in 106 patients at the district hospital and 22 amputations on 17 patients at the local university hospital, referral centre, altogether 57 men and 66 women. This gave an amputation incidence of 46 per 10(5) inhabitants per year. Of the amputees 47 per cent were older than 80 years. Only two patients underwent reconstructive vascular surgery (at the university hospital) before surgery. Final amputation level was above-knee in 61 per cent of the patients treated at the district hospital. Mortality rates at 30 days and 2 years after the amputation were 23 and 56 per cent, respectively, and the age-corrected survival after 2 years was 55 per cent. For patients who came from and eventually returned to their own homes the mean hospital stay amounted to 184 days (postoperative deaths excluded). After amputation 26 patients were trained to wear a prosthesis and 16 of these used the prosthesis 2 years after amputation. The present study underlines the need for prospective and parallel studies of vascular surgery and amputation as well as analyses of the risk factors involved in lower limb ischaemia in defined populations.
