We investigated 19 patients (13 males and 6 females) who had undergone major lower extremity amputation caused by arteriosclerosis (ASO), diabetes mellitus (DM), and chronic renal failure (CRF) from January 2001 through March 2005. The average age of the patients was 77.7 years. The average follow-up period was 10.1 months. We conducted an investigation into basic disease (ASO, DM, CRF), high cutting rank, surgical site infection, and prognosis. For the case that merged many basics diseases, survival rate was low regardless of a high cutting rank for one year, and surgical site infection worsened this rate.
