INTRODUCTION In 1950 we analyzed the results of lumbar sympathectomy in 100 patients suffering from arteriosclerosis of the lower limbs.1 It appears desirable to analyze the results again, since the follow-up period at the time of the initial report was short, averaging 20 months. We may briefly review the material previously presented. The group probably comprised a fair sample of the disease. Twenty-seven of the patients were diabetic. There were 79 men and 21 women. Their ages varied from 34 to 82, with the majority in the upper age groups. Serious disease in the vital organs, especially the heart, was noted in 39. The major limb arteries showed moderate or severe occlusion in all patients. There were two postoperative deaths and six thigh amputations within the first eight weeks. A seventh thigh amputation was performed on one of the patients who died The five-year status will be considered under
