Many studies have been reported concerning the effectiveness of sympathectomy in peripheral arterial insufficiency. The results have been variable since the early studies by Harris,6 Leriche,8 and Atlas.1 Most of these have dealt with changes following sympathectomy and the end-results. In the present study we have surveyed our cases with symptomatic peripheral arteriosclerosis, primarily to determine factors which might be useful in estimating prognosis. These factors, incorporated in a simplified classification, make it possible to estimate the probability for improvement in walking ability, amputation, or death.
One hundred forty patients with symptomatic peripheral vascular occlusive disease were selected for study at the Dearborn Veterans' Administration Hospital. Those with frostbite, phlebitis, or embolus were not included. These patients had received the benefits of all available medical and surgical therapy except use of the arterial homografts. The course of each patient was reviewed on an average of three years
