[Surgery of arteritis in patients over 70 years of age]

Case reports of 176 patients from a total of 385 operated upon for arteritis, and in the over 70 age group, were analyzed; operations for sympathectomy and to treat ruptured aortic aneurysms were excluded from the study. Of particularly poor prognosis were cases of acute ischemia and very severe ischemia requiring immediate amputation. In a general manner, amputations were of poor prognostic significance: in comparison, reconstructive surgery resulted in a lower mortality rate. Figures for mortality as a function of age showed that recovery surgery is often possible in patients of 80 or over. Moderate-term results were good in from 55.5% to 80.9% of cases as a function of type of operation performed. Continued progress during the 5-year period covered by this study has led to diminished mortality and a reduction in the number of amputations necessary.
