Abstract
One facet of the generalized disease of arteriosclerosis is discussed and records of 42 patients who had arteriosclerotic popliteal aneurysm seen at the Mayo Clinic since 1940 are surveyed. Operative technics utilized are presented; these procedures should be carried out early in the course of popliteal aneurysm. To delay is to invite the development of severe ischemia which cannot be relieved by any treatment except amputation.
