Between 1986 and 1992, 7 patients underwent 8 operations for isolated femoral arterial aneurysms. Three patients with iatrogenic pseudoaneurysms underwent direct closures of the punctured hole. Three patients with either arteriosclerotic or mucoid-degenerative aneurysms underwent aneurysmectomy and reconstruction of the femoral artery by means of the graft. One patient with anastomotic false aneurysm underwent aneurysmectomy and patch-plasty. Four years after the surgery, the same patient had a recurrent anastomotic aneurysm, which was resected and replaced by means of the graft. The results were good in all 7 patients, while 3 had minor complications. It is most important to select the appropriate procedure for the isolated femoral aneurysms which develop due to various causes.
