Unilateral iliofemoral occlusive disease: long-term results of the semi-closed endarterectomy with the ring-stripper.
Nowadays, fewer endarterectomies are performed for treatment of occlusive arterial disease; more often a bypass procedure is done. This study investigates whether the results of the semiclosed endarterectomy for unilateral iliofemoral occlusive disease indeed indicate a wider use of bypass procedures for such short obstructions. Ninety-four patients with an obstructed external iliac and common femoral artery, but with patent ipsilateral common iliac and contralateral iliac arteries, underwent 101 operations. Seven of these patients were operated on at a later stage for occlusive disease on the contralateral side. Ninety-three endarterectomies were performed, and an iliofemoral bypass graft was inserted eight times because an endarterectomy was not feasible. Sixty-two operations were performed for disabling claudication, and 39 operations were performed for limb-threatening ischemia. Eighty-five percent of the patients who underwent an endarterectomy for disabling claudication became asymptomatic. Eighty percent of the patients who underwent an endarterectomy for limb-threatening ischemia became asymptomatic or improved to claudication. After endarterectomy no deaths, false aneurysms, or infections occurred. The patency rates at 1, 5, and 10 years were 94%, 83%, and 65%, respectively. We conclude that the semiclosed endarterectomy with the ringstripper of a unilateral obstruction of one external iliac and common femoral artery can be performed with a low morbidity and without deaths and gives good long-term results.
