Leriche syndrome ia a common entity which causes ischemia of the lower extremities. Since the introduction of aortic resection and homograft replacement by Oudot in 1951, reconstructive procedures to restore distal blood flow by either endarterectomy or, later, with prosthetic graft have become standardized. Recently we experienced a case of Leriche syndrome. A 50 year-old male patient admitted with intermittent claudication, impotence, and symmetrical atrophy at lower extremities. Aortogram revealed complete obstruction at infrarenal abdominal aorta and Doppler sonogram revealed only minimal blood flow at left femoral artery.Successful surgical treatment was accomplished with endarterectomy at proximal left renal artery and a bypass from abdominal aorta at the level of both renal arteries to both external iliac arteries with bifurcated Gore-tex vascular graft. After bypass operation, we did palpate with arterial pulse at both popliteal artery.He was recovered without complication.
