To evaluate clinical pattern and operative outcome of atherosclerotic obstructive disease in the lower extremity, surgical experience in 25 patients between September 1987 and June 1994 was analyzed. There were 24 male patients and 1 female
patient. The
age of the patients ranged between 36 and 77 years (mean:60.9 years). Disabling intermittent claudication, rest pain, or ischemic gangrene (or ulceration) was the operative indication. The patients were classified into three groups according to
the
level of obstruction: Aortoiliac level (11 cases/44%), femoropopliteal level (6 cases/24%), and whole level (8 cases/32%). Anatomic bypass with prosthetic graft was performed in all cases:aortobifemoral or aortofemoral bypass in 15 procedures,
iliofemoral bypass in 5 procedures, femoropopliteal bypass in 13 procedures. The perioperative mortality rate was 12%. Two patients received postoperative major amputation. Twenty two patients were followed-up for 1 to 70 months (mean:21 months).
Late
graft obstruction occurred in two patients. The cumulative patency rate at 3 years was 69.5%. The cumulative limb salvage rate at 3 years was 92.0%.
