High Aortic Occlusion: Surgery and Prognosis / 日本心臓血管外科学会雑誌

ABSTRACT

From 1976 to 1993, 13 patients with high aortic occlusion were treated surgically. Bypass grafting from infrarenal abdominal aorta to the iliac or femoral arteries was performed in 9 patients, endarterectomy with patch angioplasty in 2, thrombectomy followed by straight graft replacement in 1 and bilateral axillo-femoral artery bypass grafting in 1. In 9 patients, femoro-popliteal run-off was determined by arteriography before or during operation. Occlusion of the femoral artery was detected in two patients, and femoro-popliteal bypass grafting was simultaneously performed with aortic revascularization. Two patients died in the early postoperative period (1 fulminant hepatitis, 1 cerebral infarction), and 4 patients died in the late postoperative period (2 ischemic heart disease, 1 cerebral bleeding, 1 malignant tumor). In one patient the iliac artery occluded 13 years after endarterectomy. All other patients showed patent grafts and satisfactory conditions. In cases of high aortic occlusion, late postoperative results were satisfactory after anatomical revascularization. Ischemic heart disease and cerebral vascular accident were important concerning late complications. Postoperative careful follow-up is necessary.
