Result of Bypass Surgery for Arteriosclerosis Obliterans of Lower Extremities. Comparative Study on the Aorto-Iliac and Femoro-Popliteal Occlusion / 日本心臓血管外科学会雑誌

ABSTRACT

Patients who underwent the bypass operation during 5 years from 1987 to 1992 in the 1st Department of Surgery, Hiroshima University School of Medicine, were divided into 2 groups; AIOD group (51 cases) had lesions in the aorta and iliac artery, and FPOD group (46 cases) had lesions in the femoral artery and popliteal artery. A comparative study of these two groups was made. There was no significant difference in age, sex, symptom severity, smoking history, serum cholesterol level, serum triglyceride level. The complication rate of peripheral lesions of the AIOD group was 24% and of the FPOD group was 57%. The cumulative patency rate for 5 years of the AIDO group was 100% and of the FPOD group was 61%. The AIOD group exhibited better patency. In addition to the lower complication rate of peripheral lesions, all the AIOD group had underwent reconstruction operation for peripheral lesions simultaneously. The run-off state of the peripheral region may thus possibly be related to patency.
