THE LATE RESULT OF AORTOILIAC REVASCULARIZATION WITH SYNTHETIC PROSTHESES.
－A TECHNIQUE FOR THE PREVENTION OF LATE ANASTOMOTIC FALSE ANEURYSM－

Follow-up study was carried out on 132 limbs of 102 patients with arteriosclerotic aortoiliac occlusion revasculized with synthetic prostheses. Postoperative cumulative survival rate was 81.4% at 5 years and it decreased markedly after 7 years postoperatively. Cumulative patency rate was 78.7% at 5 years and 54.9% at 10 years. As compared the Patency rate of anatomic bypass group with that of axillofemoral bypass group, the former was better than the latter statistically. Concerning to the concomitant femoropopliteal lesions, the patency rate of the group without the peripheral lesions was better than that of the group with the lesions statistically.
There were four patients who had infection involving the prosthesis with disastrous consequences. The late anastomotic false aneurysm occurred at 15 anastomoses and the mean intervals between the operation and disruption was 50 months. In another one patient, the aneurysmal dilation of the prosthesis occurred about 2 years postoperatively.
Since 1975, 21 anastomoses in 18 patients have been wrapped with the dacron felt to prevent the late anastomotic false aneurysm. In these patients, no anastomotic disruption has occurred. To wrap the anastomoses with the dacron felt was thought to be a disirable technique to prevent the late anastomotic disruption.
