ABSTRACT
We encountered 12 patients with 18 anastomotic aneurysms (AA) between November 1976 and October 1989. Ten of them were arteriosclerosis obliterans (ASO) and 2 were Behcet disease. The interval from initial. operation to reoperation was 65.1±24.0 months in ASO and 7.5±3.0 months in Behcet disease. In ASO, there were no abnormal findings in the prostheses and sutures, whereas the host artery at the anastomotic site widened and weakened. Because the incidence of AA after aortofemoral bypass was much higher in the case with poor run-off at the anastomotic site, it seems to be reasonable to add a distal bypass in the case with poor run-off. In Behcet disease, since AA frequently occurred within the short interval in which anti-inflammatory drugs were given, the arterial reconstruction should be carefully indicated.
