Abstract
During a recent 5 yr period 14 patients had pseudoaneurysms as late complications of aortic bifurcation grafts. Severe atherosclerosis was present at the time of the aortic grafts. Subsequent progression of arterial disease appeared to be the usual cause of the pseudoaneurysms which occurred from 2-14 yr later. Of the 23 pseudoaneurysms in the 14 patients, 19 were in the groin. Excision and interposition graft usually worked well. Eleven patients had early benefit. Two early failures were due to infection. The long-term results correlated with success in obtaining adequate arterial outflow. Rupture of pseudoaneurysms, concomitant thrombosis, other complications and diagnostic errors caused operative problems and influenced results.
