title: Identification of abdominal aortic aneurysm patients with different clinical features and clinical outcomes.
abstract: To determine the clinical characteristics and factors influencing outcome in patients with atherosclerotic abdominal aortic aneurysms (AAA), 526 patients who underwent aneurysmal resection were retrospectively reviewed: Group I had clinical evidence of atherosclerotic occlusive disease; Group II had no evidence of atherosclerotic occlusive disease. The incidence of ruptured AAA, multiple aneurysms, and a family history of AAA was higher in Group II patients. We concluded that patients with AAA and without atherosclerotic occlusive disease in other areas represent a subgroup with peculiar clinical characteristics. In planning operative treatment and during the follow-up period, it should be kept in mind that Group II patients have a higher incidence of aneurysm rupture; the incidence of late pseudoaneurysm is higher; and there is a greater possibility of aneurysm in other arterial segments. It remains to be seen if the pathogenetic mechanism of AAA formation in Group II patients is different from that in Group I patients.
