Clinical analysis of abdominal aortic aneurysms associated with iliofemoral occlusive disease.
Patients with abdominal aortic aneurysm (AAA) associated with iliofemoral occlusive disease due to arteriosclerosis obliterans (ASO) are often encountered clinically, but their clinical characteristics remain poorly defined. We divided 275 patients undergoing aneurysmectomy into 2 groups: 58 patients with both AAA and ASO (Group A) and 217 patients with AAA only (Group B). General characteristics, morphological features of the aneurysms, surgical procedures and operative results were then compared between the groups. In Group A, ruptured aneurysms were significantly less common (p = 0.005) and the aneurysms were smaller (p = 0.0009). The most common cause of death in Group A was acute myocardial infarction (3/7), in contrast to aneurysmal rupture of another arterial segment and malignancy (6/27, each) in Group B. These findings indicate that patients with AAA and ASO represent a subgroup of patients with particular clinical features.
