Saccular aortic aneurysms are eccentrically shaped and are commonly thought to be the consequence of infection of the aorta. However, saccular-type aneurysms can be found independent of any clinical or subclinical infection and can be associated with a penetrating aortic ulcer. Moreover, penetrating aortic ulcers have been described in the thoracic aorta, but there is a paucity of any documentation of this clinical and pathologic entity occurring in the abdominal aorta. The authors describe 2 cases of symptomatic, penetrating atherosclerotic ulcers of the abdominal aorta causing saccular, noninfectious abdominal aortic aneurysms.
囊状主动脉瘤呈偏心形，通常被认为是主动脉感染的结果。然而，囊状动脉瘤可在无任何临床或亚临床感染的情况下出现，且可能与主动脉穿透性溃疡有关。此外，虽然已报道过胸主动脉的穿透性溃疡，但关于腹主动脉出现这种临床和病理实体的文献却很少。作者描述了2例有症状的腹主动脉穿透性动脉粥样硬化溃疡导致囊状、非感染性腹主动脉瘤的病例。
