Atherosclerosis involving the terminal aorta usually is a diffuse process that commonly includes the iliac and femoral arteries. Less frequently, the lesions are limited to the infrarenal aortic segment with normal distal vessels. Patients with isolated occlusion or stenosis of the infrarenal aorta tend to be younger, more often female and have slower progression of atherosclerotic lesions. There is a causative relationship of this well-localized form of atherosclerosis to the use of oral contraceptives and heavy smoking. In 90% of the cases, surgery of these lesions is limited to endarterectomy. End results are satisfactory in a majority of the patients. Percutaneous transluminal angioplasty produces satisfactory early results for concentric stenosis, although long-term results have not yet been established.
累及终末主动脉的动脉粥样硬化通常是一个弥漫性过程，常累及髂动脉和股动脉。较少见的情况是，病变局限于肾下腹主动脉段，远端血管正常。孤立性肾下腹主动脉闭塞或狭窄的患者往往较年轻，女性更为常见，动脉粥样硬化病变进展较慢。这种局限性动脉粥样硬化形式与口服避孕药的使用和大量吸烟之间存在因果关系。在90%的病例中，这些病变的手术仅限于动脉内膜切除术。大多数患者的最终结果令人满意。经皮腔内血管成形术对同心性狭窄可产生令人满意的早期效果，尽管长期效果尚未确立。
