Abdominal aortic aneurysms (AAA) are the result of a degenerative process of the aortic wall. The incidence of AAA has increased during the last three decades. Computerized axial tomography is the best method for investigating AAA. For aneurysms of 4-5 cm or more in antero-posterior diameter, the risk of rupture is definitely high and justifies a preventive surgery. Precise evaluation of myocardial function and of coronary circulation may limit the operative risk and may improve the life expectancy. Screening of AAA in populations at risk will allow to survey the natural history of aneurysmal disease and limit the incidence of rupture which keeps a high mortality rate.
腹主动脉瘤（AAA）是主动脉壁退行性变的结果。在过去三十年中，AAA的发病率有所上升。计算机断层扫描是检查AAA的最佳方法。对于前后径为4至5厘米或更大的动脉瘤，破裂风险肯定很高，因此有必要进行预防性手术。对心肌功能和冠状动脉循环进行精确评估可能会降低手术风险并提高预期寿命。对高危人群进行AAA筛查将有助于观察动脉瘤疾病的自然史，并降低破裂发生率，破裂的死亡率一直很高。
