Abstract    Abdominal aortic aneurysm (AAA)  is the most common aneurysm in human, especially among old patients. It was reported that the incidence of AAA was as high as 5%~9% among patients older than 65 yeas. If complicated with risk factors, such as hypertension, the incidence was even higher. The morbidity was as high as 80%-90% if the AAA  ruptured. Now there are two main kinds of treatment for AAA. One is the classical open surgery, which includes resection of the aneurysm and then reconstruction of the vascular tone. The other kind of treatment is endovascular therapy. The management for AAA during the perioperative  period such as screening the etiology of the disease, manipulation of basic disease, selection of the treatment method and the treatment some complications after operation is very important for the prognosis of AAA.
