腹主动脉瘤围手术期管理

Perioperative management for abdominal aortic aneurysm

腹主动脉瘤（abdominalaorticaneurysm，AAA）是人体最常见的主动脉瘤，多见于老年人，65岁以上人群患病率高达5％一9％，如果合并高血压等高危因素，其发病率则更高。AAA有自发破裂倾向，一旦发生破裂，其病死率可达80％～90％。目前主要有动脉瘤切除一人工血管置换术及腔内修复术两种手术方式。从AAA的病因筛查、相关基础疾病的控制到手术方式的选择，再到术后相关并发症的处理等围手术期的管理尤为重要，从一定意义上可以决定治疗的效果。

Abdominal aortic aneurysm （AAA） is the most cmnmon 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 fgr the prognosis of AAA.
