ABSTRACT
Objective To investigate the treatment and prevention for postoperative complications of abdominal aortic aneurysm(AAA)in open surgery.Methods 329 AAA patients received open surgery from January 1991 to August 2009.The postoperative complications were analyzed retrospectively.Results 30 d mortality rate was 0.91%,the incidence of postoperative complications was 19.1%(63/329),including cardiac dysfunction in 21 cases,respiratory insufficiency in 15 cases,myocardial infarction in 6 cases,renal failure in 5 cases,arrhythmia in 6 cases,cerebral infarction in 2 cases,artery embolism of lower extremity in 2 cases,wound dehiscence in 2 cases,incisional hernia in 1 case,ecchymoma in 1 case and deep vein thrombosis in 2 cases.One patient died of acute myocardial infarction,one died of renal failure after 20 d dialysis,1 patient died of premature ventricualr contraction and fibrillation ventricular.Other patients recovered well. Conclusions Cardiac dysfunction and respiratory insufficiency are the main postoperative complications of AAA.Preoperative evaluation.careful intraoperative maneuvre and postoperative care ale the key to improve the treatment effectiveness.
