Abstract

Study Objective

To identify the risk factors of, and develop a prediction model for, postoperative complications of patients undergoing infrarenal abdominal aortic aneurysm (IAAA) repair.

Design

Retrospective analysis.

Setting

Vascular surgery center of a university hospital.

Measurements

The clinical data of 316 IAAA cases were collected from January 2004 to October 2010 at a single vascular center in China. Postoperative complications were observed within 30 days after surgery. Patient-specific and operation-specific characteristics were analyzed in relation to postoperative complications using multiple logistic regression analysis.

Main Results

Overall incidence of postoperative complications and overall 30-day mortality of IAAA repair patients were 48.4% (153/316) and 8.8% (28/316), respectively. Postoperative complications involved pulmonary (18.9%), cardiac (14.2%), renal (7.3%), gastrointestinal (5.4%), neurologic (1.3%), and hepatic (0.9%) systems, and acute arterial embolism of the lower limb occurred in 1.3% of cases. Risk factors were age [> 65 yrs; odds ratio (OR) 1.6], aortic occlusion time (> 90 min; OR 2.4), history of chronic obstructive pulmonary disease (COPD; OR 4.4), emergency operation (OR 6.1), and history of cardiac dysfunction (OR 2.1).

Conclusions

A combination of age, COPD, emergency operation, history of cardiac dysfunction and aortic occlusion time has significant impact on postoperative complications after open IAAA repair.
