The outcome of conventional elective open repair for infrarenal abdominal aortic aneurysm (AAA) has improved mainly as a result of screening to detect coronary artery disease, the mainrisk factor for morbidity and mortality. Our group's policy is to perform routine coronary angiography in patients scheduled to undergo elective AAA repair. The purpose of this study was to evaluate morbidity and mortality in our department using this work-up strategy. From January 1990 to December 2000 we performed elective open repair on 632 patients, including 580 men (92%) and 52 women (8%). Preoperative coronary angiography performed in 607 cases (96%) revealed significant coronary disease in 53% of patients and led to the decision to propose prior myocardial revascularization in 12.5% of cases. Mortality and morbidity in the first 30 days after AAA repair were 1.4% and 15%, respectively. Analysis with the Cox model showed that the only risk factor for mortality was chronic renal insufficiency. Our data support routine use of coronary angiography prior to AAA repair. Screening and, if necessary, treatment of coronary artery disease that is commonly associated with AAA enhances the outcome of open AAA repair.
