Background: Abdominal aortic aneursyms are the most common type of true aneurysm and have a high propensity to rupture, which makes them a significant health care problem. The aim of this study is to investigate effect of the factors on morbidity and mortality of elective operations.

Methods: Between 1985 and January 2003, 95 patients underwent elective abdominal aortic aneurysm repair in our clinic. Mean age of the patients was 64.93 ± 9.24 years (32-90). Preoperative and postoperative risk factors on mortatily and the factors effecting postoperative urea/creatinin elevation were statistically examined.

Results: Early hospital mortality was observed in 3 patients and late mortality was observed in one patient. In univariate analysis of early mortality, there was an effect of risk factors such as chronic renal failure and age but there was no significancy in multivariate analysis about early mortality. Suprarenal cross clamping (p = 0.001), combined coronary artery bypass grafting operation with cardipulmonary bypass (p = 0.002) and having diabetes mellitus preoperatively (p = 0.008) were found to be statistically significant factors effecting postoperative urea/creatinin elevation.

Conclusions: In the postoperative period of aneurysm surgery, renal function disorders can take place in a transient matter. Mortality is releated with the renal failure that is present in preoperative period. Coronary artery disease and diabetes can make the operation more complicated. Therefore, renal functions and coronary artery disease should be evaluated completely preoperatively.
