Landry GJ, et al. - Factors predicting perioperative morbidity and mortality in patients undergoing open abdominal aortic aneurysm repair (OAR) were quantified. Researchers analyzed 240 elective open AAA repairs over 10 consecutive years for patient demographic factors, perioperative variables including blood pressure, temperature, and glucose control, intraoperative factors, and complications including wound, pulmonary, renal and cardiac, and 30-day mortality. Independent predictors of morbidity (any complication) comprised suprarenal clamping, operative time, and low postoperative temperature. Advanced age and operative time were the multivariate predictors of 30 day mortality. Findings thus suggest that morbidity in patients undergoing open AAA repair could be reduced by controlling postoperative temperature, a potentially modifiable factor, and in turn may minimize the early advantage of endovascular abdominal aortic aneurysm repair.
