Glasgow aneurysm scores in patients undergoing open surgical procedure for aortic aneurysm

Background To assess the applicability of the Glasgow aneurysm score (GAS) in patients with aortic aneurysm undergoing an elective open surgical procedure in our hospital. Materials and methods A total of 105 patients undergoing elective open surgical procedure between January 2006 and June 2012 were evaluated retrospectively. Glasgow aneurysm score (GAS) was calculated as age+7 points for myocardial disease, +10 points for cerebrovascular disease, and +14 points for renal disease. The best cut-off value for GAS was determined using the ROC curve analysis. Results The hospital mortality rate was 3.8% (4 patients). GAS was significantly lower in patients who survived the operation (76.0514.71 vs. 92.0 +/- 10.8 respectively, p=0.031). The ICU stay was also significantly lower in patients who survived the operation (2.37 +/- 5.23) compared to the nonsurvivors (25.67 +/- 13.80, p=0.001). No significant difference was observed regarding age, duration of hospital stay, and aortic diameter. The area under the ROC curve was 0.818 and for a 100% sensitivity rate, the cut-off value for GAS was 77.5 with a 58.4% specificity rate (p=0.031). All patients with a GAS<77.5 were alive after surgery. Conclusion The GAS appears to be a reliable clinical predictor for in hospital mortality following elective repair of abdominal aortic aneurysm following open surgical procedure.
