    Abstract:
    OBJECTIVE: To evaluate five risk scoring methods in predicting the immediate postoperative outcome after elective open repair of abdominal aortic aneurysm (AAA). DESIGN: Retrospective evaluation of the Eagle score, Glasgow aneurysm score, Leiden score, modified Leiden score and Vanzetto score in a consecutive series of patients. PATIENTS: Two hundred and eighty-six consecutive patients undergoing elective infrarenal aortic aneurysm repair. RESULTS: Nine patients (3.1%) died in hospital and another 35 (12%) experienced severe postoperative complications. For the Glasgow aneurysm score, Leiden score, modified Leiden score and Vanzetto score receiver operating characteristics (ROC) curve analysis for prediction of in-hospital mortality showed area under the curve (AUC) of 0.749 (p=0.01), 0.777 (p=0.008), 0.788 (p=0.006) and 0.794 (p=0.005), respectively. The Eagle risk score was less accurate for predicting in-hospital mortality. The risk-scoring systems did not perform well in predicting post-operative complications, but multivariate analysis showed that the modified Leiden score was an independent predictor of postoperative complications. CONCLUSION: All scoring systems predict, with reasonable accuracy, the risk of in-hospital death in patients undergoing elective open repair of AAA, whereas the accuracy in predicting severe postoperative complications is less.
