Risk prediction in patients undergoing elective endovascular repair of an abdominal aortic aneurysm

Abstract Objectives. The aim of this study was to retrospectively evaluate three risk scoring methods in predicting outcome after elective endovascular repair of an abdominal aortic aneurysm. Design. A Zenith stent graft was employed in 205 patients during years 2001-2005. Results. The 30-day postoperative mortality rate was 2.9%. Receiver operating characteristics (ROC) curve analysis showed that the Glasgow aneurysm score (GAS) (AUC: 0.843, p=0.004) and the Giles' score (AUC 0.815, p=0.009) had a rather large area under the curve in predicting 30-day mortality rate. The modified Leiden score was much less accurate (AUC: 0.594). The best cut-off value for the GAS in predicting 30-day mortality was 90 (0.6% vs. 17.9%, p
