Aim:
The aim of this study is to review our endovascular aortic repair (EVAR) experience in Dunedin Public Hospital as well as assessing the applicability of Mount Sinai score and the American Society of Anesthesiologists physical status classification (ASA) in finding which patients will be most likely to benefit from EVAR.
Methods:
A retrospective study of 54 patients who had EVAR from 2000 to December 2009 in Dunedin Public Hospital was conducted. Univariate, bivariate and multivariate regressions analyses were used in assessing the data with the occurrence of postoperative complications and mortality as the primary outcome variable.
Results:
The overall mortality at 30 days was 1.8%. The Mount Sinai score and smoking status were both found to be significant predictors of mortality.
Discussion:
The Mount Sinai score was a good predictor for mortality as it factors in the patient's comorbidities. This study indicates that smoking status was an important factor and it should be added to long-term risk predicting models.
