Inpatient Mortality Following Repair of Abdominal Aortic Aneurysm in a Tertiary Hospital in Tehran

This study was conducted to monitor the rate of inpatient mortality and its associated factors following open reconstruction of abdominal aortic aneurysm (AAA) in a tertiary hospital in Tehran, Iran. This retrospective study was a chart review of 112 patients undergoing open in­frarenal abdominal aortic aneurysm surgery in one of the main tertiary hospitals in Tehran, Iran. Baseline data (demographic data, risk factors) and outcome data (any cause mortality) were available in 106 cases, which included into this study. The inpatient mortality was very high (23.5%). Regression analysis revealed that in-patient mortality was higher in those with age over 70 years (OR=3.028, 95% CI= 1.099- 8.337) and those who developed temporary worsening of the renal function (OR=3.141, 95% CI= 1.071-9.21). High inpatient mortality rate of the AAA reconstruction in this study is alarming. The decrease in the renal function in the wake of infra-renal aortic surgery and also high age seem to be main risk factors of the increased inpatient mortality.
