Abstract
This study was aimed to assess the effect of preoperative renal dysfunction on mortality and postoperative renal failure in patients undergoing elective endovascular repair of abdominal aortic aneurysm. A total of 155 patients with a mean age of 74.9 years (+/-6.4) were included. In all, 31 patients (20%) had a preoperative creatinine level of >1.5 mg/dL, whereas 66 patients (42.6%) had an estimated glomerular filtration rate of <60 mL/min. Perioperative mortality was 2.6% with no significant difference between those with and without abnormal renal indices. Long-term survival at 4 years was 30% in patients with creatinine >1.5 mg/dL compared to over 60% in those with normal creatinine (P < .02). The difference in long-term survival was not as significant in patients with normal or reduced glomerular filtration rate (P = .13). However, neither creatinine nor glomerular filtration rate were found to accurately predict survival even though both demonstrated strong predictivity for postoperative renal failure in patients undergoing elective endovascular repair of abdominal aortic aneurysm.
