Introduction: Acute renal failure is a common complication after elective repair of an infrarrenal aortic aneurysm; however, the incidence varies according to different studies. There is still controversy on whether it is more frequent in patients undergoing endovascular repair as opposed to open surgery.Objective: To determine the incidence of postoperative acute renal failure in patients with infrarenal abdominal aortic aneurysm undergoing elective repair by open technique versus endovascular repair at Fundacion Cardioinfantil - Instituto de Cardiologia (Bogota, Colombia) in the period between 2002 and 2014.Method: We conducted a retrospective cohort study that included 326 patients with nomruptured infrarenal aortic aneurysm who underwent open surgery (n = 273) and endovascular repair (n = 53). Results: No statistically significant difference was found between the incidence of acute renal failure in the open treatment group and in the endovascular therapy group (11 % Vs 3.8%) (p 0.1), The history of acute myocardial infarction odds ratio (OR): 4.21; 95% CI 1.65- 10.74, p 0.003) and receiving red cells transfusion (OR: 2.65; 95% CI 1.16- 6.09, p 0.021) appeared as the most important risk factor for the development of acute renal failure. Conclusions: In this study we found that there is no difference in the outcome of postoperative acute renal failure comparing both techniques. However, previous myocardial infarction and the requirement of postoperative transfusion are associated with acute renal failure.
