BACKGROUND: Either suprarenal or infrarenal aortic clamping markedly reduces renal blood flow. This aortic clamping may cause postoperative acute kidney injury(AKI). METHODS: Fifty-four patients undergoing open abdominal aortic aneurysm (AAA) surgery were included in a retrospective study. Postoperative AKI defined as an absolute increase in serum creatinine (Cre) of more than or equal to 0.3 mg x dl(-1) or an increase in Cre of more than or equal to 50% within 48 hours after the end of the procedure. RESULTS: Thirteen patients developed AKI, but none of them required dialysis. The patients with AKI had higher preoperative Cre, longer operation, longer clamp time and more use of diuretics intra- and postoperatively. CONCLUSIONS: AKI occurred in 24.1% of patients undergoing AAA surgery. Risk factors for AKI were preoperative Cre, operation time, clamp time and use of diuretics.
