Abstract: Objective To investigate the clinical characteristics,risk factors and short-term progno-sis of acute kidney injury (AKI)after abdominal aortic aneurysm (AAA)surgery.Methods The clinical, surgical and laboratory data of 31 4 patients diagnosed with AAA were collected to analyze the clinical character-istics,risk factors and short-term prognosis of AKI following surgery.Results Among 31 4 AAA patients,94 (29.9%)were complicated with AKI after surgery.History of cardiovascular diseases,decreased baseline GFR,longer operative time and intraoperative blood loss >1 L were the risk factors of AKI after surgery (all P <0.01 ).Compared with non-AKI patients,the proportion of use of vasoactive medications and mechanical ventilation was significantly elevated (all P <0.01 ),the ICU stay,postoperative and total hospital stay were considerably prolonged (all P <0.01 ),and the mortality rate during hospitalization was significantly enhanced (1 3.8% vs.3.2%,P <0.01 )in AKI patients.Conclusions The incidence of AKI after AAA surgery is relatively high.History of cardiovascular diseases,decreased baseline GFR,longer operative time and intraop-erative blood loss >1 L are the risk factors for AKI complication after surgery.Postoperative AKI complication is likely to prolong hospital stay and increase mortality rate during hospitalization.
