Abstract:
Objective To determine the risk factors for acute kidney injury following type Stanford A Aortic Dissection surgeryies.Methods It's a restrospective study.The clinical data of 176 patients undergoing type Stanford A Aortic Dissection surgery from Septerary 2009 to December 2011 were retrospectively analyzed.There were 115 males and 61 females with mean ages(43.20 ± 10.14)years old.The patients were divided into two groups according to whether AKI occurred after operation.Univariate and multivariate analyses were used to evaluate possible pre-,intra-,and post-operative parameters associated with AKI according to AKI Network.Results Among all the patients,AKI occurred in 78 (44.32％),21 (11.93％) of whom underwent continuous renal replacement therapy (CRRT).In hospital mortality was 3.41％ in all discharges while 6.45％ in AKI patients (P ＜ 0.01).Conclusion Multivariate Logistic regression analysis revealed that increased age,pre-operative left ventricular insufficiency,pre-operative renal insufficiency and long extracorpeal circulation (CPB) time ＞ 140 min were risk factors for the development of AKI.AKI is the most common complication of type Stanford A Aortic Dissection surgery,and is the risk factor of mortality after the surgery.It is important to enhance peri-operative protection of the renal function.
