Abstract:
Objective To analyze the risk factors of postoperative acute renal injury (AKI) for acute Stanford type A aortic dissection in 137 cases.Methods From January 2010 to December 2011,137 patients with acute Stanford type A aortic dissection were received surgical operations in our hospital.There were 106 males and 31 females with their mean age of(46.8 ± 13.1)years and mean weight of (69.9 ± 18.0) kg.The postoperative acute renal injury diagnosis was according to AKIN diagnosis standard of acute kidney injury network working group in 2005.All patients were received surgical repair with cardiopulmonary bypass,including 120 patients with deep hypothermic circulatory arrest and selective cerebral perfusion.Among them,there were 54 cases with total arch replacement and 66 with right half arch replacement.The postoperative managements were include control the patients' mean arterial blood pressure at 80 to 90 mmHg (1 mmHg =0.133 kPa),supplement the blood volume timely,and correction of hypoxia and hypoproteinemia.The patients were received renal replacement therapy if still oliguria after medical treatments,or their blood creatinine raising continually more than 500 μmol/L.Results A total of 12 patients died in hospitalization with a total in-hospital mortality of 8.74％ (12/137).76 cases had AKI in the first day after operations,including 38 cases (27.7％) with stage Ⅰ and 21 cases (15.3％) with stage Ⅱ and 17 cases (12.4％) with stage Ⅲ.There were 36 patients have acute renal failure (ARF) with morbility of 26.3％ (36/137),and 34 patients among them were received renal replacement therapy.Single factor analysis showed that preoperative creatinine,total arch replacement,cardiopulmonary bypasstime,intraoperative day transfusion of concentrated red cells are risk factors of ARF.Logistic regression was used for multivariate analysis showed that total arch replacement and preoperative creatinine abnormalities are independent risk factors for postoperative AFR.Conclusion Total arch replacement and preoperative creatinine abnormalities were independent risk factors of AFR for acute type A dissection after operation.
