The Analysis Of Risk Factors Of Mortality Of Type A Aortic Dissection After Operation

Objective: To assess the risk factors of the in-hospital mortality of acute type Aaortic dissection after operation.and improve the prevention and treatment of the validity andrelevance.Methods: From January2002to december2012,102patients，76males and26females，with acute typeA aortic dissection operated on were enrolled.The averageage of patients was (49.46±11.04)years old.The patients,demographics,history,clinicalfeatures,a-nd some laboratory examinations were reviewed.Univariate and multivariate analysisfollowed by logistic regression analysis were carried out to identify the predictors ofinhospital mortality.Result:The in-hospital rate was17.6%,The results of univariateand multivariate analyses as follows: Univariate analysis showed thatCardiopulmonary bypass (CPB) time,aortic clamp time, preoperative renalinsufficiency, and D dimer levels and postoperative mortality, using stepwise logisticregression analysis showed cardiopulmonary bypass (CPB) time, preoperative renalinsufficiency, and preoperative D-dimer level is an independent risk factor for deathfor patients. Conclusion: Acute Stanford type A aortic dissection surgery after deathis the result of multiple factors, including cardiopulmonary bypass (CPB) time,preoperative renal insufficiency, D-dimer levels in acute Stanford type A aorticdissection patients after surgery deathan independent risk factor.
