ABSTRACT
Objective The aim of this study was to evaluate whether the reoperation is the risk factor for mortality after Sun's procedure(Total aortic arch replacement + frozen elephant trunk) for Stanford type A aortic dissection involving aortic arch.Methods Between February 2009 to February 2012,data from 383 patients who underwent Sun's procedure for Stanford type A aortic dissection involving aortic arch were collected retrospectively.35 patients had history of cardiac surgery.Of these patients,16 patients had underwent Bentall procedure,7 patients ascending aortic replacement,4 patients Wheat surgery,4 patients aortic valve replacement,2 patents Bentall combined with mitral valve replacement or plasty,1 patient bivalve replacement,1 patient atrial septal defect repair,1 patient coronary artery surgery.All the risk factors related to mortality were analyzed by univariate statistical analysis.Significant univariate variables were entered into multiple logistic analysis.Results Total 31 patients died in the hospital and the mortality was 8.07%.Of the 35 patients with history of cardiac surgery,3 patients died and the mortality was 8.33%.Univariate analysis showed that symptom onset before surgery less than 1 week,preoperative limb ischemia,combining with coronary artery surgery and cardiopulmonary bypass time longer than 300 minutes in the operative were risk factors for mortality.After these factors were entered into multiple logistic regression analysis,the result showed that symptom onset before surgery less than 1 week (P =0.038,OR =2.43),cardiopulmonary bypass time longer than 300 minutes(PP <0.001,OR =12.05) were final independent risk factors for mortality.Reoperation was not the independent risk factor for mortality.The intensive care unit and mechanical ventilation length of reoperation group was (2.09 ± 1.89) days and(30.09 ±33.42) hours respectively,while that of primary group was(2.71 ±3.01) days (P =0.25) and(33.86 ±40.98) hours(P =0.61) respectively.The incidence of postoperative bleeding of reoperation group was 3.03%,while that of primary group was 1.88% (P =0.50).Conclusion Reoperation was not the independent risk factor for mortality after Sun's procedure for Stanford type A aortic dissection involving aortic arch and the morbidity was also not higher than primary surgery.For these patients,sun' s procedure should be advocated.
