Abstract:
Objective To review the experience of aortic root internal drainage in the operation of type A aortic dissection.Methods This was a prospective and observational study.Clinical data were available from 20 cases of type A aortic dissection patients (A group) from March 2003 to March 2008,and anothcr 36 cases of type A aortic dissection patients (B group) from March 2008 to May 2013.All of patients received the operation of replacement of ascending aortic aneurysm and aortic arch replacement and descending aortic stented elephant trunk implantation in our hospital.The additional inside drainage were made between the aortic root aneurysm sac and right atrial appendage in B group.Perioperative and postoperative data including the operation time,the amount of bleeding,cardiopulmonary bypass time,the amount of red cell transfusion,number of postoperative cases re-operated for hemostasis,total drainage volume in 24 hours,amount of postoperative red blood cell transfusion,number of cases of postoperative pulmonary complications,and postoperative mortality rate were analyzed retrospectively.The data was analyzed using SPSS version10.0 software.The chi-square test was used for constituent ratios,whilest was applied to analysis of differences in above variables betweens two groups.Results There were significant differences in the amount of bleeding during surgery,cardiopulmonary bypass time,the amount of red cell transfusion,rate of postoperative re-operation,total drainage volume in 24 hours,amount of postoperative red blood cell transfusion,number of cases of postoperative pulmonary complications and postoperative mortality between the two groups (x2/t =2.658,2.381,2.265,3.056,6.862,2.896,2.316,7.215,7.668,P =0.012,0.034,0.007,0.016,0.013,0.032,0.008,0.008,respectively).Conclusions The method of aortic root internal drainage in the operation of type A aortic dissection could reduce the amount of bleeding and improve the success rate of operation.
