Abstract：Objective To summarize the re-operation experience of dissection of aorta after aortic valve replacement.Methods Twelve cases of dissect:on of arota after aortic valve replacement(AVR) were collected from June 2009 to November 2010.Among the 12 cases,8 cases were ascending aortic dissection,2 cases were ascending and arch aortic dissection and 2 cases were ascending,arch and descending aortic dissection.8 patients were treated with operation on cardiopulmonary bypass(CPB).Results Primary diseases of 10 cases were aortic insufficiency and 2 cases were aortic stenosis.1 case died before reoperation,3 cases refused to perform reoperation and 1 died of multiple organ failure after operation.The false lumen closed after 3 months.No new dissection occurred.Conclusion Aortic dissection after AVR occurred in patients whose primary disease is AI with ascending aortic dilatation,which is possibly related to the first procedure and improp.er treatment of ascending aorta,however the selection of reoperation mode is also important.
