Late reoperations after repaired acute type A aortic dissection

摘要: Objective Late complications can develop in patients after surgery for aortic type A dissection, mandating redo on the ascending aorta and arch. Methods From 2006 to 2010, 23 (aged 41–69 years) who had late related previous acute dissection underwent surgery. Initial included replacement all cases. Results The main indications reoperation were progressive enlargement of false lumen arch or descending suture line dehiscence 10 each. All with aneurysm formation nonresected segments persistent within since initial Suture led a localized hematoma most Three presented graft infection extensive perigraft hematoma. average time interval from repair procedure was 71 ± 56 months. Exchange formerly implanted Dacron frequently used surgical procedure. Implantation valved conduit deemed necessary 4 cases, isolated valve 2 hybrid stent 6 patients. survived surgery, 1 patient died postoperative low output cardiac failure hospital. Only major stroke noted. Conclusions Complex reoperations repaired be performed safely. concern reoperative risk should not dictate operative strategy during dissection.
