To summarize the clinical outcomes and experience of redo median sternotomy on proximal aortic repair. Investigate the relationship between first operation and reoperation, reoperation indications, cardiopulmonary bypass strategy, intraoperative technical details, early and mid-term postoperative results.


There were 28 patients underwent 29 times of redo median sternotomy on proximal aorta from April 2017 to December 2019. There were 23 males (79.3%) with an average age of (45.1±12.7) years (26-79 years), 15 Marfan syndrome (15/29, 51.7%) and 3 Behcet's disease (3/29, 10.3%). The primary operation included aortic valve or mitral valve replacement, Bentall procedure, ascending aortic replacement, simultaneous abdominal aortic replacement, Sun's procedure and coronary artery bypass grafting. The indications for reoperation were aortic root aneurysm or coronary artery aneurysm, anastomotic leakage, perivalvular leakage due to inflammatory aortic disease, acute or chronic type A aortic dissection and aortic root abscess, aortic arch aneurysm. The surgical methods were Bentall, Cabrol, wheat, aortic valve sparing root replacement with replantation, anastomotic leakage repair, CABG, total arch replacement + stent elephant trunk implantation (Sun's procedure), ascending aorta to abdominal aorta bypass, abdominal aortic replacement.


One patient (3.4%) died in hospital because of severe postoperative pulmonary complications, consolidation of both lungs, ARDS and hypoxia. Postoperative low cardiac output was occurred in 2 cases (6.9%), 1 case was cured by ECMO, and 1 case died half a year after operation during follow up period. Re-exploration for postoperative hemorrhage was occurred in three cases (10.3%). Renal failure requires dialysis was 3 cases (10.3%), and transient paresis was 1 cases (3.4%), respectively. All of them were recovered before discharge. During the follow-up period, one patient died of multiple organ failure due to low cardiac output, and one patient underwent total thoracoabdominal aortic replacement. One patient underwent Cabrol for aneurysm of the coronary artery after Bentall procedure. One year later, type A dissection occurred again and Sun's procedure was performed through a median sternotomy.


Reoperation of proximal aorta after cardiac and aortic surgery is safe and effective, with good short-term and medium-term results. Comprehensive preoperative evaluation, successful sternotomy, establishment of cardiopulmonary bypass and effective organ protection are the key to successful operation. Patients with aortic diseases, especially Marfan syndrome, are more likely to undergo reoperation. Close follow-up and timely reoperation are necessary to avoid aortic rupture. Sun's procedure is suitable for redo complex arch operation.
