A 77-year-old man developed deep sternal wound infection with Enterobacter cloacae 4 days after total aortic arch replacement for distal aortic arch aneurysm. Reexploration and open drainage of the mediastinum was carried out for 4 days, and the vacuum-assisted closure system was applied and continued for 10 days. During the treatment, granulation formation and neovascularization was apparently enhanced which lead us to perform omental transfer and chest closure on the 18th postoperative day. The patient has been free from recurrent sign of mediastinal infection or graft infection for the 19 months of the follow-up period.
