INTRODUCTION
Postoperative thoracic aortic graft infection (TAGI) is a serious and potentially fatal complication. There is no definitive treatment protocol for TAGI. The classical approach is to replace the infected graft by a biological graft such as homograft or xenograft.1 However, surgical management is challenging, and graft replacement after TAGI has a high mortality rate .2,3 Moreover, difficulties in finding appropriate biograft, high cost, and degeneration of the biografts are known disadvantages of this approach. On the other hand, the morbidity and mortality of a second operation will be high especially when the co-morbid factors of such patients are considered. Treatment of TAGI without replacement of the graft is an approach that has been discussed in recent years and a limited number of cases have been reported.2,3,4,6-8 In this report, we present successful treatment of a case with mediastinitis and aortic graft infection after Stanford type A aortic dissection surgery who was treated with vacuum-assisted closure (VAC) therapy followed by omental flap coverage without graft replacement.
