title: [Infected false aneurysm due to methicillin-resistant staphylococcus aureus after proximal aortic grafting].
abstract: A 70-year-old man developed meticillin-resistant staphylococcus aureus (MRSA) mediastinitis after prosthetic graft replacement of the ascending aorta. The sternal wound was reexplored and a single-stage procedure of irrigation, debridement, and omental transposition was performed. Ten months after the first operation, he suffered recurrence of pyrexia and the presence of false aneurysm originated from the distal suture line was diagnosed by the chest computed tomography (CT) scan. Re-replacement of the ascending aorta and proximal hemiarch with rifampicin soaked Gelseal was successfully performed. Hypothermic perfusion with circulatory arrest through peripheral cannulation and left ventricular venting via a left anterior thoracotomy was useful to obtain safe reentry in the operation of retrosternal false aneurysm.
