Résumé
We report a case of a 16-year-old boy with Marfan's syndrome who underwent Bentall's procedure on a diagnosis of acute aortic dissection (DeBakey type II). He was readmitted with pyrexia 5 months after the initial operation. Methicillin-resistant <i>Staphylococcus epidermidis</i> (MRSE) was detected by blood culture and transesophageal echocardiography revealed a vegetation adherent to the entry of a remaining false lumen just distal to the distal anastomosis. Although antimicrobial therapy was employed, an arterial embolism developed in the right popliteal artery. CT scan revealed dilatation of the false lumen, and consequently, emergency surgery was performed. The intima of the distal aortic end was partially out of the suture line and the vegetation adhered at that point. Re-replacement of the ascending aorta, omental transposition, and embolectomy of the right femoral artery were performed and resulted in a satisfactory course.
