title: Retrosternal friction-induced late disruption of the anastomotic site between Bentall's valved conduit and an aortic arch graft: report of a case.
abstract: We report a case of late mediastinal false aneurysm originating from disruption of the suture line between synthetic vascular grafts for aortic root and total aortic arch replacements. This aneurysm developed without any infection in a patient with Marfan's syndrome. To our knowledge, this event has never been reported before. The only possible cause of this disruption was that the monofilament suture was broken by continuous friction between the pointed anastomotic line and the sternum since the operation. The treatment options for this unusual event after extended synthetic graft replacement are discussed.
