title: Delayed mediastinal infection after ventricular aneurysm resection.
abstract: A patient developing delayed mediastinal infection following ventricular aneurysm resection and double coronary bypass is presented. The source of sepsis was infection of a ventriculotomy incision that had been closed with Teflon-felt buttresses. Diagnosis was established by an increasing opacity on the lateral chest roentgenogram with a stable sternal wound. Treatment was ultimately successful only after removal of the infected Teflon and replacement by simple mattress closure. The need to remove the infected foreign body was clearly established by the initially unsuccessful attempt at simple debridement.
