title: CT after reconstructive repair of the sternum and chest wall.
abstract: Acute mediastinitis and sternal infection after sternotomy are potentially devastating complications, but considerable advances in treatment have been made during the past decade. Sternectomy followed by reconstruction with use of either an omental transposition or a muscle flap has markedly decreased mortality and morbidity. After extensive rib resection, various reconstructive repairs, including the use of polytetrafluoroethylene mesh, have proved successful. The authors retrospectively reviewed 27 postoperative computed tomographic (CT) scans obtained in 19 patients. Twelve of these patients had sternal wounds repaired with either omental or muscle flap procedures. Seven patients had chest wall reconstructions with polytetrafluoroethylene patches, muscle transpositions, or both. The authors found no cases of unexpected or unexplained fluid collections on CT scans obtained beyond the 1st month. Any persistent or recurrent collection is suggestive of infection. If clinical and imaging findings are at odds, imaging-directed needle aspiration can help determine whether a fluid collection is infected and in need of further treatment.
