We studied computed tomographic (CT) appearance of muscle or omental flap transposition procedures in ten patients following clinically diagnosed poststernotomy mediastinitis. Patients were examined either to rule out persistent infection or as part of routine follow-up. An increased amount of soft tissue between open sternal fragments and deformity or apparent “absence” of the utilized muscle were normal postoperative anatomic alterations. Abscess within the flap was diagnosed in one patient who had an abnormal focus of low attenuation in the muscle bundle and scattered air bubbles. An overview with CT correlation of the technical aspects of the reconstructive procedures performed at our institution is provided.
