Late mediastinal shift after repeated aspiration of postpneumonectomy seroma.

Development of a postoperative seroma is a frequent complication after muscle-sparing thoracotomy. We describe an unusual case of late mediastinal shift in a patient in whom our original plan to perform a limited muscle-sparing thoracotomy was abandoned. The procedure was converted to a standard posterolateral incision to perform a pneumonectomy for a large central carcinoid tumor with extrabronchial extension. Fluid that accumulated in her pneumonectomy space presumably shifted into the dissected tissues of her chest wall, and was then drained repeatedly by her local physician in the time interval between 2 weeks and 3 months after surgery.
