[Torsion after left lower lobectomy and cerebral infarction following the re-exploratory thoracotomy: a case report].

A 38-year-old man had a left lower lobectomy for pulmonary carcinoid. Following the operation, torsion of the left residual upper lobe occurred. Re-explosive thoracotomy was performed on the second postoperative day. The left upper lobe showed a clockwise 180-degree rotation. Pneumonectomy was not done. After the re-thoracotomy, the patient developed right hemiplegia. Head CT showed a cerebral infarction due to the thrombus of pulmonary vein that was released after the repair of the torsion.
