title: Postpneumonectomy syndrome.
abstract: Postpneumonectomy syndrome is a rare postoperative complication whereby mediastinal shifting toward the pneumonectomy space results in bronchial compression between the pulmonary artery, aorta, and vertebral column. This syndrome is more common after right pneumonectomy; other risk factors include young age and female sex. Imaging studies consistently reveal massive mediastinal shifting and document airway compromise. Bronchoscopy and flow-volume loops are helpful in confirming the diagnosis. Other causes of dyspnea, including cancer recurrence, should be excluded. Definitive treatment involves surgical repositioning of the mediastinum in the midline, as well as insertion of a saline-filled silicone prosthesis into the pneumonectomy space in order to prevent recurrence.
