Traumatic bronchial rupture and platypnea-orthodeoxia.

A patient with blunt trauma and traumatic bronchial rupture and lung collapse had prominent symptoms of platypnea-orthodeoxia syndrome. These symptoms were relieved by bronchial repair. The syndrome is rarely seen and is usually associated with a patent foramen ovale or atrial septal defect. The syndrome has not been described previously in association with traumatic bronchial rupture.
