Pulmonary Function following Traumatic Rupture of the Bronchus

摘要: A 33-year-old man developed severe hypoxia following a serious crush injury to the right chest. bronchogram revealed complete obliteration of mainstem bronchus, but on angiography there was persistent perfusion lung associated with calculated shunt in excess 30 percent. Other pulmonary function studies demonstrated wide A-a O2 gradient and restrictive defect. At surgery an unusual anomalous tracheal bronchus lower lobe discovered which also completely occluded. Following pneumonectomy reverted almost normal.
