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