Blunt chest trauma with tracheobronchial rupture.

The unusual complex of physiological problems associated with rupture of the tracheobronchial tree complicating blunt chest trauma is discussed. The mechanics of injury leading to rupture are abrupt compression of the chest with consequent fixation of the cervical trachea where it enters the mediastinum, separation of the lungs, and fracture of the bronchus over the vertebral bodies. Treatment by aspiration thoracentesis, tracheotomy, and thoracotomy with primary repair as well as expectant therapy are discussed. Two cases, one treated expectantly and one treated by thoracotomy, both with complete recovery, are presented.
