Chest injuries have become more common due to the increasing number of motor vehicle accidents. In such cases, it is necessary to exclude serious underlying visceral damage. When the lung is injured, minor lacerations heal spontaneously, while more severe injury produces persistent collapse and leakage of air and blood into the pleural cavity. Aortic arch or thonacic aortic bleeding occurs in nonpenetnating chest trauma and is associated with left-sided hemothorax, pneumothorax, or lung contusion [1-3]. When hemothomax occurs on the might side, injury to pulmonary, cardiac, or thoracic wail structures should be considered. This report describes a patient in whom pulmonary vein laceration was correctly recognized after chest trauma. The literature includes no other such report.
