[Injury of pulmonary artery and intrathoracic artery--a surgical case report].

The patient was a 52-year-old man. Tube drainage was performed to the right traumatic hemothorax. Then, 2,000 ml of blood flowed out and bleeding stopped for a time. Four hours later after injury, massive bleeding occurred again. So emergency thoracotomy was performed and we found a laceration in the main pulmonary artery and injury of intrathoracic artery. Pulmonary artery disruption from blunt chest trauma is rare. Further discussion was made by reviewing the related literature.
