Traumatic rupture of the pulmonary artery

Traumatic rupture of the main pulmonary artery in a surviving patient is very rare. The case history of a 37-year-old man who sustained blunt chest trauma in a motor vehicle accident is presented. A persistent, bloody right pleural effusion led to the diagnosis of a ruptured right main pulmonary artery, which was surgically repaired using cardiopulmonary bypass. Points of diagnostic interest and therapeutic decision making are discussed.
