Ruptured thoracic aorta due to blunt trauma.

Thirty-six ruptured thoracic aortas have been diagnosed in a total of 3,500 patients seen at the Maryland Institute for Emergency Medicine in the past 5 years. To our knowledge, no ruptured thoracic aortas have gone undetected. A new method of performing portable chest radiography has been developed which we feel clarifies the diagnosis of mediastinal hematomas and which allows us to determine which patients will undergo aortography. The reported survival rate of 75% is felt to be due to the rapidity with which these patients are brought to the hospital and use of a carefully planned protocol which permits early diagnosis and treatment. These results are due to the combined efforts of the Maryland State Police Helicopter System, the traumatologists, anesthesiologists, nurses, paramedics, radiologists, and thoracic surgeons working together as a completely integrated team.
