Educational Pearls:

  • The number first most common reason for sudden death after a motor vehicle accident is head injury, the second is traumatic aortic rupture. Due to the increased pressure of blood in the aorta, a rupture leads to rapid exsanguination.
  • The most common location for a traumatic aortic rupture is in the descending aorta near the ligamentum arteriosum. This ligament tears the aorta due upon rapid deceleration.
  • The rate of death on the scene of the accident is 80-90%, and even if the person makes it to the hospital with an aortic rupture another 23% die from the condition.
  • It is estimated that about 7500 to 8000 cases of aortic rupture occur per year.
