Blunt aortic injury is the most lethal injury of the thorax, of which aortic transection is the second leading cause of death. Pseudoaneurysm formation is seen in patients who survive the injury and arrive to the emergency department with small or partial-thickness tears of the aorta. In general, the proximal descending aorta is most commonly afflicted due to the relatively mobile aortic arch moving against the fixed descending aorta. There are several factors associated with a high risk of aortic injury including high-speed motor vehicle collision (MVC) accidents, unrestrained drivers and passengers, extensive impact/collision and abrupt deceleration of motor vehicles. In this case study, a 28-year-old male patient with a thoracic aorta injury is presented. Diagnostic findings consistent with transection and/or dissection and a review of his surgical management are also discussed.
