Blunt thoracic aortic injury (BTAI) is predominantly a phenomenon of the 20th century secondary to high-energy deceleration injuries. Prior to the widespread adoption of automobiles, midway through the 20th century, 85% of injuries to the aorta were attributed to penetrating trauma, with 57% caused by gunshots and 25% by stab wounds.1–4 However, BTAI has become more prevalent, with an estimated incidence of 7,500 to 8,000 cases per year in the United States. BTAI is the second most common cause of trauma-related death after head injury and accounts for 15% of all motor vehicle collision (MVC)-related deaths.5 The incidence of thoracic aortic injury among MVC victims is 1.5%.6 Prehospital mortality is 85% secondary to complete aortic transection.7 Approximately 8% of patients survive more than 4 hours, and most of those who survive to reach the hospital have small or partial-thickness tears with pseudoaneurysm formation. Up to 50% of patients who reach the hospital die prior to definitive surgery.8,9 Therefore, expeditious collaborative evaluation by trauma and aortic surgeons at a level I trauma center is necessary to provide appropriate care to these patients who may have multiple life-threatening injuries.
