Thoracic Endovascular Aortic Repair (TEVAR) in traumatic high-velocity blunt injury to thoracic aorta.

Blunt trauma to the thoracic aorta occurs typically in a highvelocity or high-impact motor vehicle accident when there is a combination of sudden deceleration and shearing at the relatively immobile aortic isthmus; the area distal to the left subclavian artery and proximal to the third inter-costal artery, representing the junction between the relatively mobile aortic arch and the fixed descending aorta. Hence, the isthmus is the most common location for rupture (50% to 70%), followed by the ascending aorta or aortic arch (18%) and the distal thoracic aorta (14%).
