Blunt multifocal aortic injury with abdominal aortic intimointimal intussusception

Abstract

Blunt abdominal aortic injury is an infrequent occurrence after blunt trauma. The majority of these injuries result from deceleration forces sustained in motor vehicle collisions. Effects of these forces on the thoracic aorta are well described, but associated spinal compression or distraction can also lead to injury of the affixed abdominal aorta. We present a case of multifocal blunt thoracic and abdominal aortic injury with circumferential abdominal aortic dissection, resulting in aortoaortic intussusception associated with a thoracolumbar spinal injury. The unique diagnostic challenge and subsequent successful endovascular management of a rare nonocclusive abdominal aortic intussusception are herein discussed.
