Blunt Thoracic and Abdominal Aortic Injury in Multiple Trauma: A Case Report.

Background: Blunt abdominal aortic injury (BAAI) is rare among traumatic aortic injuries, and further complications of blunt thoracic aortic injury (BTAI) have never been reported.

Case presentation: A man in his 80s presented to our hospital following a motor vehicle accident. Pan-scan contrast-enhanced CT showed a thoracic aortic isthmus injury (Grade III), an abdominal aortic injury (Grade IV) with extravasation of contrast media at the level of the fourth lumbar vertebra. Endovascular abdominal aortic repair was performed on the same day and a thoracic endovascular aortic repair for BTAI was performed 11 days after admission. The patient had a good postoperative course and was discharged without complications.

Conclusion: This report presented a rare case of BTAI complicated with BAAI. The timing of intervention for aortic injury should be determined based on urgency and other organ damage.
