Successful application of angioembolization and thoracic endovascular aortic repair (TEVAR) in a retrograde type-A acute aortic dissection with polytrauma

Abstract

A 53-year-old man underwent thoracic endovascular aortic repair for persistent false lumen perfusion and limb salvage because of type A aortic dissection, severe lower-limb ischemia, and bleeding (mediastinal hematoma, bilateral lung contusion, liver injury, and splenic injury) caused by blunt trauma. We embolized the left supreme intercostal artery to control active mediastinal hemorrhage. Acute hemorrhage and leg ischemia were well controlled; however, residual blood flow in the false lumen persisted. We performed a Zone 2 thoracic endovascular aortic repair and discharged the patient on day 67. Thoracic endovascular aortic repair is a practical option for treating traumatic type A dissection.
