Blunt traumatic aortic injury to the brachiocephalic and left carotid arteries.

backgroundBlunt traumatic aortic injury (BTAI) is a life-threatening pathology that most commonly occurs after traffic accidents or a fall from a considerable height. We report a rare case of traumatic double transection which included the brachiocephalic artery (BCA) and left carotid artery (LCA) following a motorcycle accident. CASE PRESENTATION: A 52-year-old man was brought to our emergency room for blunt trauma. Urgent computed tomography (CT) indicated BCA and LCA transection. Two weeks after the BTAI, CT indicated an increase in the size of the BCA pseudoaneurysm, a newly developed LCA pseudoaneurysm, and a spread of hematoma. An emergency partial aortic arch replacement including BCA and LCA reconstruction was performed 17 days after the BTAI. The postoperative course was good, and he was discharged 12 days later.

conclusionsAn open aortic repair appeared to be more suited in the present case because the aortic injury occurred in a branched lesion of the aortic arch. It was thought that complete stent graft coverage of the transection lesion would be difficult. Although coexisting multiple system injuries complicate aortic repair, there was a rapid enlargement of the BCA and LCA pseudoaneurysms. Therefore, strict management is needed even in the case of cervical artery injury.
