Endovascular repair of traumatic innominate artery injury: case report

Traumatic injury to the innominate artery (IA) is an uncommon vascular condition with a prehospital mortality up to 70%. It may result from high-speed blunt chest trauma. We present a 22-year-old male motorcyclist who was struck by a car. The patient sustained multiple injuries and the initial assessment revealed a hemopericardium and a widened mediastinum. Following stabilization, whole-body imaging showed an intimal flap of the IA with contained contrast extravasation, and a lung laceration. The patient underwent endovascular stent grafting of the IA pseudoaneurysm via femoral artery access. Subsequently, he required maxillofacial and orthopedic procedures. At the time of rehabilitation, he was ambulating independently with minimal assistance and expressed satisfaction with his return to routine. Blunt IA injury is a rare but life-threatening vascular trauma that necessitates rapid diagnosis and tailored management. This case highlights that endovascular stent grafting may serve as a safe, minimally invasive alternative to conventional open surgical repair in appropriately selected patients.
