Management of a traumatic ruptured aorta in the pediatric population is quite challenging. Options vary, with each having its own morbidity, and include open repair, endovascular stent grafts, and/or anti-impulse therapy. Although endovascular stenting is an emerging management modality in traumatic aortic injury in adults, open repair is still the gold standard in the pediatric population.In this case, we reported the survival of a three-year-old boy who underwent successful surgical repair with a Dacron graft and anastomosis after an acute traumatic thoracic aortic pseudoaneurysm with mediastinal hematoma.
