We present the case of a 41-year-old male trauma patient admitted to the emergency department after being struck in a pedestrian versus a motor vehicle accident. Computed tomography revealed a traumatic transaction of the descending aorta with pseudoaneurysm and an aberrant right subclavian artery with Kommerell diverticulum. Surgical correction was accomplished with bilateral subclavian carotid bypass, with occlusion of both subclavian arteries followed by the placement of endovascular stent grafts to repair the aortic injury.
