Traumatic Thoracic Aortic Dissection with Oral Administration of Antiplatelet Drugs in Multiple Trauma :

A 62-year-old man was transported to the emergency medical center because of blunt chest trauma combined with multiple trauma after a car accident. He complained of severe back pain. Contrast-enhanced computed tomography revealed left hemopneumothorax with multiple left rib fractures, a scapular fracture, lung contusion, liver injury, right renal injury, and acute aortic dissection. Although open surgical repair and endovascular stent grafting were considered, primarily nonoperative management of the thoracic aortic injury under blood pressure control was selected because of the multiple trauma, type B aortic dissection, and oral administration of two antiplatelet drugs. The patient's hemodynamic and respiratory conditions remained stable in the intensive care unit, and the aortic dissection improved. We herein report a rare case of blunt thoracic aortic injury with oral administration of antiplatelet drugs resulting in multiple trauma and acute aortic dissection treated nonoperatively.
