Disruption of the thoracic aorta due to blunt chest trauma is often fatal and should generally be treated surgically as soon as possible. However, cases of disruption of the thoracic aorta due to blunt chest trauma are often complicated by damage to vital organs, making treatment difficult. Our policy is to treat other organs before treating the thoracic aorta in 1) cases in which fracture of the pelvic bone or bleeding from abdominal cavity organs is causing shock and 2) cases of severe cerebral contusion or intracranial hemorrhage that require emergency surgical treatment. The use of a stent for treatment of acute-stage cases should be considered prudently.
