Blunt traumatic avulsion of an intercostal artery: an unusual case of thoracic aortic injury.
The aortic isthmus is the most commonly injured part of the thoracic aorta in patients who survive blunt deceleration injury to that vessel long enough to reach a hospital. Occasionally, avulsion of the brachiocephalic arteries from the aortic arch is seen. The authors describe an unusual form of intrathoracic vascular injury in which mediastinal hemorrhage occurred secondary to avulsion of an intercostal artery from the descending thoracic aorta as a result of a vertical deceleration injury.
