Anterior approach to traumatic mid aortic arch transection.

The majority of nonpenetrating traumatic injuries to the thoracic aorta are fatal. Survivors of aortic transection tend to have injuries occurring at the isthmus. We report a rare, blunt traumatic complete transection of the mid aortic arch between the innominate and left common carotid arteries diagnosed by multidetector computed tomography of the chest. The repair was approached anteriorly and required aortic arch replacement.
