This is the first reported case of a traumatic disruption of the thoracic aorta occurring in a patient with a right aortic arch. This unique case emphasizes the need to be aware of the possibility of a traumatic aneurysm even under unusual anatomical circumstances, and the necessity for early aortography. It further emphasizes that aortic fixation by the ligamentum arteriosum is a major factor in the genesis of traumatic injuries of the thoracic aorta, and establishes the benefit of a right lateral thoracotomy in providing excellent surgical exposure.
