title: Repair of right aortic arch with aberrant left subclavian artery and left ligamentum arteriosum.
abstract: A case of right aortic arch with an aberrant left subclavian artery arising from a Kommerell's diverticulum of the descending thoracic aorta with a left ligamentum arteriosum completing a vascular ring about the trachea and esophagus is presented. A posterolateral left thoracotomy alone is sufficient to provide an excellent exposure for the division of the ligamentum arteriosum and the resection of the Kommerell's diverticulum. Furthermore, the development of a subclavian steal syndrome is prevented by the reimplantation of the divided left subclavian artery into the left common carotid artery through this same incision.
