Surgical repair of right aortic arch with aberrant left subclavian artery and left ligamentum arteriosum.
Five cases of right aortic arch with aberrant left subclavian artery and left ligamentum arteriosum, with or without Kommerell's diverticulum, are presented. Either right or left thoracotomy with divesion of the aberrant retroesophageal left subclavian artery can be accomplished with good results. However, a right thoracotomy is recommended in the presence of a large Kommerell diverticulum because such a diverticulum should be excised. The development of a subclavian steal syndrome later in life may be prevented by reimplantation of the divided left subclavian artery into the aorta or the left common carotid artery.
