Type C double aortic arch. Double aortic arch with aberrant left subclavian artery.
Four infants with type C double aortic arch (double aortic arch with aberrant left subclavian artery) are discussed. The diagnosis was based on symptoms and signs of tracheoesophageal compression with a bilateral impression in the frontal plane of the esophagogram, as well as on early visualization of the aberrant left subclavian artery during counter-current right brachial angiography. Division of the atretic segment of the left arch and of the ligamentum arteriosum relieved the symptoms.
