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 countercurrent right brachial angiography. Division of the atretic segment of the left arch and of the ligamentum arteriosum relieved the symptoms.
