Fig 1 (A and B) Three-dimensional computed tomography before first palliation shows a vascular ring consisting of the right aortic arch, an aberrant left subclavian artery, and a left patent ductus arteriosus ligament. (C) White arrow indicates the tracheal stenosis resulting from compression caused by the reconstructed neoaorta.

Fig 2 Surgical technique. (A) Appearance after first palliation. (B) Neo–ascending aorta is transected just above the Damus-Kaye-Stansel (DKS) anastomosis. (C) Craniocaudal view of a transected neoaorta. Posterior wall of the former main pulmonary artery (PA) was cut off into a round shape. (D) Cut edge was sutured longitudinally. (E) Right superior vena cava (SVC) was anastomosed to left PA in an end-to-end fashion using continuous sutures, and right PA and right SVC were anastomosed in an end-to-side fashion using continuous sutures. (∗The broken line in B and C is an incision line.) The Annals of Thoracic Surgery , DOI: ( /j.athoracsur ) Copyright © 2016 The Society of Thoracic Surgeons Terms and Conditions
