Fig 1 (A) The 3D CT showed rudimentary RV and the main LV was shown. The great arteries were side-by-side, and the left coronary artery traveled in front of the main pulmonary artery. (B) The trachea is encircled by the vascular ring. (aLSCA = aberrant left subclavian artery; AsAo = ascending aorta; KD = Kommerell’s diverticulum; LCCA = left common carotid artery; LV = left ventricle; MPA = main pulmonary artery; PDA = patent ductus arteriosus; RCCA = right common carotid artery; RSCA = right subclavian artery; RV = right ventricle; T = trachea.)

Fig 2 The schematic drawing of operation. (A) The cannulation site and direction were shown, after dual arterial cannulation (both 8Fr); the distal right arch was transected as the red dotted line and anastomosed to 3.5 mm Gore-Tex graft (arrow). (B) Asterisks show the clamp sites for selective brain perfusion during neo-aortic reconstruction. (C) The intra-operative photo during neo-aorta reconstruction. Neo-aorta reconstruction incorporating AsAo-LCCA, aLSCA, Kommerell’s diverticulum, and the MPA. (D) The 3.5 mm Gore-Tex graft then served as a Blalock-Taussig shunt, while the original right arch became a “neo” right innominate artery and the aberrant left subclavian artery became a “normal” left subclavian artery. (aLSCA = aberrant left subclavian artery; AsAo = ascending aorta; DsAo = descending aorta; KD = Kommerell’s diverticulum; LCCA = left common carotid artery; LPA = left pulmonary artery; LV = left ventricle; MPA = main pulmonary artery; PDA = patent ductus arteriosus; RCCA = right common carotid artery; RPA = right pulmonary artery; RSCA = right subclavian artery; RV = right ventricle; T = trachea.)

Fig 3 From the posterior view, the 3D CT reconstruction image before (A) and 14 days after (B) the operation demonstrates the complete relief of the encircled trachea and the new aorta with left arch. (aLSCA = aberrant left subclavian artery; AsAo = ascending aorta; BT = Blalock-Taussig shunt; DsAo = descending aorta; KD = Kommerell’s diverticulum; LCCA = left common carotid artery; LSCA = left subclavian artery; MPA = main pulmonary artery; RCCA = right common carotid artery; RSCA = right subclavian artery.)
