Double aortic arch with left arch atresia on three-vessel and tracheal view. a (Schematic drawing) and b (Ultrasound images):the left and right aortic arch on both sides of the trachea ran backward and downward. The RARCH connected with the descending aorta and the LARCH was interrupted, and diverticulum-like structure was originated from the descending aorta with its tip pointing to the left. c The same case on long axis of the left aortic arch view: the continuity of the distal LARCH was interrupted after sending out the LCCA and the LSCA in turn, and the left subclavian artery was twisted backward and downward, showing the sign of pulling by the tethered system. d The CTA 3D image of the same case: the RARCH connected with the descending aorta after sending out the right common carotid artery and the right subclavian artery. A diverticulum-like structure was originated from the descending aorta with its tip pointing to the left. The continuity of the LARCH was interrupted after sending out the LCCA and the LSCA in turn, and the LSCA was twisted backward and downward, showing the sign of pulling by the tethered system. Diverticulum: a diverticulum-like structure originated from the descending aorta with its tip pointing to the left; LARCH: left aortic arch; LCCA: left common carotid artery; LSCA: left subclavian artery; RARCH: right aortic arch; T: trachea; the distal left aortic arch was interrupted and the left subclavian artery was twisted backward and downward as shown by↑
