Simultaneous Norwood And Aortic Uncrossing In Neonate with Aortic Atresia And Right Circumflex Aorta

Right circumflex aorta is a rare vascular ring formed by right aortic arch that follows a retro-esophageal course, crossing midline above the carina level to join a left-sided descending aorta, in addition to left-sided arterial duct / ligamentum arteriosum.1,2 This abnormal vascular anatomy results in compression of the trachea and esophagus by: 1- the ring created by the right aortic arch and left ligamentum arteriosum. 2- the retro-esophageal course of the right aortic arch. Therefore, division of the ligamentum arteriosum alone often fails to relieve the posterior compression caused by the right aortic arch.
