Recurrent Pediatric Respiratory Distress From a Challenging Vascular Anomaly: The Uncrossing Operation for Circumflex Aorta

The authors report a case of circumflex aorta causing persistent respiratory distress in a 9-year-old boy who had previously undergone vascular ring division and multiple aortopexies. The uncrossing operation was performed, with symptomatic relief of both posterior and right-sided tracheal compression from the transverse aorta and right aortic arch, respectively.
