The Aortic Uncrossing Procedure in a Two-Year Old Child with a Circumflex Left Aortic Arch and a Right Sided Arterial Duct: Technical Details with 1-Year Follow-Up

Abstract

Circumflex aortic arch is a rare vascular ring, with the circumflex right aortic arch much more common than a left aortic arch. The aortic uncrossing procedure has become the surgical intervention of choice for this anomaly. In younger children, some surgeons prefer a simpler procedure, such as resection of the descending aortic diverticulum or ligation and division of the arterial duct, with the uncrossing procedure reserved for those with residual airway or esophageal compression. We report an aortic uncrossing procedure in a 2-year-old girl with the very rare left circumflex aortic arch who remained symptom-free at 1 year follow-up.
