“…The term, “circumflex aorta” is used for congenital aortic arch anomalies with high retroesophageal arch segment above the carina with both the proximal descending aorta and ligamentum arteriosum on the opposite side forming a vascular ring, while the distal descending aorta may or may not cross back to the other side of the spine. 5 A Kommerell diverticulum is invariably present. A left-sided ductus arteriosus or ligament arises from the main pulmonary artery and connects to the descending aorta; thus, completing a vascular ring.…”

Circumflex aorta is described as a retroesophageal aortic arch, with opposite-sided descending aorta forming a true vascular ring with ligamentum arteriosum. We report two cases of right-sided circumflex aorta with varied clinical presentation. Computed tomography diagnosed this vascular ring anomaly. The patients were managed with the aortic uncrossing procedure as a primary surgical strategy. Preoperative diagnosis and thorough planning were essential for the successful outcome. The patients did not have any residual symptoms of tracheal and esophageal compression on follow up.
