Aortic Uncrossing for Circumflex Aorta

Abstract

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.
