[RIGHT AORTIC ARCH].

Abstract

Introduction: A 66-year-old male developed dysphagia due to external compression of the esophagus caused by an aberrant left subclavian artery, as part of a rare congenital anomaly of a right aortic arch. This represents an incomplete vascular ring-an anatomical variant of the right aortic arch - which is typically asymptomatic but may present with swallowing difficulties in adults, as demonstrated in this case.
