Aberrant subclavian artery is a rare vascular anomaly that is present from birth. It usually causes no symptoms and is often discovered as an incidental finding (such as through a barium swallow or echocardiogram). Occasionally the anomaly causes swallowing difficulty (dysphagia lusoria).[1][2] Swallowing symptoms in children may present as feeding difficulty and/or recurrent respiratory tract infection.[2] When aberrant subclavian artery causes no symptoms, treatment is not needed. If the anomaly is causing significant symptoms, treatment may involve surgery.[1][2] Children with symptomatic aberrant subclavian artery should be carefully evaluated for additional vascular and heart anomalies.[2]
