Aberrant subclavian artery: anatomical curiosity or clinical entity.

Dysphagia lusoria, caused by aberrant subclavian artery, is an uncommon cause of dysphagia. When present it is mostly asymptomatic. Barium esophagogram may indicate the presence of this anomaly. Diagnosis needs to be confirmed by CT/MRI prior to any intervention. No treatment is required for asymptomatic patients. If causing significant symptoms, operative management offers definitive treatment. The choice of treatment depends on local expertise, equipment and experience of the surgical team. However, for those who are unfit or refuse operative intervention, there is a role for symptomatic and supportive treatment. Our cases demonstrate three different manifestations of this single entity.
