Esophageal foreign bodies in children with vascular ring or aberrant right subclavian artery: coincidence or causation?

This is the report of 4 children, 2 with a vascular ring and 2 with an aberrant right subclavian artery, who presented with an esophageal foreign body in the proximal esophagus above the level of the vascular anomaly. A deep erosion of the esophagus at the site of the foreign body was demonstrated in 2 patients.
