Presentation
Known trisomy 21 with desaturation during feeding. Request for a water-soluble swallow.
Patient Data

Evidence of mild bronchiolitis with an otherwise unremarkable chest and abdomen in view of known trisomy 21.




There is a persistent and abnormal, oblique, extrinsic impression on the thoracic esophagus at approximately T3/ T4 vertebral level suggestive of an aberrant right subclavian artery.
There is minimal oro-nasopharyngeal reflux.
There is no duodenal atresia.
The water-soluble swallow is otherwise normal.

A screen grab confirms a normal upper abdominal appearance with no duodenal atresia, malrotation, or obstruction.
Case Discussion
A case of a suspected aberrant right subclavian artery in a trisomy 21 patient.
There is an association between trisomy 21 and an aberrant right subclavian artery.
