Vascular Ring Anomaly

Vascular ring anomaly constricts the esophagus. This is a situation in which the fetal blood vessels are still present when they should not be. The most common form of this is a persistent right aortic arch, but there are other possible ring anomalies. The vessel passes over the esophagus and captures it between the persistent aortic arch and other structures, constricting it. This can be cured surgically if many cases. In some cases, the esophageal motility is permanent impaired and it is necessary to feed liquid or semi-solid meals from a standing position for life.
