The infant of a mother with hydraminos must be assessed with esophageal atresia.

Hydraminos is excessive amniotic fluid. Any child born to a woman with hydramnios must have esophageal atresia ruled out.

As a result of the fetus's inability to swallow properly due to esophageal atresia, the amniotic fluid level may become unusually high.

When a newborn is born with esophageal atresia (EA), a portion of the esophagus is absent (the tube that connects the mouth to the stomach). The esophagus develops as two distinct, unconnected segments rather than as a tube connecting the mouth and the stomach. Some children have esophageal defects that prevent the ends from being surgically joined. Long-gap EA is what this is called.
