A to Z: Atresia, Esophageal

Atresia (ah-TREE-zhah) is a condition in which a baby is born with a missing or closed valve or tube somewhere in his or her body.

Esophageal atresia is a defect of the digestive tract in which a baby is born with an esophagus that is not properly developed. It is treated surgically.

More to Know

Air, blood, bodily fluids, and waste products travel throughout the body in a system of vessels, tubes, and chambers that are often separated by valves. When a child is born with atresia, it means that a valve is missing or a tube is closed off. This interrupts the normal flow of blood, fluid, waste, or air, which can lead to a number of complications.

Most kinds of atresia are serious and can be fatal if they go untreated. Treatment usually involves surgery while the child is still an infant.

Atresia can affect many body parts, including the nose, ears, organs, digestive tract, and heart. The types of atresia are named for the body parts they affect:

Keep in Mind

Most kinds of atresia can be treated successfully with surgery; some cases may require more than one operation.
