congenital diaphragmatic hernia
A birth defect involving incomplete development of the diaphragm, allowing abdominal organs to enter the chest cavity.
Full Definition
Congenital diaphragmatic hernia (CDH) is a serious birth defect characterized by incomplete formation of the diaphragm, creating an opening through which abdominal organs can herniate into the thoracic cavity. This condition can lead to severe respiratory compromise due to pulmonary hypoplasia and persistent pulmonary hypertension. Affected infants require immediate neonatal intensive care, often including ECMO support, and surgical repair once stabilized.
Usage
Usage note: Often abbreviated as CDH; distinguish from acquired diaphragmatic conditions.
