CDH
Also written as: CDH — congenital diaphragmatic hernia
Congenital diaphragmatic hernia; developmental defect allowing abdominal organs to herniate into the chest.
Full Definition
A developmental anomaly characterized by incomplete formation of the diaphragm, most commonly involving the posterolateral aspect (Bochdalek hernia). The defect allows herniation of abdominal contents into the thoracic cavity, leading to pulmonary hypoplasia and persistent pulmonary hypertension. The condition carries significant morbidity and mortality due to respiratory compromise. Management involves initial stabilization with mechanical ventilation, surgical repair once the patient is stabilized, and long-term management of pulmonary complications. Severe cases may require ECMO support and innovative techniques like fetal intervention.
Usage
Usage note: Define on first use. Specify location (left vs right) and whether primary repair or patch closure was required.
