congenital diaphragmatic hernia
Also written as: CDH — congenital diaphragmatic hernia
Birth defect where abdominal organs herniate into the chest through a diaphragmatic defect.
Full Definition
A congenital malformation characterized by a defect in the diaphragm that allows abdominal organs to herniate into the thoracic cavity, most commonly on the left side. This condition can cause severe pulmonary hypoplasia and persistent pulmonary hypertension due to compression of developing lung tissue. Prenatal diagnosis is made by ultrasound showing abdominal organs in the chest cavity and may be associated with polyhydramnios. Prognosis depends on the degree of lung hypoplasia, presence of liver herniation, and associated anomalies. Management includes specialized delivery planning and immediate postnatal respiratory support.
Usage
Usage note: Specify the side (left or right) and whether liver herniation is present, as these affect prognosis significantly.
