The Stanford Medicine Children’s Health Fetal and Pregnancy Health Program provides comprehensive evaluation and management of fetal congenital diaphragmatic hernia (CDH).
Congenital diaphragmatic hernia is a very serious condition that occurs when the diaphragm, the muscle that separates the abdomen from the chest, doesn’t develop as it should.
A congenital diaphragmatic hernia is usually diagnosed during a fetal anatomy ultrasound in the second or third trimester. Additional imaging with a fetal echocardiogram and MRI can further delineate any associated structural anomalies and the effect on the developing lungs. An amniocentesis can be performed to determine any associated genetic anomalies.
A congenital diaphragmatic hernia occurs in about 1 in 3,000 pregnancies.
Babies born with a congenital diaphragmatic hernia need surgery, usually after birth, to correct the defect. If the case is severe and the baby is suffering from cardiorespiratory failure, we may need to put the baby on extracorporeal membrane oxygenation (ECMO) for support in order to stabilize the baby before surgery. Because ECMO therapy is complex and has potentially significant complications, it is used only on those babies with few or no alternatives.
Children born with a severe congenital diaphragmatic hernia may be very sick from the moment of delivery, may require ECMO, and may need to be in the NICU for further care for weeks or even months. After discharge, they may need specialized follow-up care with multiple specialties.
