Congenital Diaphragmatic Hernia
Basic Information
Definition
Congenital diaphragmatic hernia (CDH) is a diaphragmatic defect resulting from failure of the posterolateral portion of the diaphragm to develop, usually involving the foramen of Bochdalek, resulting in herniation of abdominal contents into the chest cavity. This leads to various degrees of pulmonary hypoplasia.
Epidemiology & Demographics
• There is a 2% recurrence risk, and an autosomal recessive inheritance pattern usually is seen in recurrent cases.
Clinical Presentation
History
• Prenatal: polyhydramnios, lack of stomach bubble, loops of intestine seen in the chest by ultrasound
