Congenital Diaphragmatic Hernias

Congenital diaphragmatic hernia (CDH) is a birth anomaly where there is a defect in the diaphragm. Bochdalek hernia, which involves a posterolateral defect with herniation of the abdominal organs into the thoracic cavity, and a varying degree of lung hypoplasia, accounts for more than 95% of CDH. Non posterolateral hernias are classified into three groups: (a) retrosternal or parasternal (Morgagni-Larrey); (b) other anterior hernias that extend into the anterior portion of the central tendon and are associated with other anomalies; and (c) central hernias, where the defect primarily involves the non-muscular central tendinous part of the diaphragm (1).
