The prognosis for children with congenital diaphragmatic hernia varies depending on the type and severity of the hernia. In general, children with no complications or severe malformations have good surgical outcomes and a high survival rate; those with complications such as pulmonary dysplasia, persistent pulmonary hypertension, ischaemic necrosis of the herniated abdominal organs, fetal chromosomal abnormalities or other severe malformations have a relatively low survival rate.
In recent years, neonatal treatment techniques such as ECMO are being developed and the survival rate of children with congenital diaphragmatic hernia has increased significantly.
