Antenatal ultrasound

• CDH can be diagnosed in the 24th week.
• In addition to the hernia, ultrasound can show polyhydramnios and absence of the gastric air bubble
• Left sided CDH is far more common than right sided CDH, while bilateral CDH is rare.
• The presence of liver herniation is associated with worse prognosis and survival.
• The estimation of lung area to head circumference ratio can give an idea about the prognosis (especially if there is no liver herniation). The lower the ratio, the worse the prognosis.
