A congenital diaphragmatic hernia is a serious birth defect that is typically identified on a routine ultrasound during pregnancy or, less commonly, shortly after your baby is born. If your baby has the condition, he or she will need surgery to repair the defect soon after delivery. Caring for your baby -- during delivery, after birth, through surgery, and as he or she grows -- is our pediatric experts’ main concern. We have the experience and resources to ensure your baby has the best possible outcome.
