Congenital Diaphragmatic Hernia, A problem in the Fetus

Prenatal imaging with ultrasound is the standard of careĀ for all pregnancies. Sometimes, we identify abnormalities in the child before birth. One of theseĀ is known as congenital diaphragmatic hernia.Ā When we find this abnormality, we obtain a fetal MRI to understand the anatomy and try to predict outcome.Ā
What isĀ aĀ diaphragmatic hernia? The diaphragm is the structure that separates the chest and the abdomen. If it does not form normally, then the bowel, stomach and liver can slide into the chest.Ā This isĀ what we look for whenĀ diagnosing a congenital diaphragmatic hernia.Ā The important thing is that when these structures move into the chest, then the lungs cannot grow normally; therefore,Ā babies with congenital diaphragmatic hernia have more difficulty breathing because the lungs are small and not normal.Ā
We have identified many babies with this problem. We utilize fetal MRI to calculate how much lung a baby with congenital diaphragmatic hernia has and we can compare it to normal babiesĀ at thisĀ age. With this information, with the specialist at the fetal care center,Ā we can counsel the family and help them decide whether we should intervene in the womb orĀ determineĀ where the baby should be born and with what support. One of the innovative therapies for these babiesĀ whoseĀ lungs are small is to place a balloon in theĀ airway,Ā which creates pressure for the lungs to grow as the fluid present in the lungs cannot escape.Ā Many times we help guide birth with extra support atĀ Cincinnati Childrenās.Ā
With these new therapies, we are improving the outcome for babies with congenital diaphragmatic hernia at Cincinnati Childrenās Medical Center.Ā
