Balloon in the womb: new hope for babies with rare birth defect

This study tests a procedure called FETO for unborn babies with a severe form of left congenital diaphragmatic hernia (CDH), a birth defect where the diaphragm doesn't form properly, causing organs to move into the chest and compress the lungs. The procedure involves placing a tiny balloon in the baby's windpipe while still in the womb to help the lungs grow. The goal is to see if FETO can improve survival and reduce complications compared to standard care. The study includes 21 pregnant women carrying fetuses with severe CDH.
