Fetal balloon surgery aims to save babies with rare birth defect

This study tests a fetal surgery called FETO for severe congenital diaphragmatic hernia (CDH), a condition where a hole in the diaphragm allows organs to crowd the lungs. Researchers will place a tiny balloon in the fetal windpipe to encourage lung growth, then remove it before birth. The trial includes 10 pregnant women and focuses on whether the procedure is safe and feasible.
