Hernia, DIaphragmatic, Congenital

This registry study aims to confirm that FETO increases neonatal survival to discharge and reduces long-term morbidity in fetuses with isolated left CDH and o/e LHR \< 30%, or isolated right CDH and o/e LHR ≤ 45%, compared to those receiving standard care. This prospective registry plans to enroll 80 pregnant women (40 treatment/40 control) with fetuses diagnosed with isolated CDH, and the children will be followed for up to 24 months.

This is a single site pilot trial to study the feasibility of Fetoscopic Endoluminal Tracheal Occlusion (FETO) therapy in the most severe group of fetuses with congenital diaphragmatic hernia (CDH) at Midwest Fetal Care Center, a collaboration between Allina Health and Children's Minnesota. This procedure aims to increase fetal lung volume before birth and improve survival after birth. This study will enroll 10 pregnant people and their baby who meet study criteria.
