OBJECTIVE: To evaluate the effect of early fetoscopic tracheal occlusion (22-24 weeks) on pulmonary response and neonatal survival in extremely severe isolated CDH. METHODS: Multicenter study involving fetuses with extremely severe CDH (lung-to-head ratio <0.70, liver herniation into the thoracic cavity, no other detectable anomalies). Between August 2010 and December 2011, eight fetuses had early FETO. Data were compared with 9 fetuses that had standard FETO and 10 cases without fetal procedure from January 2006 to July 2010. FETO was performed under maternal epidural anesthesia supplemented with fetal intramuscular anesthesia. Fetal lung size and vascularity were evaluated before and every 2 weeks after FETO by means ultrasounds. Postnatal therapy was equivalent for both treated fetuses and controls. Primary outcome was infant survival to 180 days and second outcome was fetal pulmonary response. RESULTS: Maternal and fetal demographic characteristics, and obstetric complications, were similar in the three groups (p>0.05). The infant survival rate was significantly higher in the early FETO group (57.1%) compared to standard FETO (11.1%) and controls (0%) (p=0.02). Early FETO resulted in a significant improvement in fetal lung size and pulmonary vascularity when compared to standard FETO (p<0.01). CONCLUSIONS: Early FETO may improve infant survival by further increases of lung size and pulmonary vascularity in cases with extremely severe pulmonary hypoplasia in human isolated CDH. This study supports formal testing of the hypothesis with a randomized controlled trial.
