Clinical Trial Summary

Tracheal occlusion IDE approved by FDA for congenital diaphragmatic hernia fetuses.

Description:

Fetuses with congenital diaphragmatic hernia with liver-up, and an observed to expected lung-to-head ratio of <25%, LHR <1, or a moderate category with o/e LHR <30%, singleton pregnancy, no known other anomalies, gestational age < 29 weeks 6 days (severe), gestational age < 31 weeks 6 days (moderate), no maternal disease, maternal age > 18 years old…. meet criteria to be offered fetal tracheal occlusion. We want to test feasibility and efficacy in our center.
