OBJECTIVE: To report on the initial experience in a single Brazilian university clinic of the use of fetoscopic endotracheal occlusion (FETO) to treat severe isolated congenital diaphragmatic hernia (CDH).
METHODS: The inclusion criteria for FETO for this prospective study were isolated CDH and intrathoracic herniation of the liver, as well as the lung area to head circumference ratio (LHR) <1.0. The main variables evaluated were LHR and observed to expected (o/e) LHR before and after FETO, gestational age (GA) at FETO, reversal of tracheal occlusion (TO), and birth and discharge of a living child from the hospital.
RESULTS: Among 8 isolated left-sided CDH cases with normal karyotypes, the median LHR and o/e LHR before FETO were 0.7 (range: 0.6-0.9) and 0.27 (range: 0.22-0.32), respectively. The median LHR and o/e LHR after FETO were 1.2 (range: 0.9-1.8) and 0.45 (0.31-0.67), respectively. The median GA at FETO, reversal of TO and birth were 26.8 (range: 26-29), 32.5 (range: 31.0-34.0) and 37 weeks (range: 35-37), respectively. Neonatal survival at the time of hospital discharge was 50% (4/8).
CONCLUSION: FETO is feasible at our institution and may help to improve postnatal survival of children with severe CDH in developing countries.
