Novel model of Endotracheal Catheter (FETO-balloon) for fetal endoscopic tracheal occlusion in a severe congenital diaphragmatic hernia of fetus (prospective trial)

Objectives: Congenital diaphragmatic hernia frequency is 1: 2000 - 1: 5000 live births worldwide. Mortality in this group in European Union
and the United States is 30 - 50%. The only effective method to prevent severe CDH is fetoscopic endoscopic occlusion (FETO). But it is
associated with a high risk of obstetric complications, premature birth and perinatal mortality of the fetus and newborn. Method: Thirty patients
will participate in this study, divided into an intervention or control group, each containing 15 women. Entry criteria: pregnant age from 18 to 45
years, singleton pregnancy, confirmed diagnosis of severe or extremely severe left, right, or bilateral fetal CDH, normal echocardiography of the
fetus, normal fetal karyotype, the mother must be healthy enough to undergo surgery, signed informed consent of patient. Exclusion criteria involve
contraindications for abdominal surgery, fetoscopic surgery or general anesthesia, latex allergy, allergy or previous adverse reaction to the study
drug specified in this protocol, preterm labor, pre-eclampsia or uterine abnormality, fetal aneuploidy, known structural genomic variants, other
serious fetal abnormalities, or syndromic mutation, suspected primary recognized syndrome with ultrasound or MRI. We will use our developed
novel model of the endotracheal balloon (FETO-balloon), which consists of a distal part (10cm) and a proximal (50cm) with a channel for the
introduction of saline into the cuff of an inflatable balloon. Prevention of RDS will be immediately before the fetoscopic endotracheal occlusion
or/and if there are signs of threatening preterm labor for a period of 24-34 weeks. Time for delivery: 37-38 weeks in both study groups Method
of delivery: cesarean section, Method of Balloon Removal – EXIT. Results: We expect that the rates of survival and morbidity of newborns in
6 weeks, 3 and 6 months, 1 and 2 years will be higher in the intervention group. Pulmonary hypertension, the need for ECMO, the duration of
mechanical ventilation, pulmonary morbidity, gastrointestinal and neurological morbidity, intrauterine infection and the length of hospitalization
of the child will be assessed. Conclusions: It is expected that the use of the proposed method and the noval model of an endotracheal catheter
(FETO-balloon) will avoid re-invasive fetal surgery, fetal damage and minimize the risks of postnatal complications. This assumption is going to
be verified in this study. Patient recruitment is supposed to be completed by the end of 2020.
