Clinical Trial Summary

This trial investigates whether prenatal intervention improves survival rate of fetuses with isolated congenital diaphragmatic hernia and severe pulmonary hypoplasia, as compared to expectant management during pregnancy, both followed by standardized postnatal care.

Recruitment information / eligibility

• Status: Completed
• Enrollment: 93
• Est. completion date: December 2020
• Est. primary completion date: March 2020
• Accepts healthy volunteers: No
• Gender: Female
• Age group: 18 Years to 50 Years

Eligibility

Inclusion Criteria:

• Patients aged 18 years or more, who are able to consent
• Singleton pregnancy
• Anatomically and chromosomally normal fetus
• Left sided diaphragmatic hernia
• Gestation at randomization prior to 29 wks plus 5 d (so that occlusion is done at the latest on 29 wks plus 6 d)
• Estimated to have severe pulmonary hypoplasia, defined prenatally as: O/E LHR <25 %, irrespective of the liver position
• Acceptance of randomization and the consequences for the further management during pregnancy and thereafter.
• The patients must undertake the responsibility for either remaining close to, or at the FETO center, or being able to travel swiftly and within acceptable time interval to the FETO center until the balloon is removed.
• Intended postnatal treatment center must subscribe to suggested guidelines for "standardized postnatal treatment".
• Provide written consent to participate in this RCT

Exclusion Criteria:

• Maternal contraindication to fetoscopic surgery or severe medical condition in pregnancy that make fetal intervention risk full
• Technical limitations precluding fetoscopic surgery, such as severe maternal obesity, uterine fibroids or potentially others, not anticipated at the time of writing this protocol.
• Preterm labour, cervix shortened (<15 mm at randomization) or uterine anomaly strongly predisposing to preterm labour, placenta previa
• Patient age less than 18 years
• Psychosocial ineligibility, precluding consent
• Diaphragmatic hernia: right-sided or bilateral, major anomalies, isolated left-sided outside the O/E LHR limits for the inclusion criteria
• Patient refusing randomization or to comply with return to FETO center during the time period the airways are occluded or for elective removal of the balloon

Related Conditions & MeSH terms

Intervention

Procedure:

percutaneous fetoscopy, positioning of endoluminal balloon at 27-30 weeks and whenever possible elective removal at 34 weeks

Other:
• watchful waiting during pregnancy
pregnancy surveillance for fetal wellbeing, development of polyhydramnios and cervical shortening
