Fetal endoskopisk trakeal ocklusion (FETO) prövning för medfödd diafragmabråck (CDH) (FETO)
Fetal endoskopisk trakeal ocklusionsförsök för medfödd diafragmabråck (CDH)
This is a single site pilot trial to assess the feasibility and safety of treating severe CDH with Fetal Endoscopic Tracheal Occlusion with the Goldballoon Detachable Balloon (GOLDBAL2) along with the Delivery Microcatheter (BALTACCI-BDPE100) at Michigan Medicine. The study will enroll pregnant women that meet study criteria. Participants will have placement of FETO between gestational age at 27 weeks plus 0 days and 29 weeks 6 days. The timing for removal of FETO will ideally be between 34 weeks 0 days and 34 weeks and 6 days but ultimately decided by the Fetal Diagnosis and Treatment Center at Michigan Medicine.
This study requires that study participants live within 30 miles of the Von Voigtlander Women's Hospital and C.S. Mott Children's Hospital in order to maintain weekly follow up appointments while the balloon is in place and up to delivery. Additionally, there are lifestyle considerations where participants would be unable to carry on normal daily activities including exercise and sexual intercourse, not be able to work the remainder of the pregnancy, as well as have a support person that is available to stay with such as a spouse, friend, partner, parent.

- Willing to comply with restrictions of daily living including inability to exercise, have intercourse, or return to work.
Exclusion Criteria:
- Multi-fetal pregnancy
- History of latex allergy
- History of preterm labor or incompetent cervix (requiring cerclage), short cervix (≤20mm), or uterine anomaly predisposing to preterm labor
- Bilateral CDH, unilateral CDH with o/e LHR > 25%, or unilateral CDH with o/e LHR <25% but liver completely down in abdomen
- Additional fetal or genetic abnormalities that would impact care after delivery or be known to have an impact on outcome

Experimentell: FETO with GOLDBAL2
A balloon will be placed in the airway of the fetus during the FETO procedure. |
This will take place between gestation of 27w0d - 29w6d. The balloon will be removed at approximately 34 weeks gestation. |

Number of Participants With Successful Placement of the Goldballoon Detachable Balloon (GOLDBAL2) at Gestational Age 27 Weeks Zero Days (27w0d) to 29 Weeks and 6 Days (29w6d) Gestation.
Tidsram: Between 27 weeks 0 days and 29 week 6 days of gestation, within 1 week of enrollment
|
Success will be defined as completion with direct visual placement above the carina and confirmation on ultrasound done during the procedure. |
Between 27 weeks 0 days and 29 week 6 days of gestation, within 1 week of enrollment

|
Number of Participants With Successful Retrieval of the GOLDBAL2
Tidsram: Removal prior to delivery approximately 34 weeks of gestation (up to approximately 8 weeks post enrollment) or at delivery on placental bypass (up to approximately 14 weeks post enrollment)
|
This will ideally occur around the 34th week of gestation and have the balloon removed prior to delivery. Alternatively, it could occur on placental bypass. |
Removal prior to delivery approximately 34 weeks of gestation (up to approximately 8 weeks post enrollment) or at delivery on placental bypass (up to approximately 14 weeks post enrollment)

Change in Observed to Expected Total Fetal Lung Volume (o/e TFLV) on Prenatal Magnetic Resonance Imaging (MRI)
Tidsram: baseline (prior to balloon placement), approximately 2 weeks after balloon retrieval (approximately 11 weeks post enrollment)
|
Fetal MRI done prior to balloon placement and again done at approximately 2 weeks of balloon retrieval. Observed to expected total fetal lung volume (o/e TFLV) is the percentage of lung volume a fetus has compared to the expected lung volume for a fetus at the same gestational age. It is calculated by dividing the observed TFLV by the expected TFLV and multiplying by 100 to get a percent. This outcome measure is the median change in o/e TFLV between the MRIs. |

|
Change in Fetal Lung Growth
Tidsram: baseline (before balloon placement), immediately prior to balloon removal (up to approximately 14 weeks post enrollment)
|
Fetal ultrasounds will be done weekly while the balloon is in place. Fetal lung growth will be calculated as the difference between the observed to expected Lung to Head Ratio (o/e LHR) pre-balloon placement and the o/e LHR immediately prior to balloon removal. O/e LHR uses the area of the lung opposite of the diaphragmatic hernia divided by head circumference to get a lung to head ratio. The observed to expected lung to head ratio is the lung to head ratio divided by the expected lung to head ratio at that gestational age multiplied by 100 to get a percent. This outcome measure describes the change in o/e LHR. |
