The purpose of this study is to evaluate the safety and efficacy of Fetoscopic Endoluminal Tracheal Occlusion (FETO) in cases of severe Congenital Diaphragmatic Hernia (CDH).
This is an un-blinded, non-randomized, double-arm phase III clinical trial designed to evaluate the safety and efficacy of Fetoscopic Endoluminal Tracheal Occlusion in cases of severe Congenital Diaphragmatic Hernia (CDH) and intrathoracic liver herniation. Patients in the intervention arm will undergo balloon insertion into the fetal trachea between 27 and 30 weeks of gestation. Fetoscopic removal of the balloon occlusion will be performed at 34 weeks gestation.
Inclusion Criteria: * Pregnant person age 18 years or older * Singleton pregnancy * Normal fetal karyotype with confirmation by culture results, Chromosomal Microarray (CMA) with non-pathological variants, Whole Exome Sequencing (WES) or Whole Genome Sequencing (WGS). Results by florescence in situ hybridization (FISH) will be acceptable if the patient is \>26 weeks gestation * Gestational age at enrollment less than 29 weeks 6 days * Intrathoracic liver herniation * Isolated left Congenital Diaphragmatic Hernia (CDH) with Lung to Head Circumference Ratio (LHR) \<30% at enrollment OR isolated…
FETO procedure involves insertion of a balloon into the fetal trachea under IV sedation with local anesthesia or combined spinal-epidural anesthesia. Balloon removal will take place up to 7 weeks after insertion.
