Congenital diaphragmatic hernia

Area of Science:

• Pediatric Surgery
• Neonatology
• Developmental Biology

Background:

• Congenital diaphragmatic hernia (CDH) is a critical birth defect involving diaphragm malformation and abdominal organ herniation into the chest.
• This condition leads to pulmonary hypoplasia, pulmonary hypertension, and cardiac dysfunction, significantly increasing mortality and morbidity.
• While the exact cause is unknown, genetic factors contribute in about a third of CDH cases.

Purpose of the Study:

• To provide a comprehensive overview of congenital diaphragmatic hernia (CDH).
• To discuss current diagnostic methods, prenatal and postnatal management strategies, and evolving therapeutic options.
• To highlight long-term morbidities in survivors and emerging research avenues.

Main Methods:

• Diagnosis relies on antenatal ultrasonography, fetal MRI, and echocardiography for risk stratification.
• Prenatal management may involve fetal endoscopic tracheal occlusion to enhance lung growth.
• Postnatal care focuses on cardiopulmonary stabilization, potentially utilizing extracorporeal life support.

Main Results:

• CDH management is evolving with advancements in pulmonary hypertension treatment, ventilation, and surgical techniques.
• Survivors frequently experience long-term multisystem issues, including pulmonary, gastrointestinal, musculoskeletal, and neurodevelopmental problems.
• Emerging research explores small RNA biomarkers and regenerative medicine for fetal lung development.

Conclusions:

• Congenital diaphragmatic hernia presents complex cardiopulmonary challenges requiring multidisciplinary care.
• Continuous evolution of therapeutic strategies and ongoing research are crucial for improving survival and quality of life for CDH patients.
• Focus on regenerative medicine and biomarkers holds promise for future advancements in CDH treatment.
