Congenital diaphragmatic hernia

Area of Science:

• Pediatric Surgery
• Neonatology
• Developmental Biology

Background:

• Congenital diaphragmatic hernia (CDH) is a rare congenital anomaly characterized by diaphragm defects, leading to abdominal organs entering the chest.
• This condition causes pulmonary hypoplasia and hypertension, significantly impacting infant survival and development.
• Recent progress in prenatal diagnosis and understanding prognostic factors guides fetal and postnatal management strategies.

Purpose of the Study:

• To provide a comprehensive review of congenital diaphragmatic hernia (CDH).
• To focus on the pathophysiology, diagnostic advancements, fetal therapies, and postnatal management of CDH.
• To highlight improvements in infant outcomes through refined treatment protocols.

Main Methods:

• Review of current literature on congenital diaphragmatic hernia (CDH).
• Analysis of advances in prenatal diagnosis and prognostic factor identification.
• Evaluation of established and emerging fetal and postnatal therapeutic approaches.

Main Results:

• Prenatal diagnosis and prognostic factor identification have refined fetal therapy approaches for CDH.
• Protocolized postnatal care, including lung-protective ventilation and pulmonary hypertension management, has improved infant outcomes.
• Surgical repair is often deferred until the infant's pulmonary status is stable, optimizing surgical timing.

Conclusions:

• Congenital diaphragmatic hernia (CDH) management has evolved significantly with improved prenatal and postnatal strategies.
• Early and aggressive management of pulmonary hypertension and lung-protective ventilation are critical for better outcomes.
• A multidisciplinary approach integrating fetal interventions and optimized postnatal care is essential for improving survival rates in CDH patients.
