[Feto-placental non-immunological anasarca]

Area of Science:

• Perinatology
• Pediatric Cardiology
• Neonatology

Background:

• Fetal hydrops, a condition of excessive fluid accumulation in fetuses, presents significant diagnostic and therapeutic challenges.
• Non-immunological hydrops fetalis (NIHF) encompasses diverse etiologies, including lymphatic abnormalities and idiopathic cases.
• Current management strategies for NIHF have limited success, with high rates of fetal and neonatal mortality.

Observation:

• This study details two clinical cases of fetal hydrops: one attributed to diffuse lymphangiectasis and another of idiopathic origin.
• A comprehensive review of recent literature on the management of non-immunological hydrops was conducted.
• The cases highlight the heterogeneity of fetal hydrops and the need for tailored management approaches.

Findings:

• Diffuse lymphangiectasis represents a specific, treatable cause of fetal hydrops.
• Emerging therapeutic strategies, particularly for fetal chylothorax, show promise for improved outcomes.
• Despite advancements, significant challenges remain, primarily related to the frequent occurrence of lung hypoplasia.

Implications:

• New therapeutic avenues offer potential for improved fetal hydrops management, especially in cases of chylothorax.
• Early diagnosis and intervention are crucial for optimizing outcomes in affected neonates.
• Lung hypoplasia remains a critical factor influencing survival, necessitating further research into preventative or ameliorative strategies.
