Fetal Risk Stratification and Outcomes in Children with Prenatally Diagnosed Lung Malformations
Topic overview
Multi-institutional study of 344 prenatally diagnosed congenital lung malformations identifies CVR thresholds for risk stratification: initial CVR ≤1.4 predicts low hydrops risk, maximum CVR <0.9 correlates with asymptomatic disease at birth. Findings enable standardized prenatal counseling and delivery planning for this heterogeneous condition.
Key takeaways
- Initial CVR ≤1.4 identifies fetuses at very low risk for hydrops in prenatally diagnosed congenital lung malformations.
- Maximum CVR <0.9 is associated with asymptomatic disease at birth, aiding delivery planning and parental counseling.
- 21.8% of neonates with prenatal CLM diagnosis had respiratory symptoms at birth; 10% required neonatal lung resection.
- Prenatal surgical intervention for CLM remains uncommon (1.7%); maternal steroids used in 5.5% of hydrops cases.
- CVR measurements significantly predict perinatal outcomes including respiratory distress, oxygen need, and ventilator use.
