Supplementary Material for: Fetal pulmonary vascular assessment and its association with p

A prospective cohort study of 49 fetuses with mild or moderate left-sided congenital diaphragmatic hernia evaluated between 2012 and 2018. It measures fetal right pulmonary artery parameters across gestational ages and associates them with postnatal ductus arteriosus flow and clinical outcomes. The dataset was published on figshare under a CC-BY-4.0 license.

Use Cases

• Predict postnatal ductus arteriosus flow abnormalities based on fetal right pulmonary artery diameter measurements.
• Assess the association between prenatal vascular parameters and neonatal outcomes like pulmonary hypertension treatment.
• Evaluate the diagnostic performance of specific RPA diameter cutoffs for predicting abnormal postnatal echocardiography results.

Strengths

• Contains longitudinal measurements of fetal RPA diameter and pulsatility index at three distinct gestational age windows.
• Links prenatal ultrasound data to specific postnatal clinical outcomes, including survival and need for ECMO.
• Provides a statistically derived cutoff value (2.71 mm RPA diameter) with reported sensitivity and specificity.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small at 27.1 KB, indicating limited scope and sample size.
