Abstract

Objective: To determine the association between prenatal ultrasound (US) and magnetic resonance imaging (MRI) characteristics in right congenital diaphragmatic hernia (RCDH) with postnatal outcome.

Study design: CDH Study Group data were reviewed for all RCDH infants (n = 156) born between 2015 and 2019. Prenatal US and MRI lung size measurements were correlated with survival, extracorporeal life support (ECLS), and defect size.

Result: Overall survival was 64.1%. ECLS was required in 40.4%. US and MRI-based prenatal assessment of pulmonary hypoplasia does not predict survival. Prenatal measurement of lung size using either US or MRI correlates with ECLS use. Only MRI-based measures of lung size are associated with defect size.

Conclusion: Image-based prenatal predictors of survival, ECLS, and defect size are of limited value in RCDH. Extrapolation of prenatal survival and morbidity indicators from left to right-sided CDH is not appropriate. There is an urgent need to develop RCDH prenatal prediction models.
