The objective of this study was to assess whether the laterality of CDH was a prognostic factor for neonatal survival.


This was a cohort study using the French national database of the Reference Center for Diaphragmatic Hernias. The principal endpoint was survival after hospitalization in intensive care. We made a comparative study between right CDH and left CDH by univariate and multivariate analysis. Terminations and stillbirths were excluded from analyses of neonatal outcomes.


A total of 506 CDH were include with 67 (13%) right CDH and 439 left CDH (87%). Rate of survival was 49% for right CDH and 74% for left CDH (P < 0.01). Multivariate analysis showed two factors significantly associated with mortality: thoracic herniation of liver (OR 2.27; IC 95% [1.07-4.76]; P = 0,03) and lung-to-head-ratio over under expected (OR 2.99; IC 95% [1.41-6.36]; P < 0.01). Side of CDH was not significantly associated with mortality (OR 1.87; IC 95% [0.61-5.51], P = 0.26).


Rate of right CDH mortality is more important than left CDH. Nevertheless after adjusting for lung-to-head-ratio and thoracic herniation of liver, right CDH does not have a higher risk of mortality than left CDH. This article is protected by copyright. All rights reserved.
