Prenatal Diagnosis, In Utero Management, and Perinatal Outcomes of Congenital Diaphragmatic Hernia.

Abstract

Congenital diaphragmatic hernia (CDH) is a complex malformation complicating 0.02% to 0.03% of live births. The etiology of CDH is often multifactorial. Sonographic screening can aid in the detection of ~70% of CDH cases. Sonographic measures, that is, lung-to-head ratio, can also be utilized to predict the severity of fetal/neonatal disease and guide fetal eligibility for prenatal interventions, such as the FETO procedure. The FETO procedure has provided improved overall morbidity and mortality among fetuses with severe left-sided CDH, although limited data on its role in the treatment of right-sided CDH and long-term infant and childhood outcomes are limited.
