    Abstract:
    OBJECTIVE: We wanted to establish whether prenatal ultrasonography predicts postnatal outcome in congenital diaphragmatic hernia. STUDY DESIGN: We designed a retrospective multicenter cohort study of 135 patients with congenital diaphragmatic hernia (122 left, 10 right, 2 bilateral, 1 anterior). In isolated left congenital diaphragmatic hernia five potential prenatal prognostic factors were studied: diagnosis at < or = 25 weeks' gestation, polyhydramnios, intrathoracic stomach, small abdomen, and major mediastinal shift. RESULTS: None of the 44 fetuses or infants who had multiple malformations survived. Of the 91 cases of isolated congenital diaphragmatic hernia, there were 82 live births; 76 of these infants had a left congenital diaphragmatic hernia. Of these, 51 (67%) died postnatally. A statistically significant relation was found between mortality and polyhydramnios, intrathoracic stomach, and major mediastinal shift. Mortality increased as a function of the number of these prognostic factors from 20% when none was present to 94% when all three were present. CONCLUSION: In the majority of cases of isolated left congenital diaphragmatic hernia the prognostic value of fetal ultrasonography is too low to alter perinatal management.
