Objectives. To assess the effectiveness of the use of prenatal ultrasound indexes in congenital diaphragmatic
hernia of the fetus to determine the postnatal prognosis.
Materials. The analysis of 95 observations of left-sided congenital diaphragmatic hernia of the fetus was
carried out. In the prenatal period, the composition of organs displaced into the pleural cavity was determined,
the heart compression index (HCI), O/E LHR according to Jani and DeKoninck, and QLI were calculated.
Results. Survival rate of newborns was 57.9%, mortality rate was 42.1%. The newborns were divided into
two groups depending on the outcome of the disease. Group I — surviving newborns (n = 55), group II —
deceased patients (n = 40). In the analyzed groups, there were no statistical differences in the timing of delivery,
birth weight of newborns, the severity of asphyxia after birth and the type of hernia. In group I, the intestinal
loops and stomach were significantly more often identified in the pleural cavity in isolation, less often the liver.
HCI corresponded to 1.3, Jani O/E LHR 45.7%, DeKoninck O/E LHR 38.7%, QLI 0.7. In group
II, concomitant malformations, polyhydramnios and displacement of the liver into the pleural cavity were
significantly more frequent. HCI was 1.5, Jani O/E LHR 38.6%, DeKoninck O/E LHR 32.0%, QLI 0.6.
Conclusions. In predicting the outcome of the disease for a newborn, the most effective is a comprehensive
assessment of the location of the liver, the heart compression index and the index of lung hypoplasia (O/E
LHR according to Jani). The diagnostic accuracy of the method is 80%, the sensitivity is 74.4%, and
the specificity is 83.3%.
