title: Abdominal circumference in fetuses with congenital diaphragmatic hernia: correlation with hernia content and pregnancy outcome.
abstract: To assess the value of abdominal circumference measurements in the second trimester as a predictor of mortality in fetuses with congenital diaphragmatic hernia, 34 fetuses with this condition who had had second trimester ultrasonographic evaluation were analyzed retrospectively for abdominal circumference measurements, content of the hernia, and pregnancy outcome. The abdominal circumference was below the fifth percentile in nine of the 27 fetuses (33%) with an isolated defect and in five of the seven fetuses (71%) with additional anomalies. In fetuses with isolated congenital diaphragmatic hernia, an abdominal circumference measurement below the fifth percentile was associated with the presence of the liver (P < 0.05) but not of the stomach in the chest. In 19 continuing pregnancies with an isolated defect, all five fetuses with an abdominal circumference below the fifth percentile either died prenatally (n = 1), soon after birth (n = 1), or after surgery (n = 3). In contrast, only six of the 14 fetuses (43%) with an abdominal circumference measurement within the normal range died, either soon after birth (n = 2) or after surgery (n = 4) (P < 0.05). We conclude that an abdominal circumference measurement below the fifth percentile in the second trimester appears to be a good predictor of a poor prognosis in fetuses with congenital diaphragmatic hernia.
