Abstract:
We present 4 cases of growth-retarded fetuses with fetal heart rate late decelerations and oligohydramnios. Doppler ultrasound revealed significantly decreased pulsatility index (PI) values of the middle cerebral artery; however, the PI values of the renal artery, femoral artery and umbilical artery were within normal ranges in all fetuses. Relative redistributions in the fetal circulatory system were shown with fetal hypoxemia without acidosis.
