Umbilical artery Doppler sonography is advocated as a method for fetal surveillance. Two cases of fetal distress caused by fetal anemia of non-immune origin are presented. In both cases a normal pulsatility index of the umbilical artery was found. It is emphasized that normal umbilical artery Doppler sonography does not exclude fetal distress.
