Doppler examinations of the umbilical artery, both uterine arteries, and the fetal middle cerebral artery were performed in the third trimester in 18 patients with pregnancy induced hypertension, 52 patients with preeclampsia, and 32 patients with HELLP syndrome and the results were correlated with the parameters fetal outcome. For 74% of the patients this was the first pregnancy, in 93% of the cases a cesarean section was necessary; 66% of the newborn babies were dystrophic and 90% of them were born prematurely. The blood flow in one uterine artery was restricted in 95% of all 102 pregnant women, only 5% did not show any pathological findings. A pathological blood flow was observed on Doppler sonography in the umbilical artery in 70% of the group and 39% showed a pathologically increased perfusion of the fetal middle cerebral artery. The average birth weights and gestational ages in the study group were markedly reduced in comparison with healthy pregnant women (pregnancy induced hypertension: 1620 g/35 weeks; preeclampsia: 1660 g/34 weeks; HELLP syndrome: 1160 g/31 weeks, respectively). The lowest values for average birth weight and gestational age occurred when all four investigated blood vessels showed pathological Doppler findings: 1180 g/31 weeks (0 to 1 pathological vascular findings: 2780 g/38 weeks; 2 pathological vascular findings: 1845 g/34.5 weeks; 3 pathological vascular findings: 1330 g/31 weeks). This Doppler study underlines the importance of examining four blood vessels: the uterine, the umbilical, and the fetal middle cerebral arteries for a complete analysis of the fetoplacental hemodynamics. On account of the severely impaired hemodynamics observed in the placentas of our patients with hypertensive diseases in pregnancy or HELLP syndrome, we believe the early diagnosis of these disorders by Doppler sonography and an early start of therapy to be essential.

“…In addition, in all studies, the Doppler uteroplacental and umbilical artery velocity waveforms were recorded as previously described [13]. The non-stressed fetal heart rate pattern was classified into two groups: reactive and non-reactive.…”

“…It is associated with the maternal syndrome of preeclampsia [13] and the fetal syndrome of IUGR [5,14]. Doppler ultrasound has helped to identify pregnancies associated with this placental pathology in the maternal and fetal circulations to the placenta [13,14]. On the maternal side, this reduced perfusion to the placenta is an important feature.…”

“…The reason of this difference is that the fetal vessels offer information regarding the adaptation to hypoxemia while the umbilical arteries indicate the possible reduction of maternal-fetal exchanges that are the cause of fetal hypoxemia. Moreover, it has been shown that the increase of the PI in umbilical arteries is proportional to the obliteration of the placental vascular bed [9], but that an obliteration of not less than 60 % must be present before DVWF alterations become detectable [24].…”
