[Blood flow profile in the uterine artery. Correlation with placental morphology and clinico-obstetrical data within the scope of pre-eclampsia].

Within a group of preeclamptic women we found severe histologic placental pathology with functional relevance when both the uteroplacental and fetoplacental flow velocity waveforms showed elevated resistance indices. These pathological findings were a reduced decidual area, infarction and villus maturation failures with a high rate of intrauterine growth retardation, acidosis and premature delivery. In cases with normal flow velocity waveforms these pathologic findings were much rarer although the patients were preeclamptic, too.
