BLOOD-FLOW VELOCITY WAVE-FORMS IN THE UTE ROPLACENTAL ARTERIES - CORRELATION WITH PLACENTAL MORPHOLOGY IN PREECLAMPSIA

Within a group of preeclamptic women we found severe histologic placen tal pathology with functional relevance when both the uteroplacental a nd fetoplacental flow velocity waveforms showed elevated resistance in dices. These pathological findings were a reduced decidual area, infar ction and villus maturation failures with a high rate of intrauterine growth retardation, acidosis and premature delivery. In cases with nor mal flow velocity waveforms these pathologic findings were much rarer although the patients were preeclamptic, too.
