[Morphologic and dopplerometric characteristics of spiral arteries in chronic placental insufficiency].
Placental basal membrane of 156 females of the reproductive age with various forms of placental insufficiency was quantitatively studied. Dopplerometry of spiral arteries with calculation of the resistance index (RI) was performed longitudinally at 20-40 weeks of the pregnancy. Non-complete gestational restructurisation resulted in the decrease of circulation in these vessels with high values of RI and this is one of causes in delay of fetus development. High values of RI is an additional criterion of differential diagnosis of chronic placental insufficiency.
