[Evaluation of umbilical Doppler parameters in relation to placental morphology in the third trimester of normal pregnancy].
The purpose of this study was to find out whether there was a relationship between placental morphology and velocimetric measurements of the umbilico-placental circulation. The Doppler parameters measured at the placental insertion of the umbilical artery between 28 and 40 weeks in 145 normal pregnancies were analysed in relation to placental maturation, as evaluated by real-time ultrasonography. A significant relationship between gestational age and fetal measurements was observed in relation to the ultrasonographic progress of placental maturity. As the placental grading changed from immature to mature, no variations in Doppler parameters and placental thickness were noted. It is concluded that anatomical placental changes evaluated by ultrasonography do not correlated with the changes observed in Doppler parameters during the third trimester of normal pregnancies.
