[Informative value of Doppler ultrasonography in predicting the development of gestoses and fetal growth retardation syndrome].

Doppler studies in 102 women with uncomplicated pregnancies have indicated that uteroplacental and fetoplacental circulations as low-resistant vascular systems develop at 13-16 week's gestation. Doppler examination early in the second trimester allows one to identify hemodynamic disorders in the materno-placental-fetal unit and predict their onset as well as toxemia of pregnancy and intrauterine growth retardation.
