Evaluation of maternal-placental-fetal blood flow in mild preterm placental abruption (PNA) compared with placental tissue morphological characteristics.
Materials and methods. 82 pregnant women with mild PONRP (comparison group) and 15 healthy pregnant women (control group) were examined.
Results. Assessment of utero-placental-fetal blood flow in pregnant women with mild PONRP is characterized by a significant increase in the systolic-diastolic ratio (SDR) and resistance index (RI) in the uterine arteries. No significant differences were found between primiparous and multiparous women. Morphological characteristics of the placenta in primiparous women are characterized by more pronounced dystrophic, hemodynamic and inflammatory changes than in multiparous pregnant women with mild PONRP, which indicates a decrease in the compensatory and adaptive capacity of uteroplacental blood flow.
Summary. Doppler examination of uteroplacental-fetal blood flow is necessary for mild PONRP. It makes it possible to assess the severity of hemodynamic disorders in the myometrium, to assess the condition of the fetus, in which case it is impossible to choose the correct and timely pregnancy management tactics.
