[Estimation of fetal middle cerebral artery peak systolic velocity at 18-39 weeks of gestation in Polish population].

Objectives: The aim of this paper was to establish normal values of fetal middle cerebral artery peak systolic velocity (MCA-PSV) between 18-39 weeks' gestation in the Polish population and to compare the results with values published by other authors, for different populations seeking the discrepancies between them.
Material and Methods: 280 healthy pregnant women from the Polish population underwent ultrasound examination. The cross-sectional data were obtained based on the measurements of fetal middle cerebral artery peak systolic velocity A chart of normal MCA-PSV values as a function of the gestational age was constructed.
Results: Normal ranges for MCA-PSV in the Polish population were established. The results were compared with values published by other authors, for different populations.
Conclusions: The use of MCA-PSV measurements has proven itself to be a reliable method in diagnosis of fetal anemia. Differences in normal values of MCA-PSV in the Polish population compared with other nations have been observed.
