Abstract:
In this study the umbilical artery and uterine artery blood flow was measured by Acuson 128 color computer ultrasound in 90 healthy pregnant women, and the reference ranges and mathematical models of its indices were established. The variation of observers and measurement time and the effect of different areas of the same vessel on measured blood flow values were also studied. The results show reducing of resistance and increasing of blood flow of the umbilical and uterine arteries in healthy pregnancy with increased gestational age. Doppler blood flow measurement has a good repeatability and is worth while to be used universally. The Doppler signals shound be recorded from near placenta part of umbilical artery and upper branch of uterine artery in a side near to placenta.
