Qualitative Study of Color Doppler Ultrasound on Fetus Umbilical Artery and Placenta Function

Purpose To investigated the linear relationship between the late pregnancy umbilical artery and placenta physiological on pathological change and evaluate the placenta function and the perinata pregonoses. Methods Through to people of late pregnancy umbilical artery and abdominal aorta were investigated, using color Doppler ultrasound, the resistance index(RI), the passe index(PI) and the peak syslolis/diastolic ratio(S/D) were calculated, photographed and analyoised statistically. 20 placenta of aormal pregnanul and 7 placenta of abnormal pregnancy were choose at random and were checked pathologically by the same standard, to record the go cases of neonate Apgar score. Results Fetus umbilical artery blood stream RI=0.56±0.08, S/D=2.1±0.4, the matuse degree of the placenta was II°. Few villi were degenerated and had nodosity, bister and calcification, fetus abdominal aorta blood stream PI=1.48±0.49, S/D=3.1±0.8, fetus in good condition, neonate apgar score most was 9～10cent/min. Conclusion There was linear relationship between the fetus umbilical artery and placenta function. [
