RESUMO
Objective To provide the normal hemodynamic parameters of uterine several arteries in reproductive women.Methods The hemodynamic parameters including peak systolic velocity(PSV),end diastolic velocity(EDV),resistance index(RI),pulsatility index(PI)and systolic/diastolic velocity ratio(S/D) of uterine artery(UTA),arcuate artery(AA),radial artery(RA)and spiral artery (SA) in 66 reproductive women were studied by transvaginal color Doppler(TVCD).The results were analyzed with T test.Results The flow of uterine several arteries in normal reproductive women was all detected well.From UTA to SA,parameters gradually decreased.In the secretory phase of menstrual cycle,the change of SA which EDV value was higher and RI value was lower was the most obviously.Conclusion The uterine hemodynamics in productive period is in close relalionship with menstrual cycle.We can predict the time of menstrual cycle according RI value of SA.
