经阴道彩色多普勒超声监测卵泡发育及观察子宫内膜血流变化

摘要

目的　观察卵泡发育成熟度及子宫内膜厚度和子宫螺旋动脉血流阻力指数的相互关系。方法rn应用经阴道超声监测56例正常月经周期的卵泡发育情况、子宫内膜增殖期厚度及子宫螺旋动脉各项参数。结果　排卵前卵泡直径平均 2.1 cm，并移至卵巢表面，距卵巢包膜≤1.0 cm时即将排卵。子宫内膜相应增厚（达1.4 cm)，螺旋动脉阻力指数降低(0.45±0.03)。结论　经阴道超声多普勒监测卵泡生长发育，观察子宫内膜厚度及螺旋动脉血流阻力指数，可指导临床提高受孕率。%Objective　To observe the relationship among the degree of maturation of development of ovarian follicle and endometrial thickness and resistance index of uterine helicine arteries.Methods　Fifty six cases of normal menstrual cycle were studied by transvaginal color Doppler flow imaging.Results　Diameter of ovarian follicle increased and moved to the surface of ovary before ovulation,endometrium thickened and resistance index of uterine helicine arteries decreased.Conclusions　Observation of the development of ovarian follicle by transvaginal color Doppler flow imaging is helpful to improve regnancy rate.
