经阴道彩色多普勒观察卵巢血流灌注与卵泡发育的关系

目的:探讨不孕症患者在药物治疗过程中卵巢血流灌注与卵泡发育的关系。方法:应用阴道彩色多普勒超声对60例药物治疗中的不孕症患者84个排卵周期的卵泡发育及卵巢血流灌注情况进行观察。结果:随着卵泡发育,卵巢血流越来越丰富,血流阻力指数(RI)及动脉收缩期峰值流速(S)/舒张末期血流速度(D)比值越来越低。最佳受孕卵泡大小为21.0±2.5mm,至排卵前RI为0.57±0.05,S/D为2.20±0.50,妊娠组的卵泡大小及血流灌注明显优于非妊娠组。结论:不孕症患者治疗过程中卵巢内血流指标与卵泡的大小和受孕率有关。

Relationship between Ovarian Perfusion and Follicular Growth Observed by Transvaginal Color Doppler Imaging

Objective: To explore the relationship between the follicular growth and the ovarian perfusion of the infertile women being treated with medicine. Methods: The follicular growth and the ovarian perfusion of 84 ovulation cycles in 60 infertile women during treatment were monitored with transvaginal color ultrasound. Results: The ovarian perfusion became more and more abundant and coincident with the follicular development. However, in the ovulation period RI and S/D turned to low level. The best size of the follicle was 21.0±2.5 mm during the ovulation. RI was 0.57±0.05, S/D was 2.20±0.50 before ovulation. The ovarian perfusion and the size of the follicle of the conceived group were obviously better and larger than those of the nonpregnant group, respectively. Conclusion: The follicular development and the ovarian perfusion play vital role in the pregnancy of the infertile women during treatment with medicine.
