经阴道彩色多普勒超声对健康生育期妇女卵巢动脉血流状况的评价

目的探讨健康生育期女性卵巢血流在正常月经周期中血流动力学变化的特点及规律,为临床了解卵巢血流的生理和病理变化提供客观的参考指标。方法应用经阴道彩色多普勒超声对50例健康生育期女性的卵泡期、排卵期、黄体期及黄体萎缩期进行检查,观测卵巢动脉收缩期峰值流速(PSV)、舒张末期流速(EDV)、血流阻力指数(RI)、搏动指数(PI)及收缩与舒张末流速比(S/D)等指标。结果除卵泡期、黄体萎缩期之外,卵巢动脉的EDV、RI、PI、S/D组间比较均存在显著性差异(P0.05),黄体期RI、PI、S/D最低,黄体萎缩期RI、PI、S/D最高(P0.05)。结论健康生育期女性在正常月经周期中卵巢动脉血流呈周期性变化,其血供状态与功能状态密切相关。通过检测血流参数可为临床了解卵巢功能提供客观的参考指标。

Transvaginal color Doppler ultrasound of ovarian artery blood flow in healthy women of reproductive age

Objective To provide reference standard for physiological and pathological changes of ovarian blood flow. Methods Color Doppler ultrasound of ovarian artery blood flow was performed on 50 healthy women of reproductive age. Ovarian artery peak systolic velocity （PSV）, end-diastolic velocity （EDV）, blood flow resistant index （RI）, pulsatility index （PI）, and systolic to end diastolic ratio （S/D） were studied in the follicular, ovulation, luteal and luteal atrophy phases. Results There was a significant difference （P 〈0.05） among the ovarian artery EDV, RI, PI, S/D of different groups except for the follicular and luteal atrophy phases. The RI, PI, S/D of luteal phase were the lowest while those of the luteal atrophy phase were the highest （P 〈0.05）. Conclusion There are cyclical ovarian artery blood flow changes in healthy women of reproductive age. There is close relation between the blood supply and the functional status of the ovaries.
