经直肠彩色多普勒超声对多囊卵巢综合征卵巢间质内血流动力学的研究

Transrectal color Doppler ultrasonography detection of the haemodynamic changes within ovarian stromal blood flow in patients with polycystic ovary syndrome

目的:观测多囊卵巢综合征(PCOS)卵巢间质内血流动力学的改变。 方法:应用经直肠彩色多普勒超声 (TRS)对41例PCOS和10例正常育龄女性于月经周期的2～5天或闭经患者任意一天观察卵巢间质内血流显像, 并检测其血流动力学指标。 结果:PCOS卵巢间质内可显示特征性的始自卵巢门纵向卵巢间质的较粗血管。卵 巢间质内动脉峰值流速(Vmax)、搏动指数(PI)、阻力指数(RI)分别为:右侧卵巢(18.99±3.12)cm/s、0.74±0.12、 0.50±0.03,左侧卵巢(18.76±3.23)cm/s、0.75±0.11、0.49±0.04。 结论:PCOS卵巢间质内血流丰富,TRS作 为一项无创、方便的检查可敏感地评价卵巢间质内血流动力学的改变。

Objective: To observe the haemodynamic changes within ovarian stromal blood flow in patients with polycystic ovary syndrome(PCOS). Methods: 41 patients with PCOS and 10 ovulatory women underwent transrectal ultrasound associated with Doppler flow measurement of the artery within ovarian stroma during the early follicular phase (days 2-5 of the menstrual cycle) or any day in patients with amenorrhea . Results:The peculiar vascular pattern wich one prominent blood vessel showed passing through the ovarian stroma from ovary gate. This sign was observed in all ovaries in patients with PCOS.There was no significiant difference in Vmax、PI、RI between left and right ovary.The Vmax,PI,RI of the right ovarian stromal artery were (18.99±3.12)cm/s, 0.74±0.12, 0.50±0.03 respectively. The indices of the left ovarian stromal artery were (18.76±3.23)cm/s, 0.75±0.11, 0.49±0.04 respectively. Conclusion: Vascularization of the ovarian stroma is prominent in patients with PCOS than in the control. The decreased vascular resistance to ovarian stromal perfusion in patients with PCOS may lead to perfusion increasment. TRS can be used as a non-invasive, convenient, and sensitive method for assessing the blood flow within the ovarian stroma.
