超声检测卵巢巧克力囊肿卵巢间质血流变化的价值

Value of color Doppler ultrasound in detection of blood flow changes within stroma ovarii in patients with chocolate cyst of ovary

目的探讨经阴道彩色多普勒超声检测卵巢巧克力囊肿卵巢间质血流变化的临床价值。方法应用经阴道彩色多普勒超声观察60例卵巢巧克力囊肿患者和60例正常育龄妇女卵巢间质动脉血流显像,测定其血流动力学参数,两组间进行对比分析。结果①卵巢巧克力囊肿卵巢间质动脉血流束纤细,多呈星点状;动脉频谱呈高阻血流,阻力指数(RI)、搏动指数(PI)、动脉收缩期峰值流速/舒张末期血流速度(S/D)均高于对照组,差异有统计学意义(P<0.01)。②年龄>35岁、病程>1年是卵巢巧克力囊肿患者卵巢间质动脉血流难以显示的主要因素;其血流显示区域的不同与病程、囊肿类型(单房或多房)有关。结论经阴道彩色多普勒超声可敏感地评价卵巢巧克力囊肿卵巢间质血流的改变,从而提示并预测卵巢功能状态。

Objective To assess the clinical value of transvaginal color Doppler ultrasound in detection of blood flow changes within stroma ovarii in patients with chocolate cyst of ovary. Methods The blood flow of ovarian stromal artery in 60 patients with chocolate cyst of ovary and 60 normal subjects were observed by transvaginal color Dapple ultrasound, their hemodynamics parameters were measured, the results were compared and analyzed. Results （1）The blood flow of ovarian stromal artery in chocolate cyst of ovary group was slender, and most of that showed star - shape, while arterial spectra showed high- resistance blood flow, and RI（ resistance index）, PI （pulsatility index） and S/D（ peak systolic velocity/ end- diastolic velocity） were higher than those in normal group （P 〈0.0l ）. （2） The age more than 35 and course more than 1 year were the risk factors affected the absence of ovarian stromal blood signals in patients with chocolate cyst of ovary, while the different blood flow area was related with the course and cyst type. Conclusion Transvaginal color Doppler ultrasound can be used as a non - invasive, convenient and sensitive method for assessing blood flow changes within the ovarian stromal artery, and it can predict the ovarial function.
