彩色多普勒超声评价子宫肌瘤高强度聚焦超声治疗前后卵巢动脉血流动力学改变

目的探讨彩色多普勒超声在观察高强度聚焦超声（HIFU）治疗子宫肌瘤前后卵巢血供变化中的价值。方法32例子宫肌瘤患者在HIFU治疗前后行卵巢动脉彩色多普勒超声检查，测定收缩期最大血流速度（Vmax）、舒张末期血流速度（Vmin）、阻力指数（RI）和搏动指数（PI），比较HIFU治疗前后卵巢动脉血流动力学变化。32例患者中随机抽取20例于术前及术后复查时检测卵泡刺激素（FSH）、黄体生成素（LH）、雌二醇（E2）和孕酮（P）。结果32例子宫肌瘤患者HIFU术前后卵巢动脉各血流动力学参数无明显变化，P〉0．05；20例患者HIFU治疗前后卵巢内分泌激素比较差异亦无统计学意义（P〉0．05）。结论HIFU治疗子宫肌瘤对卵巢动脉的血供及功能无明显影响。

Evaluation of ovarian artery hemodynamics changes before and after high intensity focused ultrasound treatment for uterine fibroids by color Doppler ultrasound

Objective To explore the varian artery hemodynamics changes before and after high intensity focused ultrasound （HIFU） treatment for uterine fibroids by color Doppler ultrasound. Methods Thirty two cases were examined by color Doppler ultrasound before and after HIFU treatment for uterine fibroid, the maximal blood flow velocity （ Vmax ） of systolic phase, the minimal blood flow velocity （ Vmin ） of end - diastole, resistance index （RI） and pulsatility index （PI） were measured, and ovarian artery hemodynamic changes were compared before and after HIFU treatment. The follicle stimulating hormone （FSH）, luteinizing hormone （LH）, estradiol（E2） and progestin （P） in 20 of 32 patients were measured before and after HIFU treatment. Results There was no obviously changes of ovarian artery hemodynamics parameters before and after HIFU treatment in 32 patients with uterine fibroids （ P 〉 0.05）, and there was no significant difference of ovarian endocrine secretion hormone before and after HIFU treatment in 20 patients with uterine fibroids （ P 〉 0.05）. Conclusion HIFU treatment of uterine fibroids doesn＇ t effect ovarian blood supply obviously.
