目的:探讨应用彩色多普勒超声诊断多囊卵巢综合征(PCOS)的影像学表现及临床价值,为诊断方式提供参考。方法:选取2012年12月~2013年12月收治的PCOS患者120例为观察组,选取同期性激素水平正常女性80例为对照组。两组患者均实施经阴道彩色多普勒超声检查,对比两组患者超声表现及血流动力学结果。结果:PCOS患者卵巢体积相比对照组正常卵巢明显更大[(10.33±2.97)cm3vs(5.62±1.71)cm3],对比差异有统计学意义(P<0.05);卵泡数目较多,平均(23.55±5.35)个;患者间质血流信号主要表现为粗壮条形,在收缩期波峰表现钝缓,且上升比下降速度快;频谱主要表现为高速低阻;相比对照组动脉舒张末期流速(EDV)、动脉收缩期峰值流速(PSV)、黄体生成素(LH)、卵泡刺激素(LH/FSH)更高,阻力指数(RI)、搏动指数(PI)更低,以上指标对比差异均有统计学意义(P<0.05或<0.01)。结论:应用彩色多普勒超声诊断PCOS可靠方便,血流动力学变化可作为提升诊断准确率的参考依据。
Objective: To investigate the imaging findings and clinical value of diagnosis of polycystic ovary syndrome (PCOS) by color Doppler ultrasound and to provide a reference for diagnosis. Methods: A total of 120 PCOS patients admitted from December 2012 to December 2013 were selected as the observation group. Eighty normal female patients with the same sex hormone level were selected as the control group. Transvaginal color Doppler ultrasonography was performed in both groups, and the ultrasound findings and hemodynamic outcomes were compared between the two groups. Results: The ovarian volume of PCOS patients was significantly larger than that of the control group [(10.33 ± 2.97) cm3 vs (5.62 ± 1.71) cm3], the difference was statistically significant (P <0.05) ± 5.35). The interstitial blood flow signal of the patients showed mainly stout bar, blunted slowly at the peak of systolic phase, and the rate of ascending and descending was faster than that of control group. The spectrum showed high speed and low resistance. Compared with the control group, EDV, PSV, LH, LH / FSH, RI and PI were lower than those of the control group Statistical significance (P <0.05 or <0.01). Conclusion: It is reliable and convenient to diagnose PCOS by color Doppler sonography. The hemodynamic changes can be used as the reference basis to improve the diagnostic accuracy.
