三维及彩色多普勒超声对多囊卵巢综合征的辅助诊断价值

目的探讨三维及彩色多普勒超声对多囊卵巢综合征(PCOS)的辅助诊断价值。方法对中国医科大学附属盛京医院2005年2月至2007年6月收治的60例PCOS患者和60例健康育龄女性进行三维及彩色多普勒超声检查,检测卵泡数目、三维容积和血流动力学指标,并进行对比分析。结果PCOS组的卵泡数目、卵巢容积、卵巢间质容积、卵泡容积大于对照组分别为(16.91±4.34)个、(12.56±3.96)cm3、(11.49±3.50)cm3、(1.07±0.61)cm3对(5.48±2.10)个、(4.76±1.78)cm3、(4.43±1.74)cm3、(0.32±0.21)cm3],差异均有统计学意义(P<0.01);卵巢间质内动脉阻力指数低于对照组(0.53±0.06对0.65±0.09),收缩期峰值血流速度高于对照组(12.68±3.10)cm/s对(9.30±1.64)cm/s],差异具有统计学意义(分别P<0.01,P<0.05)。结论三维超声和彩色多普勒超声增加了鉴别PCOS的客观定量指标,对多囊卵巢综合征有较高的辅助诊断价值。

Value of three-dimensional and color Doppler ultrasonography in the diagnosis of polycystic ovarian syndrome

Objective To evaluate the diagnostic value of three-dimensional (3D) and color Doppler ultrasonography in polycystic ovarian syndrome (PCOS). Methods The ovarian 3D volumes,follicle number and ovarian stromal blood flow indices were measured in 60 patients with PCOS and 60 normal controls. Results The ovarian volume,stromal volume and follicular volume and follicle number in PCOS group were significantly higher than those in control group .The stromal blood flow resistance index was significantly lower and peak systolic blood flow velocity was significantly higher in PCOS group than those in the control group.Conclusion The 3D volume measurements and blood flow indices allow objective and quantitative evaluation on the ovary in PCOS. 3D and color Doppler ultrasound might be a valuable tool for the diagnosis of PCOS.
