经阴道超声对多囊卵巢综合征的诊断价值

Diagnostic value of polycystic ovary syndrome by transvaginal ultrasonography

目的:探讨彩色多普勒超声对多囊卵巢综合征(PCOS)的诊断价值。方法:对43例PCOS患者(PCOS组)和25例月经周期规则有正常排卵者(对照组)进行经阴道二维及彩色多普勒超声检查,观测其卵巢体积(OV)、卵泡数目(FN)、卵巢间质内血流形态特征及其血流动力学指标,并进行对比分析。结果:PCOS组的卵巢体积、卵泡数目大于对照组,差异有统计学意义(P<0.001);收缩期峰值流速(PSV)高于对照组,差异有统计学意义(P<0.01),而阻力指数(RI)、搏动指数(PI)低于对照组,差异有统计学意义(P<0.001)。PCOS组卵巢间质内血管显示清晰、数量丰富(100%),其中91.9%的卵巢可见1支纵向贯穿卵巢间质的较粗血管,而对照组卵巢间质内血流呈散在点状。结论:经阴道二维及彩色多普勒超声对多囊卵巢综合征有较高的诊断价值。

Objective： To evaluate the diagnostic value of color Doppler uhrasonography for polycystic ovary syndrome （PCOS）. Methods： Transvaginal ultrasound examinations were performed in 43 patients with PCOS and in 25 women with regular menstrual cycles. Two-dimentional ultrasound and color Doppler flow imaging （CDFI） were performed in all patients. Mean ovarian volume （OV）, follicle number （FN） and ovarian stromal blood flow were measured. Results： OV, FN and peak systolic velocity （PSV） in PCOS group were significantly higher than in the control group （P〈 0. 001）. While the resistance index （RI） and pulsitive index （PI） apparently were significantly lower than in the control group （P 〈0. 001）. Vascularization of the ovarian stroma was more abundant in patients with PCOS than in control women （100%）. Seventy-nine ovaries of total 86 ovaries in PCOS group （91.9%） showed an obvious artery penetrating the ovarian stroma. Conclusions： Transvaginal color Doppler ultrasonography assessment of ovary combined with two-dimentional ultrasounography is a valuable tool for the diagnosis of PCOS.
