目的：探讨经阴道彩色多普勒超声（TVCDS）诊断多囊卵巢综合征（PCOS）的效果。方法选取42例PCOS患者和42例正常健康育龄妇女，均行TVCDS检查，比较两组患者的卵巢物理学指标和血流动力学指标。结果PCOS组的卵泡数（FN）、卵巢体积（OV）、卵巢间质面积（SA）、卵巢总面积（TA）、SA/TA均明显多于或大于对照组（P<0.01），而PCOS组的最大卵泡直径则明显小于对照组（P<0.01）；PCOS组的收缩期峰值血流（PSV）、舒张期末期血流速度（EDV）均明显高于对照组（P<0.01），而PCOS组的搏动指数（PI）、阻力指数（RI）则明显小于对照组（P<0.01）。结论TVCDS可较直观、准确地显示卵巢特征，对辅助诊断多囊卵巢综合征具有重要的临床价值。%Objective To explore the effectiveness of TVCDS (Transvaginal Color Doppler Sonography) in diagnosis of PCOS (Polycystic Ovary Syndrome). Methods Altogether 42 cases of PCOS and 42 healthy women at reproductive age were selected and scanned by TVCDS so as to compare the physical and hemodynamic indexes of ovaries between PCOS Group and Contrast Group. Results PCOS Group was obviously superior to Contrast Group (P<0.01) in quantities of FN (Follicular Number), OV (Ovary Volume), SA (Stromal Area), TA (Total Area) and SA/TA. However, the diameter of the biggest follicle in PCOS Group were much smaller than that in Control Group (P<0.01). Moreover, PCOS Group showed much higher PSV (Peak Systolic Velocity) and EDV (End Diastolic Velocity) in comparison with Control Group (P<0.01), but PI (Pulsatility Index) and RI (Resistance Index) of PCOS Group were much less than Control Group (P<0.01). Conclusion TVCDS could directly and exactly reveal the characteristics of ovaries, and it played an important role in auxiliary diagnosis of PCOS.
