多囊卵巢综合征的子宫内膜厚度及卵巢血液改变的超声诊断

Ultrasonography of endometrial thickness and ovarian perfusion in polycystic ovary syndrome

目的探讨多囊卵巢综合征(PCOS)的子宫内膜厚度及卵巢血液改变的超声诊断价值。方法对47例多囊卵巢综合征患者(PCOS组)和32例健康人(对照组)进行超声检查,观察子宫内膜的厚度及卵巢血液参数变化。结果PCOS组的子宫内膜厚度和收缩期峰值血流速度(PSV)明显大于对照组,差异有统计学意义(P<0.05),不同停经天数PCOS患者的子宫内膜厚度和卵巢PSV差异有统计学意义,以>90 d组的值最高;PCOS组和对照组卵巢的阻力指数(RI)差异有统计学意义,PCOS组明显低于对照组(P<0.05),不同停经天数PCOS患者的卵巢RI值差异有统计学意义,以>90 d组的值最低。结论超声检查显示PCOS患者的子宫内膜增厚,卵巢血流丰富,阻力明显减低,并且随停经时间而变化。超声诊断对于PCOS具有重要的临床意义。

Objective To explore the ultrasonography of endometrial thickness and ovarian perfusion in polycystic ovary syndrome（PCOS） patients.Methods Forty-seven patients of PCOS and 32 healthy controls were examined,and the thickness of endometrium and the changes in ovarian perfusion were observed.Results The thickness of endometrium was thicker and the ovarian peak systolic blood flow velocity（PSV） was faster in PCOS group than in control group（P0.05）.There was statistical significance in the endometrial thickness and ovarian PSV among PCOS groups with different menolipsis days（P0.05）,and the highest values were found in the group with over 90 menolipsis days.The ovarian resistance index（RI） was lower in PCOS group than in control group（P0.05）.There was statistical significance in ovarian RI among PCOS groups with different menolipsis days（P0.05）,and the value was lowest in the group with over 90 menolipsis days.Conclusion Ultrasonography shows that PCOS patients have increased endometria,rich ovarian perfusion and low blood flow resistance which change with menolipsis days.So ultrasonography is clinically significant in the diagnosis of PCOS.
