经阴道彩超对不孕症的应用研究

Application of Transvaginal CDFL to Lnfertility

通过对７４例不孕症患者经阴道彩超监测，提高受孕率达６０．８％的应用研究，探讨了周期性卵泡发育、子宫内膜增殖变化、子宫螺旋动脉血流阻力指数三者之间与受孕的关系。将受孕和未受孕妇女经阴道彩超监测的各项参数值作统计分析，结果表示：受孕组妇女的卵泡发育与子宫内膜增厚呈正相关性ｒ２＝０．０３，排卵期子宫螺旋动脉血流丰富呈高振幅连续波型，阻力指数偏低；未受孕组妇女的卵泡发育与子宫内膜增厚缺乏周期性变化，排卵期子宫螺旋动脉血流纤细呈低振幅非连续波型，阻力指数明显增高。两组统计结果具有显著差异Ｐ＜０．０１。

In the paper by application of TVCDFI to 74 infertile women which increase the conception rate by 60.8 percent, the relation between the periodic ovum-growth, the endometrium change, and uterine aorta blood folw resistance index and pregnancy was discussed. All parameters of pregnant and fallow women examined by the transvaginal CDFI weranalyzed statistically. The results show that the ovum-growth of the pregnant women reveals a positive correltion r=0.03 with the increase of the endometrium thickness, the uterine aorta blood during ovulatory phase is abundant and RI is lower; but the ovum-growth of fallow women has no periodic change with the increase of the endometrium thickness, the uterine aorta blood during ovuloatory phase is fine and RI is high obviously. The statistics are very different in two cases(P<0.01).
