经阴道超声对体外受精-胚胎移植中子宫内膜容受性的评价

目的应用超声技术探索体外受精-胚胎移植(IVF-ET)患者(hCG)注射日内膜厚度、类型、血流状态对妊娠是否具有预测价值。方法31例女性患者,采用长周期方案促排卵,于hCG日行经阴道超声检查,检测内膜厚度、类型,计数内膜血流,估算内膜血流面积比。结果15例妊娠,妊娠组内膜厚度、回声类型与未妊娠组无差异,妊娠组内膜血流计数及内膜血流面积比均较未妊娠组增加。结论hCG日子宫内膜厚度与回声类型不能为IVF-ET结局提供可信的预测,内膜血流灌注对胚胎能否种植具有一定预测性,血流丰富,能提高妊娠率。

Evaluating Endometrial Receptivity Using Transvaginal Ultrasonography in IVF-ET

Objective To evaluate the role of endometrial thickness,echo pattern,blood flow status detected by ultrasonography on the day of hCG injection in predicting pregnancy in an IVF-ET program.Methods 31 women undergoing controlled ovarian hyperstimulation for IVF.Transvaginal ultrasonography detecteded endometrial thickness,echo pattern,blood flow number and percent of blood flow area on the day of hCG injection.Results Mean endometrial thickness and endometrial pattern in 15 pregnant women did not differ statistically in nonpregnant women.Blood flow number and ratio of blood flow area of endometria in pregnant women were more than nonpregnant women.Conclusions Endometrial thickness and pattern on the day of hCG injection did not predict occurrence of pregnancy.Plenty endometrial blood flow appeared to favor embryo implantation and pregnancy.
