摘要
目的探讨经阴道三维能量多普勒超声测定子宫内膜及内膜下容积、内膜及内膜下血流指数对人工周期冷冻胚胎复苏移植结局的预测价值。方法应用经阴道三维能量多普勒超声,对131例接受人工周期冷冻胚胎复苏移植的不孕患者,于复苏当日进行子宫内膜厚度、内膜有无"三线"征、内膜及内膜下容积、内膜及内膜下区域的血管化指数(VI)、血流指数(FI)、血管化血流指数(VFI)测定,根据妊娠与否分为妊娠组与未妊娠组,比较两组间各参数的差异。结果131例复苏移植患者,86例临床妊娠,妊娠率65.6%,种植率54.2%。子宫内膜及内膜下容积、内膜有无"三线"征、内膜及内膜下VI、FI、VFI在两组间均无统计学差异。移植优质胚胎组妊娠率和种植率均显著高于未移植优质胚胎组,P<0.05。结论经阴道三维能量多普勒超声不能有效预测人工周期冷冻胚胎移植的临床结局,是否移植优质胚胎可能是预测妊娠结局的关键因素。
Objective To investigate the value of three-dimensional power Doppler ultrasound for frozen-thawed embryo transfer in hormonally controlled cycles. Methods One hundred and thirty-one patients undergoing frozen-thawed embryo transfer cycles were recruited. Transvaginal 3D power Doppler ultrasound examination was performed on the day of frozen-thawed embryo to determine endometrial thickness, endometrial pattern triple line, endometrial and sub-endometrial volume, vascularization index (VI) ,flow index(FI) and vascularization flow index (VFI)of endometrial and subendometrial regions by the Same experienced sonographers. The patients were divided into pregnant group and non-pregnant group according to pregnant outcome. The data between the two groups were compared and analysed. Results 86 patients had pregnant,the pregnancy rate was 65.6% ,the implantation rate was 54. 2%. There were no significant differences between the pregnant group and non-pregnant group in endometrial thickness, endometrial morphology, endometrial and sub-endometrial volume, endometrial and subendometrial VI, FI, VFI (P 〉 0. 05). The pregnancy rate of high quality embryo transfer group were higher than the other group without high quality embryo transfer,P 〈 0. 05. Conclusions Transvaginal 3D power Doppler ultrasound can not predict the pregnancy outcome during frozen-thawed embryo transfer in hormonally controlled cycles,whether high quality embryo transfer should be more important.
