目的评价腹部超声引导下胚胎移植位置对体外受精-胚胎移植(IVF-ET)结局的影响。方法回顾分析在本中心行IVF-ET病人586例610个移植周期的资料,比较胚胎移植位置和临床结局之间的关系。结果根据B超所测量移植后含有胚胎的培养液强回声距宫底的距离分为4组,各组间年龄、获卵数、移植优质胚胎数、流产率以及异位妊娠率比较,差异均无显著意义(P>0.05);>2.0 cm组的临床妊娠率及胚胎种植率显著高于<1.0 cm组,差异有显著性(χ2=102.4、123.6,P<0.05)。结论腹部超声引导下将胚胎移植于距宫底2.0 cm处或宫腔中下1/3处临床妊娠率和胚胎种植率较高。
Objective To evaluate the effect of abdominal ultrasound-guided embryo transfer on the outcome of in vitro fertilization-embryo transfer (IVF-ET). Methods The data of 586 cases of 610 transplant cycles of IVF-ET in our center were retrospectively analyzed. The relationship between the location of embryo transfer and the clinical outcome was compared. Results According to the B measured by measuring the transplanted embryo-containing culture solution strong echo from the Palace of the distance is divided into four groups, the age of the group, the number of oocytes retrieved, the number of transplanted good embryos, miscarriage rate and ectopic pregnancy rate, the difference was (P> 0.05). The clinical pregnancy rate and embryo implantation rate in> 2.0 cm group were significantly higher than those in <1.0 cm group (χ2 = 102.4, 123.6, P <0.05). Conclusion Under the guidance of abdominal ultrasound, the embryo is transplanted at a distance of 2.0 cm from the end of the uterus or 1/3 of the uterine cavity with a higher clinical pregnancy rate and embryo implantation rate.
