目的探讨腹部B超引导下胚胎移植位置对体外受精-胚胎移植妊娠结局的影响。方法回顾性分析2011年7月-2012年6月在我中心行IVF-ET/ICSI-ET治疗的新鲜胚胎移植共270个周期,根据B超下测量含有胚胎的气液滴距宫底距离的不同分为4组:≤1cm为A组(50例),1.1-1.5cm为B组(91例),1.6-2.0cm为C组(92例),>2cm为D组(37例),分析不同的胚胎移植位置对IVF结局的影响。结果各组间临床妊娠率,种植率,异位妊娠率,早期流产率均无统计学意义(P>0.05)种植率有随胚胎移植位置距宫底距离增加而增高的趋势,异位妊娠率有随胚胎移植位置距宫底距离增加而减小的趋势。结论胚胎移植位置距宫底的距离并不影响移植后妊娠的结局。
Objective To investigate the effect of abdominal B-ultrasound guided embryo transfer on pregnancy outcome of in vitro fertilization-embryo transfer. Methods A total of 270 cycles of fresh embryo transfer treated with IVF-ET / ICSI-ET in our center from July 2011 to June 2012 were retrospectively analyzed. The distance of gas-liquid drops containing embryos from the fundus distance The patients were divided into 4 groups: ≤1cm in group A (n = 50), 1.1-1.5cm in group B (n = 91), 1.6-2.0cm in group C (n = 92) The effect of different embryo transfer sites on IVF outcomes was analyzed. Results There was no significant difference in clinical pregnancy rate, implantation rate, ectopic pregnancy rate and early miscarriage rate among all groups (P> 0.05). The implantation rate increased with the increase of the distance from the end of the uterus to the embryo transfer site. The ectopic pregnancy rate With the location of the embryo transfer from the Palace of the bottom distance increases and decreases. Conclusion The distance from the fundus to the site of embryo transfer does not affect the outcome of pregnancy after transplantation.
