【目的】研究腹部超声引导下胚胎移植对体外受精-胚胎移植结局的影响。【方法】回顾性分析2001年7月至2005年3月,在本中心接受体外受精-胚胎移植(包括卵母细胞内单精子注射)治疗的461名患者521个周期的资料,按照胚胎移植时有无B超引导分为常规胚胎移植组(A组)和超声引导下胚胎移植组(B组),分别有187个周期和334个周期,比较两组患者的临床妊娠率、胚胎种植率、胚胎残留率和异位妊娠率。【结果】A组和B组的周期妊娠率分别是35.8%(67/187)和38.3%(128/334),P>0.05;胚胎种植率分别是17.4%(104/599)和23.2%(179/773),P<0.01;胚胎残留率分别是3.7%(7/187)和0.3%(1/334),P<0.01;异位妊娠率分别是3.0%(2/67)和1.6%(2/128),P>0.05。【结论】腹部超声引导下胚胎移植能提高体外受精-胚胎移植的胚胎种植率,降低胚胎残留率,可能有助于改善临床妊娠率和降低异位妊娠率,是一种有效的胚胎移植方法。
【Objective】 To study the effect of abdominal ultrasound-guided embryo transfer on in vitro fertilization-embryo transfer outcomes. 【Methods】 The data of 521 cycles of 461 patients undergoing in vitro fertilization and embryo transfer (including intracytoplasmic sperm injection) in our center from July 2001 to March 2005 were retrospectively analyzed. According to the data of embryo transfer There were 187 cycles and 334 cycles respectively in the conventional embryo transfer group (group A) and the ultrasound-guided embryo transfer group (group B). The clinical pregnancy rate, embryo implantation rate, Rate of residual embryos and rate of ectopic pregnancy. 【Results】 The pregnancy rates of group A and group B were 35.8% (67/187) and 38.3% (128/334) respectively, P> 0.05. The embryo implantation rates were 17.4% (104/599) and 23.2% 179/773), P <0.01. The rate of embryo remnant was 3.7% (7/187) and 0.3% (1/334) respectively, P <0.01. The rates of ectopic pregnancy were 3.0% (2/67) and 1.6% (2/128), P> 0.05. 【Conclusion】 Transabdominal ultrasound-guided embryo transfer can improve embryo implantation rate and reduce embryo remnant rate in vitro fertilization and embryo transfer, which may be helpful to improve clinical pregnancy rate and reduce ectopic pregnancy rate. It is an effective embryo transfer method.
