Abstract
【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
