摘要:

目的:比较剖宫产后瘢痕子宫患者与非瘢痕子宫患者在体外受精/胞浆内单精子注射-胚胎移植(IVF/ICSI-ET)治疗中的临床结局。方法:回顾性分析2016年1月—2018年12月在我中心行首次IVF-ET的患者共3 331个周期,其中A组249个周期(剖宫产后瘢痕子宫组),B组3 082个周期(非瘢痕子宫组),比较2组患者的总体临床特征,并分别比较在行囊胚或卵裂期胚胎移植时2组患者的妊娠结局。结果:在囊胚移植及单卵裂期胚胎移植者中,2组患者的优胚移植率、胚胎着床率、临床妊娠率、异位妊娠率、流产率、活产率和多胎率差异无统计学意义(P>0.05),A组早产率高于B组,差异有统计学意义(P<0.05)。在双卵裂期胚胎移植者中,A组患者的优胚移植率、胚胎着床率、临床妊娠率、活产率和多胎率均低于B组,差异有统计学意义(P<0.05),2组患者异位妊娠率、流产率和早产率差异无统计学意义(P>0.05)。结论:在胚胎条件类似的情况下,行单胚胎移植的剖宫产后瘢痕子宫的患者除早产率升高外,可获得与非瘢痕子宫患者类似的临床妊娠结局。双胚胎移植的临床结局仍需进一步研究。

Abstract:

Objective: To compare the clinical outcomes of IVF/ICSI-ET in patients with or without scared uterus after cesarean sections. Methods:A total of 3 331 cycles of IVF/ICSI treatment during Jan 2016 to Dec 2018 were recruited in this retrospective study. They were divided into two groups: the cycles in group A had histories of cesarean sections (n=249),the cycles in group B were nulliparous or had histories of vaginal delivery (n=3 082). The overall clinical characteristics were compared between the two groups, and the pregnancy outcomes after blastocyst transfer or cleavage stage embryo transfer were also compared. Results: There were no significant differences in the rate of high quality embryo transferred, embryo implantation rate, clinical pregnancy rate, ectopic pregnancy rate, miscarriage rate, live birth rate, multiple pregnancy rate between the two groups when the blastocyst or single cleavage stage embryo was transferred (all P>0.05), but the preterm delivery rate was significant higher in group A(P<0.05). The rate of high quality embryo transferred, embryo implantation rate, clinical pregnancy rate, live birth rate, multiple pregnancy rate were significant lower in group A than those in group B when double cleavage stage embryos were transferred (all P<0.05), but the ectopic pregnancy rate, miscarriage rate, and preterm delivery rate were similar in the two groups(all P>0.05). Conclusions:The clinical outcomes of IVF/ICSI-ET treatment are similar between the patients with or without scared uterus when single embryo is transferred,except an increased rate of preterm delivery in patients with scared uterus. It is necessary to study further the clinical outcomes of double embryos transfer in those patients with scared uterus.
