摘要
目的：探讨体外受精-胚胎移植中发生异位妊娠的危险因素。方法：回顾分析中山大学附属第二医院生殖中心2001年6月-2008年10月接受体外受精-胚胎移植治疗后42例异位妊娠患者的临床资料。结果：共有779个周期获得妊娠,42例为异位妊娠（5.39%）,其中宫内宫外同时妊娠10例（23.81%）,异位妊娠组与正常妊娠组比较,既往发生宫外孕的比率较高、HCG日内膜平均厚度较薄、移植过程困难比率高。结论：既往宫外孕发生史、HCG日内膜厚度、移植过程困难可能是体外受精-胚胎移植后发生异位妊娠的高危因素。
Objective：To explore the risk factors for ectopic pregnancy（EP） after in vitro fertilization and embryo transfer（IVF-ET）.Methods：A retrospective study of 42 cases of ectopic pregnancies after IVF-ET was performed between June 2001 and October 2008.Results：A total of 779 pregnancy cycles after IVF or ICSI were collected and the rate of EP was 5.39%（42/779）,of which 10 patients（23.81%）were heterotypic pregnancy（HEP）.There was a higher rate of EP history and difficulty in embryo transfer in EP group compared with normal pregnancy group.The thickness of endometrium was thin in EP group on the day of HCG injection.Conclusion：History of ectopic pregnancy,the thickness of endometrium on the day of HCG administration and difficulty in embryo transfer are associated with increased risk of EP.
