摘要
目的 探讨体外受精-胚胎移植（IVF-ET）后异位妊娠（EP）发生的风险。方法 对我院2005年1月至2007年6月接受IVF-ET的590例临床资料进行回顾性分析。结果 IVF-ET后EP发生率为7．07％，移植困难的胚胎移植（ET）女性EP的发生明显高于无移植困难妇女。超声引导与否及移植管放置位置（1．1～2．0）cm对EP的发生无明显影响（P〉0．05）。结论 避免困难移植可有效减少EP的发生。
Objective To analyze the risk factors of ectopic pregnancy after in vitro fertilization and embryo transfer （IVF-ET）. Methods A total of 590 cases after IVF-ET from the Centre between January 2005 and June 2007 were retrospectively analyzed.Results In 590 cases of IVF-ET ,212 clinical pregnancies were obtained. 15 （7.07%） of them were ectopic pregnancies. The data showed that ectopic pregnancy was at present more prevalent among patients who had difficult transfers （ P 〈 0.05）. No statistical difference was found between the ectopic pregnancy rate and embryo transfer with or without ultrasound guidance and embryo transfer depth（ 1.1 - 2.0 cm）. Conclusion Difficult transfers were the risk factor leading to develop an ectopic pregnancy after in-vitro fertilization and embryo transfer. Transfer technique influences the ectopic pregnancy rate.
