Abstract: Ectopic pregnancy is identified with the widely-applied assisted reproductive technology (ART). Bilateral ectopic pregnancy is a rare form of ectopic pregnancy which is difficult to be diagnosed at the pre-operation stage. In this paper, we presented an unusual case of heterochronic bilateral ectopic pregnancy after stimulated intrauterine insemination (IUI), where there has been a delay of 22 d between the diagnoses of the two ectopic pregnancies. Literature was reviewed on the occurrence of bilateral ectopic pregnancy during the past four years in the MEDLINE database. We found 16 cases of bilateral ectopic pregnancy reported since 2008, and analyzed the characteristics of those cases of bilateral ectopic pregnancy. We emphasize that ovulation induction and other ARTs may increase the risk of bilateral ectopic pregnancy. Because of the difficulty in identification of bilateral ectopic pregnancy by ultrasonography, the clinician should be aware that the treatment of one ectopic pregnancy does not preclude the occurrence of a second ectopic pregnancy in the same patient and should pay attention to the intra-operation inspection of both side fallopian tubes in any ectopic pregnancy case.

促排卵后的不同步双侧异位妊娠

研究目的：报道一例不同步双侧异位妊娠，并回顾相关文献，总结规律。
创新要点：第一次报道了不同步的双侧异位妊娠。
研究方法：对促排卵后行宫腔内人工授精病人发生非同步双侧输卵管妊娠的病例进行报告，辅以人绒毛膜促性腺激素（hCG）值波动曲线、超声图像以及病理切片加以阐述；同时回顾2008年以来关于双侧异位妊娠的文献，并分析病例特征。
重要结论：促排卵后可能会提高双侧异位妊娠风险，一侧异位妊娠发生后，需要注意对侧是否也存在异位妊娠。
