To present a rare case of tubal ectopic pregnancy in a woman using Implanon® after a previous contralateral ectopic pregnancy that had occurred without contraceptive use.
A 26-year-old woman presented with an ectopic pregnancy conceived whilst having an etonogestrel implant (Implanon®) in situ. A laparoscopic salpingectomy was performed and the implant was removed. Two years previously she had been treated for a contralateral ectopic pregnancy following which the implant was inserted.
Implanon®, being a highly effective long-acting reversible method of contraception, has been advocated in women with previous ectopic pregnancy. However, as demonstrated by this case, ectopic pregnancy may exceptionally supervene even in the absence of identified risk factors for contraceptive failure.
介绍一例罕见病例，一名女性在先前对侧未使用避孕药具时发生异位妊娠后，使用依伴侬（Implanon®）期间再次发生输卵管异位妊娠。
一名26岁女性，在原位植入依托孕烯植入剂（依伴侬，Implanon®）期间发生异位妊娠。进行了腹腔镜输卵管切除术并取出了植入剂。两年前，她曾因对侧异位妊娠接受治疗，之后植入了该植入剂。
依伴侬是一种高效的长效可逆避孕方法，一直被推荐用于有过异位妊娠史的女性。然而，正如本病例所示，即使在没有确定的避孕失败风险因素的情况下，异位妊娠也可能异常发生。
