1982年,Tanka等首次用氨甲喋呤成功地治疗了一例间质妊娠,而Mashiack等证明某些异位妊娠可只用观察处理.瑞典Goteborg大学Sahlgren医院研究人员将前列腺素(PG)F2a注入受累的输卵管和含有黄体的卵巢成功地治疗了9例小的、未破裂的输卵管妊娠妇女.然而,研究人员说,目前还不清楚哪些异位妊娠病例适合此种治疗,还不能确定PGF2a是否是理 In 1982, Tanka et al. Successfully treated one case of interstitial pregnancy with methotrexate for the first time, while Mashiack et al. Demonstrated that some ectopic pregnancies may be treated only with observation. Researchers at Sahlgren Hospital, Goteborg University, Sweden injected prostaglandin (PG) F2a into the affected fallopian tubes And ovary containing lutein successfully treated 9 small, unruptured tubal pregnant women However, the researchers said it is unclear which ectopic pregnancy cases are suitable for this treatment, it is not yet possible to determine whether PGF2a is reasonable
