A case of heterotopic pregnancy is presented. A search of the English literature reveals the present case to be the first instance in which a living second-trimester abdominal fetus has been extracted while its placenta remained undisturbed, and the intrauterine pregnancy progressed normally to term.
本文报告一例异位妊娠病例。检索英文文献发现，本病例是首例在孕中期取出存活的腹腔胎儿时其胎盘未受干扰，且宫内妊娠正常进展至足月的情况。
