Heterotopic (coexistent ectopic and intra-uterine) pregnancy is common following in-vitro fertilization and multiple embryo transfer. Total bilateral salpingectomy is generally considered to eliminate the risk of ectopic, and hence heterotopic pregnancy. This is, however, not strictly correct as it does not eliminate the risk of interstitial tubal pregnancy. This is the first reported case of a heterotopic pregnancy following total bilateral salpingectomy. The diagnostic pitfalls and a suggested method of avoiding them are discussed.
异位（并存的异位妊娠和宫内妊娠）妊娠在体外受精和多胚胎移植后很常见。双侧输卵管全切术通常被认为可消除异位妊娠，从而消除异位妊娠的风险。然而，这并不完全正确，因为它并不能消除输卵管间质部妊娠的风险。这是首例双侧输卵管全切术后发生异位妊娠的报道病例。文中讨论了诊断中的陷阱及一种避免这些陷阱的建议方法。
