Two women were treated for heterotopic pregnancies, the simultaneous occurrence of an intrauterine pregnancy and an ectopic pregnancy. The commonly accepted incidence is 1:30,000. The actual rate appears to be significantly higher; the two most prominent reasons are today's increased rate of ectopic pregnancies and the increased use of clomiphene in infertile women. A rigorous evaluation is required in all early pregnancies in which an ectopic is suspected to rule out the presence of a heterotopic pregnancy.
两名女性接受了异位妊娠的治疗，即子宫内妊娠和异位妊娠同时发生。普遍认可的发病率为1:30000。实际发生率似乎要高得多；两个最主要的原因是如今异位妊娠率的上升以及不孕女性中克罗米芬使用的增加。对于所有疑似异位妊娠的早期妊娠，都需要进行严格评估，以排除异位妊娠的存在。
