Heterotropic pregnancy: Rare occurrence of a 12- week ruptured right isthmo-cornual ectopic along with a viable intrauterine pregnancy

摘要

Heterotropic pregnancy, although a rare condition, is associated with a greater frequency in assisted reproduction. It occurs in approximately 1 in 100 pregnancies conceived by in vitro fertilization (IVF) particularly when multiple embryos are transferred into the uterus. We report a case of heterotropic pregnancy following IVF with the rupture of an isthmo-cornual pregnancy at 12 weeks of gestation with uneventful progression of the intrauterine pregnancy. Laparotomy was performed for the excision of the isthmo-cornual pregnancy. The intrauterine pregnancy continued uneventfully. A female baby was delivered by elective cesarean section at 33 weeks.KEY WORDS: Cornual, heterotropic pregnancy, intrauterine pregnancy, isthmus, laparotomy, rupture
