Management of a uterine serosal heterotopic pregnancy after in vitro fertilization in a woman with bilateral salpingectomy: A case report and literature review.

Rationale: Heterotopic pregnancy (HP) is defined as the simultaneous presence of intrauterine pregnancy and ectopic pregnancy (EP). HP after bilateral salpingectomy is extremely rare and may lead to serious complications if it is misdiagnosed and untreated timely. Here, we presented the first reported case of uterine serosal HP in a woman after assisted reproductive technology with bilateral salpingectomy because of bilateral tubal ectopic pregnancy.
