Abstract: Heterotopic pregnancy is rare in clinic and in recent years, with the rise of assisted reproductive technology, the incidence has risen. Its clinical manifestations are different, mainly depending on the development of ectopic pregnancy lesions implanted outside the uterine cavity. The mild cases have no obvious symptoms or signs, and the severe cases may cause abdominal hemorrhage, hemorrhagic shock or even death. As heterotopic pregnancy is very dangerous, clinical diagnosis should be made as soon as possible and individualized treatment should be taken to ensure the safety of mothers and children. In order to take the attention of gynecologists and obstetricians, now we report a case of early intrauterine pregnancy complicated with left tubal umbrella pregnancy and consult the relevant literature, summarize the knowledge of heterotopic pregnancy.
