A Case of Heterotopic Pregnancy / 대한산부인과학회잡지

ABSTRACT

Heterotopic pregnancy, simultaneous intrauterine and extrauterine gestations, is a relatively rare condition with an estimated incidence of 1 in 30,000 pregnancies. The incidence of heterotopic pregnancies have increased in recent years because of rising incidence of pelvic inflammatory disease, pelvic surgery, expanding use of assisted reproductive technology. Common sites of extrauterine gestation are salpinx, cornus and cervix of uterus, ovary, and abdomen in order of incidence. Early detection of heterotopic pregnancy is very difficult and is often more difficult in the case of abdominal pregnancy. However, to avoid high maternal morbidity, mortality, and loss of pregnancy, one should always take this into consideration and should conduct careful and thorough gynecologic evaluations. We have experienced a case of abdominal pregnancy following termination of intrauterine pregnancy in a 23-year-old unmarried woman and report it with brief review of literatures.
