A Case of Heterotropic Pregnancy After In Vitro Fertilization / 대한산부인과학회잡지

ABSTRACT

Heterotropic pregnancy is defined as coexistent intrauterine and ectopic pregnancy. The natural incidence is 1 per 30,000 pregnancies, but in case of ovulation induction and in vitro fertilization, it is 1 per 100 pregnancies. Heterotropic pregnancy is increased with pelvic inflammatory disease and the use of various ovulation induction method. Because heterotropic pregnancy is clinically difficult to early diagnosis, close monitoring of pregnancy is important to prevent a deleterious delay in the treatment of ectopic pregnancy, maternal morbidity, and fetal loss. We experienced a case of heterotropic pregnancy diagnosed by ultrasonography in a 32-year-old woman, who complained of vaginal spotting and low abdominal pain after in vitro fertilization and report the case with brief review of literature.
