A case of successful normal full term delivery after intramural pregnancy excision in heterotypic intramural pregnancy / 대한산부인과학회지

ABSTRACT

Heterotypic pregnancy occurs when there coexist intrauterine and extrauterine (or ectopic) pregnancy and it is very rare. But the incidence of heterotypic pregnancy has been increased due to the rise in pelvic endometriosis, pelvic inflammatory disease (PID), surgery of fallopian tubes and assisted reproductive technologies (ART), such as in vitro fertilization and embryo transfer (IVF-ET). In heterotypic pregnancy, extrauterine gestations are usually implanted in a fallopian tube, ovary, uterine cervix, uterine cornus or peritoneum but rarely in muscle layer of uterus (intramural pregnancy). It is difficult to preserve intrauterine pregnancy because of the risk of uterine rupture after excision of intramural pregnancy. We have experienced a heterotypic intramural pregnancy after IVF-ET which was successfully treated by excision of intramural pregnancy while maintaining the viability of the intrauterine pregnancy. So, we report this case with brief review of literatures.
