본원 산부인과에서는 과거 8년간 병합임신 2례를 경험하였는 바, 그중 1예는 파열형 난관임신으로 우측 난관임신 수술후에야 병합임신이 진단되어 임신만삭까지 지속 정상 분만한 경우이고, 다른 1예는 파열형 좌측 난관임신으로 좌측 난관절제술과 동시에 영구피임 목적으로 우측 난관절제술을 시행한 환자에서 수술후 정기진찰시 병합임신으로 진단된 경우이다.

Combined intrauterine and extrauterine pregnancy refers to impregnation of the ectopic and uterine ova within a short time of each other and is an uncommen clinical entity. Its incidence is approximately 1 in 30,000 pregnancies. The preoperative diagnosis of simultaneous intrauterine and extrauterine pregnancy is rarely made. Frequently the intrauterine pregnancy is not recognized even at the time of operation since it is known that a certain degree of uterine enlargement occurs in ectopic pregnancy alone. Two cases of heterotopic pregnancy which we have experienced in our hospital from December 16, 1971 to December 15, 1980 are presented, with a brief review of the literatures.
