Successful management of transvaginal reduction in heterotopic interstitial tubal pregnancy: two cases report and literature review

Abstract

Objective To investigate the treatment of heterotopic pregnancy (HP) after in vitro fertilization and embryo transfer (IVF-ET), and to explore the effect of clinical treatment of transvaginal ultrasound-guided embryo aspiration at the early stage of pregnancy. Methods Two successful cases of heterotopic interstitial tubal pregnancy treated with transvaginal ultrasound-guided ectopic embryo aspiration in early pregnancy and relevant literature review were discussed. Results After the treatment of transvaginal ultrasound-guided embryo aspiration in the early diagnosed interstitial tubal pregnancy with cardiac activity, the retained intrauterine fetal continues to be pregnant and a healthy baby will be delivered at term. Conclusion Transvaginal ultrasound-guided embryo aspiration can be considered to be a management of heterotopic interstitial tubal pregnancy in the first trimester. However, the follow-up is important because of the potential in the growth of retained villi tissue.
