Ultrasound-guided local ethanol injection for fertility-preserving cervical pregnancy accompanied by fetal heartbeat: Two case reports

Abstract

BACKGROUND The incidence of cervical pregnancy is increasing due to the recent widespread application of assisted reproductive technology. Although hysterectomy has been a treatment option, high-sensitivity human chorionic gonadotropin testing and improved accuracy of transvaginal ultrasound imaging have increased possibility of uterine preservation. Dilation and curettage with methotrexate therapy and uterine artery embolization have been reported as treatments with fertility preservation; however, certain disadvantages limit their use. CASE SUMMARY In our two reported cases, we avoided massive bleeding and immediately resumed infertility treatment using ultrasound-guided local ethanol injection for cervical pregnancies with fetal heartbeats. CONCLUSION This treatment may be a new fertility-preserving option for cervical pregnancy.
