Successful transvaginal ultrasound-guided ablation of a cervical pregnancy in a patient with simultaneous intrauterine pregnancy after in vitro fertilization and embryo transfer

Abstract

Heterotopic pregnancy, or simultaneous intrauterine and extrauterine gestation, is a relatively rare condition. However, induced ovulation and assisted reproductive technologies have markedly increased the incidence of this condition. In this article, a case of heterotopic pregnancy after in vitro fertilization and embryo transfer is presented in which the viable cervical pregnancy was treated by transvaginal ultrasound-guided puncture and injection of potassium chloride in conjunction with methotrexate at week 6 of gestation. At week 12 of gestation, the intrauterine gestation was viable and complete resorption of the cervical pregnancy had occurred. At week 30 of gestation, a healthy baby was delivered by Caesarian section after prelabour rupture of membranes.
