Medical abortion with misoprostol has become one of the safest techniques for terminating early intrauterine pregnancy. However, massive uterine bleeding can occasionally occur. Here, we describe a woman with a 7-week intrauterine pregnancy who underwent medical abortion with vaginal misoprostol. Subsequently, she developed excessive uterine bleeding and severe anemia. Uterine curettage was used to remove residual placenta debris, but caused massive uterine bleeding. Insertion of a Foley catheter with inflation of 30 mL water into the balloon successfully controlled the massive uterine hemorrhage.
