While scattered reports of its use for postpartum hemorrhage exist, no indications have been described. We report a case of hysteroscopic resection of retained products of conception using uterine artery balloon occlusion instead of uterine artery embolization. A 29-year-old woman, gravida 2 para 0, noted an intrauterine mass after an abortion at 7 weeks' gestation. Follow-up visits showed insufficient lowering of human chorionic gonadotropin levels, necessitating surgical treatment. Considering the patient's desire to conceive, we performed uterine artery balloon occlusion to reduce the risk of perinatal complications associated with uterine artery embolization. The operation was completed without complications. The patient conceived spontaneously and had a live baby 7 months after surgery, thus proving the benefits of uterine artery balloon occlusion before hysteroscopic resection.
