Hysteroscopic management of cesarean scar pregnancy after unsuccessful methotrexate treatment.

Current management of cesarean scar pregnancy is conservative and consists of medical treatment with methotrexate (MTX). We present a report on a woman with this type of pregnancy who had continuous vaginal bleeding and persistent serum levels of beta human chorionic gonadotropin after undergoing curettage and MTX. Eventually, the remaining ectopic gestational tissue was removed by operative hysteroscopy.
