Interstitial/Cornual ectopic pregnancy is a rare condition of pregnancy and may be very dangerous if not identified and treated urgently. We report a case of successful treatment of an interstitial pregnancy using selective uterine artery embolization. A 27–year–old woman with interstitial pregnancy was treated by uterine artery embolization after failure of systemic methotrexate treatment. Her serum beta–human chorionic gonadotropin (β–hCG) was undetectable 10 weeks  after the therapeutic embolization and transvaginal sonography  3 months  after embolization showed normal endometrium and cornu. The patient achieved a normal pregnancy one year  after embolization.
