A pregnancy located within a cesarean scar is the rarest form of ectopic pregnancy. We present a case of a 34-year-old woman with a history of one cesarean section (gravida 2, para 1) admitted to the hospital at 9 weeks of gestation due to vaginal bleeding, initially diagnosed as a missed abortion. During the hospitalization spontaneous abortion took place, and the patient was qualified for dilatation and curettage. After the procedure massive vaginal bleeding occurred, a cesarean scar pregnancy was diagnosed, and uterine artery embolization (UAE) using gelatin sponge particles was performed. The treatment was successful. Our case shows that UAE might be a life-saving procedure in cesarean scar pregnancy hemorrhages. Absorbable properties of gelatin sponge particles reduce the risk of adverse effect on fertility.
