摘要Objective To analyze retrospectively the utility of uterine arterial embolization(UAE)for cesarean scar pregnancy(CSP).Methods Fifty-one women with CSP were pretreated with UAE before dilatation & curettage(D&C).Indexes such as blood loss volume,operation-associated complications,serum hCG level,ultrasound imaging and hospitalization cost were analyzed.Results Thirty-eight women accepted D&C following UAE(group A),10 patients had medicine(3 took trichosanthin injection,7 took MTX injection)before UAE and D&C(group B).Uterine packing following emergency UAE were performed in another 3 women due to severe hemorrhage during direct curettage without pretreatment (group C).There were no statistically significant differences between group A and group B about the serum β-hCG level resolution time and the blood loss in the opertation.Patients had shorter duration of hospital stay(P＜0.01)and cheaper cost of hospitalization(P＜0.05)of group A than group B.Conclusion Pretreatment with UAE before curettage is safe and effective in terminating CSP,reducing hospitalization cost.UAE followed by curettage is recommended to medical facilities where UAE is available.
