An application of uterine artery chemoembolization in treating cesarean scar pregnancy.

ObjectiveTo discuss the feasibility and safety of uterine artery chemoembolization in treating cesarean scar pregnancy (CSP).MethodsDuring the period between 1(st) of May 2009 and 17(th) of January 2014, uterine artery chemoembolization with methotrexate (MTX) and gelatin sponge was performed in 31 patients diagnosed with CSP in Xinqiao Hospital. Curettage of uterus was carried out within 24-48 hours after the procedure.ResultsThe success rate of bilateral uterine artery chemoembolization was 100%. The mean blood loss during curettage procedure was only 8.32±4.76 (2-20) ml. The mean time for serum β-HCG normalization was 33.81±17.47 (15-82) days, and the mean time for gestational sacs elimination was 29.52±20.93 (4-90) days. The mean time of hospital stay was 5.10±1.08 (4-8) days.ConclusionsNo serious complications occurred. The uterine artery chemoembolization is an effective and safe treatment for CSP, which greatly reduces the necessity of hysterectomy.
