Abstract: Objective: To compare the effects of transvaginal resection combined with uterine diverticulum neoplasty and uterine artery embolization in the treatment of caesarean scar pregnancy(CSP).Methods: The data of 30 patients with CSP were retrospectively analyzed.Twelve cases were treated with transvaginal resection combined with uterine diverticulum neoplasty,18 cases were treated with uterine artery embolization,methotrexate combined with curettage.The operative time,peroperative bleeding volume,postoperative recovery time of β-hCG,hospitalization time and cost,and complication between two techniques were compared.Results: The differences of the average operation and hospitalization time were not statistically significant(P>0.05).The taking embryo operation through transvaginal resection of lower uterine segment in 12 cases were successful,and no complication was found.The peroperative bleeding volume,postoperative recovery time of β-hCG,hospitalization cost were(55.2±15.5)mL,(15.8±3.5)d and(7 820.5±360.0) Yuan,respectively,which were less than those in the patients treated with uterine artery embolization(P<0.01).Among 18 cases treated with uterine artery embolization,1 case was treated with curettage.The scar broke during the operation,and which was excised and repaired.Conclusions: The treatment of CSP with the transvaginal resection combined with uterine diverticulum neoplasty is effective,safe,economic and quick recovery.
