Abstract：Objective To explore the contraceptive efficacy and safety of compound short-acting oral contraceptives,levonorgestrel releasing intrauterine system and condoms after cesarean scar pregnancy curettage.Methods From August 2014 to August 2016,121 patients with cesarean scar pregnancy were randomized into three groups.39 patients in the contraceptive pill group were treated with compound short-acting contraceptives,39 patients in mirena group were placed Mirena (levonorgestrel-releasing intrauterine system)after curettage immediately,and 43 patients in condom group were given condoms contraception.Patients of three groups were followed up to compare ultrasonic examination results,unexpected pregnancy and menstrual flow change.Results Patients were followed up for 12 months.The total effective rates of patients in contraceptive pill group was 97.4%,there was 1 case of recurrent CSP in contraceptive pills group because of forget to take the pills.The total effective rates of patients in Mirena patient group was 100%.The total effective rates of patients in condoms contraception group was 91%.There was 4 pregnancy occurred,including 1 case of recurrent CSP and 3 case of intrauterine pregnancy.The total effective rates of patients in contraceptive pill group and Mirena patient group were significantly higher than patients in condoms contraception group,and the difference was statistically significant(P＜0.05).Ultrasonic examination showed there were no incision rupture or damage and no complaints about asexual life in the 3 groups.There was no increase in the amount of menstruation in the three groups and the decrease of menstruation in the patients of Mirena group was significantly higher than that of the condom group and the contraceptive pill group at 3,6 and 12 months postoperatively,with significant difference (P＜0.05).ConclusionAfter uterine artery embolization combined with uterine curettage cesarean scar pregnancy patients can take marvelon and Mirena intrauterine contraception,which is safe,reliable,and can benefit patients more,and is better than only using condoms.
