Abstract:
Objective:To investigate the risk factors and treatments of recurrent cesarean scar pregnancy (RCSP).Methods:A retrospective case-controlled study was performed in 48 cesarean scar pregnancy (CSP) patients in Shenzhen Maternity & Child Healthcare Hospital from January 2014 to December 2018. Recurrent group consisted of 12 patients with RCSP, while control group consisted of 36 patients experienced single CSP. The information of pregnancy, surgery and other factors of the two groups was compared.Results:Thickness of lower uterine segment in recurrent group was thinner than that in control group [(1.81±1.12) mm vs. (2.80±1.56) mm, P=0.031]. Dilation and curettage (D&C) was the main treatment method, and scar repair was the secondary treatment in these two groups. Patients may receive prophylactic uterine artery embolization (UAE) to prevent catastrophic bleeding during surgery when necessary. Totally 11 of 12 patients were cured in recurrent group, while all of 36 patients were cured in control group. Univariate analysis showed that artificial abortions ≥3 times ( P=0.007), type of CSP and thickness of lower uterine segment <3 mm ( P=0.013) had a significant correlation with the RCSP. Conclusion:Artificial abortions ≥3 times and thickness of lower uterine segment <3 mm were the independent risk factors of RCSP. D&C can be used as the first line treatment of RCSP, and prophylactic UAE should be performed when necessary.
