Necessity of prophylactic uterine artery embolization before curettage in treatment of cesarean scar pregnancy / 中国介入影像与治疗学

ABSTRACT

Objective To evaluate the necessity of prophylactic uterine artery embolization (UAE) before curettage in treatment of cesarean scar pregnancy (CSP).Methods A total of 142 patients with CSP were enrolled and divided into 3 groups according to Adler grading standard,including little vascularity (grade 0-Ⅰ,n=40),moderate vascularity (grade Ⅱ,n=41) and rich vascularity groups (grade Ⅲ,n=61).All patients were treated with curettage or prophylactic UAE before curettage.The differences of age,times of cesarean section,time to last cesarean section,intraoperative blood loss and success rate of therapy were compared between different treatment methods in each group.Results There was no statistical difference of age,times of cesarean section,time to last cesarean section,intraoperative blood loss and success rate of therapy between curettage and prophylactic UAE before curettage in little vascularity group and moderate vascularity group (all P＞0.05).Compared with curettage,the success rate of prophylactic UAE before curettage was higher and the intraoperative blood loss was lower in rich vascularity group (both P＜0.05).There was no statistical difference of age,times of cesarean section nor time to last cesarean section in rich vascularity group (all P＞0.05).Conclusion It is necessary to perform prophylactic UAE before curettage for cesarean scar pregnancy patient with rich vascularity,which is helpful to reduction of intraoperative blood loss.
