Objective To compare the efficacy of uterine artery embolization(UAE)and lauromacrogol injection for cesarean scar pregnancy(CSP)under ultrasound guidance,providing a reference for clinical treatment.Methods A total of 220 CSP patients admitted to the Second People's Hospital of Hengshui between February 2021 and February 2023 were randomly as-signed to a control group(n=110)and an observation group(n=110)using a random number table.The control group un-derwent UAE,while the observation group received lauromacrogol injection under ultrasound guidance.The overall re-sponse rate was assessed one day postoperatively.Intraoperative blood loss,hospital stay,time of operation,time to re-sumption of normal menstruation,and time to postoperative ovulation recovery were compared between the two groups.Additionally,adverse reactions or events during treatment and within one year of follow-up were recorded.Results The o-verall response rate in the observation group was significantly higher than that in the control group[95.45％(105/110)vs.89.09％(98/110);P＜0.05].The observation group demonstrated shorter time to resumption of normal menstruation,and time to postoperative ovulation recovery compared to the control group(P＜0.05).No significant difference was found in adverse reaction rates during treatment between the two groups(P＞0.05).However,the overall adverse reaction rate within one year of follow-up in the observation group was significantly lower than in the control group(P＜0.05).Conclu-sion Compared to UAE,ultrasound-guided lauromacrogol injection for CSP shows superior efficacy,effectively reducing intraoperative blood loss,shortening time of operation and hospital stay,and time to resumption of normal menstruation,and time to postoperative ovulation recovery.Its long-term efficacy is also superior.
