摘　　要：目的:探讨早孕期子宫动脉血流参数和瘢痕部位血管化参数诊断瘢痕妊娠(CSP)的价值。方法:回顾性收集本院2017年6月—2021年6月就诊的剖宫产史早孕CSP孕妇(≤12周)82例为CSP组,非CSP 114例为非CSP组,阴式分娩史早孕妇女74例为对照组;阴道彩色多普勒超声检测3组子宫动脉血流参数,包括搏动指数(PI)、子宫动脉阻力指数(RI)、收缩期峰值流速/舒张末期流速(S/D);转换三维能量多普勒超声模式,结合Vocal软件检测瘢痕部位血管化参数,包括血管化指数(VI)、血流指数(FI)和血管化血流指数(VFI);运用受试者工作曲线分析瘢痕血管化参数诊断CSP价值。结果:3组子宫动脉血流参数RI有差异,CSP组与对照组S/D有差异,CSP组和非CSP组瘢痕部位血管化参数VI、FI和VFI有差异(均P<0.05)。VI、FI、VFI诊断CSP的曲线下面积(AUC)分别为0.768、0.795、0.805,检测临界值分别为8.49、20.93和2.27。结论:早孕期子宫动脉RI、S/D在不同分娩史孕妇中存在差异,三维能量多普勒超声VI、FI、VFI对剖宫产史发生CSP有一定诊断价值。临床可根据临界值定量分析,以提高CSP的早期诊断准确性。Objective:To investigate the diagnostic value of blood flow parameters of uterine artery and vascularization parameters of scar site for cesarean scar pregnancy(CSP)of women during the first trimester of pregnancy.Methods:82 women with CSP during the first trimester of pregnancy(≤12 gestational weeks)who had caesarean section history from June 2018 to June 2020 were selected in group A retrospectively,114 normal pregnant who had caesarean section history during the first trimester of pregnancy were selected in group B,and 74 normal pregnant women with vaginal delivery history and without caesarean section history were selected in group C.The values of uterine artery blood flow parameters,such as pulsatility index(PI),uterine artery resistance index(RI),peak systolic velocity/end diastolic velocity(S/D),of the women in the three groups were examined by transvaginal color Doppler ultrasound.The vascularization parameters of scar site,such as vascularization index(VI),blood flow index(FI),and vascularization flow index(VFI),of the women in the three groups were examined by the three-dimensional energy Doppler ultrasound mode combined with Vocal software.Receiver operator characteristic(ROC)curve was used to analyze the diagnostic value of the vascularization parameters of scar site for CSP.Results:There was significant difference in the RI value of the uterine artery blood flow parameters of the women among the three groups,and there was significant difference in the S/D value of the uterine artery blood flow parameters of the women between group A and group C.There were significant differences in the values of VI,FI,and VFI of vascularization parameters of scar site of the women between group A and group B(all P<0.05).The area under the curve(AUC)of the VI value,the FI value,and the VFI value of the women for diagnosing CSP was 0.768,0.795,and 0.805,respectively,and the detection critical value of which were8.49,20.93,and 2.27,respectively.Conclusion:The values of RI and S/D of uterine artery of the pregnant wome
