摘　　要：目的:分析彩色多谱勒超声诊断产后胎盘植入血流参数变化及与病情程度关系.方法选择2018年1月-2019年5月本院收治的胎盘植入患者97例为观察组,健康孕妇94例为对照组,采用彩色多普勒超声扫描检查,检测两组孕妇血流指数(FI)、血管化指数(VI)及血管化血流指数(VFI)、血流搏动指数(PI)、阻力指数(RI)、收缩期与舒张期流速比(S/D).采用logistics回归模型分析各指标联合应用的预测模型,采用Spearman相关性检测行相关性检验,采用受试者工作特征(ROC)曲线分析各指标诊断胎盘植入效能.结果:血流参数FI、VI、VFI、PI、RI、S/D水平,观察组均高于对照组且重型胎盘植入患者均高于粘连型胎盘植入患者,各指标水平与粘连型胎盘植入患者的病情严重程度均呈正相关关系(均P<0.05);FI、VI、VFI、PI、RI、S/D联合应用预测胎盘植入的模型为Log(P)=0.603×FI+0.677×VI+0.701×VFI+0.695×PI+0.626×RI+0.633×S/D+1.201,联合检测诊断胎盘植入价值明显提高(P<0.05),其曲线下面积0.974,敏感度96.9%、特异度96.8^%.结论:超声血流参数各指标与胎盘植入病变严重程度呈正相关,且联合检测诊断胎盘植入效能较高.Objective: To analyze the change of ultrasonic blood flow parameters of pregnant women with placental implantation, and to study its correlation with their disease severity. Methods: 97 pregnant women with placental implantation treated were selected in observation group and 94 healthy pregnant women were selected in control group from January 2018 to may 2019. Color Doppler ultrasound was used to measure the blood flow index(FI), vascularization index(VI), vascularization flow index(VFI), blood flow pulsatility index(PI), resistance index(RI), and systolic and diastolic velocity ratio(S/D) of the women in the two groups. The value of the combined FI, VI, VFI, PI, RI, and S/D of the women for predicting their placental implantation was analyzed by logistic regression model. The correlation test was conducted by Spearman correlation detection. Receiver operator characteristic curve(ROC) was used to analyze the diagnostic efficiency of FI, VI, VFI, PI, RI, and S/D of the women for their placental implantation. Results: The values of the blood flow parameters, such as FI, VI, VFI, PI, RI, and S/D, of the women in the observation group were significantly higher than those of the women in the control group, and which of the women with severe placenta accreta were significantly higher than those of the women with adhesive placenta accreta. The values of FI, VI, VFI, PI, RI, and S/D of the women were positively correlated with their severity of the disease(all P< 0.05). The model of value of the combined detection of FI, VI, VFI, PI, RI and S/D of the women for predicting their placenta accreta was Log(P)=0.603×FI+0.677×VI+0.701×VFI+0.695×PI+0.626×RI+0.633×S/D+1.201, and the value of which for diagnosing placenta accreta had increased significantly(P<0.05), with the area under the curve of 0.974,the sensitivity of 96.9%,and the specificity of 96.8%.Conclusion:The values of FI,VI,VFI,PI,RI,and S/D of the women with placental implantation are positively correlated with their severity of the disease,and the combined
