摘　　要：目的探讨产前超声图像特征联合胎盘植入高危因素评分对胎盘植入的预测价值。方法选择120例产后确诊为前置胎盘的患者为研究对象,以剖宫产手术情况或病理检查结果为诊断金标准,将其分为正常、粘连组(n=77,包括正常前置胎盘不伴植入52例和粘连型胎盘25例)和植入组(n=43,包括植入型胎盘38例和穿透型胎盘5例)。分析2组临床资料和典型超声图像特征,建立超声图像特征和胎盘植入高危因素联合评分预测模型。采用受试者工作特征(ROC)曲线分析2组评分量表的诊断界值,并计算诊断灵敏度及特异度、阳性及阴性预测值。结果联合评分的诊断界值为5分,诊断灵敏度为81.4%,特异度为94.8%,阳性及阴性预测值各为89.7%、90.1%。结论联合评分预测模型在胎盘植入诊断中具有较高的价值。Objective To investigate the predictive value of prenatal ultrasonic graphic features combined with high risk factor score for placental implantation.Methods A total of 120 patients confirmed as postpartum placenta previa were selected as study objects,and were divided into normal and adhesion group(n=77,normal placenta previa without implantation in 52 cases,adhesion placenta implantation in 25 cases)and implantation group(n=43,implantation placenta in 38 cases,penetration placenta implantation in 5 cases)according to caesarean section operation or pathological results as the diagnostic gold standard.Clinical data and typical ultrasonographic features of patients in the two groups were analyzed,and ultrasonographic feature combined with placental implantation risk factor score model was developed.Receiver Operating Characteristics(ROC)curve was used to analyze the diagnostic threshold values of the scale in the two groups,and the diagnostic sensitivity and specificity,positive and negative predictive values were calculated.Results The boundary value of combined score scored 5.The diagnostic sensitivity and specificity were 81.4%,94.8%,respectively,and the positive and negative predictive values were 89.7%and 90.1%,respectively.Conclusion The combined scoring predictive model has high practical value in the diagnosis of placenta implantation.
