摘　　要：目的探讨超声造影在瘢痕妊娠患者治疗中的指导价值及对血流动力学的影响。方法选取2017年1月~2019年12月在我院超声检查的有剖宫产史再次妊娠并拟终止妊娠的早孕妇女116例作为研究对象,所有孕妇均接受常规超声检查与超声造影检查,将后期人工流产术中检查的结果作为金标准。比较最终诊断结果、两种诊断方法特异度、敏感度、阴性预测值、阳性预测值、约登指数、分析正常宫内妊娠、瘢痕妊娠孕妇的血流动力学特征情况。结果常规超声检出正常宫内妊娠孕妇70例,瘢痕妊娠孕妇30例,漏诊10例,误诊6例,常规超声检出率为86.2%;超声造影检查检出正常宫内妊娠孕妇80例,瘢痕妊娠孕妇36例,漏诊、误诊率为0,超声造影检出率为100.0%,因此,超声造影检查检出率高于常规超声检查(P<0.05);将后期人工流产术中检查的结果作为金标准,其中正常宫内妊娠孕妇80例,妊娠瘢痕孕妇36例,常规超声检出正常宫内妊娠孕妇70例,瘢痕妊娠孕妇30例,漏诊10例,误诊6例,超声造影检查检出正常宫内妊娠孕妇80例,瘢痕妊娠孕妇36例,漏诊、误诊率为0,超声造影检查特异度、敏感度、阴性预测值、阳性预测值、约登指数高于常规超声检查(P<0.05);瘢痕妊娠孕妇PST、PIT、SLPT、AUC低于正常宫内妊娠孕妇(P<0.05)。结论瘢痕妊娠患者诊断中,超声造影的诊断结果准确,可为临床治疗提供一定的指导价值,值得临床应用。Objective To explore the guiding value of contrast-enhanced ultrasound in the treatment of the patients with scar pregnancy and its influence on hemodynamics.Methods From January 2017 to December 2019,116 early pregnant women with a history of cesarean section who were pregnant again,intended to terminate their pregnancy and had ultrasound examination in our hospital were selected as the subjects of research.All the pregnant women received conventional ultrasound examination and contrast-enhanced ultrasound examination,and the results of intraoperative examination in late abortion were taken as the gold standard.The final diagnosis results,the specificity,sensitivity,negative predictive value,positive predictive value and jordan indexes of the two diagnostic methods were compared,and the hemodynamic characteristics of the pregnant women with normal intrauterine pregnancy and scar pregnancy were analyzed.Results 70 cases of normal intrauterine pregnancy and 30 cases of scar pregnancy were detected by conventional ultrasound,with 10 cases of missed diagnosis and 6 cases of misdiagnosis,and the detection rate of conventional ultrasound was 86.2%.80 cases of normal intrauterine pregnancy and 36 cases of scar pregnancy were detected by contrast-enhanced ultrasound,with the rate of missed diagnosis and misdiagnosis being 0,and the detection rate of contrast-enhanced ultrasound was 100.0%.Therefore,the detection rate of contrast-enhanced ultrasound examination was higher than that of conventional ultrasound examination(P<0.05).When the results of intraoperative examination in late abortion were taken as the gold standard,there were 80 cases of normal intrauterine pregnancy and 36 cases of scar pregnancy.Since 70 cases of normal intrauterine pregnancy and 30 cases of scar pregnancy were detected by conventional ultrasound,with 10 cases of missed diagnosis and 6 cases of misdiagnosis,while 80 cases of normal intrauterine pregnancy and 36 cases of scar pregnancy were detected by contrast-enhanced ultrasound,with the rate o
