本研究的目的是评价经腹彩色多普勒超声（TA-CDUS）和经阴道彩色多普勒超声（TV-CDUS）作为孕妇前置血管（VP）和脐带脱垂（VCI）筛查方法的可行性和准确性。 对2018年至2021年期间接受TA-CDUS和TV-CDUS检查的5，434名孕妇进行了回顾性诊断准确性研究。TA-CDUS和TV-CDUS的诊断性能通过特异性、阳性预测值（PPV）、阴性预测值（NPV）、准确性以及阳性和阴性似然比（LR+和LR-）来确定，并使用交付信息（大体检查）作为“金标准”。审查患者记录的人口统计学和诊断。 在37/5434（0.68%）名分娩妇女中诊断出VP和VCI的组合。TA-CDUS诊断VP伴VCI的敏感性、特异性、PPV、NPV和总体检测准确性分别为72.97%、99.85%、77.14%、99.81%和99.67%。TV-CDUS的相应值分别为89.19%、99.87%、82.50%、99.93%和99.80%。TA-CDUS与TA-CDUS联合诊断VP伴VCI的敏感性为97.30%，特异性为99.98%，阳性预测值为97.30%，阴性预测值为99.98%，准确性为99.96%。TA-CDUS与TV-CDUS在误诊和漏诊方面无显著性差异。 TA-CDUS和TV-CDUS均可以作为评价VP和VCI孕妇的诊断工具，TV-CDUS的应用更好，准确性更高。TA-CDUS和TV-CDUS联合应用可为临床治疗方案的选择和预后判断提供客观的影像学依据。
The objective of this study is to evaluate feasibility and accuracy of transabdominal color Doppler ultrasound (TA-CDUS) and transvaginal color Doppler ultrasound (TV-CDUS) as screening methods for pregnant women with vasa previa (VP) and velamentous cord insertion (VCI). A retrospective diagnostic accuracy study was performed on 5,434 pregnant women from 2018 to 2021, who underwent both TA-CDUS and TV-CDUS. Diagnostic performance of TA-CDUS and TV-CDUS was determined using specificity, positive predictive value (PPV), negative predictive value (NPV), accuracy, and positive and negative likelihood ratios (LR+ and LR−), using the delivery information (gross examination) as the “Gold-standard”. Patient records were reviewed for demographics and diagnosis. The combination of VP and VCI was diagnosed in 37/5434 (0.68%) women at delivery. The sensitivity, specificity, PPV, NPV, and overall test accuracy of TA-CDUS were 72.97%, 99.85%, 77.14%, 99.81%, and 99.67%, respectively, for diagnosing VP with VCI. The corresponding values for TV-CDUS were 89.19%, 99.87%, 82.50%, 99.93%, and 99.80%, respectively. Moreover, the sensitivity of combination of TA-CDUS and TA-CDUS in determining VP with VCI was 97.30%, specificity 99.98%, PPV 97.30%, NPV 99.98%, and accuracy 99.96%. No significant difference in the misdiagnosis and missed diagnosis was found between the examination by TA-CDUS and TV-CDUS. Both TA-CDUS and TV-CDUS can be acceptable diagnostic tools for assessment of pregnant women with VP and VCI, with a better application of TV-CDUS with higher accuracy. The combination of TA-CDUS and TV-CDUS could provide an objective imaging basis for choosing clinical treatment strategies and predicting prognosis.
