摘　　要：目的探讨经腹部超声(TAS)联合经阴道超声(TVS)检查诊断血管前置的临床应用价值。方法回顾性分析31例产前临床疑诊血管前置孕妇的超声检查及手术病理资料。以手术病理结果为金标准,评价并比较单纯TAS检查与TAS联合TVS检查对血管前置的诊断效能。结果 21例经手术病理证实为血管前置,另10例非血管前置。单纯TAS检查的敏感度、特异度、准确率分别为80.95%(17/21)、63.64%(7/11)及77.42%(24/31);TAS联合TVS检查的敏感度(21/21)、特异度(10/10)及准确率(31/31)均为100%,均高于单纯TAS检查(P均<0.05)。结论 TAS联合TVS检查诊断血管前置较单纯TAS检查可明显提高诊断敏感度、特异度及准确率。Objective To explore the application value of transabdominal sonography（TAS） combined with transvaginal sonography（TVS） in diagnosis of vasa previa.Methods Data of totally 31 pregnant women suspected with vasa previa were retrospectively analyzed.Taking the results of surgical pathology as standard,the diagnostic efficacy of single TAS and TAS combined with TVS in diagnosis of vasa previa were compared.Results There were 21 cases of vasa previa and10 cases of non vasa previa confirmed by operation and pathology.The sensitivity,specificity and accuracy of single TAS was 80.95%（17/21）,63.64%（7/11） and 77.42%（24/31）,respectively.While all of the sensitivity（21/21）,specificity（10/10） and accuracy（31/31） were 100%of TAS combined with TVS,which were higher than those of single TAS（all P〈0.05）.Conclusion Compared with single TAS,TAS combined with TVS,can significantly improve the sensitivity,specificity and accuracy in diagnosis of vasa previa.
