摘　　要：目的探讨超声检查对胎儿脐带血管前置(血管前置)的诊断价值及其临床意义。方法回顾性分析21例血管前置的超声声像图特点,随访胎儿预后。结果 21例血管前置患者(其中脐带帆状附着型16例,副胎盘型4例,双叶胎盘型1例)超声正确诊断17例,准确率80.95%(17/21),漏、误诊4例。典型的图像特征是:彩色多普勒检测见1条血管跨过宫颈内口,频谱多普勒检测血管血流频谱为脐动脉血流频谱。行剖宫产16例,经阴道分娩5例,活婴17例,死婴4例。结论超声检查能直观显示血管前置的走行情况并能判断血管与宫颈内口的方位关系,是诊断血管前置准确的方法,能降低围生儿病死率,有较高的临床应用价值。Objective To explore the value of ultrasonography for the fetal umbilical vasa previa（vasa previa）. Methods The ultrasonographical features of 21 vasa previas were retrospectively analyzed. Results There were 21 cases of vasa previa （including 16 cases of velamentous insertion of umbilical cord, 4 cases of accessory placenta, 1 case of placenta bipartite）. 17 cases were diagnosed by ultrasound and the accuracy was 80.95 % （17/21）. The vasa previa has obvious image features on CDFI：a vessel across the mouth of cervix with umbilical artery blood flow spectrum. Among 21 pregnant women with vasa previa, 16 cases were conducted cesarean birth and 5 cases gave birth by natural labor including 17 living babies and 4 stillbirths. Conclusions Ultrasonography can visualize the traveling of vasa previa and determine the orientation relationship between the vessels and port cervix.
