Ultrasound and Doppler imaging have proven to be valuable antepartum diagnostic tools for the early recognition of vasa previa. Recent reports have demonstrated that successful detection and timely management can subsequently reduce the risk of a life-threatening fetal hemorrhage. We present the fourth reported case of vasa previa detected antenatally by ultrasound. While conscientious attention to the risk factors and a high index of clinical suspicion remain important considerations, we believe that ultrasound and color Doppler flow analysis represent a highly sensitive diagnostic tool for those patients at risk. In the past, antenatal diagnosis has relied on insensitive and inconclusive means, often only after signs of fetal compromise have become apparent. Sonography has been demonstrated to offer reduced fetal mortality and therefore must be considered the new standard of care for management of suspected vasa previa.
超声和多普勒成像已被证明是用于产前早期识别前置血管的有价值的诊断工具。最近的报告表明，成功检测并及时处理随后可降低危及生命的胎儿出血风险。我们报告了第四例经超声产前检测出前置血管的病例。尽管认真关注危险因素和保持高度的临床怀疑仍然是重要的考虑因素，但我们认为超声和彩色多普勒血流分析对于那些有风险的患者而言是一种高度敏感的诊断工具。过去，产前诊断依赖于不敏感且不确定的方法，通常只有在胎儿窘迫迹象明显后才进行诊断。超声检查已被证明可降低胎儿死亡率，因此必须被视为疑似前置血管管理的新护理标准。
