An active obstetric service can expect to have one perinatal death each year due to vasa previa. Unfortunately, little has been done to improve the diagnosis and treatment of this condition, which presents no risk to the mother but is often fatal to the fetus. The various clinical pictures which can be associated with vasa previa are presented, along with a discussion of the techniques readily available for making the diagnosis: palpation and visualization, amnioscopy, fetal heart monitoring, and various tests for the presence of fetal hemoglobin.
一个活跃的产科服务机构每年可能会有一例因前置血管导致的围产期死亡。不幸的是，在改善这种情况的诊断和治疗方面几乎没有采取什么措施，这种情况对母亲没有风险，但对胎儿往往是致命的。文中介绍了与前置血管相关的各种临床表现，同时讨论了现有的诊断技术：触诊和可视化、羊膜镜检查、胎儿心率监测以及检测胎儿血红蛋白的各种测试。
