| ［摘要］目的 探讨胎儿永久性右脐静脉（PRUV）的超声诊断及漏诊分析．方法 回顾分析近年来孕中晚期云南省第三人民医院超声检查发现的PRUV胎儿16胎，漏诊3例．结果 永久性右脐静脉胎儿检出率为0.22％（16/7086）．13例为肝内型，5例合并胎儿畸形，3例为肝外型．漏诊3例，其中1例胎儿永久性右脐静脉合并下腔静脉离断漏诊下腔静脉离断，另2例孤立性PRUV漏诊；5例PRuV合并畸形，13例孤立性PRUV预后良好，3例引产．结论 产前超声对胎儿PRUV有较高的诊断价值，但声像图不典型时，易造成漏诊，通过漏诊分析可进一步提高诊断率． |

| Abstract: |
| ［Abstract］Objective To investigate the ultrasonic diagnosis and misdiagnosis of permanent right umbilical vein （PRUV）. Methods We retrospectively analyzed the 16 cases of PRUV diagnosed by ultrasound examination and 3 cases of misdiagnosed PRUV in our hospital in recent years．Results The detection rate of PRUV was 0.22% （16/7086）. 13 cases were intrahepatic type， 5 cases were combined with fetal deformity， 3 cases were ultrahepatic type. There were 3 cases of misdiagnosis， including 1 case of fetal PRUV complicated with broken inferior vena cava， and 2 cases of single PRUV. 5 cases of PRUV were combined with fetal deformities， the prognosis of 13 cases of single PRUV was good， 3 cases received induced labor．Conclusions Prenatal ultrasound examination has higher value in the diagnosis of fetal PRUV， but may cause misdiagnosis when the ultrasonography is not typical. The diagnostic rate may be further improved through the analysis of misdiagnosis. |
