目的 探讨超声对胎儿永存右脐静脉的诊断价值.方法 回顾分析我院诊断的3例胎儿永存右脐静脉的灰阶及彩色多普勒超声表现及相关临床情况.结果 3例胎儿均可见胆囊位于腹部正中,脐静脉连接门脉右支,门静脉窦凹面朝向胃泡.其中1例合并颅内其他异常并在出生后死亡,另2例不合并其他异常,出生半年后生长发育未见异常.结论 胎儿永存右脐静脉具有特征性超声表现,不合并其他畸形时预后良好,早期检出并给予适当的遗传咨询具有重要的临床意义.

Value of ultrasonography in fetuses with persistent right umbilical vein

Objective To investigate the diagnositic value of uhrasonography in fetuses with persistent right umbilical vein.Methods Three cases of persistent right umbilical vein diagnosed in our hospital were analyzed,including the sonographic findings and clinical outcome.Results In all cases the fetal gallbladder was located between the intraabdominal umbilical vein and the stomach,the umbilical vein was connected to the right portal vein,and the portal vein curved toward the stomach.Other intracranial malformations were detected in one case,and the baby died after birth.No addional malformations were found in the other two babies,and both of them were healthy at the age of 6 months.Conclusions Persistent right umbilical vein has typical prenatal sonographic appearances.The neonatal prognosis is favorable when other anomalies are ruled out.It's clinically important for early diagnosis and genetics consultation.
