摘要
目的:探讨产前超声诊断胎儿静脉导管发育不全的特征和意义。方法:回顾性选取2018年1月-2019年1月笔者所在单位就诊12例胎儿DV发育不全的病历资料,并对其声像图进行分析。结果:本组12例受试对象中,1例为孤立性静脉导管缺失,11例合并其他异常。9例为DVA肝外分流,脐静脉汇入右心房;1例为DVA肝外分流,脐静脉汇入冠状静脉窦;2例为DVA肝内分流,脐静脉连接于门静脉。3例出生后未发现明显异常,6例因合并严重畸形而引产,3例宫内胎儿死亡。结论:产前超声检查能够诊断DV的发育不全,具有重要临床指导意义。
Objective:To explore the characteristics and significance of prenatal ultrasonography in the ductus venosus agenesis.Methods:From January 2018 to January 2019,12 cases of fetal ductus venosus agenesis were retrospectively selected and their sonograms were analyzed.Results:Among the 12 subjects,1 case was isolated ductus venosus absence,and 11 cases were combined with other abnormalities.In 9 cases,DVA was extrahepatic shunt and umbilical vein was connected to the right atrium;1 case was extrahepatic shunt of DVA,and umbilical vein confluence into coronary sinus;2 cases had intrahepatic shunt of DVA,and umbilical vein was connected to portal vein.No obvious abnormality was found in 3 cases,6 cases induced labor due to severe malformation,and 3 cases fetuses died in utero.Conclusion:Prenatal ultrasonography can diagnose DV agenesis,which has important clinical guiding significance.
