【摘要】 目的探讨胎儿胆道异常的产前超声表现。方法1995至2005年,采用常规超声对40000例来我院行产前检查的中晚期孕妇行胎儿胆道异常筛查,对部分胎儿胆道异常病例行三维超声重建,并对胎儿胆道异常者行产前及产后随访。结果本组共检出31例胆道异常胎儿,其中胆总管囊肿2例,胆囊内强回声29例。在29例胆囊内强回声胎儿中,27例胆囊内强回声具有胆囊结石的声像表现,2例类似胆囊内浓缩胆汁的声像表现,除3例失访外,余26例胆囊内强回声均在产前及产后随访中消失。结论超声检查能较好地显示胎儿胆道异常,并能动态监测其转归,是诊断胎儿胆道异常的首选方法。更多还原

【Abstract】 Objective To discuss the diagnostic value and clinical meaning of prenatal ultrasound for fetal biliary tract disease diagnosis. Methods 2 DUS and 3 DUS were scanned to examine the fetal biliary tract in 40 000 pregnant women in middle or late pregnancy. Results There were 31 fetuses with biliary tract diseases were checked. Two cases had choledochal cyst and 29 fetuses had strong echoes inside the gallbladder. Among the 29 fetuses, 27 had strong echoes with cholelithic features and 2 with concentrated bile. Except 3 ones lost follow up, the remaining fetuses with strong echoes in the gallbladder were all disappeared in prenatal or postnatal. Conclusions Ultrasound can not only clearly display the fetal biliary system diseases, but also can show dynamic changes. It is a promised method for diagnosing fetal biliary diseases.更多还原
