胎儿脐静脉异常的超声诊断

目的 探讨胎儿脐静脉异常的超声表现及其诊断问题.方法 结合产前超声检查发现的胎儿脐静脉异常14例,对其结果进行总结分析.结果 本组14例胎儿脐静脉异常中,6例胎儿脐静脉扩张和5例永存性右脐静脉超声表现典型,诊断明确,3例脐静脉破裂,缺乏特征性表现,超声检查未能作出诊断.6例脐静脉扩张,超声表现为胎儿腹内段脐静脉管径增宽,在1.0～2.0 cm之间,其中弥漫性扩张4例,瘤样扩张2例;5例永存性右脐静脉,超声表现为脐静脉进入肝脏以后,转向左侧,位于胆囊的右侧;3例脐静脉破裂,超声仅显示帆状胎盘、前置血管、羊水混浊等.结论 超声检查对脐静脉扩张和永存性右脐静脉能作出明确诊断,脐静脉破裂诊断困难,但是可以发现一些有助于诊断的信息.超声检查对于发现胎儿脐静脉异常具有重要的价值.
