门静脉-肝静脉瘘的MSCT诊断

MSCT diagnosis of portal-hepatic venous fistula

目的:探讨门静脉-肝静脉瘘多层螺旋CT(MSCT)表现及诊断价值。方法:回顾性分析5例门静脉-肝静脉瘘患者临床及MSCT资料。结果:5例中4例合并肝硬化、门脉高压,肝左叶3例,右叶2例,病变均位于肝包膜下,增强后门脉期与门静脉同步均匀强化,瘤样扩张血管团将门静脉及肝静脉相连通,CPR及VR清晰、直观显示门静脉-肝静脉瘘血管走行及瘘口局部情况。结论:MSCT及三维后处理技术能显示门静脉-肝静脉瘘特征性表现,可作为首选检查方法。

Objective To discuss the diagnostic value of MSCT in the diagnosis of portal-hepatic venous fistula.Method The MSCT findings and clinical data of 5 patients with portal-hepatic venous fistula were analyzed retrospectively.Results 4 cases of portal-hepatic venous fistula with concomitant cirrhosis,hypertension of portal vein showed an aneurianal vessel linked dilated branch of portal vein with hepatic vein,hepatic vein showed in portal venous phase in advance.The abnormal fistulas could be demonstrated vividly with CPR and VR image.Conclusion The whole path and local fistulas vessels of portal-hepatic venous fistula can be described clearly and vividly by post-processing MSCT.MSCT can be used as the primary diagnostic modality to portal-hepatic venous fistula.
