摘要
目的探讨门静脉CT血管成像(PVCTA)在诊断门静脉瘤(portal vein aneurysm,PVA)中的价值。资料与方法回顾性分析3例PVA的临床与CTA资料,并复习相关文献。结果PVCTA清晰显示3例PVA的发生部位、扩张程度及与邻近结构的解剖学关系。3例均位于肝门或肝内门静脉分支交汇处,2例病变呈囊状,1例病变局部一致性扩张。3例均无相应临床表现及基础病变。文献报道18例中13例位于肝内门静脉分支交汇处,4例位于脾静脉与肠系膜上静脉交汇处,1例位于门静脉主干。18例中5例有肝癌伴肝硬化,其余无临床表现(6例)或仅有腹痛或腹部不适(7例)。结论PVA好发于肝内或肝外门静脉交汇处,多无基础疾病,PVCTA能够清楚显示PVA的部位、大小、形态、有无血栓、瘤体与邻近结构的空间关系。
Objective To explore the value of CT angiography for portal vein aneurysm（PVA）.Materials and Methods The clinical information and PVCTA findings of 3 cases with portal vein aneurysm were retrospectively analyzed,and then relative literatures were reviewed.Results In all 3 cases,the location,size,as well as anatomic ralationship with surrounding structures were displayed well on PVCTA images.All aneurysms involved the juncture of portal vein in intrahepatic or portal region.The anurysms had the shape of cystic or segmental dilatation in 2 and 1 case respectively.No corresponding clinical manifestation and underlying disease were found.Among the 18 cases reported in the literatures,13 were located at the junction of introhepatic branches of portal vein,4 at the junction of spleen vein and superior mesentery vein,and only 1 case located in the main stem of portal vein.5 of 18 cases had hepatocellular carcinoma and cirrhosis,while others had not any symptoms（6 cases） or merely with slight abdominal pain（7 cases）.Conclusion PVA is commonly located at the juncture of of intra-or extrahepatical portal vein.PVCTA could accurately display the location,size,morphology,thrombus,and the relationship anatomy of PVA.
