摘要
目的:探讨多层螺旋CT血管成像(MSCTA)在诊断外生性肝细胞肝癌(EHCC)中的价值。方法:回顾性分析经手术病理证实的23例EHCC患者的病例资料,采用容积再现重组血管生长技术(AV)进行血管重组,显示肿瘤供血动脉,并与手术结果进行比较,评价其在肿瘤定位及周围器官侵犯诊断中的准确性。结果:23例25个EHCC最大径6.5～17.5cm,平均10.8cm。肿瘤与肝脏以蒂带连接2处,基底连接23处,起源于肝右叶及尾状叶者(12个)由肝右动脉分支供血,左叶者(11个)主要由肝左动脉供血,MSCTA定位诊断符合率100%(25/25)。肿瘤侵犯周围器官4例5处,MSCTA仅显示3处侧支供血动脉。结论:MSCTA通过显示EHCC供血动脉,能准确进行定位诊断,对判断周围器官的侵犯亦有较高的价值。
Objective：To evaluate the diagnostic value of MSCTA for extrahepatic hepatocellular carcinoma（EHCC）.Methods：23 patients of EHCC with surgical and pathological confirmation were analyzed retrospectively.Their MSCT angiographies with volume rendering arterial reformation（add vessel）technique could delineate the feeding artery of tumors and then the correlative study was taken with surgical results for determination of accurcy for tumor localization and vicinity invasion.Results：25 tumors 23 patients,included 2 with pediculas and the other 23 with basal attachment to the liver;and the maximum diameter was 6.5～17.5cm（mean 10.8cm）.Feeding artery originated from the branch of right hepatic artery（RHA）supplied the tumors in the right or/and caudate lobe of liver;wheras the tumors in the left lobe were fed by left hepatic artery（LHA）.The localization sensitivity with MSCTA reached 100%（25/25）.Five tumor invasions of the adjacent organs were demmstrated in 4 cases,but only 3 collateral feeding arteries were shown on MSCTA.Conclusion：MSCTA can make accurate localization for EHCC due to opacification of the tumor feeding artery,and furthermore provide rather high value in diagnosing invasion to the adjacent organs.
