目的:探讨间接门静脉DSA与多层螺旋CT门静脉造影(SCTP)的门静脉成像差异。方法:收集的40例肝硬化肝癌患者均经肠系膜上动脉或腹腔动脉行间接门静脉DSA和SCTP三维成像,对比分析两种影像质量差异。结果:不同程度肝硬化肝癌的4~5级门静脉显示率SCTP(85%)明显高于间接门静脉DSA(32%),门静脉分支瘤栓显示率间接门静脉DSA(48%)略高于SCTP(16%、40%),门静脉分支推移改变2种方法无差异(均为80%),而动静脉瘘的显示率间接门静脉DSA(85%)要明显优于SCTP(32.5%)。结论:间接门静脉DSA及SCTP检查对门静脉显示各有优势,在临床应用中应根据实际情况选择合理的方法。
Objective: To explore the difference of portal vein imaging between indirect portal vein DSA and multi-slice spiral CT portal venography (SCTP). Methods: Forty patients with hepatocellular carcinoma (HCC) were enrolled in the three-dimensional DSA and SCTP images of the portal vein through the superior mesenteric artery or celiac artery. The differences of the two images were compared. Results: The grade 4 ~ 5 portal vein showed a significantly higher rate of SCTP (85%) than indirect portal vein DSA (32%) in cirrhotic patients with liver cirrhosis. The rate of portal vein thrombosis was slightly higher than that of SCTP (48%) %, 40%). There was no difference between the two methods (all 80%). The rate of arteriovenous fistula was significantly higher than that of indirect portal vein DSA (85%) compared with SCTP (32.5%). Conclusion: Indirect portal vein DSA and SCTP showed superiority in portal vein. In clinical application, reasonable methods should be selected according to the actual situation.
