对比分析肝癌患者间接门静脉DSA与多层螺旋CT门静脉造影三维成像的价值

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。

A comparative study of indirect portography DSA and three-dimensional reconstruction of light speed 16 multiple slice spiral-CT portography

Objective：The features of indirect portography DSA and light speed 16 multiple slice spiral-CT portography（SCTP） in portography imaging were comparatively studied.Methods：40 patients with space occupying diseases of liver accompanied by cirrhosis were examined by indirect portography DSA and 3D-SCTP.Results：In various degrees of liver cirrhosis with portal 4～5 grade,the rate of SCTP（85%） was significantly higher than that by indirect portal vein DSA（16%）,portal vein tumor thrombus showed the rate of indirect branch of portal vein DSA（41%） slightly higher than the SCTP（16%,32%）,portal vein branch showed no difference to change the two kinds of methods（both 80%）,but,the display rate of arteriovenous fistula indirect portal vein DSA（85%） were much higher than SCTP（27%） .Conclusion：This suggests that 3D-SCTP is helpful when the display of portal vein by conventional indirect portography DSA is not very clear.
