肝癌门脉癌栓与肝硬化门脉高压侧支循环的CT研究

Study of CT on the side branch circulation of the hetapo-cellular carcinoma'V.portae canceration and liver cirrhosis'V.portae high pressure

目的:探讨肝细胞癌门静脉癌栓、血管内壁变性与肝硬化、门静脉高压侧支循环形成与临床意义。方法:搜集肝细胞癌门静脉癌栓25例,分成肝硬化组(15例)和无肝硬化组(10例)。选择10例单纯肝硬化门静脉高压作为对照组,观察侧支血管的CT表现。结果:门静脉胆支(胆囊静脉与胆管周围静脉丛)和幽门支(幽门十二指肠静脉和幽门前静脉)是肝细胞癌门静脉癌栓最常显示的血管。肝硬化门静脉高压只有幽门支开放,无胆支开放。结论:研究侧支循环的形成与开放,有利于临床制定治疗方案,具有较高的实用价值。

Objective To explore the form of the side branch circulation and clinical meaning about the hepato-cellular carcinoma＇V.portae canceration and liver cirrhosis＇V, portae high pressure. Methods 25 cases of hepato-cellular carcinoma＇V.portae canceration were divided into liver cirrhosis＇group （15 cases） and non-liver cirrhosis＇group. Compared with 10 cases of liver cirrhosis,the display of CT about the side branch vein was observed. Results The V.cystic of V.portae （the cystic vein and the pericholedochal venous plexus ）and the V.pylorus （the phloricoduodenal vein and the prepylovic vein）were vein being displayed most frequent by the hopatocellular carcinoma＇Vportae canceration; there were no the V.cystic of V.portae but the V.pylorus being open within the liver virrhosis＇V.portae high pressure . Conclusion The study about the form and opening of the side branch circulation of the V.pylorus is in favor of putting forward a plan for treating the hetapo-cellular carcinoma and has a high practical value.
