【摘要】 内镜治疗方法是目前处理肝硬化门脉高压引起的食管胃底静脉曲张重要的手段。然而,静脉曲张存在不同的分流特征可影响治疗方法的选择及预后的效果。回顾性分析肝硬化门脉高压患者CT门静脉成像特点,测量门静脉主干及脾静脉、胃左静脉、肠系膜上静脉等主要分支管径,记录门脉侧支循环开放的具体位置、曲张程度及数量,比较CT成像结果与胃镜分型特点,并进行统计学和临床分析。多层螺旋CT门静脉成像(CTPV)可以清晰显示门脉系统和侧支血管,并可详细了解分流的解剖学特征,准确确定分流类型,对于血管管径的测量也具有很好的准确性。CTPV检查对于食管胃底静脉曲张治疗方法选择、用药剂量以及预后评估有较大临床意义。更多还原

【Abstract】 Endoscopic therapy is the mainstream to treat esophagofundal varices due to portal hypertension in liver cirrhosis.However,varices usually present with distinctive characteristics of shunts which may affect the treatment choice.By means of CT portal venograpy(CTPV),the diameter of portal vein and its major intrahepatic branches,as well as the distribution and extent of collateral circulations were recorded.CTPV can accurately show the courser and the distribution of the major branches,measure the diameter of the blood vessels and construct the stereo-spatial configuration on portal vein system.Importantly,it offers more evidence for variceal bleeding evaluation and benefits endoscopic individualized treatment in cirrhotic patients.更多还原
