【摘要】 目的评价螺旋CT门静脉造影(SCTA)对评估肝硬化门静脉高压侧支循环的作用。方法收集肝硬化患者36例,使用美国GELightSpeed4排螺旋CT行SCTA造影术,观察门静脉系统病变程度与肝硬化Child分级的相关性。结果造影发现门静脉及其属支的管径明显扩张,其中胃冠状静脉曲张31例(86.1%)、食管胃底静脉曲张27例(75.0%)、食管周围静脉曲张21例(65.6%)例,此外还发现门静脉海绵状变性2例(5.5%);经SCTA对上述病例分级为一级16例,二级14例,三级6例;肝功能ChildⅠ级14例,ChildⅡ级15例,ChildⅢ级7例,两种分级例数构成无统计学差异(P=0.783)。结论 SCTA技术可较全面地显示门静脉高压时侧支循环开放的情况,且对病变程度的分级与Child分级具有良好的一致性,因此对判断肝硬化程度及预测其并发症具有重要作用。更多还原

【Abstract】 Objective This study is aimed to explore the application of spiral CT angiography (SCTA) for evaluation of the collateral circulation for patients with hepatic cirrhosis complicated with portal hypertension. Methods Thirty-six patients with clinically documented liver cirrhosis were included in this study; they received CT scanning and SCTA. The diameter of portal vein at the level of portal hepatic, the display of portal branches, collateral circulation, together with fistula of hepatic artery, were observed. The correlation between portal venous system changes and the grade of liver cirrohosis and Child grade system were analyzed through Spearman Analysis. Results We classified the patients into 3 grades via SCTA, with 16 of Grade Ⅰ, 14 of grade Ⅱ and 6 of grade Ⅲ, which was highly correlated to Child grading system(P = 0.783). Conclusion Spiral CT angiography (SCTA) is vital for evaluating the severity of hepatic cirrhosis, which is essential for treatment protocol establishment and prognosis.更多还原
