摘　　要：目的 :分析肝硬化门脉高压电子束CT血管造影表现 ,探讨其临床应用价值。方法 :收集 2 4例肝硬化门脉高压患者 ,行 3mm薄层连续容积扫描 ,使用MIP和SSD三维血管重建。结果 :食道下端静脉曲张 9例 ,胃底贲门静脉曲张 13例 ,肝门静脉曲张 6例 ,脾门处脾静脉扭曲扩张 11例 ,2例脾肾静脉自发分流 ,3例附脐静脉开放 ,2例肝硬化合并肝癌。结论 :电子束CT血管造影及血管三维重建在肝硬化门脉高压诊断中具有重要作用 ,对TIPSS手术的术前评估和术后随访有着积极的指导作用。Objective:To analyze electron beam CT angiography characteristics of portal hypertension in liver cirrhosis and to investigate its value of clinical application.Methods:24 patients of portal hypertension were selected in this study by using electron beam CT with MIP (maximum intensity project) and SSD (shade surface display) reconstruction at 3mm thin CVS (continuous volum scan) scanning.Results:Among 24 cases, 9 were lower esophageal vein varices, 13 were fundus-cardia vein varices, 6 were portal hepatis vein varices,11 were splenic vein varices, 2 were shunted splenorenal vein, 3 were recanalized paraumbilical vein, 2 was complicated by hepatocellular carcinoma.Conclusion:Electron beam CT angiography and three-dimensional reconstruction are very important in diagnosing portal hypertension in liver cirrhosis ,and also have positive effects on fore-and-after TIPSS operation evaluation.
