摘要
目的探讨16排螺旋CT血管成像(MSCTA)在显示肝硬化门静脉系统及侧支循环血管方面的应用价值。方法52例肝硬化患者及30例肝脏正常者行腹部增强扫描,然后行门静脉血管成像检查。分别测量门静脉系统短径,并对其进行统计学分析。结果MSCTA显示肝硬化组食管下段静脉曲张21例次,胃底静脉曲张18例次,胃左静脉曲张23例次,胃短、胃后静脉曲张16例次,附脐静脉开放伴腹壁浅静脉曲张7例次,胃-肾/脾-肾分流5例次,奇静脉及半奇静脉扩张7例次,腹膜后静脉曲张4例次。肝脏正常组脾静脉、门静脉、肠系膜上静脉直径均明显小于肝硬化组(P<0.05)。结论16排螺旋CT肝脏血管成像在显示肝硬化门脉系统形态变化及门脉高压侧支循环方面具有重要的临床应用价值。
Objective To study the value of multi-detector row spiral CT angiography（MSCTA） in assessing the portal system and its collateral circulation in patients with liver cirrhosis and portal hypertension. Methods Contrast enhanced abdominal scanning was performed using 16-detector row spiral CT and portal CTA in 30 cases with normal liver,52 cases with liver cirrhosis and 26 cases with portal hypertension. The short diameters of the portal system were measured in both of normal liver and liver cirrhosis patients. Results In the patients with liver cirrhosis and potal hypertension,MSCTA showed esophageal and paraesophageal varices in 21 cases, gastroesphogeal varices in 18 cases, left gastric varices in 23 cases, short gastric or posterior gastric varices in 16 cases, umbilical and abdominal wall varices in 7 cases, splenorenal or gastrorenal shunts in 6 cases, azygos/ hemiazygos varices in 7 cases, and retroperitoneal shunts in 2 cases. In cirrhotic cases, the diameters of portal system were significantly greater than those in normal liver patients （P〈0. 05）. Conclusion MSCTA is a very effective and valuable method for providing important and accurate information of the collateral circulation in cirrhotic patients with portal hypertension.
