摘要
目的:评价16排螺旋CT门静脉血管成像(MDCTP)技术在显示肝硬化门脉高压侧支循环血管方面的应用价值。方法:对38例临床诊断肝硬化门脉高压的患者行上腹部MDCTP检查。采用MIP、MPR、VR等三维重组技术进行图像后处理,获得门静脉系统及侧支循环血管图像。结果:38例中显示食管胃底粘膜下静脉曲张31例,食管旁静脉曲张10例;胃左静脉曲张29例,胃短静脉曲张26例;脐静脉与腹壁静脉曲张7例;脾-肾或胃-肾分流6例;腹膜后分流2例。结论:MDCTP能显示肝硬化患者门-体侧支循环开放部位、范围及程度,有重要的临床应用价值。
Objective： To study the value of multi-detector row spiral CT portography （MDCTP） in assessing the porto-systemic collateral circulation in patients having liver cirrhosis with portal hypertension. Methods： Contrast enhanced abdominal scanning in 38 patients with documented liver cirrhosis and portal hypertension were performed using 16-detector row spiral CT. Various image post-processing techniques such as MPR ,MIP,VR were applied to depict the porto systemic collateral circulation of portal venous system. Results：Varicosis with engorged and tortuous veins were displayed at various locations in this group of cirrhosis patients with portal hypertension, including gastroesophogeal varices （n= 31 ）, paraesophogeal varices （n=10） .left gastric varices （n=29） , short gastric varices （n=26）, umbilical and abdominal wall varices （n=7）.spleno-renalor gastro-renal shunts （n=6） and the retroperitoneal shunts （n=2） were found. Conclusion：MDCTP technique is a very effective and valuable method for providing important and accurate information of the collateral circulation in cirrhotic patients with portal hypertension.
