| Objective: To investigate the value of 16-detector row spiral CT portography in evaluating liver cirrhosis grade and the relationship to episode risks of encephalopathy. Methods: 41 patients with documented liver cirrhosis by clinic, laboratory and various imaging examinations, were included in this study. 19 cases were classified in Child Grade I, 16 in Child Grade II, 6 in Child Grade III. All the patients underwent 16-detector row spiral CT portography. We analysed the diameter of portal vein at the level of porta hepatis, the display of portal branches, collateral circulation, fistula of hepatic artery –portal vein and portal vein embolus. The correlation of portal venous system changes with the grade of liver cirrohosis and Child grade system were studied. The episode risks of encephalopathy were also evaluated by portography. Results: Dialated portal veins were displayed in all 41 cases, with no distinctive correlation to the cirrhosis grade. Portal braches of 4-5 orders were found in all 19 cases of Child Grade I, with esophageal varices and paragastric varices and no fistula of hepatic artety-portal vein or portal vein embolus; Portal braches of 3-4 orders were displayed in all 16 cases of Child Grade II, besides esophageal varices and paragastric varices, cirsomphalos, retroperitoneal varices, paraesophageal varices, dilated azygos vein were also noted, some patients had fistula and portal vein embolus; in... |
