CT Portography in Grading of Liver Cirrhosis

• Conditions: CT Portography Grading of Liver Cirrhosis

• Registration Number: NCT03453580
• Lead Sponsor: Assiut University

Brief Summary

Esophageal variceal bleeding and hepatic encephalopathy are serious complications of hepatic cirrhosis, and they may lead to high mortality rate and severely threaten life quality of the patients

Detailed Description

The occurrence and development of Esophageal variceal bleeding and hepatic encephalopathy are closely related with portal vein system diseases, such as collateral circulation of portal hypertension and portal vein thrombosis.

The prevention of Esophageal variceal bleeding and hepatic encephalopathy in hepatic cirrhosis has become a hot spot in clinical practice.

Three-dimensional reconstruction of images obtained by multi-slice spiral computed tomography portography (MSCTP) is clear, realistic, and accurate.

It can directly and quickly display all anatomical information of collateral portal vein system, and is recognized as a good method to display blood vessels

Primary Outcome Measures

Name	Time	Method
Grading of liver cirrhosis	15 min	Grade I: i)level 4-5 by portal development will achieved in intrahepatic portal vein imaging; ii) collateral circulation mainly open at esophageal gastric fundus vein, or one branch of para-umbilical vein or esophageal peripheral vein was open; iii) hepatic artery-portal vein fistula or portal vein embolus was not formed.; Grade II: i)level 3-4 by portal development will achieved in intrahepatic portal vein imaging; ii) in addition to opening of collateral circulation at esophageal gastric fundus vein, 2-3 branches of para-umbilical vein or esophageal peripheral vein open; iii) some hepatic artery-portal vein fistula or portal vein embolus not observed.; Grade lll: level 2-3 by portal development are achieved in intrahepatic portal vein imaging; ii) esophageal gastric fundus vein, para-umbilical vein or esophageal peripheral vein all open, iii) hepatic artery-portal vein fistula or portal vein embolus is formed.; Then we will do correlation with child -pugh score

Secondary Outcome Measures

Name	Time	Method
prediction of esophageal varices and hepatic encephalopathy	20 min	measuring diameters of main portal vein,left gastric, splenic, intra hepatic right and left portal vein.
