- Primary Outcome Measures
Name Time Method For liver transplant donors and recipients, liver volume increase at 3 months postoperatively (increased portal venous blood flow/wall shear stress postoperatively as an exposure/predictor); for cases of portal vein thrombus (RRT value of the main trunk of the portal vein as an exposure/predictor); and for hepatic encephalopathy, improvement of hepatic encephalopathy after transcatheter portal collateral embolization (increased liver blood flow and changes in blood flow from the superior mesenteric vein into the portal vein due to portosystemic shunt embolization as exposure/predictor) will be evaluated.
