Portal hypertension

Portal hypertension is defined as portal venous pressure greater than 12 mmHg.

Causes can be split in their relation to the hepatic sinusoids:

  • dilated portal vein +/- mesenteric veins
  • contrast enhancement of paraumbilical vein: pathognomonic
  • collateral vessels/varices: these are many and can include 4
  • splenomegaly
  • ascites
  • cause of portal hypertension often identified, most commonly liver cirrhosis
  • dietary restriction
  • medication: propranolol, diuretics
  • interventional procedures
    • transjugular intrahepatic portosystemic shunt (TIPSS)
    • surgical portosystemic shunt
    • balloon dilatation of hepatic vein (in case of thrombosis/web in hepatic vein)
    • transhepatic clot thrombolysis (in portal vein thrombosis)
    • splenic artery embolization 3
    • liver transplantation
  • treatment of complications

Dilatation of splenic veins at the splenic hilum without splenomegaly may occur in situations such as state of increased perfusion of splenic tissue associated with an immune response 6.
