  • Enlarged spleen
  • Varices
  • and others


Most all causes circle around Liver changes (Hepatic).

Posthepatic Causes

  • Inferior Vena Cava Obstruction
  • Right sided Heart failure
  • Hepatic Vein Thrombosis
  • Budd-Chiari Syndrome


  • Testing the via HVPG (Hepatic Venous Pressure Gradient)


***Largely depends on cause


  • Propranolol
  • Nadolol
  • Isosorbide mononitrate
  • Octreotide
  • Terlipressin
