Venous Pressure - an overview ScienceDirect Topics

WebWedge hepatic venous pressure is equivalent to portal venous pressure in cirrhosis when the major site of resistance is sinusoidal or presinusoidal (alcoholic and viral hepatitis B and C) or both. A decrease in HVPG of 20% or more from baseline or to 12 mm Hg or less has been shown to correlate with a significant reduction in bleeding. Portal venous pressure is the blood pressure in the hepatic portal vein, and is normally between 5-10 mmHg. Raised portal venous pressure is termed portal hypertension, and has numerous sequelae such as ascites and hepatic encephalopathy. pop up phone case
