WebOverview What is portal hypertension? Portal hypertension is elevated blood pressure in your portal vein and the smaller veins that branch off from it — your portal venous system. The portal venous system drains blood from your stomach, intestines, pancreas and spleen into your liver through the portal vein. Your liver filters the blood and then sends it back to … WebPortal hypertension is defined as a hepatic venous pressure gradient (HVPG) (the difference between portal-vein pressure and hepatic-vein pressure) greater than 5 mm Hg, but usually become clinically significant when this gradient reaches 10 mm Hg. Portal venous pressure normally ranges from 7 to 10 mm Hg.
