"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 … " - Normal hepatic venous pressure
