Normal hepatic venous pressure
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. WebNormal portal pressure is 5 to 10 mm Hg (7 to 14 cm H 2 O), which exceeds inferior vena caval pressure by 4 to 5 mm Hg (portal venous gradient). ... прочитати більше ; uncommon causes include blockage of the splenic or portal vein and impaired hepatic venous outflow ...
