Portal venous pressure

Portal venous pressure

Portal venous pressure is the blood pressure in the portal vein. It is normally 5-10 mm Hg [ [http://www.emedicine.com/med/byname/esophageal-varices.htm eMedicine - Esophageal Varices : Article Excerpt by: Samy A Azer ...] ] .

An elevated pressure may cause portal hypertension. [ [http://www.springerlink.com/content/l544751202032875/fulltext.pdf Ascites in Cirrhosis Relative Importance of Portal Hypertension and Hypoalbuminemia] DONALI) O. CASTELL, LCDR (MC), USN]

Wedged hepatic venous pressure

Wedged hepatic venous pressure is an estimation of portal venous pressure in alcoholics. In non-alcoholics, however, it underestimates portal venous pressure.
