Answer

Portal hypertension is defined as a sustained elevation of portal pressure above normal. An HVPG of 8 mm Hg is believed to be the threshold above which ascites potentially can develop. An HVPG of 12 mm Hg is the threshold for the potential formation of varices. High portal pressures may predispose patients to an increased risk of variceal hemorrhage. [11]
