Web3 de dez. de 2004 · Abstract Portal hypertension, defined as an increase in the hepatic venous pressure gradient above 5 mmhg, can be related to cirrhosis as well as non-cirrhotic disorders. Based on the site of increased resistance, portal hypertension can be classified as presinusoidal, sinusoidal and postsinusoidal.

In half of the patients, the wedged hepatic vein pressure was8 or <8 mmHg. Wedged hepatic venous pressure was significantly (p<0.05) lower than the intrahepatic pressure (15.36±5'57)in non-cirrhoticportal fibrosis patients (Fig. 2). In nearly two-thirds (64'3°/O) of
WebPortal hypertension (PH) is caused by increased resistance, increased blood flow, or both in the portal circulation. The clinical consequences of PH, which include the development of multiple acquired portosystemic shunts (MAPSS), ascites, hepatic encephalopathy (HE), or some combination of these, cause significant morbidity and mortality. 1–3 Reviews of PH … Web31 de out. de 2008 · Hepatic venous pressure gradient (HVPG) is defined as the difference in pressure between the portal vein and the hepatic vein (normally about 1–5 mmHg). When the HVPG increases above 10–12 mmHg, a number of life-threatening complications can occur. These include bleeding from esophageal varices, portal gastropathy, ascites, …

It is determined by wedging a catheter in a hepatic vein, to occlude it, and then measuring the pressure of proximal static blood (which is reflective of pressure in the sinusoids).
