"WebThe pressure gradient between the portal vein and the IVC (PPG) represents the liver portal perfusion pressure; its normal value is up to 5 mmHg. Direct measurements of portal pressure can be performed through transhepatic or transvenous catheterization of the portal vein. This technique further requires catheterizing the IVC to determine the PPG. " - Normal hepatic venous pressure

Web20 de mai. de 2024 · The normal portal venous waveform is described as “phasic” (Figure 3), with gentle undulation, primarily influenced by atrial contraction. 12 With increases in central venous pressure, RA pressure changes during the cardiac cycle can be transmitted to the portal circulation leading to a “pulsatile” flow pattern as in our case. WebThe hepatic venous pressure gradient (HVPG) is calculated as the difference between the WHVP and FHVP. This gradient is increased with intrahepatic sinusoidal and postsinusoidal PH, but not with prehepatic and presinusoidal intrahepatic PH (where both WHVP and FHVP are usually normal) or with posthepatic PH (where WHVP, FHVP and central venous …
