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. WebInstead, measurement of hepatic venous direct and wedge pressure by a transjugular approach has been developed as a safe and reproducible technique to assess portal …
