Portal Hypertension: Introduction - Hopkins Medicine

Portal hypertension is a term used to describe elevated pressures in the portal venous system (a major vein that leads to the liver). Portal hypertension may be Portal hypertension may be caused by intrinsic liver disease, obstruction, or structural changes that result in increased portal venous flow or increased hepatic resistance.

Interpretation of peripheral arterial and …

15.07.2020 · Normal venous flow in the larger peripheral and more central veins examined in duplex protocols is spontaneous with low-velocity Doppler waveforms that reflect pressure gradient changes produced by respiratory and cardiac function. Flow velocities are very low in the smaller veins distally in the extremities and may not produce discernable Doppler signals in the resting state. Throughout the ...

increased velocity (compensating for decreased portal vein flow) splenomegaly; ascites; fatty change (variable) Sono elastography may also be useful to assess the amount of liver fibrosis 12. Suggested values for diagnosis 7 kPa: advanced fibrosis; 12.5-15 kPa: cirrhosis; Contrast-enhanced ultrasound may have a role in the diagnosis of cirrhosis: diminished mean hepatic venous transit time is ...
