Portal hypertension is defined as an increase in the pressure gradient between the portal vein and IVC or hepatic veins of 10 to 12 mm Hg or greater. The pathophysiology of IVCS is similar to superior vena cava syndrome (SVCS) because of the presence of an underlying process that inhibits venous return to the right atrium. The IVC collapsibility index has a better predictability value than the diameter of the IVC regarding a patients fluid status. Causes include infection, arteriosclerosis, trauma, and vasculitis. A dilated IVC (>2 cm) has been found to indicate high RA pressure, particularly when there is no collapse during inspiration.
