ABSTRACT
Portal hypertension is a major cause of morbidity and mortality in liver cirrhosis.
This article provides a background on the most important aspects of the evaluation
of portal hypertension in patients with chronic liver diseases, with special attention
to the measurement of portal pressure by hepatic vein catheterization. The rationale,
technique, applications, costs, and limitations of measurements of the hepatic venous
pressure gradient are thoroughly reviewed. Emerging, noninvasive methodologies for
the evaluation of the patient with portal hypertension are also discussed.
