Indications and methods for measuring portal hypertension in cirrhosis.

Background and objectives: Over the last decade our understanding of the pathophysiology of portal hypertension has increased. Novel diagnostic technologies have facilitated and improved the diagnosis and treatment of hepatic fibrosis and cirrhosis. With this review we aim to provide an overview of contemporary diagnostic principles of portal hypertension and indications for measuring portal pressure in cirrhosis.

Methods

By review of current literature, we assessed new and old principles of measuring portal hypertension and the diagnostic values of the methods.

Results

Invasive measurement of the portal pressure is still the gold standard to quantitate portal hypertension and to assess response to vasoactive treatment. The size of the portal pressure is important to assess since it contains information on the course of the disease and risk of developing hepatic decompensation, hepatocellular carcinoma, and mortality. Reliable non-invasive Elastography techniques are emerging that adequately assess portal pressure, but the available methods are not yet sufficiently accurate.

Conclusion

Although elastography techniques provide valuable information and are good monitoring tools, liver vein catheterization remains valuable in diagnosing and monitoring portal hypertension, especially in combination with a trans-jugular liver biopsy.
