Non-Invasive versus Invasive Assessment of Portal Hypertension in Chronic Liver Disease

Background: Cirrhosis is one of the major causes of morbidity and mortality worldwide and the second leading cause of digestive disease mortality. Portal hypertension is the main driver of cirrhosis-related complications such as ascites and variceal bleeding. Portal hypertension is defined as a hepatic venous pressure gradient >5 mm Hg, although it is clinically significant and associated with clinical complications when >10 mm Hg. Summary: Therefore, detection of clinically significant portal hypertension (CSPH) in chronic advanced liver disease or compensated cirrhosis is of paramount importance to guide the management of these patients. Key Messages: This study aimed at revising the non-invasive and invasive tools for assessment of portal hypertension and risk stratification for CSPH in patients with chronic liver disease.
