Recent Approaches in Portal Hypertension Involving Risk Stratification and Medical Management

: Portal hypertension leads to the formation of portosystemic collaterals that divert portal blood to the systemic circulation and bypass the liver, resulting in multiple severe complications. Portal hypertension has classically been diagnosed using invasive methods to calculate the hepatic venous pressure gradient. There has been a recent evolution in portal hypertension pathology emphasizing dynamic changes and integrated pathophysiology, as well as concurrent changes in medical management. There is now a focus on using less-invasive approaches to diagnose portal hypertension and novel treatments that target the various components of evolving portal hypertension pathophysiology. This article details the latest techniques in diagnosing and treating portal hypertension that are becoming cornerstones of portal hypertension management.
