Abstract
Portal hypertension represents a dysfunctional hemodynamic alteration within the portal venous system, usually due to cirrhosis. These altered hemodynamics play a direct role in the development of acute, life-threatening variceal hemorrhage and mark an important pathophysiologic step in the development of other sudden and life-threatening complications such as type 1 hepatorenal syndrome and spontaneous bacterial peritonitis. Many life-saving interventions in these patients are aimed at reducing portal venous pressure. The contribution of portal hypertension to the development of variceal hemorrhage, type 1 hepatorenal syndrome (known also by the name HRS-AKI), and spontaneous bacterial peritonitis in cirrhotic patients is discussed. This article reviews the pathophysiology and incidence of life-threatening complications of cirrhotic portal hypertension, with a discussion of management options and treatment costs.
