title: Morbidity and mortality of portal hypertension.
abstract: Portal hypertension occurs in several aetiologically distinct disease states associated with either increased flow or increased resistance in the portal venous system. The morbidity and mortality observed are the result of ascites formation, impaired hepatic metabolism, encephalopathy and, most ominously, variceal haemorrhage. Patients with conditions in which there is relatively little hepatic parenchymal damage (non-cirrhotic portal hypertension) tend to have fewer episodes of encephalopathy and are better able to tolerate bleeding episodes than those patients with underlying cirrhosis. Similarly, the development of ascites varies with respect to the aetiology of the portal hypertension. This chapter discusses the natural history of the various disease states that manifest portal hypertension, thus allowing critical evaluation of the various therapeutic modalities used in its treatment.
