HIPERTENSÃO PORTAL (BAVENO) 2005
Portal hypertension is the haemodynamic abnormality associated with the most severe complications of cirrhosis, including ascites, hepatic encephalopathy and bleeding from gastroesophageal varices. Variceal bleeding is a medical emergency associated with a mortality that, in spite of recent progress, is still in the order of 20% at 6 weeks. The evaluation of diagnostic tools and the design and conduct of good clinical trials for the treatment of portal hypertension have always been difficult.
