About the book
Nowadays, portal hypertension is still potentially lethal. It can cause lots of serious complications, such as gastroesopageal varices and their related gastroinestinal bleeding, ascites, hepatic encephalopathy related to portosystemic shunt, and portopulmonary hypertension syndrome. According to the etiology, it is often classified into pre-hepatic, intra-hepatic, and post-hepatic portal hypertension. Certainly, the main etiology of portal hypertension is liver cirrhosis, followed by extrahepatic portal vein obstruction and hepatic venous outflow obstruction. Hepatic venous pressure gradient (HVPG) is the diagnostic tool for portal hypertension in liver cirrhosis. HVPG >5mmHg refers to the presence of portal hypertension, HVPG >10mmHg indicates the clinically significant portal hypertension, and HVPG >12mmHg suggests a high risk of variceal bleeding. Endoscopy is the golden diagnostic tool for gastroesophageal varices, but is limited by its poor adherence. Besides, diagnostic alternatives for portal hypertension and gastroesophageal varices have been greatly established. There are lots of advances in the management of portal hypertension related complications during recent years. In this book project, we aim to collect a series of manuscripts regarding etiology, epidemiology, diagnosis, and management of portal hypertension. The knowledge is very useful for researchers to explore new issues and for clinicians to treat their patients.
