Portal hypertension in cirrhosis is defined as an increase the portal pressure gradient (PPG) between and hepatic veins traditionally estimated by venous (HVPG), which difference free-floating wedged positions of a balloon catheter vein. By convention, HVPG≥10 mmHg indicates clinically significant hypertension, associated with adverse clinical outcomes. Nonalcoholic fatty liver disease (NAFLD) ...

Knowing the normal anatomy, variations, congenital and acquired pathologies of the portal venous system are important, especially when planning liver surgery and percutaneous interventional procedures. The portal venous system pathologies can be congenital such as agenesis of portal vein (PV) or can be involved by other hepatic disorders such as cirrhosis and malignancies. In this article, we p...

Azygos venous blood flow and other haemodynamic parameters were measured in 14 cirrhotic patients to investigate the effects of a non-shunting operation, oesophageal transection with paraoesophagogastric devascularisation. Azygos venous blood flow measured by the local continuous thermal dilution method was significantly reduced by 13.8% after the operation (428 (41) v 369 (33) ml/min). Hepatic...

An endoscopic pressure sensor has been evaluated in the measurement of oesophageal variceal pressure and its response to drug ingestion. The variceal pressure showed a highly significant correlation with the splenic pulp pressure (r = 0.97) in six patients with liver disease of diverse aetiology and with hepatic venous wedge pressure (r = 0.92) in eight alcoholic cirrhotic men. Intraduodenal in...

Hepatic portal venous gas is a rare cause of acute abdomen caused by leakage of air from the gastrointestinal tract to the portal venous system. The mortality is high, particularly when associated with intestinal ischemia or necrosis. We describe a fatal case of hepatic portal venous gas and pneumatosis intestinalis due to hemodialysis-related hypotension and severe atherosclerotic disease.

CONTEXT Hepatitis C is an important cause of chronic liver disease worldwide. The grading of hepatic fibrosis in chronic hepatitis C is important for better clinical management. However, until now, liver biopsy is the only test accepted for this purpose, despite their contraindications and complications. New methods for non-invasive assessment of hepatic fibrosis are under investigation. One pr...
