Von Willibrand Factor Antigen as a Non Invasive Predictor of Portal Hypertension in Patients with Liver Cirrhosis
In cirrhotic livers, increased resistance to portal blood flow is the primary factor in the pathophysiology of portal hypertension (PH) and is caused by structural abnormalities in the hepatic vascular architecture and an increased hepatic vascular tone. Von Willebrand factor antigen (vWF Ag) is released by activated endothelial cells (ECs) and therefore represents an indicator of EC activation and plays ... Read more

Role of portal haemodynamic parameters in prediction of oesophageal varices in cirrhotic patients
BACKGROUND AND STUDY AIMS Screening all cirrhotic patients by endoscopy for detection of varices is not cost-effective as the number of patients increases by time and half of them still would not have developed varices 10 years after being diagnosed with cirrhosis. Therefore, this study aimed to evaluate hepatic haemodynamic Doppler parameters in predicting the presence of oesophageal varices (OVs) ... Read more

Incidence and predictors of rebleeding after band ligation of oesophageal varices
Background and study aims: Variceal bleeding is a severe complication in patients with portal hypertension. Early rebleeding occurs frequently in the first few weeks after band ligation, and the mortality associated with each bleeding episode ranges from 30% to 50%. Our aims were to study the rate of early rebleeding oesophageal varices after band ligation in the Sohag University Hospital, ... Read more

Comparative Study: Valsartan versus Propranolol in Portal Hypertensive Cirrhotic Patients
BACKGROUND: Angiotensin II (A-II) is considered a potential mediator of intrahepatic portal hypertension because its plasma level is elevated in cirrhotic patients. Valsartan-A II blocker- is being tested for use as a portal pressure reducing drug. AIM: To compare haemodynamic changes of 1 week and 1 month treatment with valsartan versus propranolol in cirrhotic portal hypertensive patients. PATIENTS AND METHODS: ... Read more
