Oesophageal varices. Endoscopic view of varices (dilated blood vessels) in a patient's oesophagus. Oesophageal varices are extremely dilated sub-mucosal veins (varices) in the lower third of the oesophagus. They are most often a consequence of portal hypertension - high blood pressure in the portal vein and its tributaries. Here,they are a result of primary biliary cirrhosis,an autoimmune disease of the liver,which causes slow progressive destruction of the small bile ducts | |
