Várices esofágicas

World Gastroenterology Organisation Global Guidelines
JANUARY 2014 
"Esophageal varices are Porto-systemic collaterals — i.e., vascular channels that link 
the portal venous and the systemic venous circulation. They form as a consequence of 
portal hypertension (a progressive complication of cirrhosis), preferentially in the sub 
mucosa of the lower esophagus. Rupture and bleeding from esophageal varices are 
major complications of portal hypertension and are associated with a high mortality 
rate. Variceal bleeding accounts for 10–30% of all cases of upper gastrointestinal 
bleeding."
