Thrombosis (blood clot) in the portal vein or the splenic vein, which connects to the portal vein, can cause esophageal varices.actors that increase the risk for bleeding include: 1  High portal blood pressure. 2  The higher the portal pressure, the greater the risk of bleeding. 3  Large varices. 4  Risk of bleeding increases with size of varices. 5  Severe liver disease. 6  Advanced cirrhosis or liver failure increases the risk. 7  Ongoing alcohol consumption.
Increased pressure in the veins that deliver blood to the liver (known as portal hypertension ) leads to the formation of esophageal varices.
