Common Causes And Risk Factors For Esophageal Varices

Blood Clots

Blood clots are one of the main causes of esophageal varices. When a blood clot occurs in the splenic vein or portal vein, and the blood goes through other channels to get around the blocked vein, it can lead to esophageal varices. Singular blood clots are referred to as thrombosis. There's also a condition called hepatic vein thrombosis, which occurs when the liver's hepatic veins are obstructed by a blood clot. This condition causes the liver's drainage system to be blocked and impedes the flow of blood back to the heart. When the blood pressure in the portal vein is too high, blood is pushed into the surrounding vessels. In addition to the esophageal varices, varices might develop in the small blood vessels found within the upper portion of a patient's stomach.
