Stomach, pancreas and gall of the blood, through the large portal, but not directly back to the heart of the capillary into the liver, and then formed into the hepatic veins to the heart; lower esophageal and gastric vein, cardiac blood from the left gastric , Stomach short-portal vein vein, the esophagus and the middle-qi and blood by intravenous injection surprising superior vena cava. When a hardware change or liver portal thrombosis formation, the portal back blocked, the pressure increased, resulting in many of collateral circulation was forced to open to relieve the pressure on the portal, esophageal varices is in this context, from the left gastric, stomach short vein Countercurrent in the (Figure 3). As relatively superficial esophageal veins, varicose veins convex cavity into the esophagus, the result of hard edges and corners of food or damage, acid reflux erosion, severe nausea and vomiting, and other factors, caused the breakdown vein, a large number of bleeding. In China, esophageal varices more than 90 percent from cirrhosis of portal hypertension patients. It can be a barium X-ray or gastroscopy esophagus, esophageal endoscopy confirmed. The main vein for the treatment of esophageal sclerosis vaccination triage treatment or surgery.
