Gastric varicose vein. Gastroscope (endoscope) view of a bleeding varicose vein in the stomach caused by portal hypertension (high blood pressure in the portal vein). A jet of blood (red) is seen coming from the vein at lower right. Portal hyper- tension occurs when liver damage obstructs the portal vein,which takes blood from the spleen,stomach and intestines to the liver. This causes the veins in the stomach to widen. If a vein ruptures due to the pressure (as seen here),it can cause bouts of vomiting blood and black faeces. Surgery to reduce the pressure in the por- tal vein may effect a cure. Here the bleeding was stopped by applying a tight band around the vein | |
