[Intravascular occlusion in hemorrhages from varicose gastric and esophageal veins].

Endovascular occlusion of the veins which carry the retrograde outflow of blood from the portal system into the system of the superior caval vein through the varicose dilated esophageal veins is known to be one of the most effective methods to stop profuse bleedings due to a disturbed integrity of the varicose dilated veins of the esophagus. It is thought to be expedient to add injections of thrombin to embolization. When performing embolization of the splenic artery it is necessary to exclude possible development of the resulting collateral blood flow via the spleen.
