The most important portosystem anstomose are gastroesophageal collaterals.Bleeding from esophageal varices makes worse, prevention of bleeding improves a prognosis of patient with liver cirrhosis and portal hypertension.By blood drainage towards vein azigos, those collaterals form the esophageal varices responsible for the most frequent complications of portal hypertension – massive bleeding from the upper parts of digestive tract [1].Bleeding from esophageal varices is an urgent clinical condition followed by high percent of mortality.Summary: Esophageal varices in liver cirrhosis appear due to higher pressure in the system of portal vein and development of portosystem vein collaterals.Besides beta blockers, the long-effect nitrates are used and pro-grammed endoscopic sclerosing and liging of varices.Upon ending of treatment the acute stage of bleeding from esophageal varices, we continue with preventive treatments with an aim to decrease pressure in the flow of portal vein and prevention of repeated bleeding.For this purpose, the non-selective beta blockers were the best because they could be combined with long-effect nitrates as well as programmed endoscopy interventions.The most common reason (in about 90% of all cases) of portal hypertension is liver cirrhosis. The most common causes of liver cirrhosis are alcoholism and virus hepatitis.The obstruction of the flow in this vein of various ethiology results into the increase of vein portal pressure.Portal vein system transfers 1500 ml of blood into the liver from the spleen, stomach, small and large intestines.High portal pressure is the main cause of development of portosystem collaterals, but there are other factors that could also be included, as for example active angiogenesis.Those portosystem collaterals connect the portal vein system with the upper and lower hollow vein.
