Аннотация

Portal hypertension (PH) is one of the most common and dangerous factors causing acute bleeding from the upper part of the gastrointestinal tract. Portal hypertension syndrome includes diseases characterized by circulatory disorders in the portal vein and an increase in blood pressure in the portal vein. The main reason for the increase in portal venous pressure in extrahepatic portal hypertension is the presence of obstruction of blood flow in the portal vein. The frequency of occurrence of extrahepatic portal hypertension varies by region. For example, in the United States, it accounts for 65% of total PHs, while in Turkey the figure is 25.8%.
