What causes portal hypertension?

summary

Portal hypertension is a symptom of great harm to the health of patients, now many people do not understand the causes of portal hypertension, ignore the prevention of portal hypertension, leading to their own portal hypertension, then, what is the cause of portal hypertension? People should have an understanding of this problem, so that they can effectively avoid this symptom.

What causes portal hypertension?

1. Cirrhosis is one of the causes of portal hypertension. If patients with cirrhosis are not treated effectively, it will lead to necrotic degeneration of liver cells, failure to form normal hepatic lobules and formation of regenerative nodules. The regenerative nodules compress the peripheral branches of portal vein and vena cava, causing vascular stenosis, interruption or occlusion, When the blood of the portal vein branch flows into the hepatic sinusoid, it will be silted up and the outflow tract of the hepatic vein after the sinusoid is blocked, which will gradually lead to the increase of the portal vein pressure. Therefore, we should take preventive measures in advance after we know what causes the portal hypertension.

2. Liver fibrosis is also a cause of portal hypertension in patients, so it is better to do a good job in prevention. This is due to the central necrosis and fibrosis of the liver lobule, which makes the central venous wall thickening and occlusion, resulting in increased portal pressure.

3. In some patients with liver disease, because they have not received effective treatment, the branches of the hepatic artery of the patients communicate with the branches of the portal vein, forming an arteriovenous short circuit, so that the blood of the hepatic artery flows directly to the branches of the portal vein, which can increase the pressure of the portal vein which has been increased due to obstruction.

matters needing attention

Portal hypertension has a great impact on patients, so we should do the corresponding prevention after understanding the causes of portal hypertension. For patients with portal hypertension, we must treat their own causes, hoping that the disease can be cured as soon as possible.
