How does liver disease cause hypertension?
A diseased liver can cause portal hypertension, which is high blood pressure in the portal vein. The portal vein supplies the liver with blood. Over time, this pressure causes blood vessels to grow, called collateral blood vessels. These vessels act as channels to divert the blood under high pressure.
Is hypertension related to liver disease?
The most common cause of portal hypertension is cirrhosis, or scarring of the liver. Cirrhosis results from the healing of a liver injury caused by hepatitis, alcohol abuse or other causes of liver damage. In cirrhosis, the scar tissue blocks the flow of blood through the liver and slows its processing functions.
What are the differential diagnosis of portal hypertension?
Cirrhosis of any etiology (viral hepatitis, autoimmune cirrhosis, alcohol-related cirrhosis, primary biliary cirrhosis, etc) Hepatic infiltrative diseases (eg, Wilson disease, hemochromatosis, sarcoidosis) Hepatoportal arteriovenous fistula. Portal vein obstruction.
What is the differential diagnosis for liver cirrhosis?
The most common etiologies of cirrhosis are chronic viral hepatitis B and hepatitis C, nonalcoholic steatohepatitis, and alcoholic liver disease. Some patients with cirrhosis have physical examination findings such as jaundice, spider angiomata, palmar erythema, caput medusa, a firm and enlarged liver, or ascites.
What is chronic liver disease with portal hypertension?
Portal hypertension is a leading side effect of cirrhosis. Your body carries blood to your liver through a large blood vessel called the portal vein. Cirrhosis slows your blood flow and puts stress on the portal vein. This causes high blood pressure known as portal hypertension.
Can liver cirrhosis cause hypertension?
Portal hypertension is elevated pressure in your portal venous system. The portal vein is a major vein that leads to the liver. The most common cause of portal hypertension is cirrhosis (scarring) of the liver.
Does Budd-Chiari cause portal hypertension?
In some cases, if the major hepatic veins are involved, high blood pressure in the veins carrying blood from the gastrointestinal (GI) tract back to the heart through the liver (portal hypertension) may be present. In most cases, the exact cause of Budd-Chiari syndrome is unknown.
What is the differential diagnosis of ascites?
The most common cause of ascites is portal hypertension in 80– 85% of the cases; malignancy, cardiac failure, abdominal tuberculosis and others are less common causes. A diagnostic paracentesis should be performed in the initial evaluation of ascites to determine the cause of ascites and to make the diagnosis of SBP.
