Portal Hypertension: Causes, Symptoms, Diagnosis & …
Portal hypertension is an increase in the pressure within the portal vein (the vein that carries blood from the digestive organs to the liver). The increase in pressure is caused by a blockage in the blood flow through the liver. Increased pressure in the portal vein causes large veins ( varices) to develop across the esophagus and stomach to get around the blockage.

Pathophysiology of Portal Hypertension
Portal hypertension is a major complication of liver disease, which results from a variety of pathological conditions that increase the resistance to the portal blood flow into the liver. The primary cause of portal hypertension in cirrhosis is an increase in intrahepatic vascular resistance due to massive structural changes associated with fibrosis and increased vascular tone in the hepatic microcirculation.

Portal hypertension - Wikipedia
Portal hypertension is abnormally increased portal venous pressure – blood pressure in the portal vein and its branches, that drain from most of the intestine to the liver. Portal hypertension is defined as a hepatic venous pressure gradient greater than 5 mmHg. Cirrhosis(a form of chronic liver failure) is the most common cause of portal hypertension; other, less frequent causes are therefore grouped as non-cirrhotic por…

What can portal hypertension lead to?
Portal hypertension may be due to increased blood pressure in the portal blood vessels, or resistance to blood flow through the liver. Portal hypertension can lead to the growth of new blood vessels (called collaterals) that connect blood flow from the intestine to the general circulation, bypassing the liver.
