What defines portal hypertension?

What defines portal hypertension?

• A. Increased pressure in the portal venous system due to liver damage.
• B. Decreased hepatic artery blood flow.
• C. Increased pressure in the systemic venous system.
• D. Blockage of bile flow leading to jaundice.

Answer: (A)

Portal hypertension is defined by increased pressure within the portal venous system, usually due to higher resistance to portal blood flow caused by liver damage such as cirrhosis. When scar tissue distorts the liver's architecture, blood has more trouble passing through the organ, and pressure backs up into the portal system. This elevated pressure can lead to complications like varices, ascites, and splenomegaly, making the concept clinically important. It’s not about the hepatic artery (an arterial supply issue), nor about systemic venous pressure, nor a bile flow obstruction. So the statement describing increased pressure in the portal venous system due to liver damage best defines portal hypertension.
