Portal hypertension is a condition in which the blood pressure of the portal venous system is too high. It is often the result of cirrhosis of the liver. Liver cirrhosis can lead to increased intrahepatic vascular resistance and vasodilation of portal system arteries, both of which increase pressure in the portal vein. [4]
Oxygen rich blood is sent to the liver from the heart via the hepatic artery, while the portal vein brings nutrient rich (but depleted in oxygen) blood to the liver from the intestines. This blood passes by the network of capillaries before being evacuated by the hepatic veins into the inferior vena cava and subsequently the heart. The division ...
The human hepatic portal system delivers about three-fourths of the blood going to the liver.The final common pathway for transport of venous blood from spleen, pancreas, gallbladder and the abdominal portion of the gastrointestinal tract [2] (with the exception of the inferior part of the anal canal and sigmoid colon) is through the hepatic portal vein.
