The hepatic portal vein The portal vein thus drains blood from most of the gastrointestinal tract. Blood then traverses the liver in the hepatic sinusoids and empties into the central veins through which it reaches the inferior vena cava.
Does the hepatic portal vein carry oxygenated blood?
The liver receives a blood supply from two sources. The first is the hepatic artery which delivers oxygenated blood from the general circulation. The second is the hepatic portal vein delivering deoxygenated blood from the small intestine containing nutrients.
What causes a blocked portal vein?
Adults. In adults, cirrhosis is the major etiology, accounting for 24-32% of cases of portal vein thrombosis. Neoplasms are another major cause, accounting for 21-24% of cases of portal vein obstruction, with hepatocellular carcinoma and pancreatic carcinoma causing most of these cases.
How do you clear portal vein?
