The vessels draining the plexus into the sinus venosus are termed the venae revehentes, and form the future hepatic veins.
12.
Once the catheter is in the hepatic vein, a wedge pressure is obtained to calculate the pressure gradient in the liver.
13.
In human anatomy, the "'hepatic veins "'are the veins that drain de-oxygenated blood from the liver into the inferior vena cava.
14.
After Kawashima, the only de-oxygenated blood returning to the heart is from the abdominal organs ( via the hepatic veins ) ).
15.
The large hepatic veins arise from smaller veins found within the liver, and ultimately from numerous central veins of the liver lobules.
16.
Ultrasound may show obliteration of hepatic veins, thrombosis or stenosis, spiderweb vessels, large collateral vessels, or a hyperechoic cord replacing a normal vein.
17.
Part of the procedure, a hepatic vein wedge pressure is measured with the assumption of no pressure drop across the liver yielding portal vein pressure.
18.
By creating a shunt from the portal vein to the hepatic vein, this intervention allows portal blood an alternative avenue for draining into systemic circulation.
19.
The tube is placed between the portal and hepatic veins in the liver to relieve high blood pressure that can occur within a diseased organ.
20.
The blood is then drained in the gastrointestinal tract and spleen, where it is taken up by the hepatic veins, and blood is taken back into the heart.
