The transjugular intrahepatic portosystemic shunt (TIPS) procedure--which involves creation of a shunt through the hepatic parenchyma connecting the hepatic vein
to the portal vein--is one of the most complex procedures performed by the interventional radiologist.
The stenosis is usually at the superior anastomosis and can occur in conjunction with a hepatic vein
This unmatched flexibility is essential in transjugular liver biopsy where the needle must bend to enter the hepatic vein
coming from the liver and collect a specimen via the vessel wall.
Computed tomography (CT) demonstrated a conglomerate of dilated vessels in the region of the porta hepatis with an intrahepatic portosystemic venous shunt, also known as a portal hepatic venous shunt, between the right portal vein and the middle hepatic vein
(Figs 1a and 1b).
12) Occlusion of the hepatic portion of the IVC, major hepatic vein
, or both can lead to BCS, and the prevalence of BCS in BD is 3.
They focus on physiological changes in liver function tests during normal pregnancy; liver disease not specific to pregnancy, such as viral hepatitis, gall stone and biliary disease, hepatic vein
thrombosis, primary biliary cirrhosis, hepatic adenoma, Wilson disease, and portal hypertension; liver disease unique to pregnancy, including hyperemesis gravidarum, intrahepatic cholestasis, preeclampsia-induced liver disease and HELLP (hemolysis, elevated liver enzymes, and low platelets) syndrome, and the acute fatty liver; and transplantation.

At the outflow end of the liver is the hepatic vein
that collects blood from its respective intra-hepatic branches after it passes through the liver.
Pulmonary artery aneurysm accounted for 7%, superior vena cava syndrome 5%, and Budd-Chiari syndrome secondary to hepatic vein
A range of techniques have been developed and used to quantify these gastrointestinal perfusion abnormalities The following techniques have been used to study gastrointestinal perfusion in humans, tonometry, laser Doppler flowmetry, reflectance spectrophotometry, near-infrared spectroscopy, orthogonal polarisation spectral imaging indocyanine green clearance, hepatic vein
catheterisation and measurements of plasma D-lactate.
