Definition
Cardiac liver: consequence of a suprahepatic block
Right heart failure: Constrictive pericarditis, cardiomyopathy... --> causes of right heart failure
Leads to hepatic venous stasis and sinusoidal congestion (slowing of hepatic perfusion and drainage): dilation of centrilobular veins and sinusoidal congestion without inflammation, alteration of centrilobular hepatocytes.
Progression to fibrosis and then to Cirrhosis.
Ultrasound
- hepatomegaly
- dilation of the hepatic veins
- loss of triphasic reflux in the hepatic veins (systolic reflux)
CT
- Reflux into the hepatic veins and the superior vena cava
- Dilation of the hepatic veins
- Congestive liver: hepatomegaly and mosaic perfusion pattern - diffuse periportal edema and periportal edema, sometimes marked gallbladder wall edema
- Chronicity: pseudotumoral hypertrophy of segment I (which receives the first branches of the right and left hepatic arteries: greater regenerative potential)
