Elevated Serum Bilirubin
- Unconjugated bilirubin = acute hepatocellular disease
- Conjugated bilirubin = biliary tract obstruction
- Total bilirubin = cirrhosis and chronic liver cell disease
Prolonged PT
Mets
Shorted PT
Extrahepatic duct obstruction
Functions of the liver
- Carbohydrate metabolism
- Lipid metabolism
- aminoacid metabolism
- removal of waste products
- vitamin and mineral storage
- drug inactivation
- synthesis and secretion of bile
non-obstructive jaundice
caused by a cellular defect; unrelated to biliary obstruction
Periportal cuffing
Increase in echogenicity of the walls of the portal triad AKA “Starry-sky” sign
Portal veins
Intersegmental
Hepatic Veins
Intersegmental and interlobar
Main lobar fissure
- separate right and left hepatic lobe
- middle hepatic vein
- GB fossa
Separates anterior right lobe into anterior and posterior
- Rt. Hepatic vein
- Rt. intersegmental fissure
Separates the left lobe into lateral and medial
- Lt. Hepatic vein
- Lt. intersegmental fissure
- Ligament teres
- Falciform ligament
Rt.-sided heart failure often leads to enlargement of the:
