Localization of liver by functional distribution of portal veins.
Receives branches from both, right and left portal veins and getting drained by emissary veins.
Posteriorly by IVC.
Anterioinferiorly by proximal left portal vein.
Anteriolaterally by ligamentum venosum.
Inferiorly by main portal vein.
Liver is covered by
Glisson’s capsule or Vesceral peritoneum.
Where is liver
Liver invaginates into peritoneum, which covering the liver surface.
Portal v. flow to transducer.
Portal v. flow away from transducer.
3 lobes of liver
Left lobe, Right lobe, caudate lobe.
Left lateral superior
Left lateral inferior
Left medial superior
Left medial inferior
Right anterior superior
Right anterior inferior
Right posterior superior
Right posterior inferior.
Portal vein, hepatic artery, bile duct.
Main lobar fissure
Imaginary line from GB to IVC, middle hepatic vain is landmark for it.
Right and left lobes of the liver.
Right anterior segment from left medial segment.
Right Intersegmental fissure
Coronal division of the right lobe of the liver, dividing right lobe to anterior and posterior, right hepatic vein is landmark for right Intersegmental fissure.
Left Intersegmental fissure
Sagittal division of the left lobe of the liver, divides the left lobe to medial and lateral, the left hepatic vein, ligamentum teres, falciform ligament, assending segment of the left portal vein are landmarks.
Remnant of ductus venosus, conducts blood from the left portal vein to IVC, separates medial segment of left lobe from caudate lobe.
Posterior portion of liver that is not covered by peritoneum.
Reflection of parietal peritoneum onto liver surface, visceral peritoneum.
