Liver Flashcards
Who divided liver into functional segment ?
Couinaud
Liver is divided into left and right by which line
Cantlie’s line (it is an imaginary line joining the ICV groove to the medial edge of gall bladder fossa)
Which vein lies beneath the cantlie’s line
Middle hepatic vein
Left side of the liver segment includes
4A , 2 , 3 and 4B segment
Right side of the liver segment includes
5,6,7 and 8 segment
Left hemi liver division based on the left hepatic vein (LHV)
Left medial (4A and 4B) and Left lateral (2 and 3)
LHV lies beneath the
Falciform ligament
Left hemi liver division based on the left portal vein tribuitary is
Left superior (2 and 4A) and Left inferior(3 and 4B)
The right hemi liver division based on right hepatic vein (RHV)
Anterior (5,8) and posterior (6&7)
The right hemi liver is divided into superior and inferior segment based on
Right portal vein tributary.
Which structure divide the liver into various segment
Portal vein ( Single best answer )
Hepatic vein
Which Liver segment forms the gall bladder fossa
4B & 5
Which Liver segment removed during radical cholecystectomy for gall bladder cancer
Segment 4B and 5
Right Posterosuperior segment (segment 7) is known as
Bare area of liver
Right Posterosuperior segment (segment 7 / bare area) is most commonly affected by
Amoebic Liver abscess
Which segment is known as independent segment
Segment - 1 (caudate lobe)
Segment 1 is called as independent segment because
• It receives blood from both sides.
• It drains bile into both sides.
• The venous drainage is directly into the IVC via the short veins.
50% of caudate lobe tissue, encircles the IVC and is called
Caval ligament (it is important while mobilizing the liver during liver resection)
Segment 1 is further subdivided into
Segment 9 and Spigelian lobe
Segment one is involved early in
Colangiocarcinoma
In Budd Chiari syndrome (hepatic, Venus outlaw, obstruction) segment one undergoes hyper trophy because
It has direct drainage into the IVC 
Liver pedicle is present at
Hilum of the liver
Liver pedicle is formed by which three structures
Portal vein (posterior) ;
common bile duct (Dextral, right side )
hepatic artery (left side)
