(26 cards)
What are the lobes of the liver? (4)
- Left lobe
- Right lobe
- Caudate lobe
- Quadrate lobe
- part of the left lobe
What are good landmarks for dividing the liver into left and right (surgically)? (2)
- IVC
2. Gallbladder
What is the hepatic anatomy used for?
A more specific localization
What divides the liver into left and right lobes (anatomically)?
The main lobar fissure
What are 4 landmarks you can see internally in the liver?
- Hepatic veins
- Portal veins
- Ligaments
- Fissures
Why is the right lobe divided into anterior and posterior sections?
The curve of the right lobe is larger than the left, so we need to break it up into smaller segments
What are superior landmarks for the liver?
Hepatic veins
What divides the liver into superior and inferior segments?
Portal vein
What are inferior landmarks for the liver?
Organs
- eg. gallbladder
What are couinauds segments based on?
Portal segments
What does each segment in the liver have? (3)
- Blood supply
- Lymphatics
- Biliary drainage
How many segments are in couinauds segments?

What segment is right anterior superior?
8
What segment is right anterior inferior?
5
What segment is right posterior superior?
7
What segment is right posterior inferior?
6
What segment is the caudate lobe?
1
What does the left hepatic vein separate?
The lateral and medial portion of the left lobe
What does the ascending branch of the left portal vein separate?
The lateral and medial portion of the left lobe
