The document provides an overview of liver anatomy, including its location, surfaces, peritoneal ligaments, subphrenic spaces, blood supply, lymphatic drainage, and the classical versus modern functional anatomy of the liver. It highlights contributions from notable figures like Claude Couinaud and Henri Bismuth in understanding liver segmentation, which allows for targeted surgical resections. Additionally, it discusses the classification and significance of anatomical and functional lobes of the liver.

2. The liver

3. Location …
•Occupies right
hypochondrium +
epigastrium …
•May extends to left
hypochondrium…

4. DEVELOPMENT OF LIVER
• Hepatic Bud –Endoderm
• Pars Hepatica
• Pars cystica
• Septum Transversum-Glissons
capsule,sinusoids of liver

6. Surfaces…
The liver has two surfaces :
1-diaphragmatic surface
2-visceral surface

9. Peritoneal ligaments
• Non Peritoneal Areas;
• Bare area of Liver
• Portahepatis
• Groove for Ivc,fossa for gallbladder.
• Peritoneal ligaments ;
• Coronary ligament,lesser omentum,triangular
ligaments,falciform ligament.

10. SUBPHRENIC SPACES
• Right subphrenic or Rt
anterior intraperitoneal
space -3 surfaces
• Right subhepatic space
or right posterior intra
peritoneal space=right
half of visceral surface
• Right extraperitoneal
space-posterior surface
of right lobe
• Left subphrenic or left
anterior intraperitoneal
space-2 surfaces
• Left subhepatic space or
superior recess-caudate
lobe

11. BLOOD SUPPLY OF LIVER

12. Lymphatic drainage

13. Classical descriptive anatomy of
the liver :

15. Anatomical lobes :
- -Two principal lobes (R & L) separated by
falciform ligament
-Two accessory lobes ( caudate & quadrate lobes
)
- Are not true lobes

16. Right & left lobes :

17. Caudate &quadrate lobes:

18. Comparison between
classical anatomy & modern
functional segmentation of
the liver…

20. Modern functional
anatomy of the liver

21. For knowledge :
Claude Couinaud :
A french surgeon &
anatomist who made
significant contribution in the
field of hepatobiliary surgery
,he was the first to describe
segmental anatomy of the
liver ,,,

23. Because of this division into self-contained units, each segment
can be resected without damaging those remaining. For the
liver to remain viable, resections must proceed along the
vessels that define the peripheries of these segments.
This means, that resection-lines parallel the hepatic veins,
The centrally located portal veins, bile ducts, and hepatic
arteries are preserved.

24. Prof Henri Bismuth :
A french surgeon who
contributes much to the
segmentation of the liver …
His classification is popular in
the USA …while couinauds’
classification is more popular in
Asia & Europe…

25. FUNCTIONAL LOBES
• Cantlie s line
• Middle of gall bladder fossa to the left side of
IVC falls along middle hepatic vein

26. Caudate &quadrate lobes:
