Umbilical vein becomes

Ligamentum teres/ round ligament after birth

Opens back in portal htn. Re canalized umbilical vein.

1

Ductus venosus becomes

Ligamentum venosum

2

Largest organ in the body

Liver

3

Liver is an intraperitoneal organ except the

Bare area. (Area not covered by peritoneum) adj to GB fossa, porta hepatis, and area surrounding IVC.

4

Liver

Weighs 1500grams
Trvs 20-22.5 cm
AP 20-12.5
L 15-20 cm
Convex at diaphragm concave at visceral surface

5

Glisson's capsule aka visceral peritoneum

Fibroelastic connective tissue covering the liver. Has vessels, lymphatics, & nerves.

6

Ligaments

Coronary: where parietal becomes visceral layer. Gives rise to rt & lt triangular ligament

Falciform ligament: divides r & l lobes

Round ligament/Ligamentum Teres

Rt triangular

Lt triangular / lateral ligament

Gastrohepatic

Hepatoduodenal

Ligamentum venosum/hepatogastric lig (post to liver): separates lt lobe & caudate

7

Anatomical division

1.) Right lobe (includes caudate and quadrate)

2.) Left love

Further divided...4 lobes
1.) right
2.) left
3.) caudate
4.) quadrate

8

Segmental division

1.) right lobe
2.) left lobe (including quadrate)
3.) caudate

9

Couinaud Segments

Used for liver resection

1.) caudate lobe
2.) lateral segment lt lobe sup
3.) lateral segment lt lobe inf
4.) quadrate/ medial segment lt lobe sup and inf
5.) ant segment rt lobe inf
6.) posterior segment rt lobe inf
7.) post segment rt lobe sup
8.) ant segment rt lobe sup

10

Liver blood supply and drainage

Hepatic artery: O2 rich
Portal vein: nutrient rich. Most of liver is supplied by PV

Hepatic veins into ivc drains

11

Liver function carried out by

Hepatocytes, biliary epithelial cells, kupffer cells (phagocytes)

12

Liver functions

Digestion, carb metabolism, storage, protein metabolism, detoxification

13

LFT's

Alt, AST, bilirubin, alk phos, LDH, alp, ggtp/ggt inc with alcohol abuse, pt, dec albumin, afp inc cancer.

14

Reidel's lobe

Tongue like projection of rt lobe

15

Transplant Doppler

Normal: RI < 0.8, acceleration time < 0.08, low resistant artery wave.

PRF, 45-60*, depth, sm color box, gain, wall filter, power Doppler on slow flow.

16

Most common liver transplant complication

Ischemic reprofusion injury

Rejection confirmed with biopsy

2nd most common = hepatic artery stenosis

17

Stenosis

Distal tardus parvus wave, vel > 200 cm/s, color aliasing at stenosis

18

Hepatic veins

Right middle left

19

Ligamentum venosum divides

Medial segment Left lobe and caudate lobe.

Remnant of ductus venosus

20

Ligamentum teres divides

Medial and lateral segments of the left lobe.

21

Lab decreases with chronic liver disease

Serum albumin

22

What liver segment is between the left hepatic vein and the middle hepatic vein?

MSLL

23

Reticuloendothelial tissue activity

Digestion of hemoglobin released from ruptured red blood cells.

24

Phagocytic function of the liver is carried out by

Kupffer cells

25

What are the boundaries of the quadrate lobe?

GB fossa, lig teres

26

Milan criteria for patient with HCC

No lesion > 5cm,

27

Reye's syndrome

Associates with pediatric use of aspirin

28

Von Gierkes Type I

MC Glycogen storage disease

29

Wilson's disease

Copper disease. Must avoid organ foods such as liver kidney heart nuts and dried beans.

Brown rings around eyes called Kayser-Fleischer Ring
