Flashcards in Liver Deck (96)
Umbilical vein becomes
Ligamentum teres/ round ligament after birth
Opens back in portal htn. Re canalized umbilical vein.
Ductus venosus becomes
Largest organ in the body
Liver is an intraperitoneal organ except the
Bare area. (Area not covered by peritoneum) adj to GB fossa, porta hepatis, and area surrounding IVC.
Trvs 20-22.5 cm
L 15-20 cm
Convex at diaphragm concave at visceral surface
Glisson's capsule aka visceral peritoneum
Fibroelastic connective tissue covering the liver. Has vessels, lymphatics, & nerves.
Coronary: where parietal becomes visceral layer. Gives rise to rt & lt triangular ligament
Falciform ligament: divides r & l lobes
Round ligament/Ligamentum Teres
Lt triangular / lateral ligament
Ligamentum venosum/hepatogastric lig (post to liver): separates lt lobe & caudate
1.) Right lobe (includes caudate and quadrate)
2.) Left love
Further divided...4 lobes
1.) right lobe
2.) left lobe (including quadrate)
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
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
Liver function carried out by
Hepatocytes, biliary epithelial cells, kupffer cells (phagocytes)
Digestion, carb metabolism, storage, protein metabolism, detoxification
Alt, AST, bilirubin, alk phos, LDH, alp, ggtp/ggt inc with alcohol abuse, pt, dec albumin, afp inc cancer.
Tongue like projection of rt lobe
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.
Most common liver transplant complication
Ischemic reprofusion injury
Rejection confirmed with biopsy
2nd most common = hepatic artery stenosis
Distal tardus parvus wave, vel > 200 cm/s, color aliasing at stenosis
Right middle left
Ligamentum venosum divides
Medial segment Left lobe and caudate lobe.
Remnant of ductus venosus
Ligamentum teres divides
Medial and lateral segments of the left lobe.
Lab decreases with chronic liver disease
What liver segment is between the left hepatic vein and the middle hepatic vein?
Reticuloendothelial tissue activity
Digestion of hemoglobin released from ruptured red blood cells.
Phagocytic function of the liver is carried out by
What are the boundaries of the quadrate lobe?
GB fossa, lig teres
Milan criteria for patient with HCC
No lesion > 5cm,
Associates with pediatric use of aspirin
Von Gierkes Type I
