Liver Flashcards
The posterior edge of the liver straddles what major vessel?
IVC
What lies posterior to the liver, major vessel?
IVC
The peritoneal duplications of the liver are referred to as ligaments, the diaphragmatic peritoneal duplication are referred to as what?
coronary ligaments (whose lateral margins on right and left side are the triangular ligaments)
This is a thin membrane of anterior liver surface, connecting to the diaphragm, abdominal wall and umbilicus;
falciform ligament
This runs along the inferior edge of the falciform ligament from the umbilicus to the umbilical fissure;
ligamentum teres
What’s the ligamentum teres?
obliterated umbilical vein
What structure used to be the obliterated umbilical vein?
ligamentum teres (runs along the inferior edge of falciform ligament)
On posterior surface of left liver we have the ligamentum venosum, what’s that?
obliterated sinus venosus
How does venous drainage of the liver occur?
thru R, L, and M hepatic veins–> empty into suprahepatic IVC
The liver is covered in peritoneum except in these specific areas:
gallbladder fossa
porta hepatis
on either side of IVC on posterior aspect of liver
What is the area on the posterior liver to the right of IVC called?
bare area of the liver
In the adult liver what does the obliterated umbilical vein and ductus venosus become?
left umbilical vein—> ligamentum teres, runs in the falciform ligament
ductus venosus–> ligmentem venosum
Fetal liver plays an important role in what?
hematopoiesis
What divides the liver into right and left lobes?
Cantlie’s line (portal fissure)
Where does Cantlie’s line run thru which divides the liver into right and left lobes;
runs from the GB to left side of IVC
What segment of liver seen posteriorly embracing IVC?
segment 1 (caudate lobe)
Caudate lobe is also known as which liver segment?
1
What are the segments of the right side of the liver?
5, 6, 7, 8
What are the segments of the left side of the liver?
left medial segments; IV A, IV B
left lateral segments; II, III
What secures the liver to the diaphragm?
right and left triangular ligaments
What ligaments of liver can we dissect in an avascular plane to mobilize it for resection?
falciform, triangular, coronary ligaments, round ligaments
The hapatoduodenal ligament is AKA?
porta hepatis
What does the porta hepatis contain?
portial triad; CBD, hepatic artery, portal vein
What’s the Pringle maneuver?
clamping of the hepatoduodenal ligament which contains the CBD, portal vein and hepatic artery
