07-06 GIT Gx Liver & Hepatobiliary Flashcards
The Cantlie’s line is an oblique plane extending from the ___ to the ___
center of the gallbladder bed to the the inferior vena cava
The right hemiliver comprises segments
5, 6, 7, 8
The left medial section is Couinaud’s segment
4
The superior border of Calot’s triangle is formed by the
inferior surface of the liver
Liver receives 75% of blood flow from the
portal vein
location of the liver
It lies in the RUQ of the abdomen (~7-11th rib)
true or false. Easily palpable at the subcostal margin in normal individuals
false
weight of the liver
around 1200 – 1800gms in a normal individual
Majority of the blood from the small and large intestines is transmitted to the liver thru the
portal vein
it is a potential space above and anterior the diaphragmatic surface of the liver
Sub-phrenic recess of the liver
Sub-phrenic recess of the liver is divided into Left and Right recesses by the
falciform ligament
it is a “dependent area” in the abdomen where one would look for free intraperitoneal fluid
Sub-phrenic recess of the liver
true or false. sub-phrenic recess of the liver is the area where “pneumoperitoneum” in Upright chest x-rays is most evident
false
it is the potential space between the liver and right kidney
Morison pouch
Morison pouch contains the “Bare area” of the liver. true or false
true
Morison pouch. Free blood in the peritoneal cavity is usually evident in this area on ultrasound or CT scan. true or fase
true
Morison pouch is lined/surrounded by peritoneum
false
Boundaries of the “Bare Area” of the liver, EXCEPT: A. Coronary ligaments
B. Left triangular ligament
C. Falciform ligament
D. Right triangular ligament
C. Falciform ligament
Portal Hepatis contains
bile duct,
hepatic artery,
hepatic portal vein
The portal vein is usually formed by the union of:
Superior mesenteric vein & Splenic vein
Which of the following is NOT TRUE about the hepatic veins:
A. Funnels blood from the central veins of the liver into the inferior vena cava B. there are 3x: Right, Middle and Left
C. They are intersegmental, draining the segments adjacent to each
D. Lies in the porta hepatis
all are true
The Right sagittal fissure of the liver is formed by:
Gallbladder & Inferior vena cava
Calot’s Triangle is important because it is the usual location of:
Cystic artery
The valves of Heister are mucosal folds in the
cystic duct
The cystic artery usually arises from the
right hepatic artery
The Ligamentum venosum
is the remnant of the ductus venosus which shunts blood into the inferior vena cava
Which of the following statements is NOT TRUE about the Functional Lobes of the liver?
A. There are 8 functional segments of the liver
B. These segments are not well demarcated from each other
C. Each segment has its own supply from the portal vein and hepatic artery
D. Each segment is drained by individual hepatic ducts and veins
D. Each segment is drained by individual hepatic ducts and veins
A “Left lateral segmentectomy” of the liver entails the removal of which functional lobes:
2 & 3
Which of the following is NOT TRUE about the Caudate lobe:
A. it is also known as the Quadrate lobe
B. it receives its own blood supply from the hepatic artery and portal vein
C. it is often drained by its own hepatic veins which drain directly into the inferior vena cava
D. Corresponds to segment 1 of the functional divisions of the liver
A. it is also known as the Quadrate lobe
the liver is covered by peritoneum EXCEPT in this surface
posterior
the liver is anatomically divided into right and left lobes by the
falciform ligament
the liver is functionally or surgically divided into right and left lobes by the
Cantlie’s line
