Arteries
A Network of vessels supplying oxygenated blood, nutrients and removing toxins
What is the circulatory system?
This vein runs along the posterior surface of the liver (the bare area)
What is the IVC?
The remnant of ductus venous separates these two lobes of the liver.
What is the Caudate lobe and the left lobe of the liver?
This stimulates the CB to contract
What is CCK?
This bile duct's length is 4cm, diameter is 3mm.
What is Cystic duct?
The primary source of the pressure gradient in the systemic circulation
What is the pumping action of the heart?
This vein's segments are proximal(hepatic) mid portion (suprarenal), distal (infrarenal)
What are the segments of the IVC?
In cirrhosis, this echogenic triangular structure re-opens as an umbilical vein with evidence of venous flow
What is the Ligamentum Teres
This variant can be seen at the neck of the GB
What is Hartman's pouch
This bile duct's length is 8 to 11.5 cm, with a diameter of 1-7mm
What is the CBD?
This is the largest principal artery of the body
What is the Aorta?
This vein runs between the Aorta and SMA
What is the left renal vein?
This structure runs from the GB Fossa, middle hepatic vein, and portion of the caudate lobe to the IVC dividing the Liver into anatomical right and left lobes
What is the main lobar fissure
This Variant is the folding of the fundus
Phrygian cap
These aid in concentrating the bile through water absorption and mucus secretion.
What is inward folds or rugae?
These three vessels branches from the celiac artery
What are the common hepatic, left gastric, and splenic arteries?
This vein drains DIRECTLY into IVC
What is the right gonadel vein
This system divides the liver into eight segments with its own blood supply, lymphatics, biliary drainage, and venous outflow.
What is the Couinaud system?
This bile duct connects the GB and CBD
What is the cystic duct?
This covers the GB
What is the peritoneum?
This major branch of the Common Hepatic Artery runs along the anterolateral aspect of the pancreas and supplies the head of the pancreas, duodenum and stomach. It is an important sonographic landmark for the pancreatic head.
What is the Gastroduodenal Artery?
This vein's sonographic appearance is anechoic tubular in longitudinal plane with thin echogenic walls
What is the IVC?
While one has brighter walls and branches horizontally, the other is thinner and branches vertically
What is the portal and hepatic veins?
The correct way to measure the GB wall thickness:
In transverse, at the anterior aspect of the wall
These 3 structures make up the entrance of the liver
What is the MPV, Hepatic artery, and common bile duct
