Correct Answer » A Explanation |
 |
The cholecystocaval line (Cantlie’s line) is an imaginary line extending from:
- The gallbladder fossa anteriorly
- To the inferior vena cava (IVC) posteriorly
This line represents the functional division of the liver into the right and left hemilivers, based on vascular inflow, biliary drainage, and hepatic venous anatomy.
Unlike the anatomical division by the falciform ligament, the cholecystocaval (Cantlie’s) line is the true functional boundary used in hepatic surgery.
Explanation of the Correct Answer
Option A. Right and left lobes of the liver
- The cholecystocaval (Cantlie’s) line divides the liver into:
- Functional right lobe
- Functional left lobe
- It passes through the middle hepatic vein.
- This is the plane used during hepatic resections and liver transplantation.
Why the Other Options are Incorrect
Option B. Liver from the gallbladder
- The gallbladder lies in the gallbladder fossa on the inferior surface of the liver.
- The cholecystocaval line does not separate the liver from the gallbladder.
Option C. Right lobe of the liver from the gallbladder
- The gallbladder is attached to the inferior surface of the liver and is not separated from the right lobe by the cholecystocaval line.
Option D. Left lobe of the liver from the gallbladder
- The gallbladder is related primarily to the right functional lobe and is not separated from the left lobe by this line.
