Question

Answers

1.

A mark was placed in Couinaud segment (CS) 5.

In which Couinaud segment is this mark placed?

One possible answer from CS 1 - 8 (Figure 1)

2.

The software of the TM is able to differentiate between the vessel tree of middle, right, and left hepatic veins.

Please click on any branch of the middle hepatic vein!

3.

A branch of the portal vein is highlighted.

Which vessel is highlighted?

1 = hepatic vein

2 = hepatic artery

3 = portal vein (correct)

4 = bile duct

4.

A branch of the hepatic vein is highlighted.

Which vessel is highlighted?

1 = hepatic vein (correct)

2 = hepatic artery

3 = portal vein

4 = bile duct

5.

The software of the TM is able to differentiate between all 8 CS.

Please click on any vessel branch in CS 7!

The placed dot was automatically recognized by the TM as correct or incorrect.

6.

A mark was placed in the right liver half.

Which liver half is this mark placed in?

1 = left hemi liver (correct)

2 = right hemi liver

7.

Which CS is this tumor located in?

Possible answers from CS 1 to CS 8

8.

An artificial tumor was placed in CS 2 and 3.

Which vessels run through the tumor?

1 = left hepatic vein (correct)

2 = right hepatic vein

3 = left portal vein (correct)

4 = right portal vein

9.

An artificial tumor was placed in CS 2 and 3.

Please describe the shape of the tumor.

1 = rotund

2 = cone-shaped

4 = egg-shaped

10.

An artificial tumor was placed in CS 2 and 3.

How many CS have to be resected in order to remove the tumor completely?

1 = 1 CS

2 = 2 CS (correct)

3 = 3 CS

4 = 4 CS

11.

An artificial tumor was placed in CS 2 and 3.

Please guess which percentage of the liver must be resected to remove the tumor completely!

Students are asked to enter a number ranging from 0% to 100%.
