Card 1 of 30Question

What is the anatomical right lobe of the liver?

The large portion of the liver located to the right of the falciform ligament.

In This Section

1. What is the anatomical right lobe of the liver?

The large portion of the liver located to the right of the falciform ligament.

2. Which ligament separates the anatomical right and left hepatic lobes on the diaphragmatic surface?

The falciform ligament.

3. How does the right hepatic lobe compare in size with the left lobe?

The anatomical right lobe is considerably larger than the left lobe.

4. Which Couinaud segments form the functional right liver?

Segments V, VI, VII, and VIII.

5. How does the functional right liver differ from the anatomical right lobe?

The functional right liver excludes segment IV, which lies within the anatomical right lobe.

6. What is Cantlie's line?

An imaginary line from the gallbladder fossa to the inferior vena cava marking the functional division of the liver.

7. Which hepatic vein approximately marks the functional boundary between the right and left liver?

The middle hepatic vein.

8. What are the two functional sections of the right liver?

The right anterior section and right posterior section.

9. Which Couinaud segments form the right anterior section?

Segments V and VIII.

10. Which Couinaud segments form the right posterior section?

Segments VI and VII.

11. Which segment occupies the inferior part of the right anterior section?

Segment V.

12. Which segment occupies the superior part of the right anterior section?

Segment VIII.

13. Which segment occupies the inferior part of the right posterior section?

Segment VI.

14. Which segment occupies the superior part of the right posterior section?

Segment VII.

15. Which hepatic vein approximately separates the right anterior and posterior sections?

The right hepatic vein.

16. Which muscle forms the principal superior relationship of the right hepatic lobe?

The right hemidiaphragm.

17. Which abdominal organ produces the renal impression on the right hepatic lobe?

The right kidney.

18. Which organ produces the suprarenal impression on the right hepatic lobe?

The right suprarenal gland.

19. Which intestinal structure forms the colic impression on the right hepatic lobe?

The right colic flexure.

20. Which part of the duodenum is related to the visceral surface of the right hepatic lobe?

The superior part of the duodenum.

21. What is the bare area of the liver?

A region on the posterior diaphragmatic surface, mainly of the right lobe, that lacks peritoneal covering.

22. Which peritoneal reflections bound the bare area of the liver?

The superior and inferior layers of the coronary ligament.

23. Which ligament is formed where the coronary ligament layers meet laterally?

The right triangular ligament.

24. Which artery usually supplies the functional right liver?

The right hepatic artery, typically arising from the proper hepatic artery.

25. Which portal venous branch primarily supplies the functional right liver?

The right portal vein, usually dividing into anterior and posterior sectoral branches.

26. Which major hepatic vein drains much of the right liver?

The right hepatic vein, which empties into the inferior vena cava.

27. Which duct primarily drains bile from the functional right liver?

The right hepatic duct, usually formed by the right anterior and posterior sectoral ducts.

28. What is a replaced right hepatic artery?

A variant artery, commonly originating from the superior mesenteric artery, that replaces the usual right hepatic arterial supply.

29. Which liver segments are typically removed during a standard right hepatectomy?

Segments V, VI, VII, and VIII.

30. Why is identifying right hepatic vascular and biliary variations important during liver resection?

It helps preserve blood flow and bile drainage to the remaining liver while preventing vascular and ductal injury.
