What is the right hepatic duct?

The principal bile duct draining the functional right liver toward the common hepatic duct.

In This Section

1. What is the right hepatic duct?

The principal bile duct draining the functional right liver toward the common hepatic duct.

2. Which Couinaud liver segments normally drain through the right hepatic duct?

Segments V, VI, VII, and VIII.

3. Which two sectoral ducts typically unite to form the right hepatic duct?

The right anterior sectoral duct and right posterior sectoral duct.

4. Which hepatic segments drain into the right anterior sectoral duct?

Segments V and VIII.

5. Which hepatic segments drain into the right posterior sectoral duct?

Segments VI and VII.

6. Where is the right hepatic duct typically formed?

Near the right hepatic hilum, where the anterior and posterior sectoral ducts unite.

7. What is the approximate length of the right hepatic duct?

Usually about 0.5 to 1.5 cm, although its length varies.

8. How does the right hepatic duct usually compare in length with the left hepatic duct?

The right hepatic duct is generally shorter.

9. What is the general course of the right hepatic duct?

It passes medially from the right liver toward the main hepatic duct confluence.

10. Which duct normally joins the right hepatic duct?

The left hepatic duct.

11. What structure is formed by the union of the right and left hepatic ducts?

The common hepatic duct.

12. Where is the right hepatic duct usually positioned relative to the right portal vein?

Generally anterior and superior to the right portal vein near the hepatic hilum.

13. What is the relationship between the right hepatic duct and the hilar plate?

The duct is closely associated with the fibrous hilar plate supporting the hepatic hilar structures.

14. Can the caudate lobe drain bile into the right hepatic duct?

Yes. Segment I may drain into the right hepatic duct, left hepatic duct, or both.

15. What is a common variation involving the right posterior sectoral duct?

It may drain directly into the left hepatic duct instead of joining the right anterior sectoral duct.

16. What is a hepatic duct trifurcation?

A variant in which the right anterior, right posterior, and left hepatic ducts meet at a common confluence.

17. How can an aberrant right posterior sectoral duct relate to the cystic duct?

It may drain directly into the cystic duct, creating a risk of injury during cholecystectomy.

18. What is the effect of a hepatic duct trifurcation on the usual right hepatic duct?

A separate common right hepatic duct is absent.

19. What type of epithelium lines the right hepatic duct?

Predominantly simple columnar epithelium composed of cholangiocytes.

20. What is the primary function of cholangiocytes in the right hepatic duct?

They form a protective epithelial barrier and help modify bile composition.

21. Which arterial system primarily supplies the right hepatic duct?

Branches of the hepatic arterial system, particularly the right hepatic artery.

22. What vascular network supplies the wall of the right hepatic duct?

The peribiliary vascular plexus.

23. Where does venous blood from the right hepatic duct primarily drain?

Into the portal venous system through small peribiliary veins.

24. Which autonomic nerve plexus contributes to the innervation of the right hepatic duct?

The hepatic plexus.

25. Where does lymph from the right hepatic duct primarily drain?

To hepatic hilar lymph nodes, with further drainage toward nodes along the hepatic artery and celiac axis.

26. Why is the right hepatic duct important during right hepatectomy?

Its identification allows division of right-sided biliary drainage while preserving ducts of the remaining liver.

27. Why are right hepatic duct variations important during liver transplantation?

Multiple or aberrant duct openings may require separate biliary anastomoses during graft reconstruction.

28. What can result from obstruction of the right hepatic duct?

Dilation of upstream right intrahepatic bile ducts and impaired drainage of the affected segments.

29. Which malignancy may involve the right hepatic duct near its confluence with the left hepatic duct?

Perihilar cholangiocarcinoma, also called a Klatskin tumor.

30. Which noninvasive imaging technique is commonly used to identify right hepatic duct branching variations?

Magnetic resonance cholangiopancreatography (MRCP).
