Intermediate Right Hepatic Duct Quiz

Q1. Which segments are typically drained by the right anterior sectoral duct?

• Segments V and VIII
• Segments II and III
• Segments I and IV
• Segments VI and VII

Q2. Which segments are typically drained by the right posterior sectoral duct?

• Segments III and IV
• Segments V and VIII
• Segments VI and VII
• Segments II and III

Q3. How is the right hepatic duct commonly formed?

• By union of the right anterior and right posterior sectoral ducts
• By union of the cystic and common hepatic ducts
• By division of the common bile duct
• By fusion of hepatic veins

Q4. Why is the right hepatic duct often more variable than a simple textbook diagram suggests?

• Right sectoral ducts can have variable drainage patterns
• It is replaced by a hepatic vein in most adults
• It normally drains into the renal pelvis
• The duct always follows one invariant pattern

Q5. What is a common clinically important variant involving the right posterior sectoral duct?

• Drainage into the main pancreatic duct
• Drainage into the splenic vein
• Drainage into the ureter
• Drainage into the left hepatic duct

Q6. Why are right hepatic duct variants important before hepatic resection?

• They can change which liver territory depends on a particular duct
• They eliminate portal venous flow
• They make hepatic veins unnecessary
• They determine renal arterial anatomy

Q7. What happens upstream when the right hepatic duct is obstructed proximal to the main hepatic duct confluence?

• The inferior vena cava becomes a bile duct
• The left renal pelvis dilates
• Right-sided intrahepatic ducts may dilate
• The pancreatic tail fills with bile

Q8. Which imaging approach is useful for mapping right hepatic duct branching before complex hepatobiliary surgery?

• Imaging only the femoral artery
• Measuring splenic thickness only
• Imaging only the urinary bladder
• Cholangiographic mapping of the biliary tree

Q9. How does functional hepatic segmentation relate to the right hepatic duct?

• It has no relationship to functional segmentation
• Its branches broadly follow portal-based segmental territories
• It follows hepatic veins exclusively
• It is organized by superficial liver lobes only

Q10. Which statement best describes the right hepatic duct confluence?

• It is always longer than the common bile duct
• It normally enters the duodenum independently
• It usually joins the left hepatic duct, with important sectoral variation
• It always joins the cystic duct first
