Intermediate Right Lobe of the Liver Quiz

Q1. Why does the falciform ligament not define the functional right liver?

• Functional division follows internal vascular and biliary anatomy
• Functional anatomy follows only the inferior border
• The falciform ligament contains the right portal vein
• The right liver lacks segmental anatomy

Q2. Which Couinaud segments form the right anterior sector?

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

Q3. Which Couinaud segments form the right posterior sector?

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

Q4. Which portal branch supplies the right anterior sector?

• Right anterior portal branch
• Left lateral portal branch
• Umbilical vein
• Right posterior portal branch

Q5. Which portal branch supplies the right posterior sector?

• Right posterior portal branch
• Right anterior portal branch
• Left medial portal branch
• Cystic vein

Q6. What is the relationship of the middle hepatic vein to the functional right liver?

• It forms the right hepatic duct
• It lies near the functional right-left hepatic plane
• It lies inside the falciform ligament
• It separates segments VI and VII exclusively

Q7. Which structure bounds much of the bare area of the right lobe?

• Coronary ligament
• Round ligament only
• Greater omentum
• Cystic duct

Q8. Which colonic region commonly contacts the visceral surface of the right lobe?

• Hepatic flexure of the colon
• Sigmoid colon
• Rectum
• Descending colon near the pelvic brim

Q9. How is the right hepatic duct usually formed?

• Union of the cystic and common hepatic ducts
• Union of right anterior and right posterior sectoral ducts
• Union of left medial and left lateral ducts
• Union of hepatic veins

Q10. Why is segmental anatomy important in right liver surgery?

• All right-lobe segments share one indivisible pedicle
• It permits resection along functional vascular and biliary territories
• Only external surface landmarks determine safe resection
• The right lobe has no hepatic venous boundaries
