What is the falciform ligament?

A sickle-shaped, double-layered fold of peritoneum connecting the liver to the anterior abdominal wall and diaphragm.

In This Section

1. What is the falciform ligament?

A sickle-shaped, double-layered fold of peritoneum connecting the liver to the anterior abdominal wall and diaphragm.

2. What type of peritoneal structure is the falciform ligament?

A double-layered peritoneal reflection.

3. Which surfaces of the liver are associated with the falciform ligament?

The diaphragmatic surface and the anterior portion of the visceral surface near the inferior border.

4. Which structures receive the anterior and superior attachments of the falciform ligament?

The anterior abdominal wall and the inferior surface of the diaphragm.

5. What is the anatomical significance of the falciform ligament on the diaphragmatic surface of the liver?

It marks the division between the anatomical right and left hepatic lobes.

6. Does the falciform ligament define the functional division between the right and left liver?

No. The functional division follows Cantlie's line, approximately from the gallbladder fossa to the inferior vena cava.

7. Which structure occupies the free inferior border of the falciform ligament?

The ligamentum teres hepatis, also called the round ligament of the liver.

8. What embryological vessel forms the ligamentum teres hepatis?

The left umbilical vein.

9. What was the function of the left umbilical vein during fetal development?

It carried oxygenated blood from the placenta toward the fetal liver.

10. What happens to the left umbilical vein after birth?

It normally closes and becomes the fibrous ligamentum teres hepatis.

11. Through which fissure does the ligamentum teres enter the visceral surface of the liver?

The fissure for the ligamentum teres.

12. Which embryological mesentery gives rise to the falciform ligament?

The ventral mesentery of the foregut.

13. Which other major peritoneal structure develops from the ventral mesentery?

The lesser omentum.

14. How does the falciform ligament relate to the coronary ligament of the liver?

Its peritoneal layers continue superiorly into the anterior layer of the coronary ligament.

15. What tissue is present between the two peritoneal layers of the falciform ligament?

Loose connective tissue containing variable fat, small vessels, and lymphatics.

16. What is the relationship between the falciform ligament and the umbilicus?

Its free inferior border extends toward the umbilicus and contains the round ligament of the liver.

17. Which veins may enlarge within or near the falciform ligament in portal hypertension?

Paraumbilical veins connecting the portal venous system with veins of the anterior abdominal wall.

18. What is recanalization of the paraumbilical veins?

Enlargement of paraumbilical venous channels that can provide collateral drainage in portal hypertension.

19. What clinical sign may result from dilated paraumbilical venous collaterals?

Caput medusae, consisting of dilated superficial veins radiating from the umbilicus.

20. What is the main mechanical role of the falciform ligament?

It provides a peritoneal attachment that helps maintain the liver's position relative to the diaphragm and anterior abdominal wall.

21. Why is the falciform ligament an important landmark during laparoscopic liver surgery?

It helps orient the surgeon to the anatomical division between the right and left hepatic lobes.

22. What is the clinical significance of the falciform ligament during abdominal surgery?

It may be divided for surgical exposure, with care to avoid enlarged paraumbilical vessels.
