Anatomical terminology

The falciform ligament is a ligament that attaches the liver to the anterior (ventral) body wall, and separates the left and right lobe of the liver. The falciform ligament, from Latin, meaning 'sickle-shaped', is a broad and thin fold of peritoneum, its base being directed downward and backward and its apex upward and backward. The falciform ligament droops down from the hilum of the liver.

Structure[edit]

The falciform ligament stretches obliquely from the front to the back of the abdomen, with one surface face in contact with the peritoneum behind the right rectus abdominis muscle and the diaphragm, and the other in contact with the left lobe of the liver.

The ligament stretches from the underside of the diaphragm to the posterior surface of the sheath of the right rectus abdominis muscle, as low down as the umbilicus; by its right margin it extends from the notch on the anterior margin of the liver, as far back as the posterior surface.

It is composed of two layers of peritoneum closely united together.

Its base or free edge contains between its layers the round ligament and the paraumbilical veins.

Development[edit]

It is a remnant of the embryonic ventral mesentery. The umbilical vein of the fetus gives rise to the round ligament of liver of the liver in the adult, which is found in the free border of the falciform ligament.

Clinical significance[edit]

The falciform ligament can become canalised if an individual is suffering from portal hypertension. Due to the increase in venous congestion, blood is pushed down from the liver towards the anterior abdominal wall and if blood pools here, will result in periumbilical bruising.[citation needed]
