Falciform ligament

The falciform ligament is a broad and thin peritoneal ligament. It is sickle-shaped (Latin: "falciform") and a remnant of the ventral mesentery of the fetus.

It is situated in an anteroposterior plane but lies obliquely so that one surface faces forward and is in contact with the peritoneum behind the right rectus abdominis and the diaphragm, while the other is directed backwards and is in contact with the left lobe of the liver.

Its base or free edge contains between its layers the round ligament, paraumbilical veins and the obliterated umbilical vein. The falciform ligament divides the left and right subphrenic compartments but may still allow passage of fluid from one to the other.

Blood supply 

Blood supply and drainage is very variable, and a separate hepatic falciform artery was only seen in 67% of cadavers in one study 3,4.

  • arterial supply
    • left inferior phrenic artery and middle hepatic artery anastomose to form a single artery that then ramifies as 6-12 branches to supply the falciform ligament
  • venous drainage
    • left inferior phrenic vein drains the falciform ligament
