Falciform ligament

Dr Craig Hacking and Dr Jeremy Jones et al.

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.

It contains between its layers a small but variable amount of fat and its free edge contains the obliterated umbilical vein (ligamentum teres) and if present, the falciform artery and paraumbilical veins. 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.
