Ligament
Falciform ligament
Anterior hepatic peritoneal fold with an umbilical remnant
High-yield
The free edge carries the round ligament and paraumbilical veins; the superior fold separates right and left subphrenic recesses.
Overview
The falciform ligament runs between the liver, diaphragm and anterior abdominal wall. Its attachment marks the surface division of the anatomical right and left hepatic lobes, while its free inferior edge encloses the ligamentum teres. This surface line does not define the functional right and left liver.
Reference facts
- Attachments
- Reflects from the anterior abdominal wall and diaphragm onto the anterior/superior liver; its inferior margin extends toward the umbilicus and its upper layers continue into adjacent hepatic reflections.
- Function
- Provides a peritoneal attachment and surface landmark while partly separating the subphrenic peritoneal spaces.
- Clinical point
- Paraumbilical venous channels in this region may enlarge in portal hypertension. They should not all be described as a reopened single fetal umbilical vein, and the fold does not seal the recesses into completely isolated cavities.
Frequently asked questions
Where does the falciform ligament attach?
