To review the anatomy of the falciform ligament and its relationship toadjacent structures. To describe and illustrate pathologic conditions which may involve the falciform ligament region,
affecting or not the falciform ligament itself.
The falciform ligament is a sickle-shaped peritoneal double fold that attaches the liver to the anterior abdominal wall and the diaphragm.
It contains the ligamentum teres and the paraumbilical veins,
along with a variable amount of adipose tissue.
It is also the anatomical landmark responsible for the division between left and right subphrenic spaces. The falciform ligament has three edges: The antero-superior or diaphragmatic edge attaches to the inferior surface of the anterior part of the...
Findings and procedure details
Pathologic conditions involving the falciform ligament Related to the ligament content Paraumbilical veins as portosystemic collateral pathway in portal hypertension Paraumbilical veins contained in the falciform ligament establish communication between portal and systemic venous systems,
particularly between left portal vein and epigastric veins ( Fig. 3 ). In portal hypertension,
a variable number of paraumbilical veins,
usually tiny and collapsed,
may enlarge to accomodate an hepatofugal...
Knowledge of the normal anatomy of the falciform ligament region,
together with awareness of the pathologic conditions potentially affecting this area,
may help the radiologist to perform a comprehensive interpretation and achieve an accurate diagnosis.
