Liver: Peritoneal Relations, Folds, And Ligaments Flashcards
Liver is completely covered with peritoneum except the following:
- Bare area proper
- IVC groove
- Gall bladder fossa
Bare area proper
On right lobe posterior surface
IVC groove
On right lobe posterior surface
Gall bladder fossa
On right lobe inferior surface
Ligaments
- Lesser omentum (gastrohepatic) ligament
- Falciform ligament
- Coronary ligament
- Right triangular ligament
- Left triangular ligament
Lesser omentum
Peritoneal fold representing ventral mesogastrium posterior part
Lesser omentum ligament extent
Extends between stomach and liver where it is attached to:
1. Porta hepatis margins
2. Margins of Ligamentum venosum fissure
Falciform ligament
Sickle shaped peritoneal fold representing ventral mesogastrium anterior part
Falciform ligament extent
Extends from anterior abdominal wall and diaphragm to liver
Falciform ligament: layers
Formed of 2 layers:
1. Anterior layer: in contact with anterior abdominal wall
2. Posterior layer: in contact with liver
Borders
2 attached and 1 free:
1. Concave border
2. Convex upper border
3. Lower free border
Concave border
Attached to liver anterior and superior surfaces
Convex upper border
Attached to:
1. Diaphragm undersurface
2. Anterior abdominal wall in median plane
Lower free border
- Both layers are continuous
- Enclose Ligamentum teres and paraumbilical veins
- Extends from umbilicus back to Ligamentum teres fissure on liver inferior surface
Contents
- Ligamentum teres and paraumbilical veins: in free border
- Lymph vessels draining umbilicus deep surface: run along Ligamentum teres to drain into porta hepatis nodes
- Extraperitoneal fatty tissue: between both layers
