Structure/Morphology
The left triangular ligament is a double layer of peritoneum on the superior surface of the liver.
Key Features/Anatomical Relations
The two layers of the left triangular ligament (anterior leaf and posterior leaf) attach to the superior surface of the liver’s left lobe to the diaphragm.
The anterior leaf is continuous with the anterior layer of the coronary ligament, which is continuous with the left layer of the falciform ligament. The posterior leaf is continuous with the lesser omentum.
The left triangular ligament lies anterior to the fundus of the stomach and the distal esophagus (abdominal portion).
Function
The triangular ligaments provide structural support to help hold the liver in place.
