What Is the Falciform Ligament?
Sickle ligament is a longitudinal fan-shaped ligament of the plantar surface of the liver. Its lower end is connected with the umbilical notch and the hepatic round ligament, and the upper end extends backward and upward and extends left and right into a coronary ligament. The leading edge is connected to the abdominal wall and diaphragm. It has a certain width and is thin. It is often anatomically divided into the left inner and outer liver lobes.

- Sickle ligament is a longitudinal fan-shaped ligament of the plantar surface of the liver. Its lower end is connected with the umbilical notch and the hepatic round ligament, and the upper end extends backward and upward and extends left and right into a coronary ligament. The leading edge is connected to the abdominal wall and diaphragm. It has a certain width and is thin. It is often anatomically divided into the left inner and outer liver lobes.
Sickle ligament anatomy:
- ligament
- The ligament formed by the peritoneum refers to the peritoneal structure that connects the abdomen, the pelvic wall and the organs, or between adjacent organs. Most of them are double-layered, and a few are single-layered peritoneum. Some ligaments contain blood vessels and nerves.
- 1. Liver ligaments The upper part of the liver is sickle ligament, coronary ligament, left and right triangular ligament; the lower part is hepatogastric ligament and hepatoduodenal ligament; the anterior hepatic ligament.
- The sickle ligament is a sagittal double-layer peritoneal structure in the upper part of the anterior abdominal wall and below the sacrum connected to the upper liver. It is located on the right side of the anterior midline and looks like a sickle on the side. The lower edge of the ligament is free and thickened, and contains the hepatic round ligament, which is a remnant formed after the umbilical vein is closed during embryonic time. Because the sickle ligament is on the right side of the midline and the midline incision above the umbilicus needs to be extended downward, it should be turned on the left side of the midline to avoid damage to the hepatic ligament and the accompanying umbilical vein.
- The coronal ligament is a double-layered peritoneum structure formed in the coronal folds from the wall peritoneum below the diaphragm to the liver. The anterior layer extends forward with the sickle ligament, and the liver surface without peritoneal coverage between the anterior and posterior layers is called the bare liver area. The left and right ends of the coronary ligament, the anterior and posterior layers adhere to each other and thicken to form the left and right triangular ligaments.
- 2. Splenic ligaments include gastric spleen ligament, spleen-renal ligament, and spleen-spleen ligament. The gastrosplenic ligament is a double-layered peritoneal structure connected between the base of the stomach and the upper part of the great curvature of the stomach and the spleen hilum, continuing downwards to the left side of the greater omentum. It contains short gastric vessels, left vessels of the gastric omentum, lymphatic vessels, and lymph nodes.
- The splenorenal ligament is a double-layered peritoneal structure from the spleen hilum to the front of the left kidney. It contains pancreatic tail, spleen blood vessels, and lymph and nerves.
- The spleen and spleen ligament is the upper part of the spleen and kidney ligament, which is connected from the upper pole to the lower spleen.
- 3. Stomach ligaments include hepatogastric ligament, gastric spleen ligament, gastrocolonic ligament, and gastric sacral ligament. The first three are as described above. The gastrosacral ligament is a peritoneal structure that connects the left side of the gastric cardia and the esophagus to the lower part of the diaphragm.
