Hepatic transplant

Hepatic Ligaments

The Hepatic ligaments are a group of fibrous bands that connect the liver to the diaphragm and the anterior abdominal wall. They play a crucial role in maintaining the position of the liver within the abdominal cavity.

Anatomy

The hepatic ligaments are composed of five main structures: the falciform ligament, the coronary ligament, the left triangular ligament, the right triangular ligament, and the ligamentum teres hepatis.

Falciform Ligament

The falciform ligament is a thin, crescent-shaped ligament that attaches the liver to the anterior abdominal wall and the diaphragm. It is visible on the anterior surface of the liver and extends from the umbilicus to the diaphragm.

Coronary Ligament

The coronary ligament is a double layer of peritoneum that attaches the liver to the diaphragm. It is divided into the anterior and posterior layers, which enclose a triangular area known as the bare area of the liver.

Left Triangular Ligament

The left triangular ligament is a fold of peritoneum that attaches the left lobe of the liver to the diaphragm. It is smaller than the right triangular ligament.

Right Triangular Ligament

The right triangular ligament is a fold of peritoneum that attaches the right lobe of the liver to the diaphragm. It is larger and longer than the left triangular ligament.

Ligamentum Teres Hepatis

The ligamentum teres hepatis, also known as the round ligament of the liver, is a remnant of the fetal umbilical vein. It runs within the free edge of the falciform ligament and connects the liver to the umbilicus.

Function

The hepatic ligaments help to stabilize the liver within the abdominal cavity and prevent it from moving excessively during bodily movements. They also play a role in the division of the liver into anatomical lobes.

Clinical Significance

Abnormalities or injuries to the hepatic ligaments can lead to liver instability, which can cause discomfort or pain, especially during physical activity. Surgical procedures involving the liver, such as liver transplantation, often require careful manipulation of the hepatic ligaments.
