The hepatic round ligament is located above the liver and on the diaphragmatic surface. The liver is divided into two surfaces, the upper and lower, the upper bulge, forward and upward, against the diaphragm, also called the diaphragmatic surface. On its surface it is divided into left and right lobes by the hepatic falciform ligament. Below the liver, also called the dirty surface, there are left and right longitudinal grooves that run anteriorly and posteriorly, and within the anterior part of the left longitudinal groove there is the hepatic round ligament, which is within the free edge of the hepatic falciform ligament and is connected to the umbilicus. During embryonic development, the right umbilical vein atrophies and the left umbilical vein joins the inferior vena cava via a venous conduit. The left umbilical vein gradually closes 1-2 weeks after birth, forming the round hepatic ligament, which is a cord-like structure. The round hepatic ligament has a rich blood supply, which is mainly provided by the right hepatic artery and the abdominal umbilical vein, as well as the peripheral blood vessels in the peritoneal subperitoneal peritoneum.
