The term "ligamentum umbilicale laterale", also known as the lateral umbilical ligament, refers to a structure in the human body that is specifically located in the abdomen. It is an anatomical ligament that runs laterally and is associated with the umbilicus or navel area.
This ligament arises from the deep surface of the lower part of the umbilical artery, which is a blood vessel that connects to the placenta during fetal development. It courses along the lateral edge of the bladder, attaching to the anterior abdominal wall.
The ligamentum umbilicale laterale serves a significant function in adults as a remnant of the fetal circulation system. During embryonic development, it was responsible for carrying blood from the fetus to the placenta. However, after birth, when the baby's lungs take over the oxygenation process, this structure becomes obsolete and gradually transforms into a fibrous ligament.
Clinically, the lateral umbilical ligament is useful for identifying and providing landmarks during certain surgical procedures involving the abdomen, such as hernia repairs or exploratory surgeries. Its presence and location can aid surgeons in locating surrounding structures, including blood vessels or other organs, thereby ensuring precision and reducing the risk of complications during surgical interventions.
In summary, the ligamentum umbilicale laterale is a fibrous remnant of the umbilical artery present in the adult body. Its lateral location and attachment to the abdominal wall make it a useful landmark during certain surgical procedures.
