Arteriae sacrales laterales

Arteriae Sacrales Laterales

The Arteriae Sacrales Laterales (also known as the lateral sacral arteries) are a pair of blood vessels that supply the sacrum and surrounding structures with oxygenated blood. These arteries are branches of the internal iliac arteries, which are major blood vessels in the pelvic region.

Anatomy

The Arteriae Sacrales Laterales arise from the posterior division of the internal iliac arteries. They typically originate near the level of the sacroiliac joint, which is the joint connecting the sacrum and the ilium bone of the pelvis. Each artery runs laterally along the sacrum, giving off branches to various structures in the area.

Function

The main function of the Arteriae Sacrales Laterales is to provide a blood supply to the sacrum, which is a triangular bone located at the base of the spine. These arteries also supply blood to the surrounding structures, including the sacroiliac joint, the muscles and ligaments of the pelvic region, and the spinal nerves in the sacral region.

Clinical Significance

In certain medical conditions, the Arteriae Sacrales Laterales may become compromised, leading to decreased blood flow to the sacrum and surrounding structures. This can result in pain, dysfunction, and other symptoms. Conditions such as sacroiliitis, sacral fractures, or tumors in the pelvic region can potentially affect the blood supply to the sacrum and may require medical intervention.
