Lateral sacral

Lateral sacral artery

The lateral sacral artery is a vital blood vessel that supplies blood to the sacral region of the human body. It is a branch of the internal iliac artery and plays a crucial role in the vascularization of the sacrum and surrounding structures.

Anatomy

The lateral sacral artery typically arises from the posterior division of the internal iliac artery. It is divided into two branches: the superior lateral sacral artery and the inferior lateral sacral artery. These branches descend along the anterior surface of the sacrum, providing blood supply to the sacral vertebrae, the sacral canal, and the overlying muscles and skin.

Superior Lateral Sacral Artery

The superior lateral sacral artery is the upper branch that travels along the upper part of the sacrum. It supplies blood to the upper sacral vertebrae and the surrounding muscles.

Inferior Lateral Sacral Artery

The inferior lateral sacral artery is the lower branch that descends along the lower part of the sacrum. It provides blood to the lower sacral vertebrae, the coccyx, and the adjacent muscles and skin.

Function

The primary function of the lateral sacral artery is to ensure adequate blood flow to the sacral region. This includes the sacral vertebrae, the sacral canal, and the surrounding muscles and skin. Proper blood supply is essential for the health and function of these structures.

Clinical Significance

The lateral sacral artery is of clinical importance in various medical procedures and conditions. It may be involved in surgical interventions related to the sacrum, such as spinal fusion surgeries or the treatment of sacral fractures. Additionally, it can be a site of bleeding in traumatic injuries to the sacral region.
