Origin

The lateral sacral arteries give rise to spinal branches.

Course

The spinal branches of the lateral sacral arteries enter the first or second anterior sacral foramina and ascend along the cauda equina.

Branches

There are no named branches; however, the spinal branches of the lateral sacral arteries anastomose with those of the lower lumbar and iliolumbar arteries and contribute to the anastomotic ansa around the conus medullaris of the spinal cord (Jones et al., 2013).

Supplied Structures

The spinal branches of the lateral sacral arteries supply the lumbosacral junction, as well as the cauda equina and the conus medullaris of the spinal cord (Standring, 2020).

Artery

ScienceDirect image

When the artery is occluded blood is forced through the collateral vessels, drastically increasing fluid shear stress and triggering an inflammatory response which drives vessel remodeling.
