Origin

One or two branches arise from the ipsilateral renal artery. Occasionally, the vessels may originate directly from the abdominal aorta or from the gonadal arteries.

Course

The inferior suprarenal artery courses superolaterally and enters the inferior aspect of the adrenal gland.

Branches

Several small branches arise and anastomose with other suprarenal arteries prior to passing through the capsule of the suprarenal gland.

Supplied Structures

The inferior suprarenal artery provides the main vascular supply to the suprarenal gland.

Artery

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.
