Structure

The inferior suprarenal artery usually originates at the trunk of the renal artery. This is usually on its superior surface before its terminal division. It enters the parenchyma of the adrenal gland.

Variations

Variations in the inferior suprarenal artery are common. It usually originates from the renal artery before its final divisions, but may also originate as a final division or after the final divisions. More rarely, it may originate directly from the aorta. It may give off a small branch to the kidney.

There may be two or three inferior suprarenal arteries in some people. Its diameter changes significantly with age.
