The middle adrenal (suprarenal) artery is one of the three branches that supply the adrenal gland.

Location

The right artery runs between the crus and the inferior vena cava, and behind the bare area of the liver.

The left artery runs behind the posterior wall of the lesser sac, in the stomach bed.
