Middle adrenal artery
The middle adrenal (suprarenal) artery is one of the three branches that supply the adrenal gland.
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.
Each middle suprarenal artery provides multiple small branches to the gland. In contrast, there is usually only a single vein that drains each gland.
The middle suprarenal artery is the most important artery after the inferior suprarenal artery to supply the gland.
The middle suprarenal artery may occasionally be absent. It has been documented to be present in ~80% of patients 1.
