Blood Supply of the Adrenal Glands

Introduction
The arterial supply of the adrenal gland consists of three major arteries;
superior adrenal artery
middle adrenal artery
inferior adrenal artery
Blood Supply of the Adrenal Gland |
|
There are three adrenal arteries – the superior adrenal artery arises from the inferior phrenic artery; the middle adrenal artery that arises directly off the aorta; and the inferior adrenal artery that arises from the renal artery usually as a branch of the capsular artery. This schematic only shows 3 branches per vessel, but in reality there is extensive branching before each artery actually enters the gland.

Each vessel enters the gland at various points around their periphery.
The superior adrenal artery arises from the inferior phrenic artery, the middle adrenal artery arises from the abdominal aorta, while the inferior adrenal artery arises from the renal artery.
Superior and Middle Adrenal Arteries |
|
The arteriogram shows the inferior phrenic artery (upper branch) and the middle phrenic artery (lower branch). The inferior phrenic artery gives rise to the superior adrenal artery. The middle adrenal artery is also shown as a red overlay, arises directly off the aorta (not shown) and supplies the mid portion of the the right adrenal gland (yellow overlay).

The Inferior Adrenal Artery |
|
This image reflects the right renal artery with the capsular branch arising from within 2 cm. from the aortic origin. The inferior adrenal artery is overlayed in red and can be seen terminating in a tuft of vessels at the adrenal gland. Copyright 2012 Image courtesy of Ashley Davidoff M.D. 39522 |
The Middle Adrenal Artery Arising from the Inferior Phrenic Artery |
|
The angiogram of the right middle adrenal artery shows a normal arterial phase (a), magnified in b, and a normal capillary phase revealing the triangular shape of the adrenal gland (c yellow overlay). Copyright 2012 Courtesy Ashley Davidoff MD 26566cL01.8 |
The branches of these arteries form a subcapsular plexus from which arise 3 groups vessels;
arteries of the capsule
arteries of the cortex
arteries of the medulla
The arteries of the capsule and the arteries of the cortex, branch repeatedly to form the capillary bed between parenchymal cells and then drain into medullary capillaries;

The arteries of the medulla, pass through the cortex before breaking up to form part of medulla’s extensive capillary network. This dual vascular supply provides the medulla with both arterial and venous blood. The endothelium of these capillaries is extremely attenuated and interrupted by small fenestrae that are closed by thin diaphragms.

Blood Supply of the Adrenal Gland
There are three adrenal arteries – the superior adrenal artery arises from the inferior phrenic artery; the middle adrenal artery that arises directly off the aorta; and the inferior adrenal artery that arises from the renal artery usually as a branch of the capsular artery. This schematic only shows 3 branches per vessel, but in reality there is extensive branching before each artery actually enters the gland.
