Middle suprarenal artery
An aortic contribution to the adrenal vascular network
High-yield
A direct aortic origin is the conventional pattern; the three suprarenal groups are named by their usual approach to the gland, not by isolated nonoverlapping territories.
Overview
A middle suprarenal artery commonly leaves the lateral aorta and crosses toward the adrenal gland. It may be small, duplicated, absent or replaced by another origin. Capsular branches blend with the superior and inferior arterial contributions.
Reference facts
- Origin
- Usually from the lateral abdominal aorta around the upper lumbar region, with variable number and alternative origins.
- Course
- Passes laterally across the crural region; the right-sided route commonly lies behind the inferior vena cava.
- Branches
- Forms small capsular branches entering the adrenal vascular network.
- Supplies
- Contributes blood to the gland with overlap through the subcapsular plexus.
- Drains to
- After adrenal capillary passage, blood returns through the suprarenal venous system.
Clinical correlation
The short course near the diaphragmatic crus and, on the right, the cava makes anatomical variation relevant to adrenal imaging and operative vascular planning.
