Vessel
Left suprarenal vein
The principal adrenal tributary of the left renal vein
High-yield
Left adrenal and gonadal drainage usually reach the left renal vein, but inferior phrenic and adrenal tributary patterns have recognized variations.
Overview
The main left adrenal vein usually descends from the gland to the left renal vein. It often joins an inferior phrenic vein before that junction. Its course is generally longer than the direct right adrenal connection to the cava.
Reference facts
- Origin
- Collects central venous drainage at the anterior/inferior aspect of the left adrenal gland.
- Course
- Usually descends toward the superior aspect of the left renal vein, often joining an inferior phrenic tributary.
- Branches
- Commonly receives inferior phrenic drainage; additional collateral channels and variant terminations may occur.
- Supplies
- Returns most left adrenal cortical and medullary blood through a principal central pathway.
- Drains to
- Usually the left renal vein, which subsequently enters the inferior vena cava.
Clinical correlation
The usual left renal-vein route offers a different sampling anatomy from the short right caval route. Variants can alter imaging interpretation and venous access, so a longer vein does not establish procedural safety by itself.
