Related parts of the anatomy
Origin
The left renal artery originates at the left lateral margin of the aorta, slightly superior to the origin of the right renal artery.
Course
The left renal artery passes anteriorly to the left renal vein, across the left crus of the diaphragm, entering the kidney at the renal hilum.
Branches
The left renal artery branches into the inferior suprarenal and ureteric arteries, and the terminal branches of the anterior and posterior renal branches.
Supplied Structures
The renal artery supplies the perirenal fat, renal capsule, and cortex and medulla of the kidney. The renal artery is one of the three arteries that supply the suprarenal gland, where it supplies the inferior portion of this endocrine gland.
It is one of several sets of segmental arteries that supply the ureter. The renal artery supplies the superior most portion of the ureter.

Renal Artery
Dissection of the renal artery refers to a disruption of the intima that extends into the media (Figs. 1.90 and 1.91), with creation of a false lumen or a double channel, or results in a complete vascular occlusion causing renal infarction.
