Renal artery
The renal artery ( Latin ) or renal artery emerges from the main artery ( aorta ) on both sides in the area of the 1st and 2nd lumbar vertebrae . A distinction is made accordingly between an arteria renalis sinistra (left renal artery) and an arteria renalis dextra (right renal artery). The left renal artery runs behind the pancreas (the pancreas ) to the left kidney , the right renal artery runs behind the inferior vena cava ( inferior vena cava ) to the hilum of the right kidney.
The arteria renalis gives off the arteria suprarenalis inferior on both sides , which is involved in the arterial supply of the adrenal gland . Then it divides into the anterior branch and posterior , the front and rear branch on, the anterior branch forms four segmental arteries of Ramus posterior one segment artery.
The corresponding accompanying vein is called the vena renalis (renal vein) and opens into the inferior vena cava .
Variations
There are different standard variants :
- In 10% of cases there is not one renal artery, but two accessory (additional) renal arteries.
- A superior polar artery originates from the renal artery in 13% of cases and supplies the upper part of the kidney.
