Renal Arteries

Clinical significance. Renal artery stenosis, or narrowing of one or both renal arteries will lead to hypertension as the affected kidneys release renin to increase blood pressure to preserve perfusion to the kidneys. RAS is typically diagnosed with duplex ultrasonography of the renal arteries.

Due to the position of the aorta, the inferior vena cava, and the kidneys in the body, the right renal artery is normally longer than the left renal artery. The right passes behind the inferior vena cava, the right renal vein, the head of the pancreas, and the descending part of the duodenum. The right is somewhat lower than…

aberrant renal arteries: enter via the renal capsule rather than the hilum. early branching (or prehilar branching): occurs in ~10% of the population occurs within 1.5-2.0 cm of origin in the left renal artery or in the retrocaval segment of the right renal artery.
