Origin
The anterior inferior segmental artery is one of four branches of the anterior branch of the renal artery that usually occurs in the hilum of the kidney (renal sinus).
Course
The anterior inferior segmental artery passes anterior to the renal pelvis, laterally and angled slightly inferiorly.
Branches
The anterior inferior segmental artery gives rise to interlobar branches, usually one for each renal pyramid within the anteroinferior lobe of the kidney.
Supplied Structures
The anterior inferior segmental artery supplies the anteroinferior lobe of the kidney, which includes the central anteroinferior region, extending to the lateral aspect and slightly onto the posterior surface of the kidney (Rani et al., 2014).
List of Clinical Correlates
- The segmental arteries of the kidney are virtual end arteries. They supply non-overlapping “segments” of kidney tissue. In other words, the segments are defined by the vascular territories of the segmental arterial branches. This has important implications in kidney segmental resection.

Artery
Arteries are vessels transporting blood between heart, tissues, and other organs in order to supply them with nutrition and oxygen.
