Origin
The anterior superior 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 superior segmental artery passes anterior to the renal pelvis, superiorly and laterally towards the superior pole of the kidney. It does not ascend as steeply as the superior segmental artery. It does not extend into the superior pole.
Branches
The anterior superior segmental artery gives rise to interlobar branches, usually one for each renal pyramid within the anterosuperior lobe of the kidney.
Supplied Structures
The anterior superior segmental artery supplies the anterosuperior lobe of the kidney, which includes the central anterosuperior region, extending to the lateral aspect and slightly onto the posterior surface of the kidney. It can be considered to include the inferior-most portion of the superior pole (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.
