anterior superior segmental renal artery

A segmental renal artery that 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 and does not extend into the superior pole. It 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.
