The stenosis with the highest grade is reported in patients who also have accessory renal artery/arteries in addition to the renal artery on the same side
CT celiac trunk, SMA superior mesenteric artery, RA renal artery, ARA accessory renal artery, IMA inferior mesenteric artery
CT, SMA, RA and ARA: grade 0: no stenosis; grade 1: stenosis < 30%; grade 2: stenosis 30–49%; grade 3: stenosis 50–69%; grade 4: stenosis 70–99%; grade 5: occlusion
IMA: grade 0: no stenosis; grade 1–2: stenosis < 50%; grade 3–4: stenosis 50–99%; grade 5: occlusion
