Overview
Pathophysiology
Causes
Classification
Renal artery stenosis may be classified according to whether there is unilateral or bilateral involvement of the renal arteries. Additionally, renal artery stenosis is often classified according to severity of luminal narrowing. The following criteria are used according to most published studies about ARAS.[1][2]
To note, some studies have different classification criteria than those listed below, with mild disease starting after 50% of luminal narrowing. Such classification remains coherent with the definition of ARAS as narrowing > 50%.[3]
| Severity | Luminal Narrowing |
| Normal | 0% |
| Mild | 1-49% |
| Moderate | 50-69% |
| Severe | 70-99% |
| Occluded | 100% |
