Renal Artery Stenosis

Renal artery stenosis is a narrowing of the arteries that supply blood to the kidneys. The condition decreases blood flow and prevents the kidneys, which filter and remove waste from the blood, from functioning properly. As a result, people may develop high blood pressure and, sometimes, damage to kidney tissue. This can result in reduced kidney function or kidney failure.

Renal artery stenosis is most often caused by atherosclerosis, a buildup in the arteries of a hard, waxy substance called plaque. Less commonly, it’s caused by fibromuscular dysplasia, a rare condition that causes growths to appear on the walls of the renal arteries.

Specialists at our NYU Langone heart programs diagnose and manage renal artery stenosis in order to restore kidney function and prevent permanent damage to the kidneys.
