Renal Artery Disease

Renal artery disease (RAD), also known as renal artery stenosis, is a condition in which plaque builds up within the arteries that supply blood to the kidneys. The kidneys play an important role in the regulation of normal blood pressure. This plaque can create narrowings or blockages which can interfere with the regulation of blood pressure leading to uncontrolled high blood pressure that remains difficult to treat. Overtime, uncontrolled high blood pressure can lead to kidney compromise, kidney disease, and even kidney failure. Unfortunately, RAD is usually asymptomatic, which means that you will hardly notice anything is wrong. The tell-tale sign of RAD is uncontrollable high blood pressure that cannot be controlled with medication. If you are experiencing high blood pressure, with no relief from a medication regime, feel free to schedule an appointment for consultation or have your primary care provider refer you for an evaluation.
