Renal Artery Stenosis (cont.)

What are the signs and symptoms of renal artery stenosis?

High blood pressure is known as the "silent killer." It has no specific symptoms, but over time stresses the major organs in the body and is a risk factor for heart attack and stroke.

Blood pressure elevation with renal artery stenosis is no different; however, the decreased blood flow the kidney(s) over time may cause damage to the kidney(s). Decreased renal function (azotemia), may present with symptoms of fatigue, malaise, and/or slight confusion due to a gradual buildup of waste products in the body.

Your physician may be concerned about renal artery stenosis if high blood pressure has its initial presentation in a person older than age 50 or in a person under the age of 30.

The physical examination may give a clue if a bruit (a rustling sound produced by turbulent blood flow) is heard when your physician listens to the abdomen. If an artery is narrowed, it may cause turbulence as blood flows through the narrowing, causing a noise, like the rapids in a river. This noise is called a bruit.

Renal artery stenosis may also be considered a cause of elevated blood pressure if multiple anti-hypertension medications have failed to control high blood pressure.
