Renal artery stenosis is a narrowing of the arteries that support the kidneys with oxygen-rich blood. As plaque builds up along the walls of these arteries, they gradually stiffen and narrow, reducing blood flow, which in turn damages kidney function and can lead to high blood pressure and eventually, kidney failure.
If you or a loved one has been diagnosed with renal artery stenosis in Northern California, Dignity Health North State can treat your condition and provide personalized care to help you reduce the risk of further complications. To meet with a cardiovascular specialist, Find a Doctor online.
Signs and symptoms of renal artery stenosis are often nonexistent. You can have this condition for years and not even know it. As with many cardiovascular problems, doctors often discover renal artery stenosis during a diagnostic test for another vascular condition or a routine physical examination. Left untreated, renal artery stenosis can lead to kidney problems. These may bring about symptoms of kidney failure, including frequent urination, a decrease in urination, muscle cramps, loss of appetite, and more.
Renal artery stenosis and coronary artery disease are mainly caused by the same thing: a buildup of plaque along the inner walls of the arteries. As this progresses, the tissue of the artery stiffens and becomes narrow, making it difficult for blood to flow through.
In rare cases, renal artery stenosis can be caused by fibromuscular dysplasia, which results in an abnormal growth of the renal artery walls and a narrowing of the opening of the artery.
Our doctors focus on several goals for treatment, including lowering blood pressure, slowing the progression of the disease, and reducing or repairing any blockages in the renal arteries. Depending on how advanced your condition is, your doctor may try a combination of therapies to prevent permanent damage to your kidneys.
