Renal Artery Disease
Treating Cardiovascular Diseases in Wisconsin and Northern Illinois
Renal artery disease, also known as renal artery stenosis, is a condition that occurs when the arteries that supply blood and oxygen to the kidneys become stiff and narrow. This prevents the kidneys from receiving the blood flow necessary to function properly.
Renal Artery Stenosis Symptoms
Symptoms of renal artery stenosis can include high blood pressure that cannot be controlled by medications and lifestyle changes. Other renal artery disease symptomscan include fluid retention or congestive heart failure. In severe cases, renal artery stenosis can lead to kidney failure, which may include weakness, shortness of breath and fatigue. In some cases, renal artery disease may be asymptomatic, meaning it doesn’t cause symptoms.
Renal Artery Disease Causes and Risks
Renal artery disease is most often caused when plaque builds up in the arteries, a condition known as atherosclerosis. Many of the risks that lead to atherlsclerosis are the same as those for renal artery disease, which include:
- Family history of coronary artery disease, peripheral artery disease or renal artery disease
- High blood pressure
- High cholesterol
- Neurofibromatosis, a genetic disorder that disrupts cell growth in your nervous system
- Over age 50
Diagnosing Renal Artery Disease
Renal artery disease can be diagnosed with non-invasive testing, such as:
- CAT scan (CT or CTA)
- Duplex ultrasound
- Magnetic resonance imaging (MRI or MRA)
- Nuclear medicine testing, such as a captopril renal scan
You may also have an invasive test such as a renal angiogram.
Renal Artery Disease Treatment
It is important for you to have your renal artery disease treated. Without treatment, the disease can progress and lead to kidney failure.
Treatment options include:
- Interventional procedures, such as renal angioplasty or renal stenting
- Lifestyle modifications, such as losing weight, quitting smoking, getting more exercise and eating a low-sodium/low fat-diet
- Medications to control high blood pressure
- Surgery, such renal endarterectomy or renal bypass
