Renal Artery Stenosis: Is It Common & Life Threatening?
Renal Artery Stenosis: Is It Common & Life Threatening? Renal artery stenosis (RAS) occurs when one or more of the arteries that carry blood to your kidneys become narrow. Narrowed arteries make it harder for oxygen-rich blood to travel from your heart to your kidneys. As a result, your kidneys may not be able to properly function, which can lead to other serious health complications. Here is what you should know about RAS before scheduling your next appointment with the trusted team at the Vascular Institute of the Rockies. How Common is RAS? RAS affects over 200,000 people in the United States every year. The majority of individuals who develop RAS also have atherosclerosis, a condition that causes sticky plaque to build up on the inside of your artery walls. Other factors that could make you more likely to be affected by RAS include:
High blood pressure
Men over the age of 45 and women over the age of 55
What Are the Symptoms, Diagnosis, and Complications? In most cases, RAS does not exhibit any noticeable signs or symptoms. Once it has progressed, RAS symptoms may include
High blood pressure that is difficult to manage despite the use of blood pressure medication
Signs of a problem with kidney function such as elevated protein levels in urine
A whooshing sound that your doctor can hear when listening to your kidneys with a stethoscope
Swelling of different body parts, such as your legs
If your healthcare provider suspects that you may have RAS, they will perform a series of tests to confirm the diagnosis. First, they will perform a physical exam, review your health history, and check your kidney function with blood and urine tests. Imaging studies may also be used such as:
Magnetic resonance angiography (MRA)
Possible complications from RAS include:
Chronic kidney disease
Retaining fluid in your legs
Shortness of breath
Renal hypertension (high blood pressure)
Peripheral artery disease
What Happens If It Goes Untreated? If left untreated, RAS can potentially worsen over time. The rate at which the disease can progress, and its prognosis will depend on how severe your condition is. For people whose renal arteries are almost totally blocked (95%), the four-year survival rate is only about 50%. For this reason, it is important to seek treatment as quickly as possible after experiencing symptoms or being diagnosed with RAS. What Are the Treatment Options? Treatment options for RAS will depend on your particular symptoms, lifestyle, and overall health condition. Possible RAS treatment options include:
Making lifestyle changes: eating a balanced diet, limiting salt consumption, drinking more water, and exercising regularly can help keep your blood pressure under control.
Taking medications: Diuretics, angiotensin-converting enzyme (ACE) inhibitors, beta-blockers, and other medications may help manage your blood pressure as well as other conditions contributing to RAS, such as atherosclerosis.
Renal angioplasty and stenting: This procedure is performed to open up narrowed blood vessels and maximize blood flow to the kidney.
Renal artery bypass surgery: This is an open surgical procedure that involves creating a new route for blood to flow from your heart to your kidney via a new conduit such as a bypass graft.
