Treatment for Renal Artery Stenosis

Advanced Vascular Surgery is southwest Michigan’s leader in treating patients with Renal Artery Stenosis (RAS). This is a serious condition that requires proper treatment to ensure proper blood flow to the kidneys. Without proper treatment could cause serious complications, including kidney failure. Our experienced professionals can properly diagnose this condition then formulate a strategy for addressing and treating the condition to restore the flow of blood to the kidneys, so they can function properly. Read further in today’s post to learn about the causes and symptoms of RAS and how we can treat this condition.

What is RAS and its Symptoms?

Renal Artery Stenosis is a condition in which the renal arteries (which carry blood to your kidneys) become narrowed. The narrowing of these arteries will prevent your kidneys from getting the oxygen-rich blood they need to help filter waste from your system and remove excess fluids. The first sign that you may be suffering from RAS is that your blood pressure will become elevated. If you are already on medication for high blood pressure, you may notice that the medication is no longer working as effectively as it has in the past. If you notice irregularities with your blood pressure, be sure to visit your doctor, or call our office to schedule an appointment for a full evaluation.

How is RAS Diagnosed?

If our specialists believe that you may have RAS, there are things we can do in order to properly diagnose the condition. We can use Ultrasound to identify areas of the arteries that have narrowed while also giving us a clear look at the size of your kidney(s). Using a more invasive Angiography procedure, we can measure the flow of blood in the arteries and identify any blockages or narrow areas. We can also use a CT Scan or a Magnetic Resonance Angiography for more accurate imagery of the arteries to clearly identify RAS.

What are the Treatment Options?

Once RAS has been properly diagnosed, one of the options for treatment is stenting, where the doctor will insert a stent that will hold the artery open and facilitate the blood flow. For more severe cases, the doctor may opt for one of two surgical procedures. The first is a renal endarterectomy that removes the inner arterial lining to leave the artery open for improved blood flow. The other is bypass surgery which is a detour around sections of the artery which have become narrowed or blocked.
