Renal Artery Stenosis

Restore blood flow to kidneys

What is Renal Artery Stenosis?

Renal artery stenosis, also called renal artery disease, is a condition in which the arteries leading to the kidneys become narrowed or blocked with fatty deposits and/or plaque. This buildup happens over time with age, and can cause high-blood pressure. It’s important to diagnose and treat renal artery stenosis quickly because when the kidneys do not have proper blood flow, they’re unable to remove waste and fluids from the body, which can lead to kidney failure.

Symptoms of Renal Artery Stenosis

  • Change in urine output
  • High blood pressure,
    especially at a young age
  • Swelling in face, ankles or feet
  • Darkening skin
  • Muscle cramps
  • Fatigue
  • Sudden weight loss
  • Nausea and vomiting

Advanced Treatment Options

Angioplasty & Stenting: We can use angioplasty to open narrowed renal arteries. Angioplasty is a tiny, deflated balloon we insert with a catheter to the blocked artery, then inflate it to stretch the artery wider to open up blood flow to the kidney. If necessary, to keep it open, we insert a stent, a small mesh tube that stays in place to support the vein walls.

Drug Therapy: We often start with medications, as the first option. We’ll prescribe a medication to dilate or expand the renal arteries to increase blood flow. We may also prescribe a blood thinner.

Surgery: We have two surgical options. One is a renal artery endarterectomy, which is physically removing the plaque. The other is a renal artery bypass, in which we take a healthy segment of vein from another part of your body, and use it to route the blow flow around the blocked area.

Uncontrolled High Blood Pressure May Be From Renal Artery Disease

We’re able to diagnose it in one office visit, and provide treatment that works for your condition and lifestyle.

your condition.

Procedures

Depending upon the severity of your condition, if you have renal artery stenosis, we’ll prescribe medications, or schedule you for angioplasty or surgery.

Recovery

You’ll have 1-2 hours of recovery, and afterward, you may experience mild pain for 2-3 days, which you can treat with over-the-counter pain medication. You’ll be able to resume normal activity in 5-7 days.

After my stress test was normal, Dr. Krikorian explained that the test was around 70% accurate and that I should pay close attention to my body for any warning signs. A few weeks later I was exercising when my energy was zapped in less than 10 minutes and I had a pain under the sternum. I called Dr. Krikorian and he scheduled a cardiac catheterization the next day. He said I showed no sign of a heart attack but he found a 99% blockage in the circumflex artery, which he opened with a stent. I am grateful that he explained possible warning signs and then responded quickly with the catheterization and stent.

Dr. Krikorian performed a laser ablation to treat the vein disease in my right leg. I didn’t even realize how much my left leg hurt from varicose veins until he fixed my right leg! I thought the treatment would be painful, so I was so pleasantly surprised to find that it wasn’t.

My daughter could not believe how good my legs looked! She is going to see Dr. Krikorian too. I was completely satisfied with my treatment and am no longer in pain. The result is fantastic and I highly recommend going to see Dr. Krikorian if you are experiencing any leg pain.

I had suffered with varicose veins for years. I recently went to see Dr. Krikorian at Virtue Vein & Lymphatic Center where he told me everything I needed to know about vein disease and the treatment options. He performed a laser ablation on my diseased vein, and I was able to resume my normal activity the day after my procedure!

Dr. Krikorian is a busy man, but he will take the time necessary to really listen to you and figure out what the problem is. Most doctors these days seem to be talking to the computer, and not the person. Well, here it is the other way around.

Renal Artery Stenosis FAQ

Anyone can develop renal artery disease, but risk factors are:
  • age over 50
  • high cholesterol
  • obesity
  • inactive
  • tobacco use
  • family history of heart disease
  • diabetes

Yes. We will pre-certify any procedure or test prior to your appointment time to ensure it is a covered benefit through your plan.

You can expect mild pain after angioplasty/stenting, or surgery, which can be treated with over-the-counter pain medication.

If we stent the left renal artery the same thing could potentially happen to the right renal artery, so therefore if symptoms return this could be the cause. The artery that previously had a stent placed has a chance to re-narrow despite stent placement, and thus renal artery disease could return.

One of the best ways to prevent renal artery stenosis is to stop smoking. The chemicals in cigarettes damage blood cells and vessels and increase the risk of plaque buildup in the arteries.
