Your risks for developing renal artery stenosis (RAS), or a narrowing of the kidney arteries, are similar to that of developing atherosclerosis in any of the body's blood vessels. These include:
Many of these risk factors are "modifiable," which means you can take steps to reduce your risk. Being aware of your risk factors and trying hard to reverse them can make a big difference.
Fibromuscular dysplasia (FMD) can cause RAS and has a tendency to run in certain families. Family history of FMD can be considered as a risk factor for RAS as well.
Patients may develop RAS after a kidney transplant. Factors contributing to RAS within this population may result from the surgery itself, accelerated buildup of plaque in the blood vessels, and specific viral infections that transplant patients are more likely to get. Typically, this occurs between three months and two years post-transplant.
