Renal artery stenosis (RAS) refers to narrowing of the arteries which supply blood to the kidneys. Renal artery stenosis is present in approximately 5% to 10% of people over the age of 65. This risk increases in people with diabetes, obesity, low HDL and in the African American race.
Progression of renal artery disease leads to hypertension, decrease in kidney size and function and ultimately to renal failure and kidney dialysis.
Renal Artery Stenosis is the most common correctable cause of hypertension, or high blood pressure.
The Vascular Specialists of Michigan Vascular Center are experienced in all aspects of this disease. Non-invasive, painless ultrasound testing is usually the first step in making this difficult diagnosis. Although we have a large experience with both the catheter- based and surgical treatment of this disease, most importantly we understand when medical management is the best option.
