Renal artery stenosis

Renal artery stenosis is the narrowing of the renal arteries in the abdomen that provide blood flow to the kindyes. When these arteries become narrowed this can lead to uncontrolled hypertension and kidney dysfunction. At West Michigan Cardiology we offer a variety renal artery stenosis screening and treatment options. Screening for renal artery stenosis starts with a thorough physical exam. If indicated a renal doppler ultrasound can be performed in our office. This is an external ultrasound to assess the blood flow within the renal arteries. If narrowing is suspected the next step is a CT scan of the abdomen or a peripheral angiogram.

A peripheral angiogram is a minimally invasive procedure done in the hospital. During this procedure an small catheter is placed in an artery within the groin. This catheter is advanced up to the renal arteries and contrast dye is injected. This allows the cardiologist to view the renal arteries in real time under fluroscopy. If a severe narrowing is found the doctor will then open the blockage with a specialized balloon. A stent is then placed in the artery to keep it open. Typically patients stay 1 - 2 nights in the hospital after this procedure.
