Renal Vascular Disease Symptoms

Renal artery stenosis itself doesn't cause symptoms. But if it gets worse, it may cause high blood pressure. Or it may affect how well your kidneys work. Then you may have symptoms of those problems, such as shortness of breath, or fluid buildup that causes swelling in your legs and feet.

Several things may make your doctor think that you have renal artery stenosis. These include blood tests that show that your kidneys don't work as well as they should. Or maybe you were diagnosed with high blood pressure at an early age. Or maybe medicine doesn't lower your blood pressure.
