Blockages to the Kidneys
You may be caught by surprise if your doctor says you have blockages in the vessels that supply blood to your kidneys - vessels known as the renal (pronounced REE-nul) arteries. Like most people with this condition, you may not have any symptoms.
About five percent of all patients with high blood pressure have blockages in the kidneys, and 30 percent or more of patients who have blockages in other arteries also have blockages in their kidney arteries.
Blockages to the kidney are an important concern, especially for patients who have high blood pressure, heart failure and other conditions that can put stress on the kidneys.
