I70.1: Atherosclerosis of renal artery

Deposits have formed in your renal arteries.

The arteries carry the blood from the heart to the body. In your case, fats and calcium have been deposited in the wall of your renal arteries. This can make the wall of the renal arteries harder and thicker. The deposits can also cause the renal arteries to get narrower. Then, sometimes, not enough blood can get to the renal tissue. Renal tissue may be damaged as a result. If this goes on for a long time, the kidneys may stop working properly.

The kidneys also regulate our blood pressure. When our kidneys receive too little blood, our blood pressure may increase.

Various risk factors can favor deposits in blood vessels. These include, for example, smoking, obesity, and high blood pressure.
