Renal artery stenosis

Renal artery stenosis is a medical condition involving the narrowing of one or both of the renal arteries, the blood vessels that carry blood to the kidney from the heart. This condition can lead to hypertension (high blood pressure) and kidney damage.

Causes[edit]

Renal artery stenosis can be caused by atherosclerosis, a condition where plaque builds up in the arteries, or by fibromuscular dysplasia, a condition that causes the walls of the arteries to grow abnormally.

Symptoms[edit]

In many cases, renal artery stenosis does not cause any symptoms. However, in some cases, it can cause high blood pressure that is difficult to control with medication, a decrease in kidney function, or sudden onset of pulmonary edema (fluid in the lungs).

Diagnosis[edit]

Renal artery stenosis can be diagnosed through various tests, including ultrasound, computed tomography (CT) scan, magnetic resonance angiography (MRA), or renal arteriography.

Treatment[edit]

Treatment for renal artery stenosis can include lifestyle changes, medication, or procedures to improve blood flow to the kidneys. These procedures can include angioplasty and stenting, or surgery.
