How can I prevent renal artery stenosis from happening?
Renal artery stenosis is a phenomenon of atherosclerosis and hypertension that is called renovascular hypertension when it affects the blood supply to the kidneys. Renal artery stenosis is in the group of atherosclerotic diseases that can be prevented by mitigating these vascular diseases.
- Smoking cessation.
- Performing physical activity most days most days of the week.
- Lose weight and prevent obesity if overweight.
- Treat dyslipidemia with alterations in diet, exercise, and statins, if necessary. Goals of therapy should be: total cholesterol <200; LDL-C <130; and triglycerides <150.
- Manage hypertensions via diet, weight loss, and antihypertensive medications when necessary.
- Avoid hyperglycemia, especially diabetics.
In patients with significant stenosis, prevention of further damage to the arteries and/or kidney(s) calls for one of three general approaches:
- Medical therapy alone.
- Renal angioplasty percutaneously, usually with stent placement, in addition to medical therapy.
- Surgical revascularization in combination with medical therapy.
