How do you manage renal artery stenosis?

Procedures to treat renal artery stenosis may include:

1. Renal angioplasty and stenting. In this procedure, doctors widen the narrowed renal artery and place a device (stent) inside your blood vessel that holds the walls of the vessel open and allows for better blood flow.
2. Renal artery bypass surgery.

Is renal artery stenosis fatal?

Renal artery stenosis due to fibromuscular dysplasia is a potentially fatal condition, and may result in end-stage renal failure.

When do you stent renal artery stenosis?

Renal artery stenting is a procedure to open the renal arteries – the large blood vessels that carry blood to the kidneys – when they have become blocked due to renal artery stenosis (narrowing of the renal artery). This is most often caused by atherosclerosis or fibrous disease of the arteries.

Is renal artery stenosis reversible?

Angiotensin converting enzyme inhibitors reduce the glomerular filtration rate in about one third of patients with high grade bilateral atheromatous renal artery stenosis. Although this reduction is reversible in most cases, these drugs should be used with utmost caution.

What are the risk factors for renal artery stenosis (RAS)?

The risk factors for any kind of atherosclerosis also apply to RAS, which means anyone with high cholesterol, hypertension, insulin resistance, or a family history of cardiovascular disease may be at higher risk for renal artery stenosis. Other medical conditions, most notably fibromuscular dysplasia (FMD), can also cause renal artery stenosis.

What is the prognosis for renal artery occlusion?

Prognosis The outcome of renal arterial occlusion depends on the speed with which it is treated. Once the blood supply is minimized or cut off to the kidney, tissue death soon results, ultimately leading to chronic kidney failure (end-stage renal disease).

Can renal artery occlusion be cured?

Cure usually suggests that problem has completely resolved. Complete occlusion of renal artery would mean non function of kidney and can not be cured. 25% of people have two renal arteries and second artery can maintain function in part of kidney. Optimal treatment is stent placement by x-ray interventionist. for topic: Renal Artery Occlusion Signs

What is normal renal artery ratio?

Normal mean renal artery RI for an adult is 0.6 with 0.7 the upper limit of normal. In children, RI commonly exceeds 0.7 through 12 months of age and can remain above 0.7 through 4 years of age.
