Does fibromuscular dysplasia cause renal artery stenosis?

Renal artery stenosis (RAS) from fibromuscular dysplasia (FMD) is an uncommon cause of hypertension that affects mostly women. FMD is a noninflammatory vascular disease that predominantly affects mainly the renal arteries, but can also affect arteries in other vascular territories.

What is the most common clinical symptom of renal artery stenosis?

The kidneys play an important role in regulating blood pressure by secreting a hormone called renin. If the renal arteries are narrowed or blocked, the kidneys cannot work effectively to control blood pressure. Persistent or severe high blood pressure is a common symptom of renal artery stenosis.

Is renal artery stenosis common?

How common is renal artery stenosis? Narrowing of the kidney arteries is more common in individuals 50 years of age and older. It is estimated that some degree of narrowing (greater than 50%) is found in about 18% of adults between 65-75 years of age and 42% of those older than 75 years of age.

Who gets renal artery stenosis?

In older individuals, atherosclerosis is by far the most common etiology of renal artery stenosis. Fibromuscular dysplasia may also cause renal artery stenosis, especially in females younger than 50 years. As the renal artery lumen progressively narrows, kidney blood flow decreases.

Can renal artery stenosis cause CKD?

Many but not all patients with atherosclerotic renal artery stenosis have chronic kidney disease (CKD) that is primarily due to a reduction in blood flow induced by the stenosis. In general, clinically progressive CKD as reflected by increased serum creatinine occurs when the stenosis threatens the entire renal mass.

Is fibromuscular dysplasia always fatal?

Fibromuscular Dysplasia is a fatal disease. Although it cannot be cured, proper treatment can allow the patient to deal with the disorder effectively. In many instances, the symptoms of this condition can be kept in control with proper medical attention and patients can enjoy a normal healthy life.

Is fibromuscular dysplasia dangerous?

Fibromuscular dysplasia can weaken the walls of your arteries, creating a bulge called an aneurysm. If an aneurysm ruptures, it can be a life-threatening emergency. An aneurysm can occur in any artery affected by fibromuscular dysplasia.

Is fibromuscular dysplasia hereditary?

Fibromuscular dysplasia causes. The cause of fibromuscular dysplasia is not yet known, but several theories have been suggested. About 7-11% of cases of fibromuscular dysplasia are inherited. In addition about a quarter of patients with fibromuscular dysplasia have had a family member with an aneurysm.

What is treatment for renal stenosis?

Procedures to treat renal artery stenosis may include: Renal angioplasty and stenting. In this procedure, doctors open wider the narrowed renal artery and place a device inside your blood vessel that holds the walls of the vessel open and allows for better blood flow.
