How long do renal artery stents last?
The stent stays in place permanently.
It may be necessary to place more than one stent in the artery.
Once the dent is in place, the inside lining of the artery will grow over the stent in about 8 weeks..
Is renal hypertension curable?
This condition is a treatable form of high blood pressure when properly diagnosed.
How is renal hypertension diagnosed?
Diagnosis is by physical examination and renal imaging with duplex ultrasonography, radionuclide imaging, or magnetic resonance angiography. Angiography is done before definitive treatment with surgery or angioplasty. (See also Overview of Hypertension.)
How do you treat renal artery stenosis?
Procedures to treat renal artery stenosis may include: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.Renal artery bypass surgery.
What are symptoms of renal artery stenosis?
Symptoms of renal artery stenosiscontinued high blood pressure (hypertension) despite taking medications to help lower it.decreased kidney function.fluid retention.edema (swelling), especially in your ankles and feet.decreased or abnormal kidney function.an increase of proteins in your urine.
Can renal stenosis be reversed?
Although these features may be reversed by correcting the stenosis, a classic presentation is uncommon, and hypertension is rarely cured in patients with atheromatous renal artery stenosis.
Can renal stenosis cause fatigue?
In severe cases, renal artery disease can lead to kidney failure, which may cause weakness, shortness of breath and fatigue. In some cases, renal artery disease doesn’t cause any symptoms.
How common is renal artery stenosis?
In younger patients, the narrowing of the renal artery usually is due to the thickening of the artery (fibromuscular dysplasia) and it is more common in women than men. It is estimated that renal artery stenosis accounts for approximately 1% of mild to moderate cases of high blood pressure.
What happens if renal artery is blocked?
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.
How serious is renal stenosis?
Possible complications of renal artery stenosis include: High blood pressure. Kidney failure, requiring treatment with dialysis or a kidney transplant. Fluid retention in your legs, causing swollen ankles or feet.
Is renal stenosis painful?
Renal artery stenosis usually does not cause any specific symptoms. Sometimes, the first sign of renal artery stenosis is high blood pressure that is extremely hard to control, along with worsening of previously well-controlled high blood pressure, or elevated blood pressure that affects other organs in the body.
Who treats renal artery stenosis?
The procedures are performed in a hospital by a vascular surgeon—a doctor who specializes in repairing blood vessels. Anesthesia is needed. Angioplasty and stenting. Angioplasty is a procedure in which a catheter is put into the renal artery, usually through the groin, just as in a catheter angiogram.
