Renal Artery Blockages

The physicians of Pennsylvania Vascular Associates are experts in the diagnosis and treatment of renal artery blockages in Philadelphia, PA.

Blocked arteries to your kidneys can cause hypertension or even cause your kidneys to shut down and require dialysis. Specialists at Pennsylvania Vascular Associates can diagnose these blockages with an ultrasound in our non-invasive vascular laboratory, avoiding the use of needles or claustrophobic machines such as an MRI or CT scan, to diagnose the problem.

Risk factors for Renal Artery Blockages

The following risk factors can increase your risk for renal artery blockages:

Diabetes
Smoking
High cholesterol
High blood pressure

Treatment for Renal Artery Blockages

Treatment for renal artery blockages usually involves treating high blood pressure with appropriate medications. If high blood pressure cannot be controlled, the vascular specialists at Pennsylvania Vascular Associates can fix the problem by perfomring balloon angioplasty and stenting to treat narrowed arteries to the kidney. However, we always have a kidney medical specialist (nephrologist) evaluate you before we intervene to be sure they agree nothing else can be done. An appointment with a nephrologist can often be on the same day as the vascular specialist is seen. Very rarely surgery is necessary, which we offer, and which requires an abdominal incision. With successful treatment, renovascular hypertension can be easier to control or even cured. Patients with blocked kidney arteries may be able to be treated in similar ways to prevent them from needing dialysis, if the problem is blocked arteries to the kidneys.

What is Renal Artery Stenosis?

Renal artery stenosis is the blocking of the renal artery, which in turn affects blood flow to the kidneys. When left untreated, renal artery stenosis / blockage can cause kidney failure.

Identifying Issues with a Renal Artery Ultrasound

After hearing of your symptoms, your doctor might refer you to get a renal artery ultrasound which can reveal most major issues with renal artery blockages. The procedure is painless and will allow physicians to accurately treat your renal artery blockage.
