New Minimally Invasive Procedure Offers
Relief for Severe Leg Pain by Cleaning Out the Arteries

 

Cardiology Associates of NEA Among the First to Offer Patients the 

SilverHawk™ Plaque Excision System to Open Blocked Leg Arteries

5/25/2004– Cardiology Associates of NEA and St. Bernard’s Hospital now have another alternative to offer the public in the treatment of a painful condition known as peripheral vascular disease (PVD). The SilverHawk™ Plaque Excision System is a new FDA-cleared device for the safe removal of harmful plaque from blocked arteries in the legs.

 

This unique device uses a tiny rotating blade the size of a grain of rice to shave away large quantities of plaque from inside the artery.  As it is excised, the plaque collects in the tip of the device and then is removed from the patient.

 

Before the arrival of plaque excision, treatments for PVD included angioplasty, stenting and open bypass surgery, an invasive procedure, which requires creating a large incision and involves a hospital stay.  Both angioplasty and stenting clear a channel in the artery for blood flow by pushing plaque up against the artery walls.  However, patients often return within six months to have the procedure repeated because plaque has crept back into the artery and blocked it again.

 

The SilverHawk device used by Cardiology Associates physicians; Roger Hill, MD, Fraser Richards, MD, Jack McKee, MD an Tareq Harb, MD cleans out the artery by removing the plaque altogether.  Like angioplasty, plaque excision is a minimally invasive procedure performed through a tiny puncture site.

 

“Some of my patients cannot walk half a block without feeling severe cramping in their legs, commented Dr. McKee “This device provides great relief to those patients and has improved their quality of life immensely.”

 

PVD affects nearly 10 million people in the United States. Similar to cardiovascular disease, PVD is caused by the buildup of fat and cholesterol, known as plaque, which disrupts normal bloodflow to arteries in the vascular system.  Symptoms of the disease often include severe pain, numbness, tingling or weakness in the leg.  Leg pain, known as claudication, can be so extreme that patients may have difficulty in walking short distances.

 

If left untreated, PVD ultimately can lead to amputations.  Last year alone, over 100,000 amputations were performed in the U.S.  In a number of hospitals across the country, plaque excision has been used to save the patient’s leg from amputation after other peripheral interventions have failed.

 

Those at risk of developing PVD include patients with high blood pressure, diabetes and high cholesterol.  Other contributing factors include obesity, smoking and an inactive lifestyle. Screening for peripheral vascular disease is simple and painless so consult with your physician to find out if you are at risk.

 

“Using this procedure, we can remove large quantities of plaque entirely instead of simply compressing it against the vessel wall and hoping it won’t come back,” said Dr. McKee. “Cleaning out the arteries effectively gives a patient’s legs a second chance.”

 

Hill and Richards both have performed the procedure on individuals who had ulcers which would not heal on the lower extremities due to poor circulation to that part of the extremity.  “Once flow was re-established the patients ulcerations began to heal and their symptoms were markedly improved,” remarked Richards.

    Hot post: New Treatment for Leg Pain | St. Bernards Heart & Vascular. My spouse and i ended up being absolutely delighted Ervin managed to complete his preliminary research because of the precious recommendations he obtained out of your weblog. It’s not at all simplistic just to happen to be offering helpful tips which often some other people may have been selling. And we all discover we now have the blog owner to give thanks to for this. All the illustrations you’ve made, the straightforward web site navigation, the friendships you will give support to foster – it’s got mostly spectacular, and it’s really making our son and the family know that this topic is cool, and that is exceedingly pressing. Thanks for everything!
