Carotid Stent Procedure Live Panel Discussion
Carotid Stents: A New Approach to Treat Carotid Artery Disease
Tampa, Florida – Highlights of a minimally invasive carotid stent procedure to treat carotid artery blockage and prevent strokes shown from Tampa General Hospital. Physicians narrate the procedure and answered your questions as taped highlights were shown. Carotid artery stenting is minimally invasive and replaces open surgery to clean out a blocked artery and has proven to be superior to open surgery in all patients, including high-risk patients. The goal of a carotid stent is to reduce the risk of stroke and improve blood flow to the brain.
Every 45 seconds someone in the United States has a stroke. Stroke or ‘brain attack' occurs when a part of the brain is deprived of blood and oxygen –often as a result of a carotid artery blockage. Lack of oxygenated blood and nutrients causes nerve cell death within minutes. When nerve cell death occurs, the part of the body controlled by the nerve no longer works properly.
Using image-guided techniques, doctors gain access to the carotid artery through a small puncture in the femoral artery located in the groin. A narrow flexible tube is threaded through the artery to the carotid arteries located in the neck. A tiny filter is placed to catch any debris or plaque, which could break off during the stenting procedure. The stent is placed through the narrowed artery and the plaque is "wallpapered" against the blood vessel wall. This procedure takes approximately one hour, has no incisions and patients are usually discharged the following day. For many patients with blocked or narrowed carotid arteries, this procedure is an optimal alternative to open surgery.
The highlights of the procedure are discussed by Dr. Bruce Zwiebel, an interventional radiologist with Radiology Associates of Tampa and Associate Professor of Radiology and Surgery at the University of South Florida College of Medicine, Dr. James Lefler, interventional and therapeutic neuroradiologist with Radiology Associates of Tampa and Associate Professor of Radiology and Neurosurgery at the University of South Florida College of Medicine, and Dr. Brad Johnson, a vascular surgeon at Tampa General Hospital and Associate Professor of Vascular and Endovascular Surgery at the University of South Florida College of Medicine.
