Approximately one-fourth of all strokes are caused by carotid artery disease, a condition wherein one or both carotid arteries in the neck become blocked by plaque, which can break off and cause stroke. Traditional surgical treatment for carotid artery disease often involves general anesthesia and requires an incision in a patient's neck to remove plaque from inside the artery wall. Carotid artery stenting is a minimally invasive treatment option for patients who require intervention to prevent a stroke and are at high risk for complications from traditional surgery. The procedure is performed by delivering a stent on a catheter through the femoral artery in the groin. The catheter is maneuvered through the patient's vasculature to the carotid artery. The stent, which is designed to prevent arterial plaque and debris from breaking off and blocking blood flow to the brain, is then expanded at the site of the blockage.
The University of Arizona Medical Center for the first time will be part of a national effort to detect life-threatening non-cardiac vascular diseases. UMC is partnering with the American Vascular Association to offer free screenings for people at high risk: 60 years or older with a history of hypertension, diabetes, smoking, high cholesterol, or known cardiovascular disease.
Cordis Endovascular today reported the Circulatory System Devices Panel of the U.S. Food and Drug Administration (FDA) recommended approval of the company's new Cordis Carotid System. Cordis Endovascular is a division of Cordis Corporation, a Johnson & Johnson company.
Research presented in a six-hour symposium on carotid artery disease at the 29th Annual Scientific Meeting of the Society of Interventional Radiology showed carotid artery stenting to be safe and effective for highrisk patients.
Currently, the standard of care for stroke prevention in patients with moderate to severely blocked carotid arteries is carotid endarterectomy surgery. The ARCHeR trials treated patients who were high-risk surgical candidates with carotid artery stenting with and without embolic protection, a device to capture debris that may break off during the procedure.
