Carotid stenting
Carotid Stenting
Carotid stenting (pronunciation: kuh-ROT-id STENT-ing) is a medical procedure used to open narrowed carotid arteries. The term is derived from the Greek words karōtides meaning "sleep-inducing", referring to the carotid arteries' function of supplying blood to the brain, and stenting, named after Charles Thomas Stent, an English dentist who developed the precursor to modern stents.
Procedure
The procedure involves placing a small, expandable tube called a stent into the carotid artery. This is done using a thin tube called a catheter that is guided through the blood vessels from an entry point, usually in the groin. The stent then helps to prop open the artery and decrease the chance of a stroke.
Indications
Carotid stenting is typically recommended for individuals who have a significant arterial stenosis (narrowing of the artery) that is causing symptoms or is likely to cause symptoms in the future. It is also used in patients who are at high risk for carotid endarterectomy, a surgical procedure to remove plaque from the artery.
Risks
Like all medical procedures, carotid stenting carries some risks. These can include stroke, heart attack, and death. However, the risk is generally low and must be weighed against the potential benefits of the procedure.
