CAROTID STENOSIS Meaning and
Definition
-
Carotid stenosis refers to the narrowing or constricting of one or both carotid arteries, which are the major blood vessels that supply blood to the brain, head, and neck. The condition typically occurs due to the buildup of plaque, a fatty substance made up of cholesterol, within the inner walls of the arteries.
Carotid stenosis is commonly associated with atherosclerosis, a chronic condition characterized by the deposition of plaque in the arterial walls. This plaque buildup gradually reduces the blood flow through the carotid artery, restricting the supply of oxygen and nutrients to the brain. Carotid stenosis can lead to various complications, including transient ischemic attacks (TIAs) or mini-strokes, as well as an increased risk of a major stroke.
The severity of carotid stenosis is often measured by a grading system ranging from mild to severe based on the degree of artery narrowing. Mild stenosis refers to a narrowing of less than 50%, while severe stenosis indicates an artery narrowing of over 70%. Diagnosis of carotid stenosis usually involves imaging tests such as ultrasounds, CT scans, or MRIs to visualize the arteries and detect any blockages.
Treatment options for carotid stenosis include medication to manage risk factors like high blood pressure and cholesterol levels, as well as surgical interventions such as carotid endarterectomy or carotid angioplasty with stenting. These procedures aim to remove or bypass the plaque buildup, restoring proper blood flow to the brain and reducing the risk of stroke.

Etymology of CAROTID STENOSIS
The word "carotid" originates from the Greek word "karōtis", which means "deep sleep". This term was used by ancient Greeks to describe the carotid artery, as they believed applying pressure on this artery could cause someone to faint or fall into a deep sleep. "Stenosis", on the other hand, is derived from the Greek word "stenōsis", which means "a narrowing or constriction". Thus, "carotid stenosis" refers to the condition characterized by the narrowing or constriction of the carotid artery.
