Carotid stenosis refers to the narrowing of the carotid arteries in the neck, which supply oxygenated blood to the brain. This condition is often caused by the buildup of plaque inside the arteries, known as atherosclerosis. Carotid stenosis can lead to decreased blood flow to the brain, increasing the risk of stroke or transient ischemic attacks (TIAs). Research in the area of carotid stenosis focuses on identifying risk factors, developing diagnostic tools, and exploring treatment options to prevent or manage the condition. This includes studying the role of lifestyle factors, genetics, and other health conditions in the development of carotid stenosis, as well as evaluating the effectiveness of medical therapies, surgery, or minimally invasive procedures to reduce the risk of stroke in individuals with this condition. Additionally, researchers are looking into novel approaches such as the use of imaging techniques or biomarkers to improve early detection and monitoring of carotid stenosis.
