\u25cf The reason why carotid artery stenosis accounts for 10% of stroke causes<\/em><\/strong><\/p>\n\n\n\n

Carotid artery stenosis is one of the major causes of stroke, and in fact, when stroke patients visit the emergency room and undergo evaluation, about 10% are found to have carotid artery stenosis. Because the carotid arteries are the most important pathways that deliver blood from the heart to the brain, any narrowing or blockage in these vessels can sharply reduce cerebral blood flow. In addition, blood clots that break off from the narrowed area can travel to the brain\u2019s blood vessels and cause a stroke.<\/p>\n\n\n\n

Dr. Minjae Jeong of Seoul Asan Vascular Surgery Clinic stated in an interview that \u201cabout 10% of stroke patients are found to have carotid artery stenosis as the cause,\u201d emphasizing the seriousness of this condition.<\/strong><\/p>\n\n\n\n

Because carotid artery stenosis usually has almost no symptoms, many people do not realize they are in a dangerous condition until they suddenly collapse and are brought to the emergency room.<\/p>\n\n\n\n


\u25cf How carotid artery stenosis develops: Why is the carotid artery particularly vulnerable<\/em><\/strong><\/p>\n\n\n\n

Carotid artery stenosis is mostly caused by atherosclerosis.<\/p>\n\n\n\n

Atherosclerosis is a process in which cholesterol and inflammatory cells accumulate in the vessel wall, causing the artery to gradually thicken and narrow. The carotid artery is particularly vulnerable because its structure includes many sharply bending segments where blood flow turbulence occurs easily.<\/p>\n\n\n\n

This turbulence repeatedly irritates and damages the inner vessel wall, and as fats and inflammatory cells accumulate at the injured site, a plaque forms. As the plaque grows, the artery becomes narrower, and unstable plaque can easily rupture, releasing a clot that travels to the brain and blocks a cerebral artery.<\/p>\n\n\n\n

In other words, carotid artery stenosis is not simply age\u2011related vascular change, but a disease that develops through a complex pathophysiological process: endothelial injury \u2192 inflammation \u2192 plaque formation \u2192 stenosis \u2192 thrombus formation.<\/strong><\/p>\n\n\n\n

Carotid artery stenosis develops through the combined influence of several contributing factors. The major risk factors are as follows.<\/p>\n\n\n\n
