Some dizziness is caused by severe carotid artery stenosis, and the nature and degree of stenosis in the carotid artery can be effectively detected through four methods: carotid artery color ultrasound, CT angiography, magnetic resonance angiography, and digital subtraction angiography, among which the most economical and applicable examination method is carotid artery color ultrasound.
Human blood is constantly flowing in the blood vessels, and some lipid components in the blood will be slowly deposited on the blood vessel wall, making the lumen smaller, just like a kettle, which deposits a large amount of scale, and it is inconvenient to pour water. The same is true for blood vessels, and those "scales" that gradually settle on the walls of blood vessels are called "vascular plaques". When plaque accumulates to a certain extent, it will hinder the normal flow of blood, causing carotid artery stenosis or even occlusion, dizziness, tinnitus, insomnia, memory loss, etc., which will lead to insufficient blood supply to the brain, which may cause stroke and even life-threatening.
Carotid artery stenosis can have no symptoms in the early stage, but patients with carotid artery disease can suddenly have a stroke without any warning, manifested as hemiplegia, aphasia, etc. Some patients may have some premonitory symptoms before this, called transient ischemic attack, which last for a few minutes to a few hours and can gradually resolve on their own, these transient aura symptoms mainly include:1weakness, numbness, or tremor in one limb; 2.limb immobility; 3.Blurred vision in one eye (many describe this feeling as a dark shadow in front of your eyes); 4.Slurred speech.
People over 45 years old, with high blood pressure, hyperlipidemia, diabetes, obesity, long-term smoking and drinking, family history of cardiovascular disease, and unstable angina pectoris, are particularly prone to plaque, and it is recommended to go to the hospital for a simple examination.
