Introduction
With increasing age, the elasticity of blood vessel walls gradually diminishes, making it easier for lipids to deposit and potentially leading to stenosis of the left vertebral artery. It is recommended to undergo regular vascular examinations and reduce intake of high-fat foods in daily life to delay the process of vascular aging. Congenital narrowing or abnormal course of the left vertebral artery can easily cause hemodynamic changes, leading to stenosis.
Common causes of left vertebral artery stenosis may include aging, vascular developmental abnormalities, atherosclerosis, hypertension, cervical spondylosis, and arteritis. It is usually treated through general therapy, medication, physical therapy, and other methods. If any abnormalities occur, timely medical attention is recommended. Detailed analysis is as follows:
1. Aging: With increasing age, the elasticity of blood vessel walls gradually decreases, making lipid deposition easier, which may lead to left vertebral artery stenosis. Regular vascular examinations are recommended, along with reduced intake of high-fat foods in daily life to delay vascular aging.
2. Vascular developmental abnormalities: Congenital narrow diameter or abnormal course of the left vertebral artery may cause hemodynamic changes, leading to stenosis. Excessive neck movement should be avoided to reduce vascular compression, and regular monitoring of vascular function is recommended.
3. Atherosclerosis: Lipid deposition on the wall of the left vertebral artery forms plaques, leading to lumen narrowing, often accompanied by symptoms such as dizziness, limb numbness, and blurred vision. Patients may take aspirin enteric-coated tablets, rosuvastatin calcium tablets, clopidogrel bisulfate tablets, and other medications as prescribed to stabilize plaques and prevent progression.
4. Hypertension: Long-term elevated blood pressure damages the endothelium of the left vertebral artery, causing vascular wall thickening and lumen narrowing, often accompanied by symptoms such as headache, head fullness, and palpitations. Patients may use amlodipine besylate tablets, telmisartan tablets, indapamide tablets, and other medications under medical guidance to control blood pressure and reduce vascular damage.
5. Cervical Spondylosis: Osteophyte formation or intervertebral disc protrusion in the cervical spine may compress the left vertebral artery, resulting in lumen narrowing, often accompanied by neck and shoulder pain, worsening dizziness, and upper limb weakness. Patients may use celecoxib capsules, eperisone hydrochloride tablets, Jing Shu granules, and other medications as advised by doctors, combined with physical therapies such as cervical traction.
In daily life, a low-salt and low-fat diet should be maintained, appropriate aerobic exercise performed, weight controlled, and prolonged head-down or fixed neck postures avoided. If recurrent dizziness, limb weakness, or other symptoms occur, timely medical evaluation is necessary to determine the degree of stenosis and receive targeted treatment.
