Carotid stenosis symptoms Carotid stenosis is the narrowing of the lumen of the carotid artery due to atheromatous plaque in the carotid artery. When the carotid artery is narrowed, the brain also suffers from varying degrees of ischemia. The main manifestations are: dizziness, blackness in front of the eyes, with darkness, and brief loss of consciousness. Carotid artery stenosis examination: Once a patient has appealed symptoms, it is recommended to go to an outpatient clinic for a carotid ultrasound. If the ultrasound shows stenosis and reveals ulcerative plaque formation, it is necessary to follow medical advice for further examination. For specific diagnosis, CT angiography (CT angiography CTA) is gradually replacing arteriography as the gold standard for diagnosis. Carotid artery stenosis treatment: generally divided into surgical treatment, drug treatment, interventional treatment. Surgical treatment: The main treatment is carotid endarterectomy (CEA). Carotid endarterectomy is to restore the blood supply to the brain and eliminate the source of emboli in cerebral infarction by removing the thickened carotid intima-media atherosclerotic plaque. The operation has been carried out for many years and is relatively mature. The advantage of this operation is that the chance of re-stenosis after the operation is not high, generally less than 10% of re-stenosis occurs within one year. The cost of surgery: The cost of surgery at the Union Hospital is generally about 15,000 yuan. Carotid artery stenosis surgery: Patients with carotid artery stenosis >75%; or carotid artery ulcerated plaque need to receive surgery Medication: mainly antiplatelet therapy. Interventional treatment: mainly carotid stenting PTA carotid stenting How should recurrent stenosis after carotid stenosis be treated? Once the stenosis occurs again after surgery, the chance of re-operation is not very high, and generally only pharmacological treatment can be used. What information do I need to bring to the consultation at Concordia Hospital? If you come to Concordia Hospital and have had a CT angiogram before, please make sure to bring the films of the test. If you have not had a CT angiogram, you will need to bring the results of your most recent ultrasound.
