Instructions for carotid arteries
Vital carotid arteries
The carotid artery is one of the main channels for blood supply to the brain and is located at the bifurcation of the aorta. If you press hard, on the one hand, the carotid artery will form a baroreflex, which may cause the heart rate to slow down, blood pressure to drop, and even cardiac arrest in severe cases. On the other hand, excessive compression of the carotid artery can also lead to life-threatening embolism.
Carotid Artery FAQ:
Atherosclerotic atherosclerotic plaque
Atherosclerotic plaque, commonly known as arteriosclerosis, accounts for more than 95% of the entire carotid artery disease.
Even if the atherosclerotic plaque is relatively stable, if it is large and occupies most of the lumen space, it will cause insufficient blood supply to the human brain and bring danger.
When blood flows through the uneven lining of blood vessels, platelets in the blood are activated to form blood clots. The atherosclerotic plaque itself may also rupture and bleed or fall off. The sloughed plaque or blood clot travels with the bloodstream and can lead to a stroke.
Contraindications for carotid atherosclerosis
The blood of patients with hyperlipidemia is thicker and slower, and the low-density lipoprotein in the blood is easy to precipitate in the damaged part of the vascular endothelium, thereby starting the process of arteriosclerosis. Vascular endothelium is easily damaged in patients with hypertension and hyperglycemia, which creates opportunities for arteriosclerotic lesions. Nicotine in cigarettes can cause severe damage to the vascular endothelium. At the same time, smoking can cause vasoconstriction, thereby aggravating carotid artery stenosis caused by arteriosclerosis.
Experts remind: Carotid arteriosclerosis is also related to age. Blood vessels also age with age.
Fault judgment of carotid arteriosclerosis
Experts remind: If you have long-term blurred vision, unwillingness to express, slow walking, and always feeling depressed, it may also be a manifestation of insufficient blood supply caused by carotid artery stenosis, and you need to seek medical treatment in time to clarify the cause.
Carotid arteries are repaired and maintained in this way
Advanced Care: Carotid Ultrasound
Through carotid ultrasonography, plaques can be found and the condition of the carotid arteries can be understood, and this inspection is non-invasive, convenient and can be repeated.
Don’t be nervous if you find plaque. Everyone’s height and weight are different, and the thickness of blood vessels is different. Plaques of the same size have different meanings for different people. The degree of carotid stenosis can be reflected by blood flow velocity.
Medication
Patients with moderate carotid artery stenosis should preferably have a carotid ultrasound every six months, in addition to drug therapy.
1. Use anti-platelet aggregation drugs such as aspirin or Plavix to prevent platelets from forming blood clots;
2. Scientific medication to control blood pressure, blood lipids and blood sugar.
Surgical treatment
Surgical treatment is divided into carotid atherectomy and carotid stent implantation.
Patients with carotid artery stenosis less than 50% and asymptomatic are not suitable for surgical treatment.
Amaurosis transient, sudden aphasia, sudden hemiplegia, even if the carotid artery stenosis is less than 50%, requires early intervention.
Stenosis of the carotid arteries of more than 70%, even if asymptomatic, requires surgery.
