In modern medicine, stroke has become one of the important diseases threatening human health, with high disability and mortality rates that make people shudder. However, through scientific prevention and timely intervention, we can greatly reduce the risk of stroke. Among them, carotid ultrasound examination, as a non-invasive and convenient examination method, is known as a "warning device" for preventing stroke.
Stroke, commonly known as "stroke", is mainly divided into two categories: ischemic stroke and hemorrhagic stroke. Among them, ischemic stroke accounts for about 70% to 80% of all strokes. The formation of carotid atherosclerotic plaque and its resulting carotid stenosis is one of the important risk factors of ischemic stroke.
The human body has two main carotid arteries, located on both sides of the neck, which are the main sources of blood supply to the brain and head. Every time the heart beats, a large amount of blood flows through the carotid artery to the brain, providing it with the necessary oxygen and nutrients. Therefore, the health status of the carotid artery is directly related to the function of the brain and life safety.
Carotid artery ultrasound examination is a non-invasive examination method that uses high-frequency ultrasound to image blood vessels, which can clearly display vessel diameter, blood flow velocity, and the condition of the vessel wall. This examination method is not only safe and painless, but also easy to operate, making it the preferred means of evaluating the health status of the carotid artery.
Through carotid ultrasound examination, doctors can observe the thickness of the carotid intima. Under normal circumstances, the intima-media thickness of the carotid artery should be below 1.0 millimeter. If the thickness of the intima-media increases to more than 1.5 mm, it often indicates the presence of atherosclerosis. In addition, ultrasound can also detect whether there is plaque formation in the carotid artery. The nature of plaques is crucial for assessing the risk of stroke. Stable plaques typically have a smooth surface, uniform texture, and are not easily ruptured or detached; Unstable plaques, on the other hand, have a rough surface and uneven texture, which can easily rupture and form blood clots, blocking cerebral blood vessels and causing stroke.
Carotid ultrasound can also measure the degree of stenosis in the carotid artery. The more severe the stenosis, the higher the risk of stroke. Generally speaking, when the degree of stenosis exceeds 50%, active treatment measures such as medication, surgical treatment, or interventional therapy need to be taken to reduce the risk of stroke.
In addition to regular carotid ultrasound examinations, preventing stroke also requires starting from daily life details. Firstly, it is important to maintain good dietary habits by choosing low salt, low-fat, and high fiber foods, and avoiding excessive intake of salt and unhealthy fats. Secondly, moderate exercise is necessary to enhance cardiovascular function and promote blood circulation. In addition, it is necessary to quit smoking and limit alcohol consumption, and avoid unhealthy habits such as staying up late for a long time and overwork.
For populations with high-risk factors such as hypertension, hyperlipidemia, and hyperglycemia, it is even more important to strengthen monitoring and management, take medication on time according to medical advice, and have regular follow-up visits to ensure effective control of the condition.
Carotid ultrasound examination can not only detect carotid artery lesions early and provide a basis for preventing stroke, but also evaluate and monitor the treatment effect. For example, for patients receiving medication treatment, regular follow-up of carotid ultrasound can be used to determine whether the plaque is stable and whether the degree of stenosis has improved, thereby adjusting the treatment plan.
Carotid ultrasound examination, as a "warning device" for preventing stroke, provides us with an important means of early detection and intervention of stroke risk. Through scientific prevention and timely intervention, we can greatly reduce the incidence of stroke and protect the health of ourselves and our families. Let's start with the details of daily life, pay attention to carotid artery health, and stay away from the threat of stroke.
