I hear people mention these words every day! What exactly are stroke , stroke, cerebrovascular disease, cerebral infarction, cerebral hemorrhage, etc.?
Chinese and Western medicine officials uniformly call this pathological phenomenon stroke. In English, stroke is called "stroke", which means being suddenly struck down by some force.
The clinical description of stroke refers to an acute onset, neurological deficit syndrome caused by local blood circulation disorder in the brain. The symptoms last for at least 24 hours, but symptoms that only last for a few minutes or a few hours should also cause high attention. The focal symptoms and signs caused by stroke are consistent with the blood supply area of the affected cerebral blood vessels. However, when diffuse brain dysfunction occurs, such as global cerebral ischemia caused by cardiac arrest , it does not fall into the category of stroke. .
In our country, due to different knowledge backgrounds, stroke has many names, such as "stroke", " cerebrovascular accident " and "cerebrovascular disease". The patient is confused, what disease do I have? In fact, they all diagnose the same disease. Because this disease comes quickly, is sinister, and changes rapidly, just like the wind in nature, "good deeds are changeable", traditional Chinese medicine calls this type of disease "stroke." Because the disease occurs due to an accidental cerebrovascular accident, the onset is sudden and unpredictable, so it is also called "cerebrovascular accident". Western medicine calls it "cerebrovascular disease."
I hear people mention this word every day! What exactly is a stroke?
The blood vessels that supply blood to the brain originate from the aorta, and there are mainly four.
One of the most important causes of stroke One is that the cerebral artery is blocked, but the doctor wants to check whether there is any disease in the carotid artery. Why? The four arteries in the neck (the two carotid arteries in the front and the two vertebral arteries in the back) connect the heart and the cerebral arteries. Although the head is at the top and the neck is at the bottom, these neck arteries are the upstream arteries leading to the brain tissue. We can collectively call them carotid arteries. If the wall of one or more arteries in the carotid arterial trunk looks like an aging water pipe. There is also a lot of rust (atherosclerotic plaque) in the chest. Once these plaque fragments fall off, they will enter the cerebral arteries along the blood flow and cause cerebral artery blockage. In addition, the lumen of the cervical arterial trunk will become narrowed. To a certain extent or occlusion, its downstream (cerebral artery) will not receive enough blood supply, resulting in cerebral ischemia or cerebral infarction. Therefore, stroke patients must check whether there is an artery in the upstream carotid artery. Atherosclerotic plaques and their patency.
I hear this word mentioned every day!
Plaques form in arteries and cause blood vessel stenosis.
So are there any methods that can help us detect these stenoses in advance? What about the "blockage" of arteries?
In fact, simple arterial vascular ultrasound can achieve the purpose!
Neck ultrasound includes carotid artery ultrasound and vertebral artery ultrasound. Neck ultrasound is simple, non-invasive, and has good imaging. Clear and good resolution. It can not only accurately determine the degree and scope of carotid artery stenosis, but also determine the nature of the plaque, which is helpful for confirming carotid artery embolism and what treatment measures should be taken in the next step. Valuable basis. Vertebral artery ultrasound can also determine whether there is lumen stenosis in the initial segment and cervical segment of the vertebral artery, and whether there are surgical indications for high-risk groups such as hypertension, smoking history, diabetes, and hyperlipidemia. It is necessary to perform cervical ultrasound to detect atherosclerotic plaques early, and early intervention and treatment are of greater significance to the prevention of ischemic stroke
