All say that cerebral infarction thrombolysis treatment is the best, and can achieve immediate results without any sequelae. So why did the doctor not lysis me for thrombosis when I was diagnosed with cerebral infarction? Some people also say that thrombolysis treatment has great side effects and is prone to bleeding. Who should I listen to? In order to explain these issues clearly, interested friends suggest that after reading it, you can not only understand the relationship between cerebral infarction and thrombolysis, but also at the end, tell you how to fundamentally prevent cerebral infarction.
First of all, we need to know what cerebral infarction is. It is actually very simple, that is, the arteries that supply blood to the brain are blocked. Why are good blood vessels blocked? The most common cause of
is arteriosclerosis. Our color ultrasound diagnosed carotid artery plaque or thickening of the internal media, which is the manifestation of atherosclerosis in different periods. Not only in the carotid artery, but also in large and medium-sized blood vessels throughout the body, such as cerebrovascular, heart, coronary blood vessels. If the plaque is too large, it will squeeze the space of the lumen inward, causing blood vessel stenosis. However, the plaque is not a thrombus. The plaque is something that grows inside the blood vessel wall. The main component is oxidized low-density lipoprotein cholesterol, which is a clump composed of blood lipids and some phagocytocytes. Moreover, plaques grow very slowly and generally do not cause acute occlusion of blood vessels. In addition, there is currently no drug that can dissolve plaques, but statin can make it more stable, and if the LDL cholesterol can be pressed very low, the current view is that some plaques may become smaller or even disappear.
Only when the unstable arterial plaque ruptures, that is, the inner wall of the blood vessel is damaged, the blood coagulation components, platelets , fibrinogen , etc. will instinctively gather, and bind red blood cells and other cells in a very short time to quickly form thrombus. This is called thrombus. Furthermore, blocking the blood vessel lumen and causing infarction. Blocking the cerebral blood vessels is called cerebral infarction, and blocking the coronary blood vessels of the heart is called myocardial infarction. At this time, drugs such as
aspirin can inhibit platelets to a certain extent and prevent them from forming thrombus. However, if the blood clots are not stopped, the blood clots will still be formed and the blood vessels are blocked. What should I do? A special type of medicine can be used to dissolve the formed blood clots. However, there are several problems here. First, thrombolysis can only be performed within 4.5 hours of just cerebral infarction, and the earlier the better. Why?
Because brain cells are very sensitive to ischemia and hypoxia, once the time exceeds a certain period of time, nerve cells will die irreversibly, and it is meaningless to open blood vessels at this time. In addition, not only nerve cells will die, but blood vessel cells will also be damaged. Opening blood vessels after more than 4.5 hours of time window can easily cause bleeding. Therefore, thrombolysis requires very strict time requirements, that is, thrombolysis only dissolves the thrombus in the blood vessel. Only when the blood vessel is just blocked can a large number of nerve cells be avoided. Once time passes, the nerves are dead, and it is meaningless to open the blood vessels again. The significance of thrombolysis in treating cerebral infarction is that the blood flow is restored before the cerebral infarction is formed, so time is very important.
Second, even within the specified time, not all patients can meet the thrombolysis standards. thrombolytic drug is a drug that can degrade blood clots, which will change the balance of coagulation function throughout the body. If the patient has cerebral hemorrhage in the past, or has just undergone surgery recently, and the wound has not healed, or has recently experienced bleeding in the digestive tract and other parts of the body, it cannot be thrombolysis because it may cause bleeding risks.
Third, although thrombolysis is currently the relatively optimal treatment plan for acute cerebral infarction , it cannot achieve cure the disease by medicine. Even if the blood clots can be completely removed, ischemia within a few minutes or even hours often leaves the patient with certain symptoms. Therefore, for ordinary people, you should remember one word quickly when treating cerebral infarction.When you find that your arms and legs are numb, weak, and you can't speak clearly, and your mouth is crooked and your eyes are slanted, don't worry about it. You should go to the hospital as soon as possible to evaluate whether you should be thrombolysis and whether you can be thrombolysis can be left to a professional doctor. If it is acute cerebral infarction, if it reaches one minute earlier and thrombolysis is one minute earlier, it can save tens of thousands of dying nerve cells, which may reduce the sequelae and even save lives. Cerebral infarction itself is the ultimate serious consequence of the long-term existence of problems such as smoking, drinking, and obesity.
Therefore, if you want to truly prevent cerebral infarction from the root of the disease, remember the following sentences: Diversified diet, moderate exercise, reasonable work and rest, quit smoking and limit alcohol, regular physical examinations, and seek medical treatment in time when the three highs are found. If the doctor recommends taking medication, insisting on taking medication, and having regular reviews to ensure that blood pressure, blood sugar and blood lipids are stable in a reasonable range for a long time.
