Myocardial infarction does not require stents, just pull out the thrombus? Experts refute rumors: don't be delusional
At 3 o'clock in the clinic, a patient with acute myocardial infarction was sent at 120, and it was recommended that the patient be angiography immediately, b may need a stent if necessary!
But the family members disagreed with everything they said, saying that only the thrombus was drawn and the stent was not placed.
I say it's basically impossible, unless it's a special disease, most myocardial infarctions may require stents.
The family members took out their mobile phones and showed me a video, which was sent by a local station. The screenshots are as follows:
This is a recent video on the Internet about suctioning blood clots in the blood vessels. Aspirate the thrombus cleanly.
very beautiful and perfect!
Then the question arises, since the thrombus can be sucked out so cleanly, why do people still put stents on people, what a black-hearted doctor!
The family must think so, and it is understandable!
Because of the urgency of time, I can only tell him that there is no such device for clinical use in the world at present, and the best method is still a stent, and we must hurry up. As for the detailed explanation, I can tell you in detail after the operation.
In this way, the family agreed to the operation!
The people who made this so-called device actually don't know what a thrombus is, and they don't even know how to remove the thrombus.
For one, it's a device that doesn't exist at all.
Second, this is an animation made by a layman, just for grandstanding and attracting attention.
Third, people who do not understand thrombosis are excusable. If a doctor or a local station also forwards such animations, their hearts can be punished.
First of all, we have to know how the thrombus in the heart blood vessels is formed. Under normal circumstances, it is the atherosclerosis of the heart, which gradually aggravates and forms plaques. Once the plaque ruptures, a blood clot forms, and a blood clot inside a blood vessel is a thrombus.
Acute myocardial infarction occurs when a blood clot occurs in the cardiovascular system and the blood clot blocks the blood vessel. Then there will be a series of symptoms of angina, such as pain, and the risk of heart failure, and the risk of death. The first aid method is to open the blood vessels as soon as possible, and we simply think that the thrombus is cleared and it will be OK!
At present, the methods of removing thrombus include thrombolysis and stents. Thrombolysis is simply understood as infusion. The thrombus is melted through drugs, and the thrombus is melted, then the blood flow will be restored, and the large thrombus will become a small thrombus and a small thrombus until it disappears. , within 3 hours of acute myocardial infarction, the best thrombolytic drug, the thrombolytic effect is very good, but after 3 hours, the effect is significantly reduced, and it is difficult to dissolve again. However, thrombolysis is only through thrombolytic drugs to dissolve the thrombus blocking the blood vessel and restore the blood flow to normal. This is called success. It cannot achieve the clean effect of removing all thrombus immediately.
Can that pull the thrombus out? can!
For patients with heavy thrombus, the thrombus can be sucked out through a suction catheter, but thrombus is a blood clot. If you think about the blood clot staying in the blood vessel, it is not so honest. When the catheter touches the thrombus, the thrombus will be broken. Many small thrombi will run to the far end of the blood vessel, and sometimes even large thrombi will flow with the bloodstream. Our current thrombus aspiration technique, the so-called successful aspiration, also extracts some large thrombi.
There is another problem that must be explained. Recent studies have shown that thrombus aspiration does not bring more benefits to patients with acute myocardial infarction. Simply put, patients who have thrombus aspiration are not as good as those who do not. Therefore, Current guidelines do not recommend routine thrombus aspiration unless the thrombus is particularly severe.
Therefore, for acute myocardial infarction thrombus, thrombolysis can only dissolve the thrombus, but cannot remove the thrombus; suction thrombus can only extract part of the thrombus, which is difficult to completely remove, and the suction effect is not good.
So why not use this kind of high-tech just mentioned? Can this high-tech suction clean the thrombus?
that is because:
When the catheter enters the blood vessel and encounters a thrombus, the thrombus will not be so obedient, the thrombus will be broken, and at most only a part of the thrombus can be extracted.
The thrombus is not an independent thrombus. The thrombus is formed by the rupture of the plaque, that is, the predecessor of the thrombus is the plaque. Although a part of the thrombus can be pulled out, the fixed plaque is still in the blood vessel; it is not an animation demonstration The inside of the blood vessel is very smooth, just an independent thrombus. Even if the thrombus is drawn out, the fixed stenosis of the plaque still exists, which may affect the blood flow, and may also form a thrombus.
So we only have to use a balloon, inflate, squeeze the plaque away, make the lumen of the blood vessel larger, and then follow the same method to place a stent in the stenosis to stretch the stenosis and restore normal blood flow . Some people say that after the balloon is opened, the blood flow is restored and the stent is placed. That is because after the simple balloon expansion, 50% of the blood vessels will be occluded again, so the stent must be passed, and long-term drug treatment is required, and A healthy lifestyle can prevent further aggravation of plaque, prevent thrombosis, and prevent re-myocardial infarction.
And not at all, the animation is so whimsical!
