Can the heart stent be removed later?

If a patient with coronary heart disease has a heart stent, can the stent be removed in the future? This is a topic that many friends with coronary heart disease and family members of coronary heart disease patients are very concerned about. Today, Dr. Zhang will give you a detailed introduction to this knowledge.

You can't. Instead of removing the blockage, the stent compresses the blockage. If you take it out, it will be clogged again, and at this time, symptoms of diseases such as palpitation and chest tightness will be **.

After the stent is implanted in the coronary artery, the patient will be very concerned about how long the stent will last. Stent implantation technology has been around for more than 20 years. It's unclear how long the stent lasts, but it is generally covered by the intima of the blood vessel within a year of stent implantation, becoming part of a normal blood vessel.

First of all, why do patients with coronary heart disease have stents? Actually, it's basically because the coronary arteries have a fairly severe stenosis. In general, coronary artery stents are required if the stenosis of coronary atherosclerotic lesions is greater than 75% and there is typical myocardial ischemia.

The stent is implanted and cannot be removed. These stents tend to end up entering"Endothelial layer", which is the endothelial layer that wraps around the stent, which means that the stent is connected to the arteries in the body. If this is the case, it is almost impossible to remove the bracket.

So, what if something goes wrong with the stent?

Cardiac stents. Can you put them in and out of them? Doctors say differently.

In fact, the vast majority of patients with coronary heart disease will not have major problems after implanting cardiac stents, as long as they insist on taking medication and go to the hospital for regular check-ups. However, a small percentage of patients develop stent restenosis. At this time, different methods such as stent replantation, drug balloon, coronary artery bypass, and drug conservatism** are generally considered**.

Of course, it should be targeted according to the actual situation of different patients.

Cardiac stents. Can I put it in and take it out? The doctors tell a different story.

I just want to tell my friends that once a stent is implanted, the chances of it being removed are very, very small. But if something goes wrong with the stent in the body, it's not irreparable. Modern medicine has many ways to help you solve your problems.

After the traditional metal heart stent is implanted, the endothelium of our blood vessel will slowly cover the stent, so it is generally impossible to remove it. However, there are also absorbable heart stents, which are made of biodegradable materials and will slowly degrade after a period of implantation, and will not remain permanently in the body. I know that the first one made in China is Lepu's bioresorbable stent, which has been implanted for about 3 years, and all of it has been degraded, and the blood vessels have returned to normal.

Cardiac stents. Once successfully implanted, it is usually impossible to remove it, and after pressure dilation, the stent and the coronary artery fit tightly and become part of the blood vessel wall, and the endothelium wraps around the stent in the continuous formation process, and finally the blood vessel and the stent are tightly fitted. It is usually not possible to remove the stent after the stent implantation surgery because the tight fit has made the stent and the blood vessel an inseparable part of each other, so if restenosis occurs after stenting, residual or new lesions can be improved by medications**, balloon dilation, and suspension.

Myocardial. If the patient has a severe, narrow or even obstructed coronary artery, coronary angiography should be performed.

If iodine oil contrast establishes the site of the lesion and the extent of its invasion, minimally invasive cardiovascular surgery is required.

Interventional surgery. Minimally invasive interventional surgery includes balloon dilation surgery** and stent implantation surgery**, the actual operation procedure of stent implantation surgery** is to carry out the pre-dilation of the balloon according to the narrow lesion, and then implant the stent into the place where the capillary is to be dilated and expanded after the lesion is sufficiently solved.

Coronary stents.

Whether it will be blocked again after implantation is indeed a problem that patients and physicians are very concerned about, to be honest, it is possible to be blocked, but the probability of occurrence is not high, including the following two probabilities.

The first condition is stent thrombosis.

Coronary artery stents are a kind of dirt for the body, and the dirt is likely to arouse the body's coagulation function during the blood night, and then produce venous thrombosis.

This is why after stent implantation surgery, antithrombotic treatment should be strengthened, and aspirin is generally used.

Plus another antithrombotic drug, such as ticagrelor or clopidogrel dual antithrombotic therapy. Even if it does, there is still a small chance of thrombosis, which usually occurs in the early stages of stent placement.

The second situation is that the coronary arteries are narrowed: coronary artery stent implantation surgery** does not actually deal with the cause of myocardial infarction, so there is a high probability that the coronary arteries will redevelop after the stent implantation surgery, such as excessive growth of smooth muscle cells, and the transformation of atherosclerotic spots will cause the coronary arteries to become narrower, which generally occurs in the middle and late stages of stent implantation.

Coronary stents are a powerful way to treat more serious myocardial infarctions, and it is not possible or unnecessary to remove them after stent implantation. For coronary stents that have already been implanted, what we need to do is to minimize the re-blockage of the coronary arteries, such as the formation of blood clots and re-narrowing. The antiplatelet resistance can be strengthened according to the selection of appropriate stents.

Healing, manipulation of blood pressure values, blood sugar levels, blood sugar, quitting smoking, ****, etc. If you have done the best you can do, and the coronary artery is still blocked, you don't have to worry too much, you can defeat the enemy with one move, and you still have some corresponding ways to make up for it, such as balloon enlargement, re-implantation of stents, coronary artery bypass grafting, etc.

It is not possible to remove the stent after it has been implanted. The stent does not remove the blockage, but compresses it, and if it is removed, it will be blocked again, and there may be repeated symptoms of coronary heart disease such as palpitation and chest tightness.

After the patient implants a stent in the coronary artery, he will be very concerned about how long the stent can last, the implanted stent technology has a history of more than 20 years, and how many years the stent can be maintained, in fact, it is not very clear, but after the stent is implanted, it will be completely covered by the vascular intima within one year and become a part of the normal blood vessel.

The stent should not be taken out in the future, because this stent is very important for people with coronary heart disease, so we must look at it rationally and do not speculate.

People who have had a heart stent for coronary heart disease cannot have the stent removed in the future.

I don't think I can take out the stent in the future, because after doing a heart stent once, the stent must stay in the heart forever, so that it can be healthy.

No, this surgery is irreversible, and once you start to do stents, you need to maintain them regularly so that you can protect yourself.

Like the traditional metal heart stent, after it is implanted, our vascular endothelium will slowly cover the stent, and it is generally impossible to take it out. However, there are also degradable stents made of degradable materials, and the first degradable stent in our country was available in 2019, which is Lepu's bioresorbable stent. After it is implanted in the blood vessels, it will be completely degraded in about three years and will not remain in the blood vessels permanently.

It should be able to be taken out, because the stent also has a lifespan, so it must involve the replacement of the old and new stents.

There is no way to take it out later, because it has grown with some blood vessels in the heart.

With current medical technology, it is very difficult to remove the stent, and it is not necessary at all.

It cannot be taken out. Once the heart stent is made, it will be fixed in the body.

I don't think so, if the stent is taken out, you will die. In addition, it is necessary to be careful not to do strenuous exercise.

You can take it out, but if you take it out, your lifespan may be cut by more than half. Because it's mainly a brace to keep you alive.

Cardiac stent surgery is a procedure performed in the hospital after the onset of many heart disease patients. The success of cardiac stent surgery does not mean that the patient's heart disease has been completely completed, so the patient must follow the doctor's instructions to take medication on time after cardiac stent surgery, otherwise there may be a risk at any time, which will damage the patient's life and health. Today, I would like to tell you what you can't do after heart stent surgery.

Generally, the doctor will ask the patient to go back and take the medicine on time after the operation, but some heart patients feel that they have finished heart surgery and are fine, so they stop the medicine privately. Insisting on taking the medicine prescribed by the doctor after the surgery can unblock the blood vessels and ensure the efficacy of the surgery. However, many heart disease patients stop taking medicine because they feel that they don't have any special feelings, so they feel that taking medicine is useless.

If the patient stops the medicine privately shortly after being discharged from the hospital, the heart disease of the body cannot be improved, so the patient who undergoes surgery still has to take medicine for a long time according to the doctor's instructions even after the operation, and some patients even have to take medicine for life to prevent the onset of the disease.

Many patients find that they have recovered better after the operation, without any uncomfortable symptoms, but they feel that they have become **, so they do not take care of their body anymore, and do not follow the doctor's instructions to go for regular check-ups. Generally, when the cardiovascular disease is stable, the patient's body will not have any uncomfortable symptoms, but this does not mean that there is no damage to the human body, sometimes the human body has no symptoms, and the body's blood circulation will also be affected, so the patient also needs to adhere to the doctor's instructions and go to the hospital regularly for reexamination.

After cardiac stent surgery, patients must pay attention to a healthy life and avoid bad lifestyle habits and rest. Go to bed on time every night, don't stay up late, go to bed early and get up early, quit smoking and drinking.

Nowadays, with the development of society, China's medical technology has been greatly improved, and many new technologies have emerged, including cardiac stenting. For many patients with coronary heart disease, it gives them hope for life. As a result, more and more people are adopting this technology.

So, what is cardiac stent surgery? What are the precautions after heart stent surgery? Most importantly, can I fly after surgery?

In medicine, cardiac stent surgery also has a name, that is, coronary artery stent implantation, which uses the means of vascular puncture to place a balloon catheter into the narrow blood vessels of the human body, so that the narrowed blood vessel wall can be opened, so that the abnormal blood vessels caused by the disease can be restored and unblocked, and the acute occlusion of the coronary artery can be prevented.

After the heart stent surgery, the patient's body is still in a weakened state. Therefore, do not exercise vigorously. In addition, the most important thing is to pay attention to the diet, not to eat too meaty, salty food, to be light.

In addition, quit smoking and avoid alcohol. Because drinking and smoking are easy to destroy drugs and form vascular plugs, in severe cases, it will lead to life and health.

However, after the surgery, flying is allowed and there are no special contraindications. However, due to the different patients, their physical conditions, heart function, and coronary artery opening status are also different, so when taking the plane, the risk of cardiovascular events is also different.

If a patient with coronary heart disease is flying, the patient may have mild hypoxia symptoms due to the influence of high air pressure. For ordinary people, apart from some physical discomfort, it will not bring much of a problem.

However, for patients with coronary heart disease, there is a high probability of myocardial ischemia. At the same time, because it is in the high altitude, even if the onset of the disease cannot be timely **, the consequences are unimaginable. In this regard, when choosing to fly, you must be cautious and carefully consider your own situation.

Especially for those patients who have already had heart stent surgery, it is important to consult a doctor in advance to consider their own situation and under what circumstances the surgery will be performed. Because stents are placed in different conditions, the condition of the myocardium and the condition of the heart function can be completely different.

If the patient feels that his condition is relatively stable and there are few coronary vascular lesions, blood flow returns to normal after the stent is placed. At the same time, there is no angina pectoris, and it is possible to fly within 14 days after the operation. However, just in case, it's important to travel with a companion and have relevant medications, such as nitroglycerin, ready.

Be sure not to exercise vigorously, don't smoke and drink, don't overeat, don't be in negative emotions for a long time, and then be sure to do a good job of prenatal checkups, and never drink medicine.

Running, doing sit-ups, planks, skipping rope and swimming are not things you can't do.

No strenuous exercise, no mood swings, no smoking or alcohol. Can't overeat. Sadness must not arise. None of these conditions are conducive to postoperative recovery.
