"Doctor, you say, do I really have to put a heart stent?"
Lao Li is almost fifty years old, and his body is usually quite tough, but recently he feels stuffy in his chest, and his breath is not enough. When he went to the hospital, the doctor suggested that he have a heart stent.
But Lao Li heard that he didn't have this kind of surgery now, and he was so entangled in his heart, he was really afraid that if he put a stent in it, he would become half a waste.
"Doctor, you say, if I put a bracket, will it collapse?" Lao Li was quite worried.
The doctor smiled and said, "Lao Li, don't worry too much. Those rumors are nonsense. Medicine is always improving, and new technologies are popping up one after another. Heart stent surgery, not as scary as you think......"
After listening to the doctor's words, Lao Li felt a little more comfortable, but at the same time he was more curious. What is cardiac stent surgery like today, and what is the difference between new technologies?
01
Cardiac stent surgery, also known as coronary intervention, has been widely used in clinical practice since the 80s of the last century.
The principle is to implant a metal stent into a narrowed or occluded coronary artery, and use the power of the stent to open the blood vessel and restore the blood supply to the heart muscle.
This technology has been hailed as a major milestone in the treatment of heart disease, saving countless patients on the verge of death.
However, the exploration of medicine never stops. With the continuous progress of science and technology, a series of new technologies have sprung up.
Among them, the image-guided minimally invasive surgical technology provides doctors with more accurate surgical navigation through advanced imaging equipment, such as intravascular ultrasound and optical coherence tomography, making the surgical process more accurate and safe.
Another major breakthrough in recent years is bioresorbable stents, which can be gradually absorbed by the body for a period of time after implantation, thus avoiding the risk of long-term foreign body retention.
The emergence of new technologies not only reduces the risk of surgical complications, but also improves the quality of life of patients to a certain extent.
For example, the use of bioresorbable stents avoids the need for patients to take anticoagulant drugs for a long time, and reduces the impact of drug side effects on patients' lives.
02
Cardiac stent surgery is an important part of the history of heart disease treatment.
Over the past few decades, it has won the hearts of doctors and patients with its unique efficacy and relatively small trauma. However, any technique has its limitations, and cardiac stent surgery is no exception.
In the process of long-term use of cardiac stents, some problems are gradually exposed. The most common of these is the re-narrowing of the inside of the stent, the so-called in-stent restenosis.
This is due to the response of the blood vessel wall to injury and intimal hyperplasia after stent implantation. In addition, stent thrombosis is also a problem that cannot be ignored, which can lead to serious complications such as acute myocardial infarction.
Despite these problems, cardiac stent surgery remains one of the most effective treatments for acute myocardial infarction. At the same time, the medical community is constantly exploring and refining this technology in order to reduce the incidence of complications.
03
With the continuous development of medicine, more and more innovative technologies have emerged in the field of cardiac treatment. These new technologies pose challenges to traditional cardiac stent surgery, while also opening up more treatment options for patients.
Image-guided minimally invasive surgery has attracted a lot of attention for its high precision and high safety.
This technology provides doctors with real-time surgical navigation through advanced imaging equipment, which greatly improves the accuracy and success rate of surgery. At the same time, minimally invasive surgical techniques also reduce surgical trauma and recovery time, resulting in a better treatment experience for patients.
Biodegradable stents are another new technology that has attracted much attention. The stent is gradually absorbed by the body after implantation, thus avoiding the risk of long-term foreign body retention.
Biodegradable stents have better biocompatibility and lower complication rates than traditional metal stents.
In addition, drug-eluting stents are an important new technology. The stent is coated with a drug that provides a sustained release of the drug to prevent the blood vessel from becoming clogged again.
Compared with traditional bare-metal stents, drug-eluting stents can significantly reduce the risk of in-stent restenosis and improve patient survival and quality of life.
The emergence of these new technologies not only brings more treatment options to patients, but also poses a challenge to traditional cardiac stent surgery.
However, each technology has its advantages, disadvantages, and scope of application. When choosing a treatment, the doctor needs to conduct a comprehensive evaluation based on the patient's specific situation to ensure that the most suitable treatment option for the patient is selected.
At the same time, we need to continue to pay attention to the development and application of new technologies in order to provide better medical services to patients.
