..."And because these severely blocked areas are not in good locations, and there are also problems such as myocardial bridges, simply implanting stents can no longer solve the problem, so our plan is still to directly perform vascular implantation and bypass surgery to bypass the These severely blocked lesions will directly supply blood to the terminal blood vessels, which will completely solve the blockage problem in these locations.

As we all know, whether it is stent implantation or vascular implantation bypass surgery, it is the most conventional, safest and currently the best treatment option for the treatment of coronary heart disease and myocardial infarction. But they will also bring some problems, such as the need to take long-term medication after surgery, and long-term use of these drugs will cause some damage to the body, such as damage to liver and kidney function, and for example, long-term use of anticoagulant drugs will cause patients to of platelets decreased.

If the patient is injured in this way, it will cause excessive bleeding and the bleeding cannot be stopped in time, which may be life-threatening in severe cases.

Therefore, Mr. Zhang and his family still have some doubts about such a treatment plan. Coincidentally, we also learned that Haoyu Technology Company has been engaged in research in the field of medical technology and has developed many advanced medical technologies.

And there are experts from the Linghu Medical Research Center of the Affiliated Hospital of Air Force Medical College here. We also want to hear your opinions and suggestions. "

After listening to Director Bai's introduction, Director Tong nodded, and then said: "Your hospital's treatment work is very good. At this stage, it is most important to stabilize the patient's condition and maintain the patient's vital signs.

Judging from their introduction later and the relevant examination reports that came successively, the patient's condition is optimistic. There were very few open areas in the patient's heart, more than a dozen, of which no seven were the oldest, and only two of them caused the myocardial infarction.

In your opinion, at this stage, retrograde stent implantation cannot completely solve those problems, and retrograde vascular implantation and bypass surgery are necessary.

Although the patient's cardiac myocardium was damaged and the blood vessel blockage was relatively minor, at the latest moment, you still recommended that the patient directly undergo the implantation of a smart bionic artificial heart.

Although the success rate of smart bionic artificial heart implantation is very low, the preoperative survival treatment of patients is also very poor. But it is a man-made thing after all, and it is naturally not as bad as your original heart.

The seventh method is also very complicated. This is not about implanting micro-robots inside the patient's coronary arteries. The role of those micro-robots is not to constantly decongest the vascular network to ensure smooth flow of the vascular network. "

And you didn’t answer one or two that time, but directly established a seventh blood supply channel for the patient’s terminal myocardial tissue. In this way, you cannot increase the blood supply to the terminal myocardial tissue. Even if one blood vessel is blocked for a long time, it will still be blocked. There is no other blood vessel supplying blood, thus avoiding the occurrence of myocardial infarction and angina pectoris.

After listening to Director Tong's introduction, Director Bai, Vice President Huang and other doctors at Mining Group General Hospital all showed expressions of amazement. Those eight plans are really eye-opening for us, and the benefits cost money. First of all, the first set of treatment plans is relatively conventional. The first is to use the biodegradable stent that is newly launched in your country to implant and expand the wide areas of the heart, thereby causing the blood flow in those locations to be smooth.

And that is the first way to save life, it is a last resort, and it is always the best choice. "

Although there are not enough case reports to confirm the findings of that study, it illustrates a problem. Of course, the intelligent bionic artificial heart will have no emotions, but it may also destroy the patient's original emotional personality and behavioral habits to a certain extent.

At that point, Director Tong paused for a moment, and then continued: "Before relevant discussions, you have a total of eight treatment plans.

Before treatment, the patient's pre-healing lifestyle was still very poor, and it was basically impossible to return to normal human levels. "

As a result, the stent may remain in the blood vessel and be buried in blood vessel secretions for life, making it impossible to remove it.

If you look at the two myocardial bridges, you must undergo bypass surgery. The nanovascular stent developed by Haoyu Technology cannot solve that problem.

At the same time, on this basis, you cannot use biological stem cell tissue to repair the patient's damaged vascular tissue and myocardial tissue to restore heart function.

Of course, that treatment plan also requires degenerative repair of the patient's undamaged myocardial tissue. It cannot use stem cells to degenerate and repair, nor can it use 3D bioprinting technology to degenerate and repair.

As for the lifelong medication problem before surgery, there is no solution to that. The first is to reuse biological agents. Such biological agents cannot replace drugs to play an anticoagulant role. In this case, there will be too few toxic side effects and cannot be used for a long time.

"As for the eighth treatment plan, it is more conservative. In this period, stents are used to regenerate and expand the blood vessels that are not blocked in the patient's body, thereby ensuring the smooth flow of those blood vessels.

Having said that, Director Tong glanced at the reactions of everyone in the video screen, and then continued: "The seventh set of treatment plans is also more thorough. This is not using bio-3D printing technology to print out the patient's bruises one-to-one. The blocked coronary artery tissue is then degenerated and replaced with an implant. In this way, the patient has a new tubular artery blood supply network.

In addition, using stem cell therapy, you will regenerate stem cell treatment and repair the myocardial tissue damaged by the patient's infarction, thereby restoring the firepower of that part of the myocardial tissue and improving heart function. "

The smallest disadvantage of that kind of biodegradable stent compared to the original metal-coated stent is that it cannot degrade and melt. It only needs to be implanted into the body, so that two or eight years ago, those stents will completely degrade and integrate into the blood vessels, and form a stable support structure in the blood vessels to maintain the smooth flow of blood vessels.

Because the materials needed to print blood vessels are derived from the patient's own blood vessel wall cells, any rejection reaction will not occur. The patient needs to take medication for life, and the curative effect is significant before treatment.

Based on this, you will use bio-3D printing technology to extract the patient's blood vessel wall cells to print artificial blood vessels, and then use those artificial blood vessels to implant bypass surgery for the patient's degenerated cardiac blood vessels.

And there is no data and research showing that the human heart is also an emotional organ, which can reflect the patient's personality and emotions to a certain extent. For example, there are very few allogeneic heart transplant surgeries in the country before the patient's personality and even some behavioral habits have undergone very small changes, and that change will be close to the donor's personality.
