It is said that DK-crush technology was studied by Mr. Huang in great detail, and this is the first time it has appeared in front of the world.

This new technique has appeared for the first time, and there must be countless incomplete areas.

For example, the crush technique has been modified countless times, the Reverse Crush technique, Step Crush technique, Mini Crush technique, and finally the classic crush technique.

After countless doctors studied and polished it, they took shape little by little.

All the technical details Zhou Congwen, who was standing on the podium, told very well, and Zhang You couldn't find any problem for a while.

Even though he subconsciously used the idea of ​​finding faults to listen, he couldn't find out what was wrong with Zhou Congwen's words.

This...is impossible!

The more Zhang You listened, the more confused he became. The more Zhou Congwen explained, the more confused he became.

It’s not that I can’t understand the technical details that Zhou Congwen said, but that this detail is too detailed and meticulous, so that Zhang You feels like he is eliminated by the world and feels like he is weak all over when facing geniuses.

Is it because the provincial capital is too closed that I have not opened my eyes to see the world and have been abandoned by the rapid development of academic circles? Or is it that I am too weak and vulnerable to Zhou Congwen.

Zhang You looked around in a daze. He was good at observing, especially in the hearts of the people.

From the facial expressions of other people, Zhang You can see that not only he has this idea, but others also think so.

Questioning is an instinct that must be found in the academic community.

But even hundreds of professional doctors listened to Zhou Congwen with doubts at the same time, they still couldn't find out the problem.

No one even asked a question.

Zhou Congwen's speech was already meticulous enough. If you change to a medical student with some common sense in medicine, you can understand it as long as your mind is not very sharp.

Simple and clear confusing.

"The fourth point - the first time you get the guide wire into the branch is to pay attention to something when entering from the proximal mesh.

The edge-branch guide wire is improvised in the body, so that its end forms a "U loop" and is sent into the deep part of the main branch blood vessel. Then, the guide wire is retracted to 1/3 of the upper part of the edge-branch stent opening, where wire is wired and ensure that the guide wire is located in the edge-branch stent cavity."

"Here, U loop is very important. Maybe everyone didn't notice this when watching the operation. Now let's watch the operation recording."

"Here, the person who recorded the surgery missed the process of shaping my body. The U loop is at this angle. After entering the patient's blood vessels, it will follow..."

U loop, a ray of thunder fell on Zhang You's head.

What are technical details!

This is the technical details!!

The people who recorded the operation did not observe it, nor did they appear in the video. Everyone thought that Zhou Congwen was a little distracted at the time and was fiddling with the guide wire casually.

But who would have thought that there was another unexpected technical detail here?

If you think you understand the operation, you will go back like this and watch it repeatedly and then take the operation, you will inevitably get stuck at this step.

U loop, who would notice this?

The guide wire at 18 was deformed a little bit, and if it weren't for pausing or enlarging, no one would have seen it.

The air in the Great Hall became more and more weird.

Deng Ming sat next to Mr. Huang holding the thermos, and he felt ashamed.

"Boss, I didn't see this U loop."

"Zhou Congwen is good." Old Huang said in a low voice, "When I first performed, I didn't remind him, he did this action. Deng Ming, you have done less interventional surgery."

"..." Deng Ming held the thermos and looked helplessly at Zhou Congwen standing on the stage with a full-minded spirit.

It’s not that he is full of energy. Zhou Congwen doesn’t care about this, and he also knows that the boss doesn’t care.

Instill all the technical details into the circulation doctors here, no matter whether he is from 912 or from domestic or foreign, he learned to go back and have surgery immediately.

The boss thinks so, and Zhou Congwen thinks so too.

Alas, he was really a natural master and apprentice, and Deng Ming began to be a little envious.

In front of Zhou Congwen, he and the boss seemed to be strangers, and Deng Ming felt a little awkward.

"This is very important, and I can't explain it more carefully, because it involves hemodynamics." Zhou Congwen finished explaining and smiled slightly, "It needs to be summarized repeatedly in practice. After all, everyone has different surgical habits, and the angle of the U loop will be slightly different. What I am talking about here is a general meaning."

"Next, let's talk about the fifth point - the first balloon kiss."

"The balloon is expanded by the side support stent that is retracted to the bifurcation and feeds the guidewire that reenters the side support stent into the side support stent.

Retreat the embedded balloon at the distal end of the main branch vessel, so that its proximal mark reaches the proximal end of the side branch stent and is flush with the side branch balloon, and then perform the first balloon kissing."

"Notice!"

Zhou Congwen increased his voice, and his voice echoed in the conference hall like an echo in the empty valley.

Some doctors are still immersed in the previous technical details and are unable to extricate themselves.

They were woken up by Zhou Congwen.

"The details here are that the two balloons are flush and aligned with the bifurcation of the blood vessels, which is equivalent to the multilateral area of ​​the bifurcation of the blood vessels. The sequential high-pressure dilation is first, and there is a decompression gap during the period, and then the sequential dilation is performed."

"There are a few points to pay attention to when choosing the pressure relief gap, first..."

“The sixth point – the main support is placed in the bracket.

After completing the first balloon kiss, withdraw other instruments, retain only the main support guidewire, send it into the main support stent and expand and release it, withdraw the side support balloon, and retain the main support guidewire.

Another withdrawn guidewire is also rewireed to the edge branch with the "U loop" technique, that is, the second time the guidewire is lowered to the branch."

“…”

"At the seventh point, the final balloon kiss: two non-compliant balloons were sent along the two guidewires.

Because non-compliance balloons were used during the first kiss, they need to be plasticized again and finally kissed.

If a close friend encounters difficulties in passing the edge branch of the compliant balloon, do not force it to avoid damaging the stent.

At this time, you can choose to pre-difference the main support stent mesh in the small balloon, and then try to use the non-compliant balloon to pass the edge. Finally, when the balloon kisses, the order of high-pressure dilation is also performed first, and then the order of kisses is expanded sequentially."

“…”

“Fifteenth point.”

“…”

“Twenty-one.”

As Zhou Congwen tells more and more details, the doctors in the audience all showed a dazed look.

Not everyone has the memory of the slogan.

If someone else gives a lecture, the doctors in the audience can prove each other based on their clinical experience, and just listen to it.

After all, no matter who teaches, there is countless moisture.

But Zhou Congwen is not. He told everyone what he did, as if he was afraid that he would not be full.

Can……

Almost all the doctors almost choked to death.

It's too dry, it's all the essence, but who can remember so much in just a few dozen minutes, and remember it without saying a word?
