The operation was already going on before Lu Cheng arrived, so the preliminary preparations for the thrombus removal operation had been made, and all that was left was to wait for Lu Cheng to come on stage.

However, it seems that for Lu Cheng's convenience, the circulating nurse prescribed a new F2 Forgaty catheter!

Lu Cheng and Yin Yu washed their hands and came on stage almost at the same time. Yin Yu stood opposite the chief surgeon's position very neatly. Before that, Yin Yu stood where Lu Cheng was standing now, and Yin Yu was not the first

The person standing in this position was someone from the department who called him over first after encountering an emergency operation and was really unsure.

Lu Cheng was the third person to be called to the position of surgeon.

After Lu Cheng took over the F2 catheter, he took a general look at the patient's current situation. Except for the particularly terminal branches like the superior and inferior ulnar arteries, more than half of the blood vessels in the proximal segments of the ulnar artery and radial artery contained thrombus.

It has been solved!

However, thrombi in the more distal parts of these two arteries still remain.

In addition, the thrombus in the ulnar recurrent artery, radial recurrent artery, and anterior and posterior interosseous arteries did not move at all.

The anterior and posterior interosseous arteries are branches of the common interosseous artery. The common interosseous artery originates from the ulnar artery and is a fourth-level branch, which is particularly troublesome to deal with.

Both the ulnar artery and the radial artery are directly branched from the brachial artery, so you can still rely on experience. If you want to go inside to remove the thrombus from a smaller branch without angiography or interventional monitoring, then of course you can.

It is quite troublesome. And this does not include the thrombus in the more distal deep and superficial palmar arches, and even the more distant intrinsic arteries on the palmar side of the fingers.

Seeing this situation, Lu Cheng took a deep breath through the mask, then looked at the newly opened arterial catheter, took it in his hand, and began to rotate it.

Lu Cheng could see the shape of the distal end of the Forgaty catheter through his glasses, so he quickly reached the bifurcation of the brachial artery and the ulnar artery. Lu Cheng thought about it and decided to start with the direct shape of the ulnar artery.

Start picking up at.

With a slight rotation, the tip extended into the lumen of the ulnar artery, and then bypassed the bifurcation of the common interosseous artery and the bifurcation of the ulnar recurrent artery.

It is a pity that this operation does not have interventional monitoring. Otherwise, Yin Yu and the others would be able to see Lu Cheng's wonderful operation, and now they can only stare at Lu Cheng's hands!

Everyone is mortal and cannot see the specific situation inside. We can only feel the final effect of the operation after Lu Cheng pulls the blood clot out.

Lu Cheng didn't let them wait long. He continued to exert force intermittently, and soon he continued to penetrate deep to the position close to the pronator quadratus muscle. Then Lu Cheng used a syringe to bring physiological saline, flushed the distal end of the catheter, and then began to insert it rhythmically.

Pull back.

At this time, Lu Cheng can actually go deeper, but this is not the first time Lu Cheng has taken out a thrombus. He knows that if too many thrombus are taken out at one time, it may cause accumulation and put too much pressure on the lumen of the blood vessel.

When a bifurcation occurs, it is easily squeezed into other bifurcations, making the operation more difficult.

Therefore, Lu Cheng just took the easiest position to operate and started to fiddle with the catheter back.

Of course people like Yin Yu from the vascular surgery department knew what Lu Cheng's pulling back movement meant, but how could Lu Cheng be so sure that he had reached further away from the thrombus? What did he rely on to be sure?

Yin Yu asked doubtfully: "Xiao Lu, do you feel it?"

"Yeah! Almost!" Although Lu Cheng saw that he had pulled the blood clot back, he didn't say it too harshly.

Yin Yu did not disturb Lu Cheng and continued to watch.

About half a minute later, Lu Cheng pulled out a long strip. This length was similar to the thrombus strips they had seen in the video before, but the size was because the diameter of blood vessels in the upper limbs was smaller than that of the blood vessels in the lower limbs.

So it's more detailed.

Seeing the thrombus strip coming out, all the onlookers looked at each other in shock.

Among these people, there were some who were vascular surgeons and some who were not vascular surgeons, but that didn't stop them from being shocked at this moment. Because Yin Yu had done it before, but he had only worked for free several times, but Lu Cheng came up

, just got the thing out directly, this is the gap!

Lu Cheng did not stop, but continued to walk the same way and returned to the farther end of the ulnar artery, probably at the position where the shallow arch of the palm straddles, stopped again and went deeper, and then continued to pull back, once again removing the thrombus.

came out.

This finally made Yin Yu unable to stand still. She stopped pretending that she could understand and said, "Xiao Lu, where did the blood clot you just removed come from?"

You know, it may be luck to take it out the first time, but it is definitely not luck to take it out twice in a row. And if you don't ask now, then when will you wait?

If you still care about the director's face and the professional's face at this time, then just don't ask Lu Cheng to come on stage in the first place.

"Oh, it's probably the section from the palmar arch of the ulnar artery to the pronator quadratus muscle. My idea is to remove the thrombus in the main branch of the radial and ulnar artery first, and then remove the smaller branch arteries.

Lu Cheng replied calmly, and then put the catheter in again without any trouble, like a tireless soldier.

It's okay not to listen. As soon as he heard this, Yin Yu and the people around him fell silent again.

Where did this fucking pervert come from? Even if you can remove the blood clot, you can also tell the approximate location. How many fucking people have you dissected? You can determine the approximate location just by doing it blindly.

Really? How about just being a human being?

When performing blind operations, there is no subjective vision and no positioning point. This is the difficulty of operation.

It is also a difficulty in embolectomy after emergency trauma. At this time, most patients have arterial embolism, so neither contrast nor contrast media can be used, and leakage of contrast media is not a joke.

Lu Cheng went deep again and pulled back the thrombus at the more proximal end of the superficial palmar branch of the radial artery little by little.

However, in the middle of pulling back this time, when passing through the bifurcation of the ulnar and radial arteries, something happened. One end of the thrombus actually penetrated in the direction of the ulnar artery. This is what happens during thrombectomy.

Accident.

But at this time, Lu Cheng didn't panic at all. He used the Forgaty catheter that Yin Yu and the others had used before, and used it to block the end of the ulnar artery. After it was filled, there was no need to worry about blood clots running around.

"What's wrong? Do you need help?" Yin Yu saw that Lu Cheng used an extra catheter and thought there was an accident during the operation.

Lu Chengcheng said: "The thrombus is displaced. I blocked the branch opening of the ulnar artery. Teacher Yin, can you help me fix the syringe?"

What's wrong with this?

However, while taking the syringe, Yin Yu seemed to understand what Lu Cheng said, that is, Lu Cheng probably blocked the branch opening of the radial and ulnar artery to prevent the thrombus from migrating toward the radial artery.

No, how do you make sure that the newly inserted catheter reaches the branch opening of the ulnar artery and blocks the opening of the radial artery?

Is it open?

Open is a term in the game.

Yin Yu was a StarCraft player a long time ago. Later, his hand speed couldn't keep up, so he switched to Dotaer. Although he doesn't play much now, firstly, he is too old, and secondly, his hand speed can no longer keep up.

I'm thinking about it, but I also occasionally watch live broadcasts and games. So I also get to know some new games and terms.

Open means cheating. In CS and chicken games, it means that there is a perspective cheat, so you can't see things that you can't see under normal circumstances.

Otherwise, other than this, Yin Yu would never have thought of what Lu Cheng used to determine it.

Could it be that Lu Cheng is not a human being, so he can see things that normal people cannot see?

This question cannot be asked directly.

Lu Cheng didn't care how Yin Yu and the others felt, and quickly pulled out the thrombus. It was still about the same length. Although it looked a little dark and fat, it looked extremely cute at the moment. Because every time one more blood clot was taken out, the patient's

The possibility of saving your hand is even greater!

After taking it out, Lu Cheng continued: "Teacher Yin, please don't move for now. I'll take out the rest of the shallow arch of the palm again, and I'll go through the radial artery! To avoid any further accidents."

Yin Yu was numb, so she nodded.

I have basically determined this in my heart, that is, Lu Cheng, you are invincible, so you can do whatever you want.

I don’t even want to discuss anatomy and other principles with you. You are anti-human! If you go back a few decades, you will definitely be hung up as a freak.

Can surgery still be done like you did?

If I could know where the distal end of my catheter is now and take it wherever I want, I could do a better job than you, Lu Cheng, but what I can’t do is how to determine the catheter position. So you are invincible, so you

random!

While Lu Cheng was removing the thrombus, he could still hear whispers: "How is this positioned?"

"I don't know, how does it feel? I've never heard of it."

"I haven't heard of it, and I don't understand it. If I understand it, then everything will be simple."

"This is really amazing. It can be positioned with just a catheter. No wonder Professor Yin called the other party to solve the problem. This is probably a very famous teacher."

"You are a cruel person, learn from it."

"But how to learn? Before you have this feel, no matter how much you learn, it's useless. You can only rely on practice for the feel."

"Then just watch quietly!"

Lu Cheng actually wanted to say, in fact, you have all misunderstood. I just drove it and asked me to determine the position by feeling. In fact, I can't do such a difficult operation, but I can't say it.

Lu Cheng had no expression on his face, pretending not to know anything, and then continued to remove the thrombus in the anterior interosseous artery and posterior interosseous artery, which were more difficult than the ulnar artery and radial artery, divided them into three sections, and removed them six times.

!

Every time, after the blood clot was removed and the location was explained, everyone looked expressionless and no longer felt strange.

If they didn't know that their lack of expression was due to numbness, everyone might think this was a basic operation.

In this way, Lu Cheng's last incident of removing the dorsalis pedis artery thrombosis was basically confirmed by everyone, and the last incident of the patient's amputation due to a change of surgeons was finally determined by these colleagues, that is, he deserved it.

In fact, at first, they felt wronged for Lu Cheng mainly because of the difficulty of the surgery itself.

Since the famous Professor Snow couldn't do anything, even if the young man couldn't take it out, it was still a limitation of medical level. The current ceiling of surgery is here.

So even if he is powerless, it cannot be said that he is guilty?

But now, it’s completely different. Lu Cheng actually has this ability, while others have been working hard. It’s just that Xu Shixiong’s family members think that foreign professors can do surgeries better than Lu Cheng. According to common sense, everyone will go in that direction.

Common sense was taken away from me, which led to such a tragic accident.
