Zheng Ren didn't say anything, just changed his clothes in silence.

"Let's go, go see what's going on. Director Kong also hurried to change his clothes, put on a sterile cap, and walked in quickly.

Coming to the operating table first, Director Kong began to review the images of the surgical process.

During the stent removal process, the angle is slightly off, touching the liver parenchyma, causing a small arteriole to rupture and bleed.

This is also the reason why in the previous TIPS surgery only had a stent and was never recovered.

The second retrievable stent is placed and the patient is used to the ammonia condition before being removed to expand the outflow tract. But the process of removing the second retrievable holder has many difficult points.

Zheng Ren dared to do this because the interventional surgery skill tree had reached the level of a master. But before he could teach Zhu Liangchen a lot of details, he tried to do it himself.

This is the ......

In fact, it can't be said that Zhu Liangchen is completely wrong.

It's just that this kind of mistake is completely unnecessary.

He stood behind Director Kong, looking at the image of Zhu Liangchen's surgery, but he came to the system space and clicked on surgical training.

The system operating room rose from the ground, and Zheng Ren did not hesitate to enter.

His heart was dripping blood.

Although there is still plenty of time to spare for surgical training, this is completely unnecessary "consumption". Zhu Liangchen!

Zheng Ren thought with hatred in his heart.

His heart was already dripping blood, and he didn't waste time on surgical training and started the operation directly.

In fact, with Zheng Ren's level of interventional surgery, he can go directly to the stage. But this is an accident after all, taking over Zhu Liangchen's surgery by himself and doing it by himself are two different concepts.

Zheng Ren still chose to buy surgical training time safely, and if there was any problem, it was better to let the experimental subjects bear it in the system operating room.

Zheng Ren has long studied this complication. Embolization is undoubtedly the best option.

He first deflated the stent a little, and immediately saw that there was blood flow.

The puncture work has been done by Zhu Liangchen, and Zheng Ren began to overselect the artery.

Patients with advanced cirrhosis have atrophy of the liver, and the arteries have anatomical abnormalities due to various reasons. In addition, the spleen is enlarged and the coagulation mechanism is not good, so one or two hours of compression with a membrane stent to stop bleeding has no effect.

The imaging results showed that the bleeding arteriole was an artery bordering the fourth and fifth grades. It's very fine, and the difficulty of overselection is not ordinarily large.

However, for Zheng Ren, the difficulty of this kind of overselection will not be more difficult than prostate interventional embolization.

The left and right hands are crossed, and Zheng Renchao is very skilled and meticulous.

Because patients with advanced liver cirrhosis have poor liver function and liver atrophy, they can have less embolism and less embolism, so as not to lead to liver failure.

The guidewire enters, layer by layer, and finally comes to the bleeding artery.

It was almost an embolization of the bleeding point, and Zheng Ren was sure that even if his interventional surgery level reached the peak level, he could only do this step.

There is nothing special about the surgery, it is to test the technique of overselection.

Embolization, re-imaging.

Zheng Ren was very sure, but the system only gave 85% of the completion of the operation.

Strange, why is this the case?

After observing for a few minutes, Zheng Ren found that except for a small artery, blood was constantly oozing from the passage where the stent was placed.

This is the result of repeated rubbing, which results in extensive contusion of the liver parenchyma.

Zheng Ren was also helpless.

Zhu Liangchen's technique was wrong, which caused greater damage to the side of the operation.

What should I do? Zheng Ren was also a little helpless for a while. Embolizing arterioles can solve a big problem. The patient just stepped down, but it was fine. The problem of bleeding may get better quickly, but it is also possible that it will continue to bleed, leading to worsening of the condition and eventually hemorrhagic shock.

We can't wait for the patient to heal on their own, we have to solve this problem! Zheng Ren immediately made his own choice.

If you try your luck, don't do it. Although Zheng Ren has a lucky bonus, he is very disgusted with this in his heart.

Then over-select, find several supply arteries at the site of the contusion of oozing blood, over-select, embolize.

Zheng Ren faced a problem, the more meticulous the overselection, the smaller the range that can stop bleeding. In this case, more overselection and embolization will be done.

How to achieve a point of maximum gain and minimum damage is difficult.

But fortunately, there was a lot of time for surgical training, so Zheng Ren simply tried it little by little and did it little by little.

Thankfully, this is a system operating room where mistakes can be made.

As time passed, Zheng Ren gradually figured out a balance. Embolization of grade 3 or 4 arterioles can avoid greater damage to the patient, but can successfully stop the bleeding.

It's just that the time spent on surgical training is wasted, which makes Zheng Ren feel a little distressed.

Fifteen hours later, Jeong-in finally saw that the surgery was 97% complete.

That's it, no matter how much, it is estimated that it will be difficult to achieve.

After all, the patient's platelets are more than half of the normal person's, and in this case, the completion of 97% of the operation has almost reached the limit.

He glanced at the subject, with some regret.

Turned around and walked out of the system operating room, back to reality.

Director Kong finished reading the operation process and said in a deep voice: "Old Five, I and Boss Zheng, you rest." ”

Zheng Ren hurriedly went to brush his hands.

When he went on stage with Director Kong, he couldn't wait for the professor to finish his preparations and then go on his own like Professor Rudolf Wagner.

To the old director, I still have to show respect.

Seeing Zheng Ren running to brush his hands and prepare, Director Kong glanced at Zhu Liangchen deeply and shook his head slightly.

Zhu Liangchen felt dry and a little embarrassed, but he was a little dissatisfied with Zheng Ren's arrival.

All kinds of complicated emotions were intertwined, and he lowered his head and didn't look at Director Kong.

Director Kong is nothing, brushing his hands and going on stage.

"Boss Zheng, you do it. After Director Kong went up, he stood directly under Zheng Ren and squeezed him into the surgeon's position.

Zheng Ren did not continue to be polite, directly plugged the microguidewire into it, and began to perform super-selective arteriography + arterial embolization.

In the operation room, Zhu Liangchen looked at the old and the young on the operating table through the lead-made glass in a daze.

Did he do something wrong? He didn't think so.

It must be a problem with the design of the surgery, and there should never have been two stents with membranes in the first place!

The second-stage surgery is very difficult and completely violates the guidelines for TIPS surgery for so many years.

Zhu Liangchen tried for a long time, but he didn't operate too violently. They are all old doctors, and they are all people who have undergone hundreds of TIPS surgeries, and they all know in their hearts that violence will definitely not solve the problem.

It may be possible to violently remove the stent with membrane, but it will definitely be accompanied by massive bleeding. It wasn't until the end that Zhu Liangchen reluctantly called Director Kong and asked for help.

Can he stop the bleeding successfully, Zhu Liangchen began to look forward to it in his heart.

As for the future, TIPS surgery, or don't touch it. Even if it's modified, it's too risky.
