God appreciates people who eat and eat, and others can't envy them!

This was the thinking of most people in the room at this time.

With the emotion and various thoughts of everyone in the venue, the micro-guidewire on the screen has stopped steadily at the vertebral artery.

This time, Leng Chengye finally did what a qualified and excellent assistant should do.

Open the pressurized injector in time and inject the contrast medium.

Two lesions are clearly visible under the branch vessels of the vertebral artery.

As close as possible to the blood vessels supplying the tumor, chemotherapy drugs are injected, and the treatment of a lesion is completed.

Although Yuntian is able to puncture the needle, the travel speed of the micro-guidewire in the large blood vessels is also very fast.

But this can only mean that Yuntian's basic skills are very solid.

And the real test of technology is what level of blood vessels can be overselected now.

The smaller the blood vessels, the closer to the tumor focus, the better the drug delivery effect, and the fewer side effects.

Naturally, it is also more able to reflect the skill level of the surgeon.

Although the clouds did a good job before.

But at this point, everyone's eyes widened to see how far Yun Tian could go.

Director Meng clenched his fists tightly.

Liu Guanghui looked serious, and the gentle smile that had been on his lips seemed to disappear

Lou Xue was really a little nervous, after all, Yuntian's technique of pushing micro guidewires in the blood vessels just now, he just closed his eyes and simulated it a little, and he could feel that he could not do it to that extent, but it was also very reluctant!

Lou Xuezhen had to admit that in the direction of basic skills, Yuntian surpassed his own level.

What about super-selection?

How far can this cloudy sky go?

Lou Xuezhen had a faint feeling that this Yuntian might do something that would continue to surprise everyone.

The entire venue was silent, the pins could be heard, and everyone was waiting quietly with their eyes wide open and waiting for the next move with Yuntian.

It took at least 5 minutes for the microwires on the screen to start moving slowly.

From the vertebral artery to the basilar artery, the travel speed of the micro-guidewire is very slow, but very stable, as the travel speed of the micro-guidewire slows down, there is finally no impact of the micro-guidewire rushing forward in the large blood vessels before.

The microwires move slowly in the intracranial blood vessels, and they move steadily towards the target blood vessels of the tumor.

Everyone stared nervously at the movement of the micro-guidewire on the screen, at least so far, Wei Nan's speed had been steady, and his work was very steady.

Gradually, the microwires have reached the tertiary branch of the cerebrovascular tree, and when they reach this position, the interventional chemotherapy for the lesion of the injection of chemotherapy drugs is completed!

This intern, who has only been exposed to interventional surgery for three months, is really capable of completing interventional chemotherapy for second-level intracranial tumors!

Everyone has sighs in their hearts!

You can get the second-level interventional surgery in three months!

It's still an extremely complex secondary surgery!

There are really demonic characters in this world!

But after everyone sighed in their hearts, they found that on the screen, the microguidewire after the memory reached the tertiary branch of the cerebrovascular tree was still there

Moving forward slowly, there is no intention of stopping.

Further on are the branches of the blood vessels that supply blood to the tumor.

What is this guy going to do?

Addicted to over-selected blood vessels?

Can't stop at all?

Nearly 500 people in the entire conference room watched in amazement as the microguidewire entered the tertiary branching of the tumor's small blood supply blood vessels, and then finally stopped!

What is this for?

The lad is too nervous?

So over-selection?

This was the idea that arose in the hearts of the five hundred people in the hall at the same time.

After all, this location has almost entered the tumor, and this position belongs to the branch of the blood vessel supplying the tumor, and if the chemotherapy drug is injected from this position, there is no way to cover the entire tumor!

So, the guy should be too nervous, or too eager to show his skills, and accidentally overshoot!

This is the only explanation that everyone can think of!

However, at this time, the microwire quietly stopped at the branch of the blood vessel supplying the tumor, and there was no intention of retreating.

Instead, start withdrawing the microwire, pull back, no blood clots, and connect a new pressurized injector!

This is!

Is it really not going to fall back into a reasonable vessel?

Is the young man going to make the wrong mistake and only do this branch,

Is chemotherapy drugs injected into only half of the tumor?

But if this is the case, it will not achieve the required treatment effect at all.

"Director Shi, are your students only going to inject medicine into half of the tumors now in order to show off their super-selection skills?

"In order to show his skills at the annual meeting, he didn't even care about the treatment effect, he is really a good doctor!" Director Meng seemed to forget the pain of being slapped in the face before, and turned on the mockery mode again!

On the screen, as everyone expected, after retracting the blood-free coagulation pleasure and reconnecting the new pressurized injector, Yuntian began to inject chemotherapy drugs into the tumor vascular branches.

Suddenly, there was a buzz in the conference room:

"Injecting medicine into this blood vessel can only work on half of the tumor, and it can't achieve the treatment effect at all.

"Hehe, what a fairy cāo) does, this is the time to fully show his surgical level, no matter what treatment effect he has!"

"Isn't this a bit excessive? Although it is a demonstration operation, the patients are all living beings! Half of the medicine is given, and the other half grows faster, this kind of treatment is completely meaningless!"

"The current Nian Shi people are so happy, they really care about human life!"

In the conference room, where the pins could be heard, all kinds of discussions spread in an instant.

There are also many people who even start pointing fingers at Director Shi.

Director Meng looked at Director Shi and felt very proud that Director Shi didn't fight back against his ridicule!

As chemotherapy drugs were slowly injected, something even more surprising happened.

The surgeon actually began to inject gel sponges!

Infused with a gel sponge?

Vascular embolism?

It's an intracranial blood vessel!

If something goes wrong and affects the blood supply to normal brain tissue, it will cause various neurological disorders such as hemiplegia and paraplegia!

If the blood supply to a critical area is blocked, it may even cause immediate death for the patient!

This is why interventional chemotherapy for intracranial tumors is only a second-level interventional surgery in neurology, while interventional embolization for intracranial tumors is the fourth-level surgery with the highest level in neurology!

Two techniques, the difference between the two words, but very different!

One is a second-level surgery of average difficulty, and the other is a fourth-level surgery with the highest level of neurology!

How dare he change the technique directly in the hands of the demonstrator!

A surgical change requires a lot of procedures, at least with the consent of the patient's family.

After all, embolizing any blood vessel may lead to the blockage of the patient's normal brain tissue blood supply!

Serious consequences!

But right now, at the annual meeting of the Department of Neurology, someone actually changed the operation directly!

Since the start of the operation, because it is a live broadcast, everyone can see clearly, the surgeon and the assistant have never left the operating table, and they have not discussed it with the patient's family at all!

To put it seriously, this can even be regarded as medical malpractice!
