With the microcatheter in place with incredible speed and posture, Step 2 of the surgery was successfully completed.

"Did you see where Dr. Yun placed the microcatheter?

The placement of the microcatheter is very pleasing to the eye.

Because next, Yuntian needs to seal the arterial leakage under the condition of controlling the taste hall.

The difficulty of sealing an arterial leak is actually very large.

This is especially important when it comes to the need for a successful operation.

After all, none of the intracranial blood vessels are useless.

Each blood vessel dutifully supplies its own blood supply to its own area.

Brain tissue, on the other hand, is sensitive to ischemia and hypoxia.

Affecting the blood supply to any artery causes acute avascular necrosis of the brain tissue in that area.

It then causes severe sequelae of stroke.

In severe cases, life may even be lost.

The fistula of an arteriovenous fistula is only connected to a normal blood vessel!

When performing arteriovenous fistula embolization, it is necessary not only to completely close the arteriovenous fistula, but also to ensure that normal blood vessels are not affected.

The occlusion material selected for arteriovenous fistula is often gelatinous.

Although the gelatinous material works better for the demeanor.

However, it invisibly increased the difficulty of surgery again.

Whether we glue into the water pipe or other containers, the controllability of the gel will always be affected by various reasons.

Therefore, the completion of arteriovenous fistula embolization is lower than that of ordinary surgery.

But at this time, the position where the microcatheter is placed in Yuntian makes people feel very comfortable.

A microcatheter that is parked right at the arteriovenous fistula.

Slightly probed into the intersection of the meridians by about a millimeter.

This is the best place to dispense.

The microcatheter is inserted into the artery that leaks a little inside.

It leaves a certain amount of room for the injection of glue, which is not easy to affect the normal blood vessels.

It will not cause various cerebrovascular embolism accidents caused by the blockage of normal blood vessels.

The degree of entry is only about one millimeter, and such a slight distance will not affect the effect of arteriovenous fistula blood vessel embolism.

Therefore, seeing the location of Yuntian's microcatheter, Director Zeng and Fei Qiang were holding their mouths at the same time.

Just looking at the location where Yuntian was parked made the two of them extremely comfortable.

"Just about one millimeter, which is exactly in line with the requirements of the surgical guide!" I found that Dr. Yun did such a pleasing operation every time, and the biggest problem was that he could accurately control every step and complete 100% of the procedures according to the requirements of the surgical guide!"

"This is simply unacceptable!" Fei Qiang entered the neurology department of 913 Hospital at such a young age, and his talent is not something that ordinary people can have.

After watching Yuntian's half-time surgery, Fei Xiang discovered the key node where Yuntian's surgery was done so smoothly.

"Of course I know the standard of his surgery because every step is standard, and you know it now, but can you do it? If you can't do it, even if you know Dr. Yun's secret, it won't work!" Director Zeng replied with a very proud look.

"Hehe, hehe, isn't this just trying to find the reason for Dr. Yun's smooth operation!" Fei Qiang laughed embarrassedly.

I naturally knew that I couldn't be like Yuntian, and every step was completed 100% in accordance with the surgical guidelines.

However, it is also a joy to be able to find the secret of Yuntian's surgery.

Fei Qiang, who was hit by Director Zeng, was not angry at all.

On the contrary, I was secretly happy.

Although I couldn't do the surgery so pleasing to the eye like Dr. Yun, I finally found the direction of my efforts.

If you have a direction and want to make progress, you must at least have a direction to work towards.

After the microcatheter was in place, Yuntian rinsed the microcatheter with 0.25Ml dimethyl subfeng.

After that, preparations were made for the injection embolization of the arteriovenous fistula with ONYX-18.

"Director Zeng, don't you think that Dr. Yun is much more handsome than us even when he washes a microcatheter?" Fei Qiang was hit by Director Zeng, but he was obviously not discouraged, and it seemed that he was ready to make persistent efforts.

"Of course, Dr. Yun's work of washing a catheter is also carried out in strict accordance with the requirements of the guidelines, and the time and speed of injecting drugs are exactly the same as those in the book! To be honest, I also admire him!"

"You are a doctor at the director level of a dignified imperial capital tertiary hospital, how can you be soft in front of an intern?" Looking at Director Zeng's expression of emotion, Fei Qiang seized the opportunity to prepare to scold Director Zeng.

A gentleman takes revenge, but he has to take revenge on the spot!

The relationship between the two is obviously good.

Director Zeng listened to Fei Qiang's words and reached out to give Fei Qiang a violent chest!

The two of them flashed their heads, and Yuntian had completed the embolization of the first blood supply vessel of the arteriovenous fistula.

"It's a pity, it's a pity, I didn't see the process of Dr. Yun's glue assistance!" Director Zeng looked back at Yun Tian, who was withdrawing the microcatheter, and said with emotion.

"It's okay, I watched the whole brain angiography done by Dr. Yun before, according to my judgment, Dr. Yun has to embolize at least two arteriovenous blood supply vessels, I want to see that there is still a chance!" said that he saw for himself, Yun Tian completed the whole brain angiography operation, and Fei Qiang couldn't help but raise his chin and began to be proud.

"There are still two embolizations, does the patient actually have three blood supply vessels this time?" Director Zeng asked in surprise.

Generally, arteriovenous fistulas only have two blood supply vessels at most, but when they arrived in Yuntian Town, they actually became three.

This is no joke, 1+1=2.

By adding a blood supply vessel, the difficulty of the operation is increased several times.

The operation to embolize three blood vessels is obviously much more difficult than the operation of two blood vessels.

Patients also have a much higher chance of complications.

"This Doctor Yun is an arteriovenous fistula embolization operation for three blood supply vessels, this is to be reported to the department!" As soon as he heard that there were a total of three blood supply vessels, Director Zeng became anxious.

Arteriovenous fistulas of three blood vessels need to be reported to the senior doctor according to the requirements.

Yuntian started the operation without saying a word, obviously not communicating with any doctor.

"This kid...!" Director Zeng still had some opinions about Yuntian's behavior.

But now that he is cooperating with Yuntian in a scientific research project, he still has to rely on him to do surgery.

What's more, Yuntian's surgical level is now more than half of his own!

Even if you report to yourself, your level is not as good as Dr. Yun, what is there to report?

Although Director Zeng, who has figured it out, is still a little lost, his mental state is much better.
