The micro-guidewire on the screen slid slightly, gliding through the narrow place as if it had an eye.

In the eyes of ordinary people, there is no other trick except that it seems to be lightweight and too smooth.

But the people sitting here are all interventional doctors in neurology!

He is also the best neurointerventional doctor in all regions of the country!

Under such a light action, it requires a deep foundation to rely on!

Therefore, watching the micro-guidewire on the screen gently slide over the narrow place, there is a "hiss" gasp sound in all directions.

"Glide perfectly!"

"yes, no plaques at all!"

"It takes a steady hand to do that!"

"It's not just stability, it's also important to have eyesight and judgment!"

Before everyone could finish it, Yuntian had already begun to expand the balloon.

"Do you think the balloon is getting too big?"

Someone asked aloud after at least a minute.

"I don't think I feel any change in the balloon!"

Someone replied in surprise.

"What is this for? Is the dilation too slow or not moving at all?" More people are puzzled, if they were thinking about the surgical plan after the imaging before, now it is just a balloon expansion, it seems that there is no need to think about it for so long, right?

"In the morning, when Dr. Yun explained, he said that it takes at least two minutes to expand the balloon, and it is best to expand at a uniform speed, so it should be slow and uniform in the speed ratio, so I can't feel it!" someone speculated.

"Look, I shot it a minute ago, and this is now, and it's obviously changed!"

Some of the more serious people actually took pictures when the small balloon began to expand, and began to compare them.

"Yes, the small balloon has expanded by about a third!" many people watched curiously. As soon as the two photos are compared, the results are obvious.

The gasp of "hiss" resounded throughout the audience again!

It is not difficult to expand one-third of the balloon in one minute, but the difficult thing is that in this minute, everyone has not felt any change in the balloon, which is enough to prove that the speed of the small balloon expansion in the previous minute is absolutely uniform and stable.

Only a uniform and stable expansion speed can be imperceptible.

Unlike the previous micro-guidewire, which can pass through the spot sound area quickly and smoothly, it is more difficult to have a uniform and stable speed at this time, which requires continuous and stable force in the hand, and the stability requirements of the hand are much higher.

All of you here are interventional doctors, and a pair of hands that can continue to exert force and maintain stability are naturally a dream!

It's so stable!

It's a hand-made for interventional doctors!

What's more, these hands are extremely slender, and they can be easily recognized even when they are wearing hands

More than 200 people in the venue felt envy and even jealousy almost at the same time!

At this time, Director Yan just finished brushing his hands and appeared in the cāo) room.

Seeing that Yuntian cāo) made a micro guidewire smoothly slid through the plaque, and then saw the steady expansion of the small balloon, Director Yan was stunned!

Can this be done by an intern who has only been exposed to interventional surgery for three months?

So smooth,

So smoothly,

So stable!

Director Yan, who was dressed up, was stunned to the side, and for a while he was also shown off by Yuntian's cāo) work!

The balloon continued to expand, reaching about half the diameter of the basilar artery before slowly stopping.

Yun Tian carefully observed the blood supply near the small balloon and the small blood vessel branches under the plaque.

Then comes the most important step.

Place the stent.

If there is only a small vascular branch under the plaque, when the stent is inserted, just pay attention to the degree to which the plaque at the small vascular branch is propped up by the balloon, and the two hands should cooperate well when opening the stent.

Now, however, patients are at high risk of hyperperfusion.

If the stent is opened quickly, the patient will inevitably have hyperperfusion, which may cause brain swelling or hemorrhage at any time, which can kill people in minutes.

Therefore, Yun Tian closed his eyes and stabilized his mind a little.

"Doctor Yun, do you need help?" Although Director Yan was shown off by Yun Tian wearing a micro guide wire and an expansion balloon before.

But at this time, seeing that Yun Tian soothed his mind, he immediately thought of the purpose of his coming in, so he asked softly.
