Yun Tian, who was immersed in the operation in the cāo) studio, was completely unaware that his hand had been looked at by more than 200 people in the conference room, and he was in danger of being stolen at any time.

At this time, the clouds have reached the vertebral artery as a microwire.

"Contrast agents. Yun Tian whispered.

After speaking, Yun Tiancai realized that Leng Chengye was pressing next door to stop the bleeding, and now he was the only one in the room.

If you want to inject contrast media, you have to open the pressurized injector yourself.

Sure enough, it is easy to go from simplicity to luxury, and it is difficult to enter simplicity from luxury.

After cooperating in the past few days, Leng Chengye has gradually grown into an excellent assistant, and Yuntian has become completely accustomed to the feeling that Leng Chengye can concentrate on the operation by the side.

Just now, in order to catch up with the progress of the operation and prevent this operation from being snatched away by the person before just now, Yuntian did not wait for Leng Chengye to finish pressing to stop the bleeding before starting.

So much so that at this time, there was only one person in the cloudy sky.

Interventional surgery is different from other surgeries, with a number of helpers such as one assistant, two assistants, instrument nurses, and itinerant nurses.

Even, if the chief knife has a good heart, he can also call a large group of students to watch and shout 666 on the side.

Interventional surgery is performed under X-rays and is performed with radiation.

If you can get one less person, you will get one less person.

Even when watching surgery, it is usually performed on a large screen in the treatment room outside the cāo) work room.

Therefore, at this time, Yun Tian was holding a micro guide wire in his hand, because he didn't take into account the problem of having to do surgery alone, Yun Tian couldn't open the pressurized injector alone!

At the moment, it is still a bit troublesome to inject contrast media.

"Do you need to open the pressurized injector?" Yun Tian was thinking about how to complete the work of opening the pressurized injector by himself, when suddenly a familiar voice came.

Yun Tian turned around and saw Director Yan walking in.

Director Yan originally planned to push the previous patient away and take the opportunity to escape.

Unexpectedly, Leng Chengye was very protective of food, and he was unwilling to give himself even a job of pressing to stop bleeding.

Director Yan and Leng Chengye had just stared at each other for a long time, and Director Yan gave up his plan to push the patient away.

Forget it, even if you don't push the patient, it's not a big problem to slip through the locker room by yourself.

So Director Yan was about to sneak away, but when he passed through the disposal room, Director Yan walked over and took a sneak peek.

Just a glance,

Director Yan couldn't move.

At that time, what appeared on the screen was the picture of the cloud sky micro-guidewire entering and starting to travel in the femoral artery.

Director Yan is in his forties, and he is in the prime of life as a doctor.

The level of technical work and understanding has been quite high.

Moreover, although Director Yan has a lot of thoughts, after all, it is business, and the pursuit of business is naturally higher than those careful thoughts.

So just a simple glance, I was deeply attracted by the cloudy sky, and I couldn't move my footsteps anymore!

Fast!

Permit!

Vicious!

Elegant!

Tianxiu!

This is Director Yan's response to Yuntian cāo)

The full feeling of making.

Therefore, when he saw Yuntian pushing the microguidewire to reach the vicinity of the vertebral artery, Director Yan sensitively realized that the next step was to open the pressurized injector.

In the entire cāo) room, there was only one person in Yuntian at this time, and Yuntian had no way to open the pressurized injector, so the next operation was inevitably blocked.

Such a refreshing operation may be interrupted because there is no assistant, and Director Yan instinctively feels uncomfortable.

Therefore, Director Yan's first thought was to prevent this uncomfortable thing from happening!

And the best way to stop this from happening is to rush back to the disposal room immediately and help Yuntian complete the work that must be done by assistants in this step.

At this time, the share, status, fame and fortune were all left behind, and Director Yan was full of only let this operation not be interrupted!

Therefore, Director Yan walked back to the disposal room as soon as possible.

And subconsciously walked to the side of the pressurized injector.

Yun Tian didn't understand why this person, who had just wanted to snatch his own surgery, suddenly changed his mind and was willing to help him.

But as long as you don't rush to have your own surgery, everything else is negotiable.

"Yes, turn on the pressurized injector, I'm sorry for you. Yun Tian said politely.

Yuntian's sudden politeness made Director Yan stunned for a moment.

Didn't you just stare at yourself fiercely?

Why is it suddenly so polite and polite?

But

Most of Director Yan's mind is focused on whether the operation can go smoothly.

As soon as these thoughts floated up, they were suppressed again.

Walking here, the pressurized injector is turned on, and with the injection of contrast medium, the image of the vertebral artery and its branches appears clearly on the screen.

"Yes, there is a stenosis at right angles, and I didn't find this stenosis during the preoperative imaging!" Director Yan couldn't help but be stunned when he saw the image on the screen.

The patient's condition is very familiar to Director Yan.

Because the two patients were both through the hands of Director Yan.

The patient's image only showed that there was stenosis in the middle of the basilar artery, but the angiography at this time showed that the middle of the basilar artery was narrowed backward, sending out a small vascular branch, and the stenosis at least 50% of the branches reached more than 50%.

The point is that the stenosis is located right at the right-angle turn of the small blood vessel.

Vascular stenosis at right angles is another challenge to intracranial stenting.

The blood vessels are at right angles, but there is no stent at right angles that can be used, so it is very difficult to dilate the plaque at the right angle.

The current cāo) work is generally expanded in stages.

Segmental dilation refers to the placement of a stent on each of the two edges at right angles to dilate the plaque at right angles.

But brain tissue is soft and tender.

It is not like the tissues of other parts of the body can hold the blood vessels steadily, and it cannot bear too much weight.

Therefore, when two stents are implanted at right angles, the support is the biggest problem.

First of all, implanting a stent cannot change the morphology of the blood vessel.

Every small part of the brain tissue has a specific function.

Once the shape of blood vessels changes, it may affect brain function.

In addition, the support of the implanted stent should be calculated accurately.

The brain tissue is very tender, and once it exceeds its capacity, the brain tissue may be compressed and cause edema, local congestion and other conditions!

Therefore, right-angle stenosis has always been a difficult surgery for intracranial stenting!

At this time, the patient's basilar artery branch has right-angle stenosis, which will inevitably affect the patient's postoperative results if not treated.

If treated, the basilar artery branch is narrowed at right angles, which is not an easy task to deal with.

"Director Shao's patients are really carefully selected!" Director Shi glanced at Director Shao and said lightly.

At this time, as the imaging image appeared on the screen of the conference room, the entire conference room exploded again!

"Damn, the three branch blood vessels are stenosis at right angles, this is a jackpot!"

"The first case is a high-risk patient with high perfusion, and the second case is a right-angle stenosis!
