Leng Chengran looked at the image on the screen in disbelief.

The micro-guidewire on the image swims flexibly, and each cāo) selection at the blood vessel branch is extremely precise and smooth.

It seems that Dr. Xiaoyun not only does interventional surgery, but also has a good level!

No

No way!

Leng Chengye felt that he couldn't accept such a thing at all.

Leng Chengye watched as the micro-guidewire flexibly over-selected one blood vessel after another, and finally stopped quietly at the branch of the vertebral artery.

Although Leng Chengran has not formally studied interventional surgery, the steps to do aneurysm embolization are still clear.

The first step to be done before embolization is cerebral arteriography.

The location of the aneurysm can already be determined by the patient's MRI, so at this time, the patient does not need to have a whole brain angiography.

It is not difficult to see from the position where the microwires stay that the surgeon intends to do vertebral artery and its branches.

The posterior inferior artery belongs to the vertebral artery branch, which is why the surgeon will hold the microguidewire in this position.

The intention of every step of Yuntian, Leng Chengye is very clear.

But the more this is the case, the more desperate Leng Chengye finds that every step of Yuntian is decent, but it is completed very accurately!

With the injection of contrast medium, the image of the posterior cerebellar artery appears clearly on the display.

In the fourth segment of the posterior inferior cerebellar artery, a bulging, large tumor is attached to the blood vessel, like a ripe fruit hanging from a tree branch.

This is the time bomb that exists in the patient's skull ---- aneurysm.

The purpose of preoperative imaging is to determine the development of the Wills ring and to fully evaluate the development and compensatory status of each segment and branch of the posterior inferior cerebellar artery. Determine the location, shape, size, strength of the aneurysm, and its relationship to the aneurysm-carrying artery to best work angles and embolization protocols.

During this time, Leng Chengye will take the initiative to learn some theoretical knowledge of neurological interventional surgery whenever he has time to prepare for the trip to the imperial capital.

Therefore, Leng Chengye's mind quickly remembered the meaning of angiogram before cerebral aneurysm surgery.

The surgeon seems to be thinking about these questions as well.

Therefore, on the screen, after the imaging is done, the picture is frozen at this step, and there is no further action.

Leng Chengye looked at the picture on the screen, although he could recall the purpose of observing the image in his mind, but the specific method of doing it Leng Chengye's eyes were dark, and he didn't know at all.

Therefore, Leng Chengye couldn't help but glance at the clouds in the room.

Yun Tian held the micro guide wire in his hand, keeping it in the position when the contrast agent was injected and did not move, and his eyes were firmly fixed on the display screen of the projection device. God was overly focused, frowning, and seemed to be thinking about some complicated issue.

The display screen on the projection equipment and the display screen in the disposal room are connected, and the content displayed on both sides is the same.

Seeing that Yuntian stared at the display screen and didn't make the next move, Leng Chengye felt a hint of joy in his heart.

This intern should have encountered a tricky problem and couldn't deal with it, right?

One

minute

Two minutes

Yun Tian has not moved.

As time passed, Leng Chengye trusted his judgment even more.

Yes, definitely,

It must be this little intern cāo) who can't do it anymore!

After all, aneurysm embolization is very difficult, and an accident will cause the aneurysm to rupture and cause massive intracranial hemorrhage, and then the craniotomy can only be turned.

The last time I came to the hospital, I didn't hear that Xihua Hospital was going to perform an intra-divine interventional surgery, how long has it been until now?

It's been less than two months, right?

How could he, an intern, even take down an operation like intracranial aneurysm embolization?

You must know that it is not easy to study interventional surgery, even with your own skills, you plan to study in the imperial capital for at least one year.

Therefore, Leng Chengye looked at the screen with a sneer on his face.

Look,

Today, I want to take a good look at how this intern and Director Shi will end.

And cāo) as indoors, Yun Tian did not rush to the next step.

It is to observe and adjust the angle of the angiography, and set the optimal embolization plan according to the angiography condition combined with the MRI images in memory.

To put it bluntly, an aneurysm is a bulging mass of vascular tissue on the arterial blood vessels.

It is connected to the arteries, and a rupture can cause massive bleeding.

Interventional embolization is a way to insert a spring plug into the tumor and pack the tumor to block its blood circulation.

However, the placement position, method, and even angle of placement of the spring plug will affect the final treatment effect.

Therefore, Yuntian also summed up some experience in today's several surgeries.

And Mr. Fan and Zhao Lei in the room looked at the image on the display screen for a while, and then looked at the cloudy sky, feeling a little dumbfounded.

Previously, both of them wanted to stay and watch Yuntian's surgery up close.

But when Yuntian started the operation, the two found that the two who stayed under the pretext of assistants not only couldn't help at all, but they didn't even know what Yuntian's intentions were at each step.

Not to mention understanding Yuntian's thoughts in advance and making assistance.

At this time, the two of them realized that even if they won the opportunity to stay in the cāo) work, it was still useless, and this cāo) work was completely incomprehensible.

It seems that there is a reason why interventional surgery is difficult to learn!

This is the only cognition and gain of the two of them staying as assistants this time!

Outside of the work, Leng Chengye felt that Yun Tian had not moved for a long time, and basically determined that Yun Tian was in trouble.

"I didn't expect Director Shi to be so ingenious today, and actually invited us to watch such a wonderful aneurysm embolization failed operation. ”

"Director Shi, this is to use such vivid facts to let us deeply understand the difficulty of learning neurological interventional surgery. Leng Chengye had a habitual sneer on his face, and said lightly.

However, as soon as Leng Chengye's voice fell, the micro-guide wire on the screen moved again.

The micro-guidewire moves slightly forward to push the microcatheter into the vertebral artery on the side of the aneurysm, and the micro-guidewire moves very slowly and easily as before

There is an essential difference in appearance.

And the micro guidewire has been going in and out of that position, and it seems that it has not been able to adjust the appropriate position.

Originally, Leng Chengye was still a little embarrassed when the micro guide wire moved again.

But then seeing the uncertain appearance of the micro guide wire advancing and retreating, Leng Chengye affirmed his thoughts even more.

This intern is definitely incapable and inexperienced, so he is wandering here.

"Director Shi, the most common cause of aneurysm interventional embolization failure is cerebral artery spasm and tumor rupture. ”

"He's an intern, he's still young, and it's only natural that he's a little competitive, but if he's been hovering in this position, if the tumor ruptures, the patient will have to turn his craniotomy. Leng Chengye continued with a mocking smile on the corner of his mouth.
