Subplaque microvascular branches are those that have small vascular branches under plaques within the cerebral blood vessels.

The plaque in the blood vessels is the moss that grows in the waterways, and the texture is relatively loose.

And under the moss, there is a small tributary that divides out.

In the case of loose plaques, blood flow can still flow through the moss from small branches.

Intracranial vascular stent surgery is like using a net to fix the moss to the edge of the waterway.

When the moss is compressed and fixed, the permeability is weakened, which leads to the blockage of the small tributaries.

Any small blood vessel in the skull plays an important role in supplying blood to the brain tissue in the corresponding area.

If this small tributary is blocked, it will cause strong ischemia and necrosis of the brain group in the blood supply area, resulting in acute cerebral infarction!

This is not very likely.

However, it is a factor that can directly lead to the failure of surgery.

This is almost a contraindication in intracranial stenting.

This situation means that you have no choice but to end the surgery.

The operation was declared a failure.

That's why people have such a reaction.

But Yuntian did not immediately withdraw from the microwire.

"Go to Lao Huang and ask for a small two-size balloon. Replace the stent with a self-expanding closed-loop stent. Yuntian did not end the operation, but instructed Leng Chengye.

"Balloon?" Leng Chengye was only waiting for Yun Tian's order before preparing to end the operation.

After all, if there are small arteries and vascular branches under the plaque, this probability is definitely not more than 1 in 1,000, and such a low probability can only be regarded as bad luck.

There is no choice but to end the surgery!

But Yuntian's order was not to end the operation, but to let himself go to Dr. Huang to get the balloon?

A balloon, as the name suggests, is just a small ball-like thing.

It is often used in interventional procedures for pre-dilation or with stents.

Before the stent placement surgery, the balloon stent was used, and the balloon with stent was inserted to expand the balloon and release the stent.

But at this time, why does Yuntian want a balloon that is two sizes smaller?

Dilate branch blood vessels?

No kidding, the branch blood vessels are as small as a hair, and even a two-size balloon can't get into the branch blood vessels.

And also let yourself change the bracket?

Can this surgery be continued?

Or does Yuntian have other plans?

Pretend to end the surgery?

It doesn't seem like that, does it?

Leng Chengye is completely confused!

However, at this time, Leng Chengye had already been convinced by Yuntian, and he had completely adjusted his mentality, which could be called a qualified assistant.

Therefore, a qualified assistant will naturally not question any decision of the complainant and resolutely carry out the order of the complainant, and such a basic quality Leng Chengye naturally has.

Therefore, Leng Chengye did not hesitate to take off his hand, stepped down, left the cāo) work room, and appeared at the door of the disposal room.

I guess Yuntian asked his assistant to ask if he had finished the operation, right?

Seeing Leng Chengye step down, he walked to the disposal room.

Niu Guanghui felt that Yuntian's business was not as imagined

It's so low, at least before the end of the operation, you know to come and say hello to yourself.

I can understand this kind of thing, but it's just bad luck, and now I can only reschedule the patient with the demonstration surgery tomorrow to re-operate.

However, since Yun Tian knew that he wanted to say hello to him, he should still comfort him and his assistant for a few words.

Niu Guanghui quickly began to organize comforting words in his mind.

"Lao Huang come here. Unexpectedly, Leng Chengye appeared at the door of the disposal room, and did not greet Niu Guanghui, but directly beckoned to Manager Huang of Weixin Consumables.

Niu Guanghui was a little surprised.

Leng Chengye felt that the operation was not done, and he was embarrassed to tell himself, so did he choose the more familiar Manager Huang to speak first?

"Did you bring a balloon and a self-expanding closed-loop stent?" Leng Chengye's words made everyone present stunned.

Shouldn't this be the end of surgery?

When Yuntian's assistant came out, shouldn't he explain to Niu Guanghui that the operation could not be carried out?

Why do you want new consumables from the manufacturer?

Could it be that he can still do intracranial vascular surgery with small blood vessel branches under plaque?

Are you kidding?

There are small blood vessel branches under the plate, and no matter what stent is used, the plaque will be compressed when expanded, thus blocking the small blood vessels.

Is this a problem that a self-expanding closed-loop stent can solve?

Which one is this singing?

Everyone looked at each other, completely confused by Leng Chengye's behavior.

"Uh, that, that, Dr. Yun's assistant," Liu Guanghui said two of them a year, and he didn't remember Leng Chengye's name.

"You told Dr. Yun that the blood vessel branches are relatively small, so they can't be seen in the preoperative examination, which is also a helpless thing, so Dr. Yun doesn't have to be reluctant to end the operation. ”

Niu Guanghui thought for a while, although he didn't know that Bai Yuntian's intention to ask Wolf and Zhipeng to close the loop was the scaffold, he still decided to take the initiative to ask Leng Chengye.

"Okay, I'll tell him that. Leng Chengye nodded in agreement, but his eyes were firmly fixed on Manager Huang, who was flipping through the treasure chest.

"Balloons and closed-loop stents don't need to be used, right?" Liu Guanghui asked Leng Chengye tentatively.

"The small blood vessels under the plaque, can this be done with a closed-loop stent? Tell your boss to come out quickly, there is nothing to be ashamed of ending the operation quickly, it's just bad luck." ”

Seeing that Leng Chengye didn't reply, some of the younger brothers after Niu Guanghui spoke up.

But Leng Chengye still didn't reply.

Stared at Manager Huang tightly, rummaging through his treasure chest.

The intracranial blood vessels are already thin, and the balloon used is even smaller among the trumpets.

Balloons, which are two sizes smaller, are rarely used.

But Manager Huang remembered that he had obviously put it in the box, but the treasure chest was full of all kinds of consumables, so he didn't find it for a while.

"There's no need to die, it's not a shame, this operation can't be done, most of it is a matter of luck,

Hurry up and tell your boss to step down, end the operation, and reschedule the patient tomorrow. Seeing that Leng Chengye had not replied, the other person behind Niu Guanghui continued to persuade.

"Well, my boss said, I want a balloon and a closed-loop stent, I'll bring things in first, and then I'll pass on Dr. Liu's words to him. ”

It's not that Leng Chengye didn't answer before, but he didn't know how to answer.

After all, Leng Chengye didn't know why Yuntian wanted these two consumables.

At this time, Liu Guanghui and the people behind him said three times in a row, and Leng Chengye's mind turned and turned, so he could only answer first.

Leng Chengye is just an assistant, and the surgeon inside has the final say when the operation is over.

So everyone reluctantly agreed with Leng Chengye's answer.

"The balloon was found. Sweating profusely, Manager Huang found a small balloon with packaging from the box and handed it to Leng Chengye.
