"I know this person, he has actually invented many new surgeries in many fields before! It is estimated that there are more than a dozen or twenty first-of-its-kind surgeries in China, and there are more than a dozen new surgeries in the world! This man is too young, but he is also too evil! Do you remember that the intracranial basilar artery aneurysm surgery was a new type of surgery created by him? An expert sighed.

"Then this man does have two hits. ”

"It's not two hits, it's too strong!"

"Old Zhou, how do you know him?"

"The ...... recommended to me by my senior brother Guo Hongbo," Zhou Jiayu briefly explained what happened.

"It turned out to be recommended by Academician Guo, so we are relieved. Still, let's wait until we meet someone first!"

"Of course!"

A week later, Ruan Bin arrived at Jingcheng University Hospital.

Came to the Department of Brain Surgery.

I also met Zhou Jiayu and other top experts in the field of brain and vascular surgery.

When Wang Guozheng and the others met Ruan Bin, the two sides politely introduced each other and went straight to the consultation room.

After coming to the consultation room, Wang Guozheng, Zhou Jiayu and others first told Ruan Bin about the details and requirements of this operation.

Ruan Bin kept them all in his heart, knowing in his heart that he didn't need krypton gold to sit down for this operation. After all, he has several experiences in intracranial interventional surgeries, and he is still innovative.

At the same time, through communication with the other party, he also learned that this rapamycin intracranial drug balloon encountered many difficulties and barriers in the process of technology research and development and production process.

First, intracranial blood vessels are narrower and more tortuous than coronary and peripheral. A smaller balloon diameter is required.

Secondly, it takes a long distance from the femoral artery to the tortuous intracranial, and the unique spraying process can allow the drug to be better protected in the vascular access.

Third, the currently commonly used spraying drug is paclitaxel, and in January 2018 (FDA) issued a risk warning letter to cardiovascular physicians, proposing that "paclitaxel drug-coated balloons and paclitaxel-eluting stents may increase mortality in the treatment of peripheral arterial disease". The use of safe and effective rapamycin drug technology can effectively inhibit the proliferation of endothelial cells.

Therefore, the rapamycin drug balloon used in this operation is the world's first rapamycin drug balloon independently developed by Xinwei Medical Company. Relying on its strong R&D strength, Xinwei Medical has finally completed the world's first rapamycin drug balloon after overcoming many technical barriers under the monopoly of foreign giants.

Now, Ruan Bin is going to use this rapamycin drug balloon to operate on the patient, the world's first operation!

So its success or failure is very crucial!

That's why a group of them need to find the best surgeon to do it!

In fact, there is no problem with the surgical plan, and they also know how to do the operation, mainly in the surgical process, which requires very delicate operations.

Therefore, after watching Ruan Bin's previous surgery videos, they still have confidence in Ruan Bin!

After the negotiation is settled.

The next morning, the operation began.

In the operating room.

The patient has been anesthetized.

Surgery, immediately unfolded.

Ruan Bin was in charge of the knife, and Zhou Jiayu was the assistant.

Outside, a group of people were staring at the live broadcast of this operation.

Due to the severe stenosis of the patient's left middle cerebral artery, the stenosis is about 90%, and such a severe stenosis makes the operation infinitely more difficult!

The purpose of the operation is to contact the rapamycin coating with the surface of the blood vessels, and during the contact process, rapamycin enters the blood vessel wall to achieve the purpose of treatment!

There are so many narrowed or even occluded blood vessels like the above, and many places simply cannot use catheters to transport rapamycin drugs, so we need to find a way to transport these rapamycin drugs to the designated place as much as possible.

Ruan Bin, the operation has begun.

He began to routinely choose the route, first giving the simplest and easiest vascular access to deliver a portion of the rapamycin drug into it.

Half an hour later.

He had a total of 2 vascular accesses.

But what is left is to open up new pathways.

He started with the outermost branch of the vessel.

When everyone saw this, they all became nervous.

They know that the real challenge is coming.

However, Ruan Bin deserves to be a man who has opened the hanging.

It was as if he had a navigator in his mind, and among the many collateral vascular networks, he slowly searched for it, first letting the arterial guidewire look for it little by little.

Fifteen minutes later.

He found the first vascular access that could safely transport rapamycin.

The arterial guidewire arrives, and the catheter is transported in, followed by the rapamycin drug!

Cyst expansion.

Release the drug!

Coherent!

"Huh~ I've finished one, and I need to find a new one!" Ruan Bin continued to look for it.

He estimated that he would need to find 4 pathways!

Because it is necessary to bypass the left cerebral artery, which is about 90% narrowed by the patient!

At this time, Zhou Jiayu and the others saw Ruan Bin's such a delicate operation, as if they would not make mistakes, and they had the same feeling as navigators, and quickly found the first new path, which made them all excited.

"It's so strong! How?"

"If you find a 'way out' in so many vascular networks?" Wang Guozheng stared at the boss with old eyes.

Then, the second one was found by Ruan Bin.

And then there's the third one......

But when it came to the last one, something happened!

Because Ruan Bin and others found that there was no way to go at the last medicine delivery point.

The only possible way is to take the patient's left cerebral artery, which is about 90% narrow, but this is very risky!

Ruan Bin is not sure!

Because, there is one place that is too narrow, and it is estimated that the catheter will not be able to pass!

"What should I do?" Zhou Jiayu panicked. It's just the last step.

"Forget it, now that so many medicines are put in, it can be regarded as achieving the purpose of treatment. ”

"Approach from the right cerebral artery, and see if you can access this position on the left!" Ruan Bin said in amazement.

"......"

Half an hour later.

Succeed!

"Awesome!"

"Ruan Bin, you are really amazing, this time I rely on you, without you, we don't know what to do. ”

"Hey, hey, it's a success together!"

......

Three days later, the news came out about it.

Huaxia Medical Science News: The "clinical trial of rapamycin drug balloon catheter for the treatment of symptomatic intracranial atherosclerotic stenosis" led by Professor Zhou Jiayu, a well-known expert in Chinese neuroscience, and Wang Guozheng, an academician of the Department of Brain Sciences, as PI......
