"I know this person, he actually invented many new surgeries in many fields before! There are probably more than a dozen or twenty of the first cases in China, and there are more than a dozen new surgeries in the world! This person is too young, but also too evil! Do you remember that the intracranial basal aneurysm surgery that year was a new surgery he created." An expert sighed.

"Then this person is really a little bit too bad."

"It's not just a few tricks, but an over-strength!"

"Lao Zhou, how did you know him?"

"My senior brother Guo Hongbo recommended it to me..." Zhou Jiayu briefly told the story.

"It turned out to be recommended by Academician Guo, so we will feel at ease. However, we should wait until we see someone first!"

"Of course!"

A week later, Ruan Bin came to the Beijing University Hospital.

Coming to brain surgery.

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

When Wang Guozheng and others met Ruan Bin, both sides politely introduced each other and went straight to the clinic.

After arriving at the consultation room, Wang Guozheng, Zhou Jiayu and others first told Ruan Bin about the details and requirements for this operation.

Ruan Bin remembered it all in his heart, knowing in his heart that he could sit down without krypton gold for this operation. After all, he has several experiences in intracranial interventional surgery, and is still innovative.

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

First, intracranial blood vessels are narrower and more tortuous than coronary arteries and peripherals. They require smaller balloon diameters.

Secondly, it takes a long journey from the femoral artery to the torturous skull, and the unique spraying process can better protect the drugs in the vascular pathway.

Third, the currently commonly used spray drug is paclitaxel. In January 2018 (FDA) issued a risk warning letter to cardiovascular physicians, proposing that "paclitaxel drug-coated balloons and paclitaxel-eluted stents may increase mortality." 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. Relying on its strong R&D strength, Xinwei Medical has overcome numerous technical barriers at the moment when foreign giants monopolize it, and finally completed the world's first rapamycin drug balloon.

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

So its success or failure is very critical!

This is also the reason why a group of them need to find the best surgeon to do it!

In fact, there is no problem with the surgical plan. They also know how to do the operation, mainly during the operation, which requires very meticulous operation.

So, after watching Ruan Bin's previous surgery videos, they still gained confidence in Ruan Bin!

After the negotiations are made.

The next morning, the operation began.

In the operating room.

The patient has completed anesthesia.

The operation is carried out immediately.

Ruan Bin is the chief scientist and Zhou Jiayu is the assistant.

Outside, a group of people were watching the live broadcast of the operation.

Because the patient's left middle cerebral artery is severely stenosis, with a stenosis of about 90%, such severe stenosis makes the operation extremely difficult!

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

As many narrow or even blocked blood vessels as above, many places cannot use catheters to transport rapamycin drugs, so we need to find a way to transport these rapamycin drugs to the designated location as much as possible.

Ruan Bin, the operation began.

He began to choose the approach routinely, first transporting the simplest and easiest vascular pathway to some rapamycin drugs.

Half an hour later.

He made a total of 2 vascular pathways.

However, the rest need to open up new paths.

He started looking for it from the outermost branch vessel.

When everyone saw this, they all became nervous.

They knew that the real challenge was coming.

However, Ruan Bin is worthy of being a cheater.

It seemed like there was a navigation device in his mind. He slowly searched among these numerous collateral blood vessel networks, and first searched for the arterial guide wire bit by bit.

Fifteen minutes later.

He then found the first vascular pathway that could safely transport rapamycin drugs.

The arterial guide wire arrives, then the catheter is transported in, and then the rapamycin drug is then!

Basal ball expansion.

Release the drug!

Completed in one go!

"Huh~ I have completed one, and I need to find a new one next!" Ruan Bin continued to search.

He estimated that he would need to find 4 paths!

Because it is necessary to bypass the patient's stenosis of about 90% of the left cerebral artery!

At this time, Zhou Jiayu and others saw Ruan Bin's fine operation so carefully that they seemed to not make mistakes and felt like they were navigators. They quickly found the first new path, which made them very excited.

"Too strong! How to do it?"

"What if we find a 'way' among so many blood vessel networks?" Wang Guozheng looked at him so hard that he stared at him.

Then, the second item was found by Ruan Bin again.

Then there is the third one...

But at the last time, something happened!

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

There seems to be no newly opened pathway, and the only possibility is to walk the patient's narrow left cerebral artery, which is about 90%, but if you walk this, it is very risky!

Ruan Bin was not sure either!

Because there is a place that is too narrow and I guess the catheter cannot pass through!

"What should I do?" Zhou Jiayu was panicked. She was just one last step away.

"Why don't you forget it. Now that I have put so many medicines in, it can be considered as the purpose of treatment."

"Add from the right cerebral artery, and then see if you can access the left side of the location!" Ruan Bin said in a shocking way.

"Damn..."

Half an hour later.

success!

"Awesome!"

"Ruan Bin, you are really amazing. This time I depend on you so much. Without you, we wouldn't know what to do."

"Hehe, this is a success together!"

...

Three days later, the news came out.

Huaxia Medical News: The "Clinical Trial of Rapamycin Drug Ballistic Catheter for Treating Symptomatic Intracranial Atherosclerosis Stenosis" led by Professor Zhou Jiayu, a well-known expert in China's neuroscience, and Wang Guozheng, an academician of brain science, was currently being carried out in multiple centers across the country. This case is the first case in this trial and the first case in the world to use rapamycin Drug Ballistic Surgery...
