Chapter 900: Intimate Contact Between Balloon and Stent

"Isn't the stent on the anterior descending limb?" Jin Miao paused.

The coronary blood vessels of the heart have three main branches.

On the left side, downward from the left main trunk, it is divided into the anterior descending branch.

Also on the right are the right coronary artery and circumflex artery

Other blood vessels are small branches of these blood vessels.

Lu Chen shook his head slightly, "Jin Miao, take a closer look here!"

He points to a narrowing on the coronary angiogram.

Here is the bifurcation of the blood vessels, at an extreme angle.

"Huh? No way...is this here?"

Jin Miao showed a look of surprise.

He had noticed the narrowness here before.

But he thought it was a stenosis of the blood vessels that had formed again after the first operation, and he did not realize that it was the first stenosis.

Lu Chen said seriously: "This should be the first narrowing, and the position of the bracket is below the narrowing!"

Jin Miao was stunned, "Director, are you saying that the stent placed on the patient for the first time has shifted?"

After the stent is displaced, the previously narrow area is exposed again.

Lu Chen nodded slowly.

He had pored over the coronary angiography images.

Now there is only one possibility to explain the problem that the balloon cannot pass.

However, this bracket has been in place for five months!

Under normal circumstances, the stent has long been endothelialized, so how can it be displaced?

"Lao Gu, where was the patient's first stent made?" Lu Chen looked back at Gu Xinyue in confusion.

"I heard from family members that it was done at the No. 1 Hospital in Shanghai." Gu Xinyue looked through the medical records. "What is recorded in the medical records was also done at the No. 1 Hospital in Shanghai, by Professor Zhang Shuqing's team."

"Huh? Did you do it at my mentor's place?"

Lu Chen was stunned.

"Yes." Gu Xinyue nodded.

"Lao Gu, then you suggest to my teacher that they bring over the original video data of the first surgery." Lu Chen ordered.

"OK."

Gu Xinyue immediately took action and contacted the doctor at the No. 1 Hospital in Shanghai.

…

Half an hour later.

Gu Xinyue mentioned Lu Chen's name and quickly obtained the surgical video information.

"Look, it is indeed here!"

After opening it, Lu Chen immediately saw the narrow area.

"The bracket has shifted!"

Although they found out the problem, everyone was a little silent.

Stent migration, a complication, is extremely rare.

No wonder patients still feel chest tightness and pain after implanting the stent.

"There is another problem." Lu Chen said in a deep voice, "The narrow part is at the bifurcation, and the angle is too big!"

The angle is too big and it is difficult for the balloon to pass.

This is one of the reasons why the balloon cannot go in or come out.

"Let's suspend the surgery first." Lu Chen ordered, "All doctors who are not performing surgery should come to the office for a meeting first to discuss."

It was extremely rare for Lu Chen to stop the operation.

Everyone can also feel the difficulty of this operation.

In the office.

Lu Chen and Dai Wansong sat at the top, while other doctors sat scattered around.

On the podium, on the projector, the patient's angiographic images are constantly being projected.

At this time, Lu Chen seemed to be silent and his eyes were deep.

In fact, his consciousness has entered the system virtual space and started virtual training of "stent" displacement.

There was no way, the stent was displaced, and even Lu Chen had not operated it.

Now we can only sharpen our skills before the battle and rely on system simulation to perform common sense operations.

“Let’s all brainstorm ideas.”

Seeing that Lu Chen didn't say a word, Dai Wansong thought he was stumped, so he asked everyone.

Everyone below had seen this situation before, and they were all discussing it, but they couldn't explain why.

Seeing time passing by slowly, if a suitable method is not found, this operation will have to be suspended.

Jin Miao was a little anxious.

As the chief surgeon of this operation, he was under tremendous pressure.

He looked at Lu Chen on the stage from time to time.

Director Lu was found to have a serious expression and said nothing.

In his heart, he became even more anxious.

Half an hour later.

Dai Wansong shook his head slightly, seeing that there was no other way, "Forget it, how about we do it at another time?"

He glanced at Lu Chen.

At this time, Lu Chen's consciousness had virtually exited the system.

He gathered his thoughts.

"Dean Dai, let me do it."

This simple sentence shocked Dai Wansong.

"Lu Chen, what did you say?"

Once you take over such a difficult operation, you have to be responsible to the end.

If he fails, it will have a certain impact on the reputation of the Five Academy of Magic City.

More importantly, in the minds of everyone.

Lu Chen's areas of expertise are in TAVR and electrophysiology.

As for the coronary artery, Lu Chen's technical level has not yet been recognized by everyone in the Magic City.

"I just thought about it and tried it with a cutting balloon and a drug balloon."

In the system virtual space, Lu Chen tried many methods and finally settled on cutting the balloon.

"Lu Chen, you can try cutting the balloon, but for such a large angle, the blade of the balloon can easily get hung on the stent mesh."

Dai Wansong expressed his concerns.

A heart stent is actually a special mesh structure.

To cut the balloon, a surgical blade is combined with the balloon.

When the balloon is opened, multiple blades arranged longitudinally will be propped outward to cut the soft plaques and the inner membrane of the blood vessels to a certain extent, making the balloon easier to open and the blood vessels easier to prop up.

However, when the angle of the blood vessel is too large, the blade cutting the balloon can easily touch the grid hole of the stent.

If it touches, the entire stent will be scrapped!

"I will try my best to control the force and angle." Lu Chen said slowly.

"Ah?"

Dai Wansong was confused.

Interventional surgery is not a simple machine repair.

Angiography images cannot fully show all the conditions in the heart and blood vessels.

If you want the blade cutting the balloon not to touch the stent grid, this operation is very difficult!

"Lu Chen, do you want to slow down?" Dai Wansong hesitated, UU reading www. uuｋanshu.net "We don't need to be so anxious."

"The patient's current condition shows obvious symptoms of angina pectoris. If surgery is not performed as soon as possible, myocardial infarction or even other complications are very likely to occur." Lu Chen said firmly, "President Dai, don't worry, I'm sure!"

In the system's virtual space, Lu Chen has a 95% success rate.

Dai Wansong's mouth twitched when he heard this.

In just a few dozen minutes, Lu Chen was sure?

Dai Wansong was about to reject Lu Chen's proposal for surgery. After all, the Fifth Hospital of Magic City had just been established, and everything was still based on safety.

But at this moment, Gu Xinyue rushed in.

He quickly came to Lu Chen and Dai Wansong and whispered, "The patient had chest pain and chest tightness again on the stage, and the symptoms were quite severe!"
