Chapter 904 Intimate Contact Between Balloon and Stent
"Isn't the stent the lower branch?" Jin Miao paused.

The coronary arteries of the heart have three main branches.

On the left, from the left trunk down, it is divided into the anterior descending branch.

The right side is also the right coronary artery and circumflex branch

Other blood vessels are tiny branches of these blood vessels.

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

He points to a narrowing in the coronary angiogram.

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

"Ah? No way... is it here?"

Jin Miao showed a look of astonishment.

The narrowness here, he had noticed earlier.

But he thought it was the narrowing of the blood vessels that formed again after the first operation, and he didn't realize that this was the first narrowing.

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

Jin Miao was taken aback, "Director, are you saying that the stent that the patient put in for the first time has shifted?"

After the stent is displaced, the previously narrow place 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 brace has been in place for five months!
Under normal circumstances, the stent has long been endothelialized, how could it be displaced?
"Lao Gu, where was the patient's first stent made?" Lu Chen looked back at Gu Xinyue suspiciously.

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

"Huh? Was it done at my mentor's place?"

Lu Chen was startled.

"Yes." Gu Xinyue nodded.

"Lao Gu, then you can suggest to my teacher and ask them to bring over the original video of the first operation." Lu Chen ordered.

"Ok."

Gu Xinyue immediately took action and contacted the doctors of the First Hospital of Shanghai.

……

After half an hour.

Gu Xinyue mentioned Lu Chen's name, and soon got the surgery video.

"Look, it really is here!"

Opening it, Lu Chen immediately saw the narrow part.

"Bracket, shifted!"

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

Stent migration, a complication, is extremely rare.

No wonder the patient still feels chest tightness and chest pain after the implantation of 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!"

If the angle is too large, the balloon will be difficult 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 the doctors who haven't had surgery, please come to the office for a meeting to discuss."

It is 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 the other doctors sat scattered around.

On the podium, on the projector, the patient's angiographic image is continuously projected.

At this time, Lu Chen seemed to be silent, with deep eyes.

In fact, his consciousness has already entered the virtual space of the system, and he has started the virtual training of "bracket" shifting.

No way, the bracket shifted, and even Lu Chen didn't operate it.

Now we can only sharpen our guns and rely on systematic simulations to carry out common-sense operations.

"Let's all brainstorm."

Seeing that Lu Chen was silent, Dai Wansong thought he was stumped, so he asked everyone.

When the people below saw this situation before, they discussed it in a hurry, but they couldn't say a reason.

Seeing the time slowly passing by, if we don't come up with a suitable method, this operation can only be suspended.

Jin Miao was a little impatient.

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

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

It was found that Director Lu had a serious expression and didn't say a word.

In his heart, he became even more anxious.

After half an hour.

Dai Wansong shook his head slightly, seeing that there was no way out, "Forget it, why don't you do it again at another time?"

He glanced at Lu Chen.

At this time, Lu Chen's consciousness has withdrawn from the virtual system.

He collected his thoughts.

"Dean Dai, let me do it."

This simple sentence shocked Dai Wansong.

"Lu Chen, what are you talking about?"

Once this kind of difficult operation is taken over, he has to be responsible to the end.

In case of a miss, it will have a certain impact on the reputation of the Fifth Hospital of Shanghai.

More importantly, in the minds of everyone.

Lu Chen is good at fields such as TAVR and electrophysiology.

As for Guanmai, Lu Chen's technical level has not yet been recognized by everyone in Shanghai.

"I thought about it just now, I can try it with a cutting balloon and a drug balloon."

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

"Lu Chen, although you can try cutting the balloon, but for this kind of big angle, the blade of the cutting balloon is easy to hang on the mesh of the bracket."

Dai Wansong expressed his concerns.

The 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, there will be multiple longitudinally arranged blades propped up to cut the soft plaque in the blood vessel and the intima of the blood vessel to a certain extent, making it easier to open the balloon and prop up the blood vessel.

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

If you touch it in this way, the whole bracket will be useless!

"I try to control the strength and angle as much as possible." Lu Chen said slowly.

"what?"

Dai Wansong was dumbfounded.

Interventional surgery is not a simple repair machine.

Angiographic images cannot fully show all the conditions in the heart vessels.

It is not so difficult to make the blade that cuts the balloon not touch the grid of the stent!

"Lu Chen, do you want to take it easy?" Dai Wansong hesitated, "We don't need to be in such a hurry."

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

In the system virtual space, Lu Chen has been able to have a 95% success rate.

When Dai Wansong heard this, the corner of his mouth twitched.

In just 10 minutes, Lu Chen is sure?
Dai Wansong was about to reject Lu Chen's surgery proposal. After all, the Fifth Hospital of the Shanghai Metropolis had just been established, and everything should be safe.

But at this moment, Gu Xinyue hurried in.

He quickly came to Lu Chen and Dai Wansong, and whispered in a low voice: "The patient has chest pain and tightness on the stage again, and the symptoms are more severe!"
