I can see health

Chapter 730 I lost, but I also won (night shift tonight)
A hospital in the capital city.

The emergency operating room of the cath lab.

Lu Chen was concentrating on preoperative preparations.

The patient's heart failure symptoms have just stabilized, but under oxygen inhalation, the oxygen saturation is only around 90%, and the blood pressure can only be maintained at 90/60mmHg.

Emergency surgery is different from ordinary surgery, and the risk is much higher.

Moreover, because of the unstable factors of the patient, it is necessary to complete the operation as soon as possible to avoid the recurrence of heart failure.

Drape, disinfection, puncture, all in one go.

Lu Chen didn't notice the operating room at all, a group of people had already surrounded him.

"This is Lu Chen, what kind of emergency surgery does he need?"

"It seems to be a patient with severe aortic valve stenosis, it should be an emergency TAVR operation!"

"I think the patient's condition is not stable, and the risk is very high!"

At this time, the island country exchange group, Professor Watanabe and his doctors came over curiously.

Flipping through the medical records outside the operating room, the translator immediately said to Watanabe: "Dear Mr. Watanabe, this Huaxia doctor is preparing to perform emergency TAVR surgery on the patient."

"Oh? Emergency TAVR surgery?" Watanabe was a little surprised, "I didn't expect you to be able to do emergency surgery here? Let's take a look first."

Watanabe was not in a hurry to leave, but stopped to watch.

On the side, the dean, director and other people will naturally not leave.

Liu Jun glanced at the operating room and found that it was Lu Chen. He was a little surprised and said to Zhang Shuqing who was beside him, "I remember he seemed to be worried about the general manager of internal medicine, right? Why did he come here for the operation?"

Zhang Shuqing lowered his head in thought, looked through the patient's medical records, and said in a low voice, "This patient is seriously ill and needs emergency TAVR surgery. I and Lao Zhu were not free just now, only Lu Chen can do it."

"Can Lu Chen do emergency surgery?" Liu Jun asked doubtfully.

"It can be done." Zhang Shuqing nodded slightly, and then told about Lu Chen's previous surgery experience and his work as a TAVR class instructor at the Modu Central Hospital.

"I know that you are an excellent student. It turns out that you are not only good at scientific research, but also good at clinical operations!"

Liu Jun lamented that the young people of this era also wanted to smack them to death on the beach.

Even so, Liu Jun only felt that Lu Chen's level was similar to that of Zhang Shuqing and others, or slightly worse.

However, if the island country exchange group wanted to observe, he definitely couldn't refuse.

……

operating room.

Lu Chen continued with his operation.

First of all, it is the choice of approach.

The patient's aortic arch can still run, and there is no obvious sign of stenosis or developmental variation in the three hair openings of the aortic arch.

The thoracic aorta and abdominal aorta ran relatively straight, no obvious calcified plaques were seen, no obvious stenosis was found in the lumen, and the bilateral iliac-femoral arteries were slightly tortuous.

After comprehensive consideration, Lu Chen chose the right femoral artery as the main approach.

The approach was smooth, but the delivery of the valve was difficult!

Lu Chen stopped what he was doing.

Outside the emergency room, everyone noticed Lu Chen's movements.

"Let me just say, emergency TAVR surgery is not easy!"

"You look at the patient's ultrasound and CT. This patient has a TYPE0 bicuspid valve with high calcification, and the distribution of calcification is biased towards the junction of the valve leaflets. The operation is difficult!"

"I think it's more difficult than the four operations just now?!"

Professor Watanabe from the island country also touched his chin, flipped through the medical records in front of him, and murmured: "The heart angle is 62°, it is more difficult for the delivery device to pass the valve, and the coaxiality of the valve implantation is poor. Easier to shift, which increases the difficulty of operation..."

He didn't care about Lu Chen's operation, but was thinking, what would he do if he encountered this situation?
After thinking about it for a while, Watanabe still shook his head slightly, and couldn't think of a good solution for a while.

The No. [-] hospital in Shanghai is really unlucky, why did it happen to encounter such a difficult operation? !
……

At this moment, Lu Chen bowed his head in thought.

In my mind, the TAVR surgery I had practiced on the system panel in the past flashed through.

Difficulties such as puncture, valve delivery, and release... were constantly projected in his mind.

Suddenly, Lu Chen had a flash of inspiration.

Once he used an auxiliary method in the system space, which can send the artificial valve into the designated position.

Thinking of this, Lu Chen said to the assistant on the side: "Choose 18mm balloon pre-expansion, L23 VenusA-Valve valve, and bring a snare!"

The assistant is a doctor resident in the cath lab, he was startled, "Snare?"

"Yes!" Lu Chen said, "The angle of the patient's heart is too large. I'll see if I can use a snare to assist in crossing the arch and crossing the valve."

The assistant understood and immediately took out the snare.

With the pre-expansion of the balloon, Lu Chen began to deliver the valve.

Outside the catheter, Professor Watanabe saw Lu Chen's operation.

He frowned slightly.

What is this operation?
With VenusA-Valve?And then use a snare?
Looking at the previous operations of this surgeon, he is not a beginner, is he?

How could you make such a low-level mistake? !
However, as Lu Chen continued to deliver the valve, with the help of the snare, the VenusA-Valve valve reached the predetermined position smoothly!
"This...is it over?"

Professor Watanabe was astonished. The two island doctors beside him who had just participated in the surgery had the same expressions as him.

"Professor Watanabe, what did this Chinese man do?"

"I... I didn't even see clearly, why did he send the valve in?"

Watanabe frowned slightly, and he stared at Lu Chen closely without speaking.

At this time, after sending the valve in, Lu Chen started the postoperative ultrasound evaluation.

According to postoperative angiography and ultrasound, no obvious regurgitation and paravalvular leakage were found. The valve was placed in a good position and the shape was complete. The preoperative transvalvular pressure difference was 50mmHg.

Almost no pressure difference after surgery!
Quite a successful operation!
Professor Watanabe can see the ultrasound results clearly by operating the outdoor screen.

"how is this possible?"

"Why do Chinese people still perform this difficult TAVR operation?"

Watanabe looked at Lu Chen in the operating room with a dark face, the expression on his face was unpredictable.

……

Zhang Shuqing and Zhu Qingshan, who had been operating the outdoor observation surgery, were very excited at this time.

Others could only notice that Lu Chen had suddenly sent the valve into it, without seeing the most critical factor.

And the two of them are experts, and they can best see the way.

Lu Chen's operation this time can be said to have filled another gap in Huaxia TAVR's highly difficult operation!

Not only the snare is used for transmembrane transport, but also the VenusA-Plus retrievable delivery system is used to ensure the stable release of the valve and reduce the risk of coronary artery!
With this one-handed operation, Lu Chen can definitely be regarded as the magic city, and even Huaxia's TAVR operation ceiling exists.

When Zhang Shuqing and Zhu Qingshan looked at the island country medical exchange group, they found that they had left silently.

He didn't even have time to say hello to the dean and director, so he left first...

Seeing that the island country exchange group had left, the dean, director and others also left immediately.

……

When Lu Chen walked out of the operating room, more than half of the onlookers had already left.

"Teacher, is your sparring over?" Lu Chen took off his gloves and looked at Zhang Shuqing suspiciously.

Zhang Shuqing looked at Lu Chen and nodded with a smile on his face.

"Who won?" Lu Chen asked curiously.

"We lost, but we also won."

Zhang Shuqing said something inexplicable, Lu Chen rubbed his head, a little confused.
