I Can See Health

Magic City No. 1.

Emergency procedure room in the cath lab.

Lu Chen was concentrating on pre-operative preparations.

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

Emergency surgery is different from routine surgery, and the risks are much higher.

Moreover, because of the patient's unstable factors, the operation needs to be completed as soon as possible to avoid another episode of heart failure.

Drape, disinfect and puncture all in one go.

Lu Chen didn't notice at all that a group of people had already gathered outside the operating room.

"This is Lu Chen. What kind of emergency surgery does he need?"

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

"I think this 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, also came over curiously.

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

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

Watanabe didn't rush to leave, but stopped to watch.

On the side, people at the dean, director and other levels 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 on the side: "I remember that he seems to be careful about the chief resident of the internal medicine department, right? Why did he come here to do the operation?"

Zhang Shuqing lowered his head to think, looked through the patient's medical records, and whispered: "This patient is very ill and needs emergency TAVR surgery. Lao Zhu and I were both unavailable just now, so only Lu Chen could do it."

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

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

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

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

Despite this, Liu Jun only felt that Lu Chen's level was similar to, or slightly inferior to, Zhang Shuqing and others.

However, if the exchange group from the island country wants to observe, he will certainly not be able to refuse.

…

In the operating room.

Lu Chen continued his operations.

The first is the choice of approach.

The course of the patient's aortic arch was normal, and there were no obvious signs of stenosis or developmental variation in the openings of the three hairs in the aortic arch.

The course of the thoracic aorta and abdominal aorta was relatively straight, with no obvious calcified plaques and no obvious stenosis of the lumen. The course of the bilateral iliac and femoral arteries was slightly tortuous.

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

The approach went smoothly, but the valve delivery was difficult!

Lu Chen stopped what he was doing.

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

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

"Look at the patient's ultrasound and CT scan. This patient has a type 0 bicuspid valve, which is highly calcified. The calcification is distributed toward the junction of the valve leaflets. The operation is very difficult!"

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

Professor Watanabe from the island country also touched his chin, looked at the medical records in front of him, and murmured: "The heart angle is 62°, which makes it more difficult for the conveyor to cross the valve. The coaxiality of the valve implantation is poor. During the release process, It is easier to shift, which increases the difficulty of operation..."

He didn't care about Lu Chen's operation, but was thinking about what he would do if he encountered this situation?

After thinking about it for a long time, Watanabe still shook his head slightly, unable to think of a good solution for a while.

This No. 1 hospital in Shanghai is so unlucky. Why did it encounter such a difficult operation? !

…

At this time, Lu Chen lowered his head and thought.

In my mind, I flashed back to the tavr surgery I had practiced in the system panel in the past.

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

Suddenly, Lu Chen had a flash of inspiration.

He once used an auxiliary method in the system space to send the artificial valve into the designated position.

Thinking of this, Lu Chen said to the assistant on the side: "Use an 18mm balloon to pre-dilate, a No. 123 Venus-valve, and then bring a snare over here!"

The assistant was a doctor resident in the cath lab. He was startled and said, "Snare?"

"Yes!" Lu Chen said, "The angle of the patient's heart is too big. I want to 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.

As the balloon was predilated, Lu Chen began to deliver the valve.

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

He frowned slightly.

What is this operation?

Use venusa-valve? And then use a snare?

Looking at this surgeon’s previous operations, he is not a beginner, right?

How could you make such a stupid mistake? !

However, as Lu Chen's operation of delivering the valve continued, with the help of the snare, the venusa-valve successfully reached its intended position!

"Is this... the end?"

Professor Watanabe was astonished. The two island doctors beside him who had just discussed the surgery had the same expression as him.

"Professor Watanabe, what did this Chinese do?"

"I...I didn't even see clearly. Why did he put the valve in?"

Watanabe frowned slightly. He stared at Lu Chen closely and said nothing.

At this time, after Lu Chen inserted the valve, he started the postoperative ultrasound evaluation.

Postoperative angiography and ultrasound showed that there was no obvious regurgitation and no paravalvular leakage. The valve was placed in a good position with complete shape. The preoperative transvalvular pressure difference was 50mmhg.

There is almost no pressure difference after surgery!

Quite a successful surgery!

Professor Watanabe can see the ultrasound results clearly through the screen outside the operating room.

"How can it be?"

"Why do Chinese people perform such difficult TAVR surgery?"

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

…

Zhang Shuqing and Zhu Qingshan, who had been observing the operation in the operating room, were very excited at this time.

Others could only notice that Lu Chen suddenly transferred the valve, but did not see the most critical factor.

And they are experts and can best see the secret.

Lu Chen’s operation can be said to have filled another gap in China’s difficult TAVR operations!

Not only the snare is used for transmembrane transportation, but also the venusa-plus retrievable delivery system is used to ensure stable valve release while also reducing coronary risk!

With this single operation, Lu Chen can definitely be regarded as the ceiling for TAVR surgery in Shanghai and even China.

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

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

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

…

When Lu Chen walked out of the operating room, most of the people watching had already left. UU reading www. uukanshu.net

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

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 incomprehensible, and Lu Chen touched his head, a little confused.
