Chapter 726 Lost, but Also Won (Night Shift)

The First Hospital of Shanghai.

The emergency operation room of the catheterization room.

Lu Chen was concentrating on preoperative preparation.

The patient's heart failure symptoms had just stabilized, but under oxygen inhalation, the oxygen saturation was only around 90%, and the blood pressure could only be maintained at hg.

Emergency surgery, unlike ordinary diagnosis, has a much higher risk.

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

Laying the towel, disinfection, and puncture, all in one go.

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

"Is this Lu Chen? What emergency surgery does he need?"

"It seems that he is a patient with severe aortic valve stenosis. That should be an emergency tavr surgery!"

"I think the patient's condition is not very stable. The risk is very high!"

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

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

"Oh? Emergency TAVR operation?" Watanabe was slightly surprised, "I didn't expect you could do emergency here? Then let's take a look first."

Watanabe didn't leave in a hurry, but stopped to watch.

On the side, the dean, director and other people of the same level would 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 beside him: "I remember he seemed to be the chief resident of the cardiology department? Why did he come here to perform surgery?"

Zhang Shuqing lowered his head to think, flipped through the patient's medical records, and whispered: "This patient is in a serious condition and needs an emergency TAVR operation. Lao Zhu and I were not available just now, so only Lu Chen can do it."

"Lu Chen can do emergency surgery?" Liu Jun asked in confusion.

"You can do it." Zhang Shuqing nodded slightly, and then told him about Lu Chen's previous surgical experience and his experience as a tutor in the TAVR class at the Magic City Central Hospital.

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

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

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

However, he certainly could not refuse the island country exchange group's desire to observe.

...

In the operating room.

Lu Chen continued his operation.

First, the choice of approach.

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

The thoracic aorta and abdominal aorta are relatively straight, no obvious calcified plaques are found, and there is no obvious stenosis of the lumen. The bilateral iliac artery-femoral artery course is slightly tortuous.

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

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

Lu Chen stopped the operation.

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

"I told you, emergency TAVR surgery is not easy to do!"

"Look at the patient's ultrasound and CT. This patient has a type 0 bicuspid valve, which is highly calcified. The calcification distribution 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 of the island country also touched his chin, flipped through the medical records in front of him, and muttered: "The heart angle is 62°, the delivery device is more difficult to pass the valve, the valve implantation coaxiality is poor, and it is easier to shift during the release process, which increases the difficulty of the operation..."

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

After thinking for a while, Watanabe still shook his head slightly, and didn't think of a good solution for a while.

This Magic City First Hospital is really unlucky. Why did they have to encounter such a difficult operation? !

…

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

In his mind, the TAVR operation that he had practiced in the system panel in the past flashed.

Puncture, valve delivery, release... and other difficulties kept playing in his mind.

Suddenly, Lu Chen had a flash of inspiration.

He had used an auxiliary method in the system space before, which could deliver the artificial valve to the designated position.

Thinking of this, Lu Chen said to the assistant beside him: "Choose 18mm balloon pre-dilation, L23 Venusa-valve valve, and bring a snare!"

The assistant was a doctor resident in the catheterization room. He was stunned, "Snare?"

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

The assistant understood and immediately took out the snare.

As the balloon pre-dilation entered, Lu Chen began to deliver the valve.

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

He frowned slightly.

What kind of operation is this?

Using the Venusa-valve? And then using a snare?

Looking at the previous operation of this surgeon, he is not a beginner, right?

How could he make such a low-level mistake? !

However, as Lu Chen continued to deliver the valve, with the help of the snare, the Venusa-valve actually successfully reached the predetermined position!

"Is this... over?"

Professor Watanabe was shocked. The two Japanese doctors beside him who had just participated in the surgery had the same expression as him.

"Professor Watanabe, what did this Chinese do?"

"I... I didn't see it clearly, how did he put the valve in?"

Watanabe frowned slightly, staring at Lu Chen closely without saying a word.

At this time, after Lu Chen put the valve in, he began the postoperative ultrasound evaluation.

Postoperative angiography and ultrasound showed that there was no obvious regurgitation and no paravalvular leak, the valve was well placed, the shape was complete, and the preoperative transvalvular pressure difference was 50mmhg.

There was almost no pressure difference after the operation!

Quite a successful operation!

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

"How is it possible?"

"Why can the Chinese do this difficult tavr operation?"

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

...

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

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

And they were experts and could see the tricks.

Lu Chen's operation this time can be said to have filled another gap in the high-difficulty operation of Chinese tavr!

Not only did he use the snare for transmembrane transportation, but he also used the venusa-plus recyclable delivery system to ensure the stable release of the valve while reducing the risk of coronary artery!

With this operation, Lu Chen can definitely be regarded as the ceiling of tavr operation in Magic City and even in China.

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

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

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

...

When Lu Chen walked out of the operating room, more than half of the onlookers had left. UU Reading www. uukanshu.net

"Teacher, is your competition over?" Lu Chen took off his gloves and looked at Zhang Shuqing in confusion.

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