I can see health

Chapter 558 Ruin? !
"Let's go!" Qin Sifeng waved his hand and walked towards No. 3 catheterization room.

Seeing this, the female doctor and Lu Chen also followed closely behind.

On the way, the young female doctor has been silently observing Lu Chen.

Didn't Professor Qin go to pick up a big man just now, why did a young man suddenly appear?

……

Catheter 3 is outside.

Qin Sifeng was not in a hurry to go in, but wanted to understand the patient's condition first.

"what's the situation?"

The young doctor outside the catheterization room immediately said: "The operation went smoothly at the beginning, but there seemed to be some problems during the puncture just now."

After speaking, the young doctor handed the patient's medical records to Qin Sifeng.

Qin Sifeng opened the medical records, and the content on the first page was the patient's echocardiography report.

"This ultrasound... the patient's septal puncture is indeed a bit tricky." Qin Sifeng frowned.

Compared with coronary intervention, the talent pool of electrophysiology is relatively small, and Xiao Shikang is already a leader among the younger generation.

Surgical problems that even he couldn't solve were not routine minor problems.

Lu Chen also saw the patient's echocardiogram, and said in a deep voice, "A bulging tumor in the fossa ovale?"

Qin Sifeng nodded with a serious expression on his face. .

Atrial septal puncture is the most basic step in atrial fibrillation ablation, but also the most dangerous step!
Generally, the puncture point of the atrial septum is in the fossa ovalis.

When puncturing, be sure to only wear on the fossa ovale when puncturing.

If it exceeds the fossa ovale, it may cause cardiac tamponade!
In addition, the position of the puncture point is also related to the patient's body shape and heart shape and structure.

Some people are slender and have a vertical heart, so the puncture generally needs to be higher.

If it is low, the catheter passes under the fossa ovale and reaches the bottom of the atrium.In some people, the left atrium is very small, and once it passes through, it reaches the opposite side of the left atrium, causing cardiac tamponade!
If it is a transverse heart, the puncture should be lower. If it is higher, it may pass through the roof or even the pulmonary artery, and the aorta will be pierced anteriorly.

In addition, the puncture should not be too fast, if the puncture is too deep, it may go to the opposite side.

"Ms. Qin, may I get you a lead coat?" asked the young female doctor beside her.

Usually at times like this, Qin Sifeng would come on stage in person.

But today...

Qin Sifeng looked at Lu Chen beside him, there was no need for him to do it himself!
"No need." Qin Sifeng shook his head slightly, and pointed to Lu Chen beside him, "Find him a suit that fits well."

Hearing Qin Sifeng's words, everyone around looked at Lu Chen with surprise expressions on their faces.

There is a lot of turnover in the catheterization room, and a small number of people think that Lu Chen looks familiar, but they didn't match the number for a while, and just regarded Lu Chen as a doctor in the general ward upstairs.

Lu Chen smiled faintly, he had expected this situation a long time ago.

Mr. Qin brought him to the catheterization room, but he didn't intend to let him "watch a show" aside!

"Find it for him?" The young female doctor had never seen Lu Chen before, and her expression was a little hesitant. Could such a young doctor do it for a question that Teacher Xiao couldn't figure out?
"Don't waste time!" Qin Sifeng urged.

The young female doctor didn't dare to be negligent, and put aside all distracting thoughts in her mind, and hurriedly prepared to find lead clothes for Lu Chen.

"Don't bother you, I'll find it myself." Lu Chen smiled.

He once stayed in the catheterization room of the First Affiliated Hospital of Kyoto University for a month.

I am quite familiar with the environment here.

He found a set of lead clothes with ease, and after putting on, he walked into the cath lab.

……

Cath 3 room.

Xiao Shikang was staring closely at the angiographic image in front of him.

This is a case of radiofrequency ablation of atrial fibrillation, but he had trouble with the transseptal puncture.

Because in the contrast image, he saw a bulging tumor in the fossa ovale of the patient's atrium.

Fossa ovalis is very soft and elastic, and it is not easy to pass through.

As the left atrium is small, special care must be taken in puncturing. Once the puncture needle passes through the bulge, it will push against the free wall of the left atrium, which may cause the risk of cardiac perforation.

Even under the guidance of echocardiography, Xiao Shikang flinched.

Because if there is any mistake, the patient's heart is at risk of perforation!
"Did you tell Professor Qin?" Xiao Shikang asked the graduate student who was following the stage.

"Alright, Professor Qin will come over right away," the graduate student said.

Xiao Shikang nodded slightly, now he can only wait for Qin Sifeng's arrival to see if he has any better way to puncture.

Just as Xiao Shikang was staring at the radiography images in a daze, a familiar yet somewhat unfamiliar voice suddenly sounded beside his ears.

"Mr. Xiao, I'm here."

Xiao Shikang immediately looked back, and at some point, there was a doctor in surgical gown beside him.

He was wearing a mask and hat, and Xiao Shikang couldn't see his appearance clearly.

But listening to his voice and looking at his piercing eyes, Xiao Shikang felt very familiar.

"You are……"

Lu Chen narrowed his eyes and smiled, "Mr. Xiao, I'm Lu Chen. I haven't seen you for a year. Don't you remember me?"

Back then, when Lu Chen came to Kyoto Electrophysiology Institute for the second round of assessment, he studied under Xiao Shikang.

"Lu Chen?" Xiao Shikang was stunned, the figure in his mind slowly merged with the person in front of him, and a look of surprise appeared on his face, "You, why are you here?!"

"Ms. Xiao, wait until the operation is over before talking about the old days. Let's take a look at this patient first." Lu Chen smiled.

"Okay!" Xiao Shikang nodded slightly, and began to tell Lu Chen about the patient's condition.

The patient was a female patient in her 60s who was diagnosed with paroxysmal atrial fibrillation.

In recent years, she suffered from frequent episodes of atrial fibrillation, and each episode had symptoms of angina pectoris, which made the patient suffer a lot.

After much consideration, I finally made up my mind to do atrial fibrillation ablation surgery!

When the operation started today, everything went well.

But when it was his turn to puncture the septum, Xiao Shikang felt something was wrong.

……

"Lu Chen, have you seen the patient's preoperative echocardiography?" Xiao Shikang asked.

"I've seen it." Lu Chen nodded, "The patient has a bulging tumor of the fossa ovalis. This tumor is soft and large, and it is not easy to puncture it. Once it touches the free wall of the left atrium, the heart is easily perforated. .”

"Yes, I'm considering this possibility now, so I dare not make a move." Xiao Shikang sighed.

He turned his head slightly, glanced at Lu Chen beside him, and found that he was staring closely at the patient's angiographic image.

"Lu Chen, is there any safe way?"

Lu Chen didn't answer directly, but instead asked: "Have you done the intraoperative ultrasound?"

"I asked the ultrasound teacher to do it just now." Xiao Shikang said, "Do you need to do it again?"

Lu Chen looked at the contrast image and nodded, "Push the ultrasound machine over, and I'll take another look at the exact location of the fossa ovale bulge."

"Okay." Xiao Shikang immediately ordered the graduate students beside him to push in the ultrasound machine outside the catheterization room.

Qin Sifeng, Xiao Shikang and others were not surprised by Lu Chen's superb ultrasound technology.

But outside the catheter room, other young doctors saw Lu Chen's ultrasound skills, and they knew that this young man was extraordinary!
Lu Chen didn't waste too much time, he mainly wanted to use ultrasound to determine the approximate location of the bulge so as to facilitate the puncture direction.

"Now even if the puncture is guided by ultrasound, the risk is not small!" Xiao Shikang frowned deeply.

Anyway, he didn't dare to puncture like this!

Because the risk is extremely high, once it fails, it will be ruined!

Is Lu Chen going to take such a risk?
