I can see health

Chapter 831 I am an outsider
The left main artery of the coronary artery is one of the most important blood vessels of the heart.

Lu Chen also felt that the patient in front of him was very difficult.

Recalling training in the system's virtual space, he began feeding the guiding wire.

"Bring 2 guiding wires here!"

When the guiding wire slowly occludes the blood vessel, inject Xinweining and prourokinase immediately.

"Contrast again!"

Prourokinase is a thrombolytic drug.

Intravascular thrombolysis can dissolve blood clots and reduce vascular stenosis.

After repeated radiography, it indicated that the proximal to mid-section of the left trunk was severely calcified, and the proximal section was occluded!

"Prepare for pre-expansion!"

Lu Chen said in a deep voice.

Before the stent is implanted, the blood vessel needs to be pre-dilated.

He sent two pre-expanded balloons to the lesion respectively.

At this time, a mutation emerges!
The patient lying in bed suddenly became restless, with a slowed heart rate and low blood pressure.

The bedside electrocardiogram showed frequent ventricular tachycardia.

"Don't panic." Lu Chen calmly said, "It should be a reperfusion injury!"

"A shot of adrenaline!"

The nurse acted immediately.

Subsequently, the patient's heart rate and blood pressure slowly began to rise.

"The patient's lesion is tortuous and has diffuse calcification. The operation is too difficult!" Jin Miao, the surgical assistant on the side, said, "Director, why don't you end the operation? I think the coronary blood flow has recovered. Wait until the patient wakes up." do it?"

Implantation of stents in such heavily calcified blood vessels can easily lead to poor apposition of the stent, and long-term occurrence of stent thrombosis and stent stenosis.

"Wait for the patient to wake up?" Lu Chen frowned, "Can he wake up without surgery?"

Jin Miao was silent.

"Use rotational atherectomy!" Lu Chen thought for a while and said.

Coronary atherectomy, referred to as rotational atherectomy.

It refers to the use of a rotor with ultra-high-speed rotation to grind the atherosclerotic plaque and calcified tissue in the coronary artery into extremely fine particles, so as to eliminate the plaque in the blocked blood vessel cavity.

The operating nurse immediately brought the rotary atherectomy machine over.

The top of the catheter for coronary atherectomy is a metal stainless steel drill bit inlaid with fine diamond particles, which is in the shape of a spindle.

When it rotates at high speed, it can grind atheromatous plaque into fine debris and be flushed to the distal end, and the debris can pass through the capillary bed.

"Director, the patient's vascular calcification is so heavy, it will be even more difficult to use rotary atherectomy if the blood vessel is torn or dissected!"

Jin Miao reminded in a low voice.

In his opinion, Lu Chen has done a good job in restoring the patient's blood flow and the heart's blood supply.

Keep sitting, the stakes get higher and higher!
Especially rotational atherectomy for coronary intima.

Although it is a very good interventional technique, it is also very risky.

Human blood vessels are very fragile.

High-speed rotational grinding can easily damage blood vessels.

Coronary vessels are broken, torn, and dissected, which is another major blow to the patient!

At this time, Lu Chen concentrated his energy.

He took a rotary atherectomy drill and penetrated deep into the patient's blood vessels.

Having reached the most important place for coronary artery calcification, he started the machine.

Everyone present was sweating for Lu Chen.

Especially the assistant Jin Miao, who was closest to Lu Chen.

Every movement of Lu Chen touched his heart.

"continue!"

After spinning a calcified plaque, he didn't stop.

Only by working hard can we survive a hundred battles!

Lu Chen's confidence stems from his practice in the system's virtual space.

Even with systematic assistance, his training has never been interrupted.

From the initial electrophysiological surgery to the current TAVR surgery, Lu Chen has trained hundreds of times in the virtual space of the system for every surgical procedure.

……

When the diamonds for coronary atherectomy stopped rotating, people around looked at the operation images in front of them, and they all breathed a sigh of relief.

Even Director Zuo Yaoqun didn't have this kind of grinding technique, right?

Jin Miao felt the deepest.

As long as Lu Chen's hand trembles slightly, the patient's blood vessels may be injured!
The risk is simply too high...

But when the stent was successfully implanted into the blood vessel, the eyes of everyone looking at Lu Chen changed.

Unexpectedly, Lu Chen's most powerful operation.

Not TAVR intervention, but coronary intervention!

With Lu Chen's trick today, Guanghai's coronary intervention pattern may have to change!
"Okay, it's finally done."

Four stents were successfully implanted into diseased vessels.

Angiography was repeated, and the blood flow recovered to TIMI3 level.

Lu Chen took off his gloves and hat.

Get out of the cath lab.

Everyone came up to welcome them.

"Director Lu, you are really amazing!"

"Director Lu, teach me the rotational atherectomy just now!"

"Don't even think about it! Director Lu, I'm studying TAVR, not coronary artery!"

All of a sudden, everyone was chattering.

Lu Chen raised his hand to signal everyone to be quiet.

"Academic issues will be discussed later."

"Today, this patient is not over yet. The next step is to take care of the patient after entering the CCU. Everyone needs to pay attention."

A middle-aged doctor immediately patted his chest, "Director Lu, don't worry, I'm on duty tonight, and I'll put the patient in the emergency room in front of the office!"

"Okay." Lu Chen smiled slightly.

Afterwards, he and Jin Miao came to the doctor-patient communication room.

……

"The operation was successful." Jin Miao said, "Four stents were implanted, but whether the patient can wake up or not depends on the subsequent recovery."

The eldest son of the patient thanked him repeatedly when he heard this.

"Thank you, Director Lu, and Dr. Jin."

Lu Chen's tone was flat, and he said slowly: "We did our best to do the surgery. The patient's family members and our doctors need to work together to care for the patient."

"Well, I understand, Director Lu." The man showed a slight smile, then checked to see if there was any surveillance nearby, quickly took out an envelope from his bag, and stuffed it into Lu Chen's arms.

"This is our family's gratitude to Director Lu, it's a small thing, don't refuse."

Holding a thick envelope in his hand, Lu Chen said slowly, "Don't even mention it, our doctors are really short of money."

"But we really can't ask for your money."

Lu Chen handed the red envelope back.

The patient's son thought it was a camera in the doctor-patient communication room, so he quickly whispered: "Director Lu, let's go outside and talk about it later."

"No need." Lu Chen waved his hand, "Actually... your family's greatest gratitude to our doctor is trust!"

After saying this, Lu Chen took a deep look at the patient and left first.

The family members of the patients frowning and thinking alone were left behind.

……

Subsequently.

Lu Chen informed Jin Miao and the CCU bed doctor of the postoperative precautions.

He returned to the talent apartment by himself.

Mom and Dad are still at home waiting to have dinner together.

Go home and open the door.

There was a burst of laughter in the house.

Lu Chen took a closer look.

Xu Wei was having a pleasant conversation with Luo Meizhen.

"Ah? Why are you here?" Lu Chen was surprised.

Seeing that Lu Chen had returned, everyone turned their heads.

"You child, how do you talk?"

Luo Meizhen glared at Lu Chen fiercely, "You don't welcome other people as guests?"

"Mom, that's not what I meant." Lu Chen said helplessly.

Xu Wei sat on the sofa, got up quickly and said, "Auntie, don't blame Lu Chen, he just came back from the hospital and should be very tired."

Luo Meizhen looked at Xu Wei with a smile, and pulled her to sit next to her.

"Don't worry about them, let's talk more."

Afterwards, Luo Meizhen glanced at Lu Wenguo, "It's time for you to cook."

Lu Wenguo had no choice but to put down the TV remote control, stood up helplessly, and walked towards the kitchen.

Lu Chen looked at Xu Wei and his mother who were talking happily.

He felt like an outsider himself.

"Well... I'm going to help Dad cook."

Luo Meizhen waved her hand without even looking at Lu Chen, "Go."
