Chapter 827 I Am an Outsider

The left main coronary artery is one of the most important blood vessels in the heart.

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

Recalling the training scene in the system's virtual space, he began to insert the finger guidewire.

"Bring two finger guidewires over!"

When the finger guidewire slowly occluded the blood vessel, immediately inject Xinweining and urokinase.

"Angiography again!"

Urokinase is a thrombolytic drug.

Intravascular thrombolysis can dissolve blood clots and reduce vascular stenosis.

After repeated angiography, it was shown that the proximal to middle segments of the left main trunk were severely calcified and the proximal segment was occluded!

"Prepare for pre-dilation!"

Lu Chen said in a deep voice.

Before stent implantation, the blood vessels need to be pre-dilated.

He inserted two pre-dilation balloons to the lesion.

At this time, a sudden change occurred!

The patient lying on the bed suddenly became irritable, his heart rate slowed down, and his blood pressure dropped.

The bedside electrocardiogram showed frequent ventricular tachycardia.

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

"Give him a set of adrenaline!"

The nurse took action immediately.

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

"The patient's lesions are tortuous and have diffuse calcification. The operation is too difficult!" Jin Miao, the surgical assistant at the side, said, "Director, why don't we end the operation? I see that the coronary blood flow has been restored. Let's wait until the patient wakes up before doing it again?"

Implanting a stent in such a heavily calcified blood vessel can easily lead to poor stent adhesion, and long-term intra-stent thrombosis and intra-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 rotational atherectomy, referred to as rotational atherectomy.

It refers to the use of a rotor with ultra-high-speed rotation to grind the atherosclerotic plaques and calcified tissues in the coronary artery into extremely fine particles, thereby eliminating the plaques in the blocked vascular cavity.

The nurse at the operating table immediately brought the atherectomy machine over.

The top of the coronary plaque atherectomy catheter is a spindle-shaped stainless steel drill head inlaid with fine diamond particles.

When it rotates at high speed, it can grind the atheroma into fine fragments and wash them to the distal end. The fragments can pass through the capillary bed.

"Director, the patient's blood vessels are so heavily calcified. If the blood vessels are torn or dissected, it will be even more difficult!"

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 restoring blood supply to the heart.

If you continue to sit down, the risks will become higher and higher!

Especially the atherectomy of the coronary endothelium.

Although it is a very good interventional technology, the risks are also high.

The blood vessels of the human body are very fragile.

High-speed atherectomy can easily damage blood vessels.

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

At this time, Lu Chen concentrated his mind.

He took the atherectomy drill and went deep into the patient's blood vessels.

Reaching the most important part of coronary calcification, he started the machine.

Everyone present was worried about Lu Chen.

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

Every move of Lu Chen touched his heart.

"Keep going!"

After grinding a calcified plaque, he did not stop.

Only with one effort can we win every battle!

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

Even with the assistance of the system, his training never stopped.

From the initial electrophysiological surgery to the current TAVR surgery, Lu Chen has practiced each procedure hundreds of times in the system's virtual space.

...

When the coronary grinding diamond stopped rotating, the people around looked at the surgical images in front of them and took a breath.

Even Director Zuo Yaoqun has never used this grinding technique, right?

Jin Miao felt it the most deeply.

As long as Lu Chen's hand trembled slightly, the patient's blood vessels might be injured!

This risk is really too high...

But when the stent was successfully implanted into the blood vessel, everyone looked at Lu Chen with a different look.

Unexpectedly, Lu Chen's most powerful surgery.

It's not TAVR intervention, but coronary intervention!

With this skill shown by Lu Chen today, Guanghai's coronary intervention pattern is likely to change!

"Okay, it's finally done."

4 stents were successfully implanted into the diseased blood vessels.

Repeated angiography, blood flow restored to timi3 level.

Lu Chen took off his gloves and hat.

Walked out of the catheterization room.

Everyone came up to him.

"Director Lu, you are so amazing!"

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

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

For a while, everyone was talking at once.

Lu Chen raised his hand and signaled everyone to be quiet.

"We will discuss academic issues later."

"This patient has not finished his treatment today. You will need to pay attention to the patient's aftercare."

A middle-aged doctor immediately patted his chest and said, "Director Lu, don't worry. I will be on duty tonight. I will 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 very successful." Jin Miao said, "Four stents were implanted, but whether the patient can wake up depends on the subsequent recovery."

The patient's eldest son thanked him repeatedly after hearing this.

"Thank you, Director Lu, thank you, Doctor Jin."

Lu Chen said calmly, "We did our best in the operation. The patient's subsequent care work still requires the cooperation of the patient's family and our doctors."

"Well, I understand, Director Lu." The man smiled, then looked around to see if there were any surveillance cameras, quickly took out an envelope from his bag, and stuffed it into Lu Chen's arms.

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

Lu Chen held the thick envelope in his hand and said slowly, "Don't mention it, we doctors are really short of money."

"But we really can't take your money."

Lu Chen handed the red envelope back.

The patient's son thought there was a camera in the doctor-patient communication room, so he whispered, "Director Lu, let's talk outside later."

"No need." Lu Chen waved his hand, "In fact... the greatest thanks your family can give to our doctors is trust!"

After saying this, Lu Chen looked deeply at the patient and left first.

The patient's family members were left alone, frowning and thinking deeply.

...

Then.

Lu Chen informed Jin Miao and the attending physician of the precautions after the operation.

He returned to the talent apartment by himself.

My parents were still waiting for dinner at home.

When he returned home and opened the door.

There was a burst of laughter in the house.

Lu Chen looked carefully.

Xu Wei was talking happily with Luo Meizhen.

"Ah? Why are you here?" Lu Chen said in surprise.

Everyone turned their heads when they saw Lu Chen coming back.

"How can you talk like that, kid?"

Luo Meizhen glared at Lu Chen fiercely, "Others come to visit your home, and you don't welcome them?"

"Mom, I don't mean that." Lu Chen said helplessly.

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

Luo Meizhen smiled and looked at Xu Wei, and pulled her to sit next to her.

"Ignore them, let's chat more."

Then, Luo Meizhen glanced at Lu Wenguo, "You should cook."

Lu Wenguo could only 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.

"Um... I'll help my dad cook."

Luo Meizhen didn't even look at Lu Chen, and waved her hand, "Go."
