This miracle doctor just wants to be fired!

Just then, Zhou Cheng suddenly asked a question that no one had expected.

"Did these patients use IVUS?"

The office fell silent instantly, and the group exchanged glances.

Li Mingyuan immediately flipped through the medical records.

One, two, three, four...

A minute later, his movements slowly stopped, and his expression changed.

"teacher……"

"What's wrong?"

"Only the last case underwent IVUS."

Lin Feng's pupils contracted. "What about the other three?"

"No, the entire assessment was based on imaging."

The air seemed to freeze for a moment.

At this moment, Zhou Cheng finally sat up straight.

He didn't show any relief after finding the answer; instead, his expression was even more serious than in the morning.

He knew that they might have touched the edge of the problem, but had not yet truly found it.

The indications have been expanded, but intracavitary imaging is lacking.

Are these two changes related?

Or is the real reason hidden somewhere deeper?

Zhou Cheng gently turned off the screen and looked at the three students.

"Tonight, everyone go back and do one thing: don't look at papers or guidelines, watch all the videos of the first thirty calcification release surgeries performed at our center again."

"Especially those four complications, I want to know what exactly we changed afterward."

After he finished speaking, he did not assign any further tasks.

The real answer won't be written in any paper; it must be hidden in the surgical details that everyone overlooks.

True scientific research is never about rushing to prove yourself right.

Instead, when data suggests you might be wrong, you're willing to go back and retrace your steps.

……

The hospital's work will not stop because of a scientific question.

The cardiology department's shift handover began as usual at 7:30 a.m. the next day.

The rain outside the window has stopped, and a layer of light gray clouds hangs over the horizon.

The nurse pushed the treatment cart through the ward, the regular alarms of the monitors and the reports from the nurses on duty mingling together, just like any other day.

Only Zhou Cheng knew that things had changed since that phone call yesterday.

He stood in front of the hospital bed, checking the puncture sites of the postoperative patients as usual, asking if they had chest tightness or chest pain, and then confirming the electrocardiogram and test results of the follow-up examination that day.

The entire ward round process was not affected in any way. When a young doctor reported on a patient's condition, he would still stop and ask a few questions about the details. He even corrected a word used in a resident's medical record.

Lin Feng followed behind, but he was clearly distracted.

Others might not be able to tell, but he knew that the calmer Zhou Cheng was, the more important this matter was to him.

After the ward rounds ended and the two left the room, Lin Feng finally couldn't help but ask a question.

"Still thinking about those cases from yesterday?"

Zhou Cheng did not deny it, but handed the medical record in his hand to the resident physician next to him. After the elevator door opened, the two of them went in together.

There were only the two of them in the elevator, and the numbers slowly descended from the tenth floor.

Zhou Cheng gazed at the constantly changing floor numbers and slowly said, "Last night, I reviewed our first ten surgeries again."

Lin Feng was taken aback. "Last night?"

"Um."

"Isn't this for students?"

"They do their thing, I'll do mine."

Lin Feng suddenly didn't know what to say.

Around 9 PM last night, he sent Zhou Cheng a message, intending to discuss matters related to grassroots hospitals. However, he found that Zhou Cheng had not replied, and he assumed that Zhou Cheng had indeed done as he had said and stopped dealing with work after returning home.

In retrospect, he spent all his time on recording.

Thinking of this, Lin Feng couldn't help but smile.

"It seems that your third rule only applies to students, not to yourself."

Zhou Cheng smiled and said, "That's why I didn't reply to you."

"..."

Lin Feng was momentarily speechless, but then he burst out laughing.

The elevator doors opened, and the two walked towards the catheterization lab.

Three PCI procedures were scheduled this morning, the first of which was for a case of severe calcified lesion.

The patient is a 72-year-old male with a history of diabetes for over 20 years. Coronary CTA revealed severe stenosis in the proximal segment of the left anterior descending artery, and subsequent angiography confirmed that the lesion segment was almost entirely encased in calcification.

Li Mingyuan and the other two were all standing in the catheterization lab today.

They did not participate in the operation, but stood in the observation area, watching the real-time angiography on the screen.

Wearing a lead apron, Zhou Cheng stood beside the operating table. After the guidewire slowly passed over the lesion, he did not immediately begin the next step as usual. Instead, he said to the circulating nurse, "IVUS."

Lin Feng looked up at him.

After yesterday's discussion, he changed his habits for the first surgery today.

A few minutes later, the IVUS catheter was slowly inserted into the lesion.

As the image gradually recedes, the cross-section on the screen becomes clearer.

Standing behind, Li Mingyuan observed for the first time how Zhou Cheng viewed IVUS.

Instead of focusing solely on the most severely narrowed area, he worked his way back, looking at the proximal and distal ends, and at the junction of normal blood vessels and lesions.

Then, stop from time to time and have the assistant freeze the image to measure the lumen area and calcification curvature.

The whole process lasted nearly five minutes.

The only sound in the catheterization lab was the operation of machinery.

Finally, Zhou Cheng spoke again, "There's no need to loosen the ties today."

As soon as he said that, Li Mingyuan and Zhao Siyuan were both stunned.

Need not?

They discussed it all night yesterday and both agreed that it was a typical case of severe calcification.

Lin Feng, however, showed no surprise. "Direct pre-expansion?"

"Um."

After a few simple words, the balloon was slowly inserted into the lesion.

Expansion, withdrawal, and re-imaging.

The lesion was successfully opened, and a stent was subsequently implanted.

A final IVUS examination showed that the stent was well attached to the wall, with no gaps or perforations.

The entire surgery went very smoothly.

After the patient was taken out of the catheterization lab, Li Mingyuan finally couldn't help but ask, "Teacher, were yesterday's cases even milder than today's?"

Zhou Cheng took off his lead cap, took the towel handed to him by the nurse and wiped the sweat from his forehead, then retrieved the IVUS image he had just saved.

Why do you think we don't need to relax today?

Li Mingyuan stared at the screen, remained silent for a long time, and finally shook his head.

I can't explain it.

Zhou Cheng didn't rush to explain, but instead stopped the camera on the layer with the most severe lesions. "What you saw yesterday was an angiography."

"What we're seeing today is IVUS; they're not seeing the same world."

Li Mingyuan, Zhao Siyuan, and Chen Yu all looked up at the same time.

Zhou Cheng picked up the laser pointer and gently touched the circle of hyperechoic calcification on the screen.

"The imaging tells us that this area is hard, and IVUS tells us exactly why it is hard."

"Some calcifications are thick, but not extensive."

"Some calcifications, although almost a complete circle, are very thin and can still rupture after balloon dilation."

"There are also some that don't look very narrow, but the real problem lies inside the blood vessel walls."

He paused for a moment, his gaze slowly sweeping across the three people's faces.

"Therefore, I have never stipulated that every time calcification is seen, it must be loosened."

After saying this, he did not continue lecturing, but turned off the computer.

At that very moment, a video that had been playing repeatedly the previous night flashed through his mind.

That was the fifth surgery he performed to loosen calcifications.

In the video, he had already delivered the balloon to the lesion, but he didn't dilate it for a long time. Instead, he performed three angiography scans and sent the IVUS in again to confirm it. Finally, he said softly, "That's enough, stop here."

Thinking of this, Zhou Cheng suddenly stopped in his tracks.

Lin Feng noticed his change and turned to ask, "What's wrong?"

Zhou Cheng did not answer immediately.

He just stared at another monitor screen in the catheterization lab that was still open, his gaze growing increasingly serious.

Because he suddenly realized that they had been comparing what they had done all day yesterday.

But they've never compared them...

When will it stop?!

This is the latest chapter.
