Chapter 629

There was nothing much to say about the previous surgery process; after looking at a few X-rays, Zheng Ren confirmed one point: Professor Rudolf Wagner's description of the condition was still too mild.

Doctor Mei Ha'er's three coronary arteries were basically completely blocked, the myocardium suffered severe ischemia, and only the capillaries provided a meager blood supply.

Without the support of extracorporeal membrane oxygenation to perform blood-oxygen exchange outside the body and reduce cardiac load, Doctor Mei Ha'er would have died long ago.

In the coronary arteries, one could faintly see the shadows of stents filled with thrombus and calcified plaques. Recalling Professor Rudolf Wagner's words, when the guidewire was pulled out, its tip was hanging with a thrombus.

With such a severe coagulation dysfunction, how can we make the patient recover?

Yes, in Zheng Ren's eyes, that old man lying there, kept alive by extracorporeal membrane oxygenation and various machines, was not the old man who held absolute authority over the Nobel Prize in Physiology or Medicine at the Stockholm Karolinska Medical Surgical Research Institute.

He,

just a patient,

just a patient who needs surgical treatment.

"Boss…… everything here is blocked…… is there any hope……" the professor said hesitantly.

"Using coronary artery rotational atherectomy should work; I'm thinking about other things." Zheng Ren said calmly.

Um…… the professor was stunned for a moment.

Coronary artery endarterial rotational atherectomy, also called coronary artery rotational atherectomy shaping, abbreviated as rotational atherectomy.

It refers to a surgical method that uses a Rotablator head with ultra-high-speed rotation to grind the atherosclerotic plaques and calcified tissue inside the coronary arteries into extremely fine particles, thereby eliminating the plaques in the obstructed vascular lumen.

This surgical method was developed in the United States in the 1980s of the last century; after several clinical trials, it received FDA approval in 1993 and officially became a clinical method for treating vascular intimal calcification and plaques.

"Boss, Doctor Mei Ha'er has a C-type……" the professor said softly, then Su Yun stepped on his foot, he was stunned, looked at Su Yun, and said, "Yun Ge'er, what's wrong?"

"Boss is considering the next step, which means rotational atherectomy poses no problem. Don't bring up that C-type vascular opening plaques are a contraindication for rotational atherectomy, or complications like dissection or perforation—don't consider those." Su Yun blew a breath, her black hair fluttering in front of her forehead.

Professor Rudolf Wagner was stunned.

Surgery, if we don't even consider contraindications, what should we consider?

Su Yun's bewitching smile could topple nations.

"Fugui'er, what you should consider is how to convince the people here to let Boss perform surgery on Doctor Mei Ha'er." Su Yun said: "Rather than doubting Boss's surgical skill."

This flattery! The level shoots straight to the heavens!

The professor was dumbstruck, staring blankly at Su Yun, his whole mind in a dazed state.

No wonder Yun Ge'er is Boss's assistant; I can only be considered an outer assistant—look at this level!

But…… the professor had countless questions in his heart, yet couldn't voice them. To speak up would be to doubt Boss's ability?

But doubting now would be the human reaction; still, Yun Ge'er is awesome, never doubting.

The professor suddenly admired Su Yun; only he could reach this level.

Should we completely trust Boss? The professor repeatedly pondered this single question in his mind.

Although the situation is dire, the professor still had a way—maybe he could gamble on Boss's level?

Fine, the Nobel Prize will be within reach in a few years, even though I'm only the second author.

Defeat……

Pah, Boss could never fail.

Professor Rudolf Wagner was giving himself a psychological suggestion.

Learn from Yun Ge'er! I must learn, I'm the man who's going to win the Nobel Prize.

After weighing the pros and cons, the professor steeled himself and made the final confirmation.

"Boss, Dr. Mei Ha'er's condition is extremely complex; what do you think the chances of surgical success are?" Professor Rudolf Wagner bent over, extremely respectful, and asked in a low voice.

"The surgery will definitely succeed; I'm considering what to do if it gets blocked again shortly after the operation. Elderly people's blood vessels have poor elasticity, so next time there may not be another chance to do the rotational ablation." Zheng Ren stared intently at the computer images, answering calmly.

Boss is just boss, he really can do it!

The professor steeled himself; since the boss said it could be done, it definitely could be done.

Recalling the first time he saw the video of prostate interventional embolization surgery, recalling the first time he saw the boss perform TIPS surgery, recalling…

After countless recollections, the professor felt full of confidence.

"Boss, you think about it first; I'll go arrange the surgery for Dr. Mei Ha'er." The professor said through gritted teeth, deciding to put everything on the line: "It might not succeed, but I'll do my best."

"Go on, go on." Zheng Ren waved his hand, like shooing away a fly, and drove Professor Rudolf Wagner away.

This guy is just too noisy, interrupting my train of thought several times.

Zheng Ren intently examined the surgical angiography images, countless similar papers appearing in his mind. Comparing them one by one, he sought a solution to Dr. Mei Ha'er's coronary artery and clotting mechanism problems.

After a long time, a bold plan gradually took shape.

The professor hadn't returned yet; Su Yun sat to the side, fiddling with her phone, occasionally glancing at the image.

Seeing he had time, Zheng Ren immediately entered the System Space and selected surgical training.

The System Operating Room rose up from the ground, and an experimental subject appeared before his eyes.

Even an extracorporeal membrane lung was available; Zheng Ren admired the system's intelligent simulation. It had been a long time since he'd done surgical training, and the Big Pig Trotter's demeanor remained unchanged.

Just as if seeing it for the first time,

Still okay,

Still okay!

Zheng Ren immediately entered the System Operating Room and began the rotational ablation.

Dr. Mei Ha'er's coronary angiography images showed plaque formation at the bifurcations of the origins of the three coronary arteries, which is one of the contraindications for surgery.

And the coronary arteries were filled with thrombi and plaques throughout, which is another contraindication.

Of course, the so-called contraindications are only prohibitions under current technical standards; Zheng Ren is already capable of aiming for peak surgery, and in his view these difficulties are nothing.

For example, the prohibition on angular branching of blood vessels used to be 60 degrees, but now it has increased to 90 degrees as the surgical contraindication.

As technical proficiency continually advances, the so-called contraindications also continually change.

But Zheng Ren's problem is that he only understands the theory; he has never performed a single cardiac interventional surgery.

Let's train for a while; Zheng Ren estimates that he needs about five days of surgical training to finish.

Anyway, his family is wealthy; a few months of surgical training time is no problem.

Moreover, coronary artery surgery is also very important, not a waste.

Zheng Ren calmed his mind and steadied his breath, then began the surgery.

Coronary artery rotational atherectomy uses an olive-shaped burr with diamond particles; according to the principle of 'selective cutting', it selectively grinds away fibrous or calcified arterial atherosclerotic plaques.

The surgery must be done very precisely, so as not to cut elastic tissue and normal coronary arteries.

Place the catheter, guidewire enters, surgical training begins.
