There was nothing to say about the previous surgical process, and after looking at a few silhouettes, Zheng Ren was sure that the condition described by Professor Rudolf Wagner was still mild.

Dr. Mehal's three coronary arteries are basically blocked, and the heart muscle is severely ischemia, relying on capillaries to provide a negligible blood supply.

If there was no extracorporeal membrane lung support, blood oxygen exchange outside the body to reduce the workload of the heart, it is estimated that Dr. Mehar would have died long ago.

In the coronary arteries, you can faintly see the shadow of a stent full of thrombosis and calcified plates. Zheng Ren recalled Professor Rudolf Wagner's statement that when the guidewire was withdrawn, there was a blood clot hanging from the end.

With such a severe coagulation disorder, what can be done to make the patient recover?

Yes, in Zheng Ren's eyes, the old man lying inside with extracorporeal membrane lungs and various machines to maintain the flame of life without extinguishing it is not the old man who has nothing to say about the Nobel Prize in biology and medicine at the Carolinsian Institute of Medical Surgery in Stockholm.

he

Just a patient,

Just a patient who needs surgery.

"The owner...... Here, the whole wave is blocked...... Is there any hope...... "The professor said hesitantly.

"With coronary atherectomy, it should be possible, I'm thinking about other things. Zheng Ren said lightly.

Belch...... The professor was stunned.

Coronary endarterectomy, also known as coronary atherectomy, is simply rotational atherectomy.

It is a surgical method that uses a rotor with ultra-high-speed rotation to grind atherosclerotic plaques and calcified tissues into extremely fine particles in the coronary arteries, thereby eliminating plaques in the lumen of blocked blood vessels.

This surgical method was developed in the United States in the eighties of the last century, and after several phases of clinical trials, it was approved by the FDA in 1993 and officially became a surgical method to solve the calcification and plaque of the vascular intima in clinical practice.

"Boss, Dr. Mehal has a C-shaped ......" the professor whispered, and was trampled on the surface of his feet by Su Yun, he was stunned for a moment, and looked at Su Yun, "Brother Yun, what's wrong?"

"The boss is figuring out the next step, which means that there is nothing wrong with rotary grinding. Don't pull the open end plate of the C-type blood vessel is a contraindication to rotational atherectomy, and you should not consider complications such as dissection and abrasion. Su Yun blew a breath, and the black hair on his forehead fluttered.

Professor Rudolf Wagner was stunned.

Surgery, if you don't even consider contraindications, then what should be considered?

Su Yun smiled wickedly, and the country was overwhelmed.

"Fugui'er, the thing you should think about is how to convince the people here to have the boss operate on Dr. Mehal. Su Yun said: "Instead of questioning the boss's surgical level." ”

This sycophant shoots! The level goes straight to the sky!

The professor was dumbfounded, looked at Su Yun coldly, and the whole person fell into a state of bewilderment.

No wonder Brother Yun is the boss's assistant, and he can only be regarded as a peripheral assistant, look at this level!

But...... The professor had a myriad of questions in his mind, but he couldn't get them out. Speaking out, is it questioning the level of the boss?

But at this time, questioning is the human reaction. It's still Brother Yun'er, and he doesn't question it at all.

The professor suddenly admired Su Yun, and he was the only one who could do this.

Do you have to trust your boss completely?

Although the situation is bad, but the professor still has a way, and it is great to learn about the level of the boss?

The Nobel Prize is within reach in a few years, even though he is only the second author.

Fail......

Phew, the boss can't fail.

Professor Rudolf Wagner gave himself psychological cues.

Learn from Brother Yun! You must learn, you are a man who wants to win the Nobel Prize.

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

"Boss, Dr. Mehal's condition is extremely complicated, do you think the operation is likely to be successful?" Professor Rudolf Wagner asked, bending over and very respectfully, in a whisper.

"The surgery will be successful, but what I am thinking about is what to do if it is blocked again in a short period of time after the operation. Older people have poor blood vessel elasticity and may not have the opportunity to have a rotational atherectomy next time. Zheng Ren looked intently at the image on the computer and replied indifferently.

The boss is the boss, and he can really do it!

The professor was resigned, since the boss said it could be done, then it would definitely be possible.

I think back to the first time I saw the video of the prostate interventional embolization operation, and the first time I saw my boss do the TIPS surgery, I think back......

After countless reflections, the professor himself felt confident.

"Boss, think about it first, I'll contact Dr. Merhal about the operation. The professor gritted his teeth and said that he decided to press everything down, "It may not work, I will do my best." ”

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

This guy was so noisy that he interrupted his train of thought several times.

Zheng Ren was intently looking at the video data of the surgical imaging, and countless similar documents appeared in his mind. Comparing them one by one, Zheng Ren was looking for a solution to Dr. Mehal's coronary artery and coagulation mechanism problems.

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

Before the professor came back, Su Yun sat on the side, fiddling with his mobile phone, glancing at the image from time to time.

Seeing that he had time, Zheng Ren immediately entered the system space and clicked on surgical training.

The operating room of the system rises from the ground, and a test subject appears in front of him.

Even the extracorporeal membrane lung is there, and Zheng Ren is also very impressed by the intelligent simulation of the system. It's been a long time since I've been training for surgery, and the temperament of the big pig's trotters has not changed.

But if you first see it,

OK

OK!

Zheng Ren immediately entered the operating room of the system and began to perform rotational atherectomy.

Images from Dr. Mayhar's coronary angiography showed plaque formation at the branches of the origin of all three coronary arteries, which is one of the contraindications to the procedure.

The coronary artery is full of thrombosis and plaque, which is one of the contraindications.

Of course, the so-called contraindications are only taboos at the current level of technology, and Zheng Ren is a person who can already covet peak surgery, and these difficulties are not a problem in Zheng Ren's view.

For example, the contraindication of angulation of vascular branches, in the past, 60° was a contraindication. Nowadays, it has been increased to 90° is contraindicated.

The level of technology is constantly improving, and the so-called contraindications are constantly changing.

But the problem with Zheng Ren is that he only understands the theory, and he has not even done a cardiac intervention.

Let's train for a while, Zheng Ren estimates that it will take about five days of surgical training to complete.

Anyway, my family has a big business, and a few months of surgical training time is not bad.

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

Zheng Ren calmed down and began the operation.

Coronary atherectomy is a rotational head with diamond particles in the shape of an olive shape, which selectively removes fibrotic or calcified arteriosclerotic plaque according to the principle of "selective cutting".

The surgery is done very delicately so that the elastic tissue and normal coronary arteries are not cut.

Catheterization, guidewire insertion, and surgical training begins.
