Since the first flight to Malaysia to operate on Guo Jingyao, and later to the United States, Saudi Arabia, and Yemen, although he can't talk about flying to the world, he is also an experienced cross-border flying knife veteran.

Without further ado, Yang Ping arranged Corey's work.

Johanneson is also actively improving the preoperative preparation, the need to remove the eyeball during the operation, there is a risk of losing one eyeball, and it is necessary to communicate with the patient to reach a consensus.

This procedure, which is not listed in the American neurosurgery guidelines, can lose the function of healthy organs in extreme cases, and must not only be reviewed by relevant technologies, but also need to be certified theoretically, and Johannathan has prepared these well.

This is the second time I have been to the United States, and accompanied by Robert, I am going to fly from Nandu to New York and then from New York to Rochester, Minnesota, USA.

New York is Robert's home base, everything is well arranged, and of course Barrell is in charge of picking up the plane.

As soon as he got off the plane from New York and walked out of the gate, Yang Ping saw a red banner in Chinese: Welcome Professor Yang to the United States to guide the work!

In addition to the banners, more than a dozen young Asian, European and American girls wore cheongsams and performed a pop-up mob cheongsam dance at the airport as a welcome ceremony.

Yang Ping couldn't laugh or cry, the last time he came to the United States, he visited Robert's clinic, and the clinic was arranged like the Spring Festival, even the word Fu and Chinese knots were used.

Robert likes bells and whistles, and Yang Ping doesn't say much.

"Welcome to America!" Barrett's Chinese language is indeed improving very quickly.

Robert is very confident, and the professor must feel at home at this moment.

After a break in New York, the next day flew to Rochester, Minnesota, where Mayo's main compound is located.

In order to show the solemnity, Johanneson brought his assistant and secretary to pick up the plane together, and as soon as he got off the plane, Yang Ping ate a light meal and began to work.

The arrival of Yang Ping caused an uproar throughout Mayo, and it was undoubtedly an earthquake for neurosurgery.

In Mayo's history, there has never been a Chinese who has come to perform surgery, and all the Chinese I see are either doctors who come to study or patients who come to treat diseases.

Now this Chinese is invited by Dr. Johanneson to perform the surgery, to be precise, Mayo lacks confidence in this operation and cannot cope with it, and now asks this Chinese doctor to help and guide the operation.

Accompanied by Johannathan, Yang Ping met with the patient Denton, and the neurosurgeons surrounded Yang Ping layer by layer.

Americans, like Chinese, like to watch the excitement very much, so, whether it is a specialist, a resident doctor, or even an intern who has completed residency training, the inner three floors and the outer three floors surround Yang Ping.

What protects the privacy of patients has been left behind by these doctors.

The software engineer looked like a normal person, and Yang Ping had a brief conversation with him to confirm that the patient had no cognitive or language problems. Denton also played on the school's baseball team, worked as a software engineer after college, worked as a principal programmer for a game company, developed a large game, and his wife worked at the post office and had two children after marriage.

After the language exchange, Yang Ping decided to give him a physical examination, which was naturally indispensable for visual touch and percussion and various special physical examination tests, after examination, Denton's skin sensation and muscle strength were not problematic, and there was no problem with the coordination of movements.

Although there are now various advanced instruments and equipment, some physical examinations are no longer necessary.

For example, cardiac examination, now there is color ultrasound examination, and percussion of the size boundary of the heart is a bit meaningless, a waste of time.

However, as a doctor, especially a grassroots doctor, the stronger the ability to diagnose with bare hands, the more you can find the signs of disease.

For example, in the percussion of this patient, Yang Ping percussion on his shaved head slightly, and immediately knew that one side of the head was solid, and the other side of the head was hollow.

If any grassroots doctor could have discovered this surprise, he would definitely have done color ultrasound earlier, and would not have left it until now when he had neurological symptoms to do the first head CT in his life.

Skilled manual diagnostics are very limited, but they can be very useful in special situations.

After seeing the patient, Yang Ping returned to the doctor's office and re-studied the patient's medical records, especially various imaging data, because the pictures were uploaded by Johannesen's WeChat before, which was informal.

Anyway, wherever Yang Ping went, the doctors around him followed, these people were the figures at the top of the pyramid of neurosurgery in the United States, and they formed a few circles, just to see what Johannathan's mentor was like.

Everyone has reservations about this Chinese doctor, and now that they see Yang Ping, who is so young, he can be Johannathan's mentor, everyone's curiosity about Yang Ping must be doubled.

"There are two most difficult points in this case, one is because the brain is a malformed hemisphere, and the distribution and function of all nerve nuclei are different from those of normal brains.

"The projection of the notch is exactly where the eyeball is, so it's best to get in from here, but the eyeball blocks the way, and we have to move it away if we want to get there."

Any surgical approach must meet both the conditions of exposure and safety, that is, it must be able to achieve the purpose of revealing the lesion, otherwise this approach is useless.

Secondly, in the process of revealing the lesion, the safer the better, and it cannot damage the blood vessels, nerves, and other organs.

For example, if the surgery is done and the tumor is removed, the patient dies or has severe cognitive impairment, the operation is a failure.

Johanneson was very studious, and his notebook had already been opened and he began to record the main points of Yang Ping's explanation.

"Pencil?" Yang Ping stretched out his hand.

Robert, who was an entourage, of course, knew the professor's habits, and the pencil and A4 paper had already been prepared and handed over.

"If the eye can't be replanted, it's worth it, but we try to make sure that the eye can be replanted, and after the optic nerve is free, it's better if the optic nerve is long enough for us to remove the eyeball."

As he spoke, on the A4 paper, with a quick pencil stroke, the anatomical diagram of the skull was clearly presented.

The doctors surrounding Yang Ping almost didn't react, everyone crowded with each other, looking at this picture up close, they were all stunned, what a beautiful and clear anatomical diagram of the head with a three-dimensional sense, I had never seen such an anatomical diagram.

The pencil swirled in Yang Ping's hand as if he were doing acrobatics.

"If the optic nerve is not free enough, do I need to cut the optic nerve? If it is cut and replanted, it is unknown whether the optic nerve will be successfully restored. The white-haired doctor asked.

The pencil in Yang Ping's hand turned and stopped: "Actually, we have a second option, even if we can't remove the eyeball, we don't need to cut off the optic nerve, just cut the eyeball, extract part or all of the aqueous humor, and let the eyeball collapse, so that the surgical operation space will be left." ”

Can you still do this? Have you asked an ophthalmologist?

The white-haired doctor was speechless for a while, he didn't expect Yang Ping to say such a second plan, he was simply a god.

"The operation time of the two methods should not be too long, cut off the eyeball of the blood vessels, even if it is protected by ice cubes, it should not be too long, and after the loss of aqueous humor, too long will easily lead to irreversible damage to vision."

A stack of A4 paper, pulled out one by one, with a pencil sketching on it, and several drawings have been drawn.

"You see, here's a diagram of the operation of the eyeball removed, this is a diagram of the incision from the bottom of the eye socket, this is a diagram of the removal of the tumor—"

Is that pencil of yours a magic pen? Why can you paint a picture so quickly, and it is still so delicate and beautiful?

The circle formed by the surrounding doctors began to retract, and Robert relied on his sturdy body to protect Yang Ping from these uninformed people.
