Massimo was about to spurt blood, and the effect of Johannathan's words was equivalent to pressing Massimo's head to the ground.

Yang Ping waited for the next opportunity, if he forcibly risked the risk of voltage instability to go for surgery, it was not in line with his character, the operation must be stable, with a fluke mentality, the beginning would mean failure.

Sometimes there is no way, the risk must be taken, and if there is a way, he is never willing to add a little risk for no reason.

He already had a deep understanding of Steven's condition when he replicated Steven's case for a simulated operation, and he was able to last more than five hours.

If the engineer can fix the power system, he can complete the operation as long as he is left with half an hour.

This kind of surgery must be done under the best conditions, and if you don't shoot, it will be a one-hit kill.

If it really comes to the last moment, the power system is still not repaired, Yang Ping can only be forced to gamble, but if there is a glimmer of hope, Yang Ping does not want to gamble.

Sometimes, life and death are just a thought, although there is no guarantee of foolproof, but Yang Ping will strive for the greatest probability for the patient.

The technical support around Steven's condition has not stopped, and his information has been sent to GG's artificial intelligence doctors, and it has also been sent to IBM artificial intelligence doctors Watson.

GG's artificial intelligence simulated the evolution of Steven's condition, simulated it repeatedly, and the final result came out.

Steven was only able to hold out for seven hours, and died of a burst aneurysm seven hours later.

"Why hasn't he acted? There are only seven hours, and if you don't act, once the time is wasted, it will be too late later. Massimo didn't understand why Yang Ping was waiting, the voltage was unstable, at least he could control the machine, it was a risky thing.

If this operation is to be taken down, it will take five or six hours, and if you wait until the accessories are sent and David Holly comes out of the cabin for maintenance, there will be no five or six hours, so how can there be time for surgery.

Dr. Yang had his own plan, one operation, four cardiac arrests, one arrest and 21 electrical defibrillation sessions before successful cardioversion, but he was still unhurried and confident. Let's not try to understand him with our own thinking, Massimo, you are a genius, I admit it, but you and I are in the same dimension after all, Dr. Yang, is already one dimension higher than us, because he is still young, so you have not yet appreciated his achievements, I believe that in the near future, he will suffocate you, believe in him, more than you believe in yourself. John Mason told Massimo to calm down.

Yang Ping has been staying in the operation room, he can't leave, and he doesn't dare to leave, once Steven is in danger, he has to command Susan to perform first aid, and even use a remote surgical robot to perform some operations.

IBM's Watson reported Steven's diagnosis: "Steven has more than one aneurysm in his brain stem, and there is also a hidden microaneurysm. ”

Compared with GG's artificial intelligence, IBM's Watson is more sophisticated in healthcare.

Of course, it can crush human doctors, no matter how powerful a doctor is, the limit of reading films a day is a few hundred, but Watson artificial intelligence can watch hundreds of millions of films in a few seconds.

On the image and picture, some subtle places, artificial intelligence can be magnified and screened in the computer host, and can also carry out accurate measurement and big data calculation.

Steven has two aneurysms! There is also a hidden one.

This is a far cry from the initial diagnosis, at which point no one would question Watson's diagnosis.

When Johanneson received the news, he immediately couldn't sit still, and he was about to tell Dr. Yang the news that if only one aneurysm embolization was done, it would be equivalent to only one of the two time bombs being removed, and it would still not work.

In the hall of the ground control center, the nerves that the doctors had just relaxed became tense again, and the difficulty of the operation was directly doubled with two aneurysms.

Massimo's last shred of confidence in his heart was destroyed, if there was only one aneurysm, he could still give it a try, betting on the probability of theoretically being better than nothing, two aneurysms in the brain stem, and not even a chance to dream and gamble.

The team of doctors could not control it, and there was a commotion, and Johanneson immediately rushed to Yang Ping's operating room, followed by Massimo.

Yang Ping was drinking tea with Lao Cheng and Mr. Huang, and saw the nervous Johannesen: "The power system has been repaired?" ”

Johanneson shook his head, his face pale: "Dr. Yang, just now IBM Watson's diagnosis: Steven has two microaneurysms in his brainstem, both of which are complex vascular networks, and the other is hidden, riding across the intersection of blood vessels. ”

Yang Ping didn't seem to be in a hurry: "Sit, I'll tell you slowly." ”

"Lao Cheng, bring that picture." Yang Ping greeted Lao Cheng.

Boss Cheng immediately took a pencil drawing drawn by Yang Ping, Yang Ping pointed to the picture and said: "You see, in fact, there are more than two, there is one, there are three in total, but the other two are extremely hidden, not shown, in the microgravity environment, the venous return slows down, the arterial congestion, the first one is the easiest to show, the other two, one is very hidden, the third is not shown at all, it is not clear for the time being that this is Steven's original vascular defect, or a vascular lesion in the microgravity environment." ”

"You --- always known?" Johanneson was puzzled.

Yang Ping nodded: "Because whether it is everyone reading the film, or the artificial intelligence reading of GG company has not found it, if I say it, I can't convince everyone, it will waste a lot of time, anyway, I have to have surgery, I will solve one place and three places at a time, there is no difference." ”

"But --- Watson's diagnosis was only two aneurysms?" Massimo was in a fog and couldn't believe it.

Yang Ping had no choice but to explain to them: "Watson's ability as an artificial intelligence robot depends on all the previous medical knowledge of human beings to feed, all papers, books, images, pictures, etc., if there is no previous knowledge, it has not appeared, it cannot be obtained, so, in the exploration of the unknown, it can not compare with us, it can only find two from the difference in images, we can deduce the third from the mechanism of the disease." Just like the Frenchman Le Verrier and the Englishman John Adams, based on the abnormal trajectory of Uranus, they used mathematical deduction to calculate the existence of Neptune and calculate its trajectory. ”

"You're saying that this aneurysm is currently not visible on imaging, and you deduced it?" Johanneson finally got a little bit of it.

"How can you just speculate and put an extra coil in his skull?" Massimo asked.

Yang Ping's tone was calm, but non-negotiable: "Why not?" If it is too late for it to appear in the image, we need to predict its existence in advance and solve it in advance, just like if Helicobacter pylori is present in large quantities in the stomach, we have to predict that it is very likely to cause stomach cancer, and we cannot wait until the occurrence of stomach cancer to deal with it, but solve Helicobacter pylori in advance. ”

"And its blood flow dynamics have been abnormal, but now no one is looking at it from a dynamic point of view, Watson naturally won't, but I will, isn't all medical diagnosis an inference of evidence? Aneurysms are not inferred from imaging findings? It's just that the basis of my inference is unfamiliar to everyone, I don't deduce from static images, but from dynamic changes, this is a very high reading skill, every minute of the whole brain angiography vascularization is different, you not only have to see the static differences, but also see the continuity of changes between them, the logic of internal drive, their basic principles are governed by the laws of physics, physics is their underlying logic, understand? ”

"I see!" Johanneson didn't want to waste Yang Ping's time anymore, he talked to this high-dimensional creature by himself, how could he figure it out at once, and he could ask for advice slowly in the future, isn't there an online forum, and asked Yang Ping to post a post on the forum to explain in the future.

Massimo didn't understand: "You understand? ”

"Okay, we can't figure it out in a short time, now is not the time for academic discussion, obediently accept this diagnosis." Johanneson whispered in Massimo's ear.

However, Watson only saw two? Where's the other one?

If there were really three, there would be no way to do this surgery.

"I didn't hear him say, one, two, three, for him, there was no difference." Johanneson didn't think much about it at all, it turned out that Dr. Yang had known for a long time.

"But three microaneurysms, this kind of surgery, it will take hours to do one, and the remote surgery system is used, and now he has no intention of doing it, and he is still drinking that damn thing." Back in the hall, Massimo babbled.

Johanneson comforted Massimo: "Don't be in a hurry, he should have made arrangements." ”

But how can he not be in a hurry, Massimo is like sitting on pins and needles, watching the movements of the "safe house" from time to time.

If you have to wait for the power system to be repaired, the time left for surgery will not be more than an hour, and the scary thing is that what if, in case, the blood vessel bursts halfway.

This kind of operation kills three birds with one stone, how can one hour be enough, no matter what, is it not enough, is this Dr. Yang a demigod, he plans to solve the operation within an hour?

An hour? Something you can't think of.

Massimo shivered, similar to the shiver after urinating in winter.

The Soyuz rocket was launched from Baikonur, Kazakhstan, and in about three hours and forty minutes, the spacecraft will complete its docking with the ISS.

David Hawley is about to get out of the capsule, and he's going to do a spacewalk to fix the MDM, and if it can't be repaired, it can only be replaced. He calculated the time to get out of the capsule, and if he was sure that it couldn't be repaired, the ship that was delivered would be docked just in time.

The Russian friend, wearing their Sea Hawk spacesuit, exited the cabin through another exit hatch, sent the accessories over, and then the two of them completed the replacement of the accessories together.

It's a real nuisance, Steven has been unlucky all this time.

David Hawley thought that maybe the last time I talked to him, when we talked about returning to Earth, Steven actually said, "I'm going to miss this place." ”

Damn it, how can you say such a thing.

Yang Ping used the time to drink tea to constantly calculate the operation, enter and exit the system space, and almost uninterrupted the simulation of replicating cases to maintain the latest simulation state.

The extensive network of brainstem blood vessels is tapered layer by layer, forming an extremely complex world of its own.

In the replicating subject, the guidewire goes deeper and deeper, deep into the deepest medulla oblongata, into the nerve nucleus, and in the last section, the guidewire advances almost against the blood vessel wall, little by little, slowly and steadily.

The coil is in place, released! The process is repeated countless times.
