The patient's piece has been studied many times. The responsible blood vessels have also been found.

Yun Tianyi searched a lot of information in the afternoon and repeatedly studied the relevant materials.

Although there is a detailed description of DA and VF in the data, Yun Tian always feels that there is a layer of fog in front of him, and he does not understand it thoroughly.

Therefore, as soon as he entered the system training space, Yuntian asked the system if there were any relevant skills to learn.

"To learn DA and VF venous sinus-related interventional knowledge, you need to consume a high-level skill book, please confirm whether to learn it. The mechanical sound of the system sounded, answering Yuntian's question.

It's just that Yuntian didn't expect that just the interventional treatment of cerebral arteriovenous fistula requires the use of an advanced technical book!

The advanced skill book that Yun Tian only got yesterday has not been covered yet, and he is actually going to use it.

This is an unacceptable thing for Yuntian, who is developing in the direction of Scrooge.

"Can't you use the Intermediate Skill Book and the Skill Fruit instead?" Yun Tian asked, making a final struggle in order to keep the Advanced Skill Book.

"To learn DA and VF venous sinus-related interventional knowledge, you need to consume a high-level skill book and an experience fruit, please confirm whether you want to learn it. The mechanical sound of the system sounded again.

Wu shattered Yuntian's illusion, not only did not reduce consumption because of Yuntian's bargaining, but also added an experience fruit!

......

"I'm just asking casually, how can you sit on the ground and pay a long price?" Yuntian can't accept it, and he definitely can't accept this kind of immoral industry that bullies consumers indiscriminately!

You must seriously reject this kind of consumer fraud!

"Confirm learning. After Yuntian complained, he quickly replied to confirm the study, for fear that the system would increase the price again.

An experience fruit and a little experience point are enough for Yuntian to buy a bottle of energy potion.

Usually Yuntian is reluctant to use it at all, but today he was pit by the system for no reason, and Yuntian felt that his heart was dripping blood!

This time, although Yun Tian complained, the system didn't seem to care, as Yun Tian's confirmation fell, a green flower with complex lines on each petal appeared in front of Yun Tian's eyes, and entered Yun Tian's mouth and nose with a breath.

A green experience fruit followed, and then in a flash, the whole world of Yuntian seemed to turn green.

The advanced skills book brings a huge amount of knowledge, and the description of the knowledge points is more detailed and easier to understand.

About three hours later, Yuntian woke up,

The advanced skill book not only has a lot of relevant knowledge about DA and VF, but it seems that because of the study of this skill book, Yuntian's understanding of the entire intracranial interventional treatment of embolization has improved to a higher level.

He has a deeper understanding of the anatomical location of various blood vessels in the brain.

When I recalled the patient's film again, not only the responsible blood vessels, but also the patient's entire cerebral vascular imaging was clearly replayed in front of my eyes.

The patient's DA and VF are in the unilateral transverse sinus area, and the blood supply comes from the middle meningeal artery, which is suitable for embolization by venous access

Treat.

After analyzing the patient's condition, the systematic interventional catheterization laboratory rose from the ground.

As soon as the subject was ready, Yuntian began to try to do intravenous access embolization therapy for similar subjects.

Compared with the previous surgery done by Yuntian, the biggest difficulty this time is the use of embolic springs selected by the blood vessels.

However, now Yun Tian has a lot of money, although it costs a lot of money to add an experience fruit in just three hours, but Yun Tian still has nearly 5,000 experience points. Enough clouds to squander.

After redeeming 20 hours of intensive training time at a time, Yuntian began to do it.

The consumables used in the system are still the consumables of domestic prestige, the same hard feel, the previous three procedures need to be cāo) are relatively thick blood vessels, this is every time Yuntian cāo) do this degree of blood vessels, the disadvantages of domestic materials will come out, the micro guide wire is hard, and when the superselection enters the middle cerebral artery, it causes cerebral vasospasm and the operation fails.

The failure of the first case did not hit Yuntian, who was able to reach the branch of the middle cerebral artery in the first overselection, and Yuntian was already very satisfied with his progress.

If the operation fails, the subject will disappear automatically.

In the blink of an eye, the second subject was ready.

Yun Tian didn't know how long he had been trying again and again, until a rapid alarm sounded during the system training, and Yun Tian raised his head a little dazedly.

The 20-hour intensive training period has passed.

But Yuntian has not succeeded once.

However, after these 20 hours of repeated failures, Yuntian also benefited a lot.

Yun Tian could feel that he was not far from success.

After another 20 hours of exchange, Yun Tian exchanged two more bottles of energy potion and took them at one time, and his brain, which was already numb from exhaustion, became clear again.

Take a deep breath and continue with the procedure.

Another 20 hours have passed, and Yuntian has performed nearly 40 surgeries by this time.

Nearly 10 or so embolization units have been successfully completed.

However, the completion rate is basically only about 85%.

Buy two more bottles of Energy Elixir and drink them.

At this time, Yun Tian didn't care about whether there would be any side effects from drinking too much energy potion, more like a crazy paranoid, desperate to complete the idea in his heart, even if it was to shatter his bones.

20 hours of system training time passed again, and Yun Tian, who was so tired that he was completely numb, was directly kicked out of the training room by the system.

It seems that 60 hours in a row is a limit.

I don't know if it's the limit of the cloudy sky, or the limit of the system operation training room.

When Yun Tian returned to reality, he didn't open his eyes and fell asleep directly.

I don't know how long I slept, but when Yun Tian woke up, he only felt sore.

The head is empty, as if the cerebral marrow in the skull has been sucked out by zombies.

Some looked up blankly, and the sunlight shone in through the window of the duty room, which was a little dazzling.

Yun Tian was really tired again, and unconsciously fell asleep again.

This time, Yuntian slept very unsteadily, and kept dreaming

，

In the dream, Yun Tian felt as if he was floating in mid-air, as if he was sinking in the sea, floating and drowning, unable to breathe.

The brain is empty, and the brain marrow that has been sucked out by the zombie does not seem to have recovered.

Yun Tian struggled desperately, but it seemed that the water pressure was too great, and Yun Tian couldn't move at all.

Until Yuntian grabbed a piece of wood shining with warm sunlight and held a small piece of wood, and the wood was the smell of sunshine,

That smell soaked Yun Tian's heart and spleen, and made Yun Tian's symptoms of holding his breath instantly alleviate a lot.

It seems that the whole person has surfaced with the sun-smelling wood.

Yuntian finally fell asleep holding the wood.
