The rarer the blood vessels, the thinner and more tortuous they are, and the more difficult it is to succeed in one-time overselection.

Blood vessels like the hepatic artery, uterine artery, and renal artery are all straight avenues to heaven in front of Zheng Ren's next over-selected blood vessels.

The spinal cord is the most complex artery, and Zheng Ren carefully calculates the dose of contrast agent, like a miser, every injection of contrast agent is carefully analyzed and calculated.

It is feared that after the contrast agent reaches the maximum dose that the body can bear, it will be forced to make the operation unable to continue.

As for the amount of thread that Director Pan was worried about, Zheng Ren was not worried.

The longer he stood in the operating room, the more Zheng Ren did not feel tired, but became more and more energetic, and the operation became more and more delicate.

Looking at Zheng Ren's superselection of spinal cord donor arteries outside, Professor Pei was stunned, and with the success of the superselection, he sighed.

Director Pan was afraid that Zheng Ren had reached the limit of his body, so he immediately asked, "Professor Pei, what's wrong?"

"Director Pan, this resident under you is really amazing!"

"Huh?"

"There is no one-size-fits-all anatomy for the spinal cord's donors, and almost everyone is very different. If I had to do this surgery, I would never have touched the spinal cord donor artery. ”

He paused as he spoke, pointing to the image on the big screen with some excitement.

"If I do it, my body can't bear it anymore at this time. The movements will be out of shape somewhat, and there is no way to be so accurate. You look at Mr. Zheng's methods, which gives me an illusion, and it seems to be getting better. ”

Director Pan was stunned.

Wearing dozens of pounds of lead clothes for nearly three hours, and still getting better? Isn't this a joke?

The ancient generals have all the armor all over their bodies, and the time they can exert their strongest combat effectiveness is also limited.

Zheng Ren was possessed by Changshan Zhao Zilong, who entered and exited seven times?

The superselection of spinal cord donor arteries was successful, and the contrast was still not its blood supply to the upper half of the liver tumor.

At the same time, the people in the operation room were a little happy.

If it is this blood vessel, it means that the operation cannot be continued.

For aortogram, Zheng Ren selected several suspected blood vessels for overselection, but none of them were tumor feeding arteries.

Short stomach ...... Intercostal ...... No signs of blood supply to the tumor were found in the arteries.

It's like looking for a needle in a haystack, Zheng Ren has no other way but to try little by little.

Neither......

Zheng Ren recalled carefully, rummaged through the memories of the master's intervention, and searched for them.

Or is it the phrenic artery? Not sure, the chances are slim, but you need to try it.

Just as he was about to overselect the diaphragmatic artery, Zheng Ren suddenly heard a ding-dong sound in his ears.

[The countdown to the time of the doctor's parents' heart (2) mission begins. 】

[10......]

[9......]

Zheng Ren was stunned for a moment, and he forgot that there was another task.

Glancing at the task prompt in the upper right corner of the field of vision, the completion rate is now 62%, which can barely be considered complete.

[5......]

[4......]

If it ends now, you should be able to claim the reward. Whether it's skill points or experience points, it's all Zheng Ren needs.

But he only hesitated slightly, ignored the voice of the mechanical female voice of the system without emotional fluctuations, and stubbornly and stubbornly began the overselection of the diaphragm.

System tasks?

Let that big pig's trotter fuck off!

If a task is not completed, it is no big deal.

After the mechanical female voice of the system counted down, it disappeared into the air, and Zheng Ren didn't care about it at all, but carefully and meticulously superselected the diaphragm.

Microconductor wire superselection was successful......

Microcatheter access ......

The high-pressure syringe began to inject the contrast agent, and the dose was extremely carefully controlled by Zheng Ren.

As the contrast agent enters the diaphragm artery, 1 second later, the upper part of the liver tumor appears on the large screen in the operation room of the cath lab like a shy girl.

"Wow!" Chu Yanzhi jumped up suddenly.

Chu Yanran exhaled softly, leaning against the wall, she was too nervous before, and once she relaxed, her legs became weak.

Director Pan waved his fist with his right hand, as if he had watched the soldiers brave the enemy's dense artillery fire, climb the main peak, and begin to fight bayonets and take the position.

Professor Pei leaned back on the back of the wheelchair and closed his eyes slightly.

Next, there is no difficulty in the slightest, it is all a routine operation.

The young man ......

I want it!

Ten minutes later, the operation was over.

Zheng Ren took a piece of sterile gauze and pressed the patient's femoral artery puncture point.

Su Yun walked in with his head down, pressed his hand on the gauze, and leaned Zheng Ren away with his shoulder, without saying a word.

This guy was angry, Zheng Ren wanted to say something, but his mouth was still relatively stupid, and he finally held back.

Tearing off the sterile surgical gown and throwing it into the contaminated bucket, Zheng Ren walked out of the operating room.

It's already dark outside, and time flies so fast, Zheng Ren sighed.

A bottle of water appeared in front of him, it was Shay.

Jung in smiled, clumsy thanks.

"Mr. Zheng, thank you. Chang Yue expressed his most sincere gratitude in the depths of his heart.

"It should. Zheng Ren took the pure water and took a big sip.

"Xiao Zheng, come here. Professor Pei smiled and beckoned to Zheng Ren.

Zheng Ren answered and walked over.

"You must have studied in some hospital. Professor Pei asked, "Or maybe you practiced with your tutor when you were in school." ”

Zheng Ren smiled and said nothing.

Professor Pei just expressed his appreciation, and did not want to get an answer.

"After a while, there will be a national annual conference on interventional disciplines, are you interested in attending?" Professor Pei invited.

"It depends, I ...... I'm actually a surgeon. Zheng Rendao.

"Huh?"

"The scope of practice registered with my medical certificate is general surgery. Zheng Ren explained, "Because I was transferred to the emergency department some time ago, I can also do related emergency surgeries. ”

Professor Pei saw that Zheng Ren was in a hurry to explain, so he smiled, "I'm not asking you this, what's the hurry." The level is really good, the talent is very high, and the patience is very good. ”

Zheng Ren smiled a little shy when he saw Professor Pei praising himself.

Director Pan asked with concern: "Are you tired?" Do you want to take a break?"

"Not tired. Zheng Ren stood up straight, his position was just right, and Director Pan punched Zheng Ren in the chest.

This is a habit in the army, and it has the meaning of praise and praise. But in the hospital, no one did this, especially Zheng Ren, who stood for four hours for the operation, and was still wearing dozens of pounds of lead clothing.

Director Pan immediately woke up and was a little embarrassed.

Zheng Ren hurriedly hammered his chest with his fist, making a thumping sound to show that he was fine, like the orangutan who climbed up to the Empire State Building.

"Xiao Zheng, what kind of education do you have?" Professor Pei smiled.

"Graduate student. ”

"I have a place next year to recruit doctoral students, are you interested? No exams, I'll do all the process, you just need to come." ”
