Brain science research has confirmed that there is a critical period in the process of brain development, during which the brain has a strong ability to adapt and reorganize in structure and function, and it is easier to establish brain function during the critical period than after brain maturity.

Carotid adventitia dissection is one of the effective treatments for severe cerebral palsy, which treats cerebral palsy by removing the sympathetic nerve bundle around the common carotid artery to improve the blood supply to the patient's brain.

Approaching three o'clock, the conference room was already full, and there were neurosurgeons from almost all hospitals in Nanyao City and a group of young nurses from the affiliated hospital who rushed to hear the news.

Later, the doctors looked at the beautiful girls in the first few rows wearing various evening dresses, and thought that they had gone to a large blind date venue.

He Zhen, who was sitting in the middle of the participants covered with gauze, couldn't help but sigh that people like Yi Sheng could boost the GDP of Nanyao City when they came to participate in an academic exchange meeting, but when he was eating, he saw a lot of little nurses who didn't have time to go home to change clothes and ran to the shopping mall next to them to make a big purchase.

At three o'clock, everyone on the rostrum had already arrived except Yi Sheng, and Li Shangai, as the initiator of the academic exchange meeting, temporarily assumed the role of host.

First of all, I would like to inform you that the Affiliated Hospital of Nanyao Medical College recently performed a case of resection of brainstem glioma, and the patient has a good prognosis and can be discharged smoothly. ”

There was warm applause at the scene, Li Shangai nodded with satisfaction and said: "The difficulty of this brainstem glioma surgery is how to ensure the separation of blood vessels and nerves connected to the tumor, Academician Feng Jizong questioned the doctors involved in the neurovascular separation in this hospital, so in order to prove that the doctors of the Affiliated Hospital of Nanyao Medical College do have the ability to separate nerves and blood vessels, we will conduct a live operation broadcast before the start of the conference, please watch the big screen." ”

The big black screen suddenly lit up, and in the picture, Su Jin and Hao Zhe were preparing the instruments, and the two quickly counted the instruments needed for the operation and the various examinations of the preoperative work, while in the corner of the picture, two doctors in green brush suits were whispering to an MRI image.

"This operation is a patient with severe cerebral palsy, and the carotid adventitia dissection is used to remove the sympathetic nerve bundle around the common carotid artery, so as to comprehensively improve the child's brain function, enhance intelligence, memory and language ability, reduce limb muscle tone, and alleviate symptoms such as slurred speech, inflexibility of hands and feet, unsteady walking, and drooling. ”

Although almost all the doctors in the audience were neurosurgeons, Li Shangai still explained to everyone in the hope that the nurses in the front row with fragrant sideburns would not be bored, but the nurses in the audience didn't care about what surgery they did, they only cared about the people who did the surgery.

Compared with the tension of making a paper report in the conference room, Yi Sheng in the operating room seemed extremely relaxed, and this operation was originally operated by Meng Xianyang, and Yi Sheng was only responsible for one of the steps, so there was no burden at all.

Yi Sheng is using 3D holographic tomography technology to simulate the patient's carotid artery surrounding conditions with his eyes closed, although the Xiaoyixian system does not impart knowledge about the carotid artery, but Yi Sheng still relies on a solid anatomical foundation to analyze the degree of carotid artery blockage and the location of the surrounding nerves.

"Ready. Su Jin raised her head after pressing the monitoring equipment on the patient and said that the operation would be broadcast live, so Su Jin did not giggle as usual, and everything was carried out in accordance with the norms of teaching surgery.

As for Hao Zhe, Hook Man didn't have any say in this operation, and he didn't even have to say anything.

After the anesthesiologist completed the general anesthesia operation, Yi Sheng and Meng Xianyang, with the help of their respective assistants, put on surgical gowns and stood in the position of the first assistant and the chief surgeon.

The camera probe swept over Yi Shengde's side face when adjusting the angle of view, and the mask could not hide Yi Sheng's angular outline, which attracted a group of nurses under the rostrum to shout.

Yu Xiangen quietly leaned his head close to Kang Zhenye and whispered: "Lao Kang, you also boasted of being a beautiful man back then, why didn't you see you so attractive?"

"At that time, how can it be compared with now, when you used to walk on the street and you stared at other girls, the girl must have lowered her head and accelerated her pace, and now you look at the girl on the street, she can stare at you in turn until you lower your head and speed up your pace, understand?" Kang Zhenye sighed and said.

While speaking, Meng Xianyang had already made a longitudinal incision on the medial and medial edges of the patient's bilateral sternocleidomastoid muscles, about three centimeters long.

"Gauze. ”

As soon as Meng Xianyang's voice started, Yi Sheng clamped the gauze to stop the blood that had just ooped, and the two worked together, and soon cut the patient's platysma and anterior cervical fascia, and Meng Xianyang pulled the pectoral mastoid muscle outward, exposing muscles such as the sternohyoid muscle and sternal thyroid muscle.

Meng Xianyang paused, raised his head and said, "Next, for the treatment of the sternohyoid muscle and sternal thyroid muscle, sneak separation should be carried out. ”

"Stealth separation?" Yi Sheng raised his head, for now, there were two separation methods he had mastered: sharp separation and blunt separation.

"As it stands, there is no clear medical definition of stealth dissociation, or rather a name that is used to distinguish blunt dissociation. Meng Xianyang started his teaching in front of the live broadcast, "We know that when we use surgical scissors or scalpels and similar sharp tools to separate tissues, we call this method sharp separation, and when we use tweezers or glass minute needles to separate tissues, we will collectively call it blunt separation, and sneak separation can also be said to be a kind of blunt separation, in short, the way of stealth separation is tearing." ”

"You can now see that there are two pieces of musculature underneath the sternocleidomastoid muscle, the sternohyoid muscle and the sternal thyroid muscle, and it would be difficult to expose the carotid sheath without being able to separate them. Meng Xianyang said as he gently tore off the fascia on the sternohyoid muscle and sternal thyroid muscle with his hands, then raised his head and said: " If the force is too light, it will cause insufficient detachment of muscles and fascia and affect the surgical process, just like when you peel an orange, although the orange peel has been peeled, there will still be a thick layer of protective tissue on the surface of the pulp, which will affect the taste if you eat it, and if the force is too heavy, it will cause the flesh inside the orange to be damaged, and your hands will be full of orange juice, understand?

Yi Sheng nodded thoughtfully, watching Meng Xianyang separate the sternohyoid muscle and sternal thyroid muscle little by little, and then pulled inward to expose the carotid sheath.

"Tissue scissors. ”

After Meng Xianyang exposed the carotid sheath, he motioned to Hao Zhe to fully expose the field of vision of the carotid artery sheath with a retractor, and then he took the tissue scissors handed over by Su Jin to open the inside of the carotid artery sheath and remove part of the carotid sheath, so that the common carotid artery and its internal jugular vein appeared in everyone's field of vision.

After doing all this, Meng Xianyang took half a step back and motioned for Yi Sheng to come to the position of the chief surgeon and continue the follow-up operation.

In the venue, there was silence.

Everyone's eyes were on the display, although some of them sincerely hoped that Yi Sheng could complete the separation of the common carotid artery and the internal jugular vein, while some people also wanted to see Yi Sheng look foreign.

When Yi Sheng came to the main surgical position, he didn't do it immediately, but closed his eyes and took a few deep breaths, which was completely captured by the camera in the operating room.

"Glass minute hand. ”

After Su Jin moved the microscope, Yi Sheng opened his eyes, nodded at Su Jin, and stretched out his hand to take the glass minute hand and began his first common carotid artery separation.

Although the vascular nerve separation is not as difficult as the vascular nerve separation on the brainstem, there is an extremely important nerve in this area, the vagus nerve.

This vagus nerve is an extension of the brainstem vagus nerve, which runs parallel to the glossopharyngeal nerve and passes through the jugular foramen to exit the cranial cavity and supply all the muscles of the pharynx, larynx, and soft palate except the soft palatine muscle and the stylopharyngeal muscle.

"It's not bad, it's stable. Through the display screen, Feng Jizong, who was sitting next to Wei Xiang, praised Yi Sheng.

The word "stable" doesn't sound like a compliment, but in the hearts of Xiangen and Kang Zhenye, all the people with surgical qualifications in the entire International Medical University can be praised by Feng Jizong as "stable", but there are only a few hands.

The knife is not better than chopping meat, not paying attention to the big opening and closing, simply and neatly, the pursuit of the knife is cautious, is careful. In this world, no one dares to claim that they can guarantee that their hands do not tremble when they operate on the operation, and not shaking is a limit, and doctors can only approach infinitely without shaking, but they can never reach without shaking.

"Academician Feng, do you think I can carry out a brainstem tumor medical team in Nanyao?" Wei Xiang turned around and asked after hearing Feng Jizong's praise.

"Nanyao is a small place after all, and I have not seen more different types of brainstem tumors, and it is a bit naïve to set up a brainstem tumor center based on a successful surgical case. Feng Jizong shook his head and said, "I know that you want to rely on Shang Ai's theoretical research and Yi Sheng's young man's technique to open up a new situation in tumor treatment in Nanyao, and you are a little too anxious." ”

"Didn't I go up as soon as I saw a successful case!" Wei Xiang said with some embarrassment.

Just as he was about to continue to talk to Feng Jizong about the Nanyao brainstem tumor medical team, Feng Jizong suddenly stretched out his hand and motioned to Wei Xiang not to speak.

"The most critical part, here!"
