In the conference room of the Sixth Hospital of the Demon City, a tense case discussion is underway.

Hong Zhigang presided over the meeting, and orthopedics, neurosurgery, oncology surgery, medical oncology, cardiovascular medicine, respiratory medicine and other departments also attended.

Dean Chen and Director Peng of the Medical Department of the Magic Six attended the meeting as observers.

Among the many experts, there are also several experts who have traveled from the United States for consultation.

The case under discussion is none other than Academician Feng Tiancheng, Professor Feng is a domestic orthopedic champion, whether it is the Sixth Magic Hospital or Hong Zhigang personally, he will do whatever it takes to treat his disease.

Hong Zhigang invited Professor Johanneson from the Department of Neurosurgery at the Mayo Clinic, Professor Griffin from the Anderson Cancer Center, and Professor Woodhead from the Twin Cities Spine Center from the United States.

The team that treated Professor Feng's illness is undoubtedly the dream team of today's world.

Prof. Fung's upper spinal cord and bulbar tumours have invaded the respiratory and circulatory centres, causing slowing of breathing and heartbeat.

At one time, due to respiratory depression and arrhythmia, blood oxygen saturation could not rise, acid-base and electrolyte disorders, and he was sent to the ICU for rescue.

After resuscitation, he improved after a period of ventilator-assisted breathing, and was extubated and weaned a week ago.

At present, under the condition of oxygen inhalation, the oxygen saturation is maintained at more than 95%, and the acid-base and electrolyte balance are corrected, but the heart rate and respiratory rate have been very slow and have not returned to normal, and the heart rate is maintained at 50 minutes and the breath is 16 minutes.

If the heart rate drops again, I am afraid that a pacemaker will need to be implanted, and if breathing is suppressed again, another endotracheal intubation and ventilator assistance will be required.

"The tumor is rich in blood vessels, originating from the upper cervical medulla, passing through the base of the skull in an aggressive growth mode, and entering the medulla oblongata, the tumor has been mixed with the parenchymal tissue of the respiratory circulation center, and during the process of resection, the respiratory circulation center will definitely be damaged."

"This is equivalent to peeling off the yolk in the egg, provided that the egg white cannot be damaged, but the yolk and the egg white of this egg have been mixed together and penetrated into each other, who can completely peel out the egg yolk without damaging the egg white?"

"Breathing and heartbeat begin to slow down, and within a few months, it slowly tends to stop, and if it hits the bottom line again or causes a foramen magnum hernia, the patient dies at any time---"

Professor Johannathan from the Department of Neurosurgery at the Mayo Clinic spoke in American English.

He said it was a pity that the Mayo Clinic's neurosurgery was ranked No. 1 in the U.S., and Johanneson was the best neurosurgeon in the world.

Professor Griffin of Anderson Cancer Center, bald, obese, with a circle of sparse golden hair curly around his head, he loosened his tie: "This kind of chordoma, before the pathological examination, we will call it chordoma for the time being, the current success rate of surgery is less than one percent, in other words, that is, the success rate is close to zero, and the very few successful cases are that there is no obvious mixture between the tumor and the respiratory and circulatory center, Professor Feng's situation, even if the laser scalpel is used, the injury cannot be avoided, and no one can challenge this surgery, It is currently a forbidden place for surgery. ”

Woodhead, who was taller and thinner at the Spine Center of the Twin Cities, looked in good spirits, and he pointed to the anatomical model on the screen and explained:

"Exposure is also a problem, the occipital craniotomy of neurosurgery is docked with the posterior exposure of the cervical vertebrae, the occipital bone opens to expose the medulla, the door opens on the back of the upper cervical vertebrae to expose the upper cervical medulla, and then the upper cervical cord and the medulla oblongata are dissected, either they are not removed, the excision is an injury, and the gangsters and hostages are mixed, so that I can't shoot."

"Hong, I suggest, give up the operation, maintain the status quo, and let it be, and the patient is old, after a rescue, this state cannot withstand the blow of surgery at present, not to mention that the success rate of this operation is negligible, so the operation is meaningless, and it can only accelerate death---"

Professor Johanneson spread his hands and said that everyone had done their best, but there was nothing they could do.

Dean Chen's eyes fell on Hong Zhigang, and the medical records in Hong Zhigang's hand were rummaging through, feeling very unwilling, was there really no way?

He knew that there was no need for a person who was almost eighty years old to fight for this hopeless operation, but he didn't want to watch his teacher leave like this, he had to do something.

These world's top bigwigs are helpless, which means that they can really only watch the teacher leave, and it is foreseeable that if the tumor is not removed, or persist for two or three months, or misfortune will happen tomorrow.

Hong Zhigang's heart was like fire at this time, and he was in pain, and the teacher was kind to him, but he had nothing to do.

Although the teacher is almost 80 years old, judging from other physiological indicators, if it weren't for this tumor, it would not be a problem to live for a few more years.

"Hong, when you sent me the patient information, I used virtual reality technology to simulate the operation, and there was no success for the time being, and I failed with respiratory and heartbeat arrest in the middle." Professor Johanneson spoke again.

The virtual reality he mentioned is currently the most advanced technology in the world, which can simulate the anatomy and physiology of organs.

Then, using virtual tactile technology, surgeons can operate on virtual organs, cut a certain part, it will bleed, injure an important part, it simulates physiological interference, relatively close to real surgery.

This is Professor Johannathan's magic weapon, and he will use this system to simulate ultra-high-risk surgeries.

However, no matter how realistic it is, this technology cannot simulate the truly complex human body, and can only do simple simulations of physiology and anatomy.

"Professor Hong?" Wen Rentao next to him saw Hong Zhigang's strange appearance.

A tear slowly seeped out of the corner of Hong Zhigang's eyes, and he quickly took out a tissue and wiped it: "It's okay, let's think of a way, it's impossible to have no way." ”

How many difficult surgeries, in his hands, turned the danger into a disaster, and finally succeeded.

The atmosphere of the entire venue was gloomy, and today I have to recall that I mainly listened to the opinions of American experts, who have discussed them many times.

"Palliative care with radiation is recommended, which may prolong survival, and if needed, I can help arrange, recommend the EDGE non-invasive surgical system, and I can help contact the Henry Ford Hospital Oncology Center in the United States." Professor Griffin breaks the dullness.

The EDGE Non-Invasive Surgical System, the world's most advanced radiation oncology treatment device.

"Thank you, your comments are invaluable, let's think about it again." Hong Zhigang stood up and bowed to everyone.

Several colleagues flew across the Pacific Ocean to come to the consultation and helped, but the illness was too serious, and the doctor was a man, not a god.

The consultation meeting ended, and several American professors were shown around the hospital.

"There's a call from the ICU, Elder Feng wants to see you." Wen Rentao whispered to Hong Zhigang.

"Well, I'll go over for a while, you accompany everyone, are the results of the 16-bed MRI coming out?" Hong Zhigang asked.

"It's out." Wen Rentao knows the patients in the department well.

Hong Zhigang gave Wen Rentao the task of accompanying the American professor, and he was very satisfied with the student's technical strength and communication skills.

Hong Zhigang hurried to the ICU, although the teacher was conscious, but the heartbeat and respiratory rate were still relatively slow, this is the interference of the tumor on the respiratory circulation center, I don't know where this lifeline is, once the lifeline is crossed, the teacher will leave.

Hong Zhigang wore an isolation gown, a hat and a mask, changed into shoe covers, and entered the ICU.

Seeing Hong Zhigang rushing over, Professor Feng stretched out his hand, and his voice was quite sober: "Zhigang!" ”

"Teacher, I'm here, just after attending the consultation, Professor Johanneson of the Department of Neurosurgery at the Mayo Clinic, Griffin from Anderson Cancer Center, and Woodhead from the Twin Cities Spine Center discussed the surgical plan together, and they are experienced in this area, and the success rate of the operation is very high." Hong Zhigang helped the teacher sort out the oxygen catheter and held the teacher's hand.

Professor Feng smiled slightly: "Zhigang, you have a heart, we are doctors, we must seek truth from facts, my case, from the current reports, the success rate of the operation is less than one percent, my complex upper cervical spinal cord and medulla bulbar tumor, our hospital has no precedent, you don't have to hesitate, arrange surgery for me, you will be the main surgeon, if it fails, conduct an anatomical study on me after surgery, thoroughly figure out the pathological characteristics and surgical methods of this tumor, and raise the surgical level of our upper cervical skull base complex tumor to a higher level, The progress of medicine is full of risks and ups and downs, and even if I don't have this disease, how many years will I live?"

"Teacher, you have a good rest, the EDGE non-invasive surgery system at the Henry Ford Hospital Oncology Center in the United States is also more suitable for your situation, and I am in contact." Hong Zhigang comforted the teacher.

"In the final analysis, EDGE is a radiation treatment, and the accuracy is only 0.2 mm, which cannot guarantee that the respiratory circulation center will not be damaged, and if the laser knife is used in surgery, the current laser knife accuracy has been 0.1mm, or even lower, there is a glimmer of hope." Professor Feng is currently in his right mind.

"Did the 16-bed MRI come out?" Professor Feng suddenly remembered the purpose of calling Hong Zhigang over.

"It's out!"

"Show it to me."

Professor Feng coughed a few times and supported himself to get up, but Hong Zhigang immediately held him down: "Teacher, don't move, I'll show you." ”

Hong Zhigang waved his hand through the glass door, and the doctor in the ICU immediately came in, and Hong Zhigang said, "Please bring a tablet." ”

The doctor sent a tablet, and Hong Zhigang entered the hospital system, called up the patient's MRI, and then shook the teacher's bed slightly higher.

"I'm not used to seeing this thing," complained Professor Feng, who was used to watching film on the reading light, but now living in the ICU ward, he had to settle down.

"This is likely to be parenchymal hemangioblastoma, be careful when resecting, these blood vessels are very thick, ligate the blood vessels while removing, this is the risk area of blood circulation of the thoracic spinal cord, pay attention to protect the blood circulation of the thoracic spinal cord, especially this blood vessel should be very careful, do not damage, once damaged, the spinal cord will be ischemia, causing paralysis after surgery, remember to remember! Is the surgery scheduled?" Professor Feng told me a thousand times.

"It's lined up, Rentao is the main knife." Hong Zhigang helped the teacher press his legs and do ankle pump exercises, and lying on the bed for a long time is easy to cause venous thrombosis in the lower limbs.

"Rentao, this kid is good, but after all, young people are inexperienced, you have to go to the stage to be his assistant, this kind of operation is easy to fall into a trap, you must not have any carelessness." Professor Feng carefully explained to Hung Zhigang.

"He's steady, this tumor needs to be microscoped, and he is now more stable under the microscope than me, but don't worry, I'll be on stage." Hong Zhigang said with a smile.

Professor Feng put down the tablet and half-lay down to rest, which can reduce the load on the heart.

"When you're ready, I'll take you to our countryside to rest for a month, and now it's time to fish in the creek." Hong Zhigang chatted with the teacher while watching the guardianship screen.

"Oh, I'm afraid I won't be able to go, you go get busy, I'll sleep for a while."

Professor Feng squinted.
