Zheng Ren has seen some medical records before. Because of Mayo's concealment, he did not see stent surgery and removal surgery for renal artery stenosis.

But in the email communication, the Mayo Clinic research team also admitted this, but only sent the surgical procedure of the stent surgery, while the removal process was missing from the patient's condition.

This is the first time Zheng Ren has seen this section.

The surgery removes the stent with renal artery stenosis. There is nothing good about the entire operation. Zheng Ren mainly looks at the change in the patient's physical condition after removing the stent.

After removing the stent, the patient developed a state of unstable blood pressure. Because of the need to avoid emotional fluctuations, he adopted calming state and ventilator-assisted breathing.

All kinds of rescue drugs were basically used one by one. The blood pressure booster and antihypertensive drugs were used in turn, and the patient's condition was restored to the preoperative level after 5 days.

However, the blood pressure before the operation was very high. After so much trouble, I returned to my preoperative state. The operation could be said to have failed.

This is also the reason why the research team is so secretive about this, Zheng Ren speculated.

"Boss, I don't think there is any problem with this pile of brackets." Professor Rudolf Wagner said.

"Well, I guess this should be because of radiofrequency ablation that causes abnormal physiological structural changes in the renal artery and renal sympathetic nerves, which will cause this situation." Zheng Ren said: "When going down the stent and pressing the renal sympathetic nerves for a long time, there will definitely be problems."

The professor was stunned.

Where did this fusion judgment come from? He rubbed his eyes and looked carefully at the imaging examination. He could only see fiber cords gathering, but he could not tell the fusion of the renal sympathetic nerve and renal artery.

However, Professor Rudolf Wagner was used to following Zheng Ren's diagnosis. He did not continue to speak, but followed Zheng Ren all the way.

Professor Danilo Acosta ran out to make a phone call when Zheng Ren started reading the information.

It was nine o'clock here, and he was not sure if the Chinese doctor had to undergo surgery early in the morning.

Moreover, there are some related work to do before the operation. Danilo really doesn’t like Zheng Ren. It seems that all the troubles were created by Zheng Ren and brought the same.

Zheng Ren watched the movie and had a comprehensive understanding of the condition.

Because he had done anatomy in the system operating room, Zheng Ren's understanding of the entire condition is the most comprehensive.

Others, even the world's top professor at Mayo Clinic, can only guess.

This is Zheng Ren's unique advantage.

The first percutaneous renal sympathetic nerve radiofrequency ablation surgery performed by Mayo Clinic is almost perfect, accurate and delicate as a textbook.

But this accuracy and delicacy is just the kind in the conventional sense. Zheng Ren suddenly felt aroused in his heart and entered the system space.

Click on the surgical training time, and the system operating room rose from the ground and Zheng Ren began the operation.

Zheng Ren had to undergo surgery, not surgery, but radiofrequency ablation.

Of course, it is not a normal radiofrequency ablation surgery. Zheng Ren directly treated the experimental subject as a general teacher, started dissection, and performed radiofrequency ablation surgery under direct eyes.

Radio frequency is a high-frequency vibration with a frequency of 150,000 times per second.

The human body mainly relies on the movement of ions to conduct current. Under the action of high-frequency alternating current, the direction of ions' concentration changes with the current direction in a positive and negative half cycle.

Under high-frequency oscillation, ions rub against each other and collide with other particles to produce biological thermal effects.

The earliest radiofrequency ablation was applied to patients with arrhythmia. Later, it was found that the tumor heat dissipation was poor, which made the tumor tissue temperature higher than its adjacent normal tissue. In addition, cancer cells were sensitive to high heat, and high heat could kill cancer cells, but side effects did not occur.

Therefore, radiofrequency ablation is also used as a tumor treatment, and the effect is equivalent to surgical resection.

Zheng Ren performed the third interventional surgery for Zheng Yunxia in Haicheng First Hospital, which used radiofrequency ablation.

The operation was very successful. Zheng Yunxia has not yet found any signs of recurrence of the tumor tissue after the operation, and the effect is almost the same as surgical resection.

In the surgery to treat nephrogenic hypertension by renal sympathetic nerve radiofrequency ablation, such a consequence occurred. It must be that the frequency of radiofrequency ablation is wrong. Zheng Ren guessed this.

Just give it a try.

Anyway, after performing the operation for Zou Jiahua, there is still a lot of time for surgery training.

In fact, Zheng Ren is very curious about unknown things, especially various medical unknowns, who are even more curious.

He knew that completing such a treatment may mean that the disease of tens of thousands or hundreds of thousands of patients will be treated. The key is that this "experiment" will not consume much surgical training time.

All consumed is just the experimental subject.

Under direct vision, Zheng Ren began to perform radiofrequency ablation of the starting section of the renal sympathetic nerve of the experimental subject.

The frequency of radiofrequency ablation of tumor tissue is generally around 460khz. The frequency of cardiac radiofrequency ablation is generally around 200khz-750khz depending on the patient's own condition and condition.

The frequency of Mayo Clinic is 510khz, which cannot be said to be a mistake.

Zheng Ren estimated that this was not the first patient to undergo renal radiofrequency ablation, and the frequency of the application was based on theoretical basis.

But it is this theoretical basis that has problems.

He guessed that if the operation was successful, the frequency should be smaller than 510khz.

So Zheng Ren began to do experiments, constantly changing the frequency of various radio frequency to achieve his own goals.

When the RF frequency reaches 185khz, the effect is the best.

This frequency is nearly twice as different from the frequency of the Mayo Clinic research group. Moreover, this frequency has exceeded the frequency of normal medical radio frequency and seems slightly lower.

Even so, this is a fact and the result of objective experiments.

Although this experiment is meaningless to Zheng Ren now, he always wants to know why.

Moreover, Zheng Ren only found how to safely use radiofrequency means to "cut off" the renal sympathetic nerve, but he did not know how the patient in front of him was melted by a high-frequency radiofrequency needle and how the solidified renal sympathetic nerve re-fusion with the renal artery.

If you study this carefully, you may not have enough time for one year of surgical training.

After Zheng Ren got the answer he wanted, he came out of the system operating room.

"That's it." Zheng Ren read all the medical records and then said.

"Surgery?" Su Yun asked.

"Yes." Zheng Ren said, "The surgery is likely to solve the problem, so it's better to do it."

Professor Danilo Acosta looked at Zheng Ren like an idiot. In his opinion, this kind of surgery was almost blindfolded and it was impossible to succeed.
