Zheng Ren had read some of the medical records before. Because of Mayo's concealment, he did not see the stent surgery and the removal of the renal artery stenosis.
However, in the subsequent email communication, the Mayo Clinic's research team also admitted this. However, they only sent the surgical process of the stent surgery, but the removal process and the patient's condition were missing.
This was the first time Zheng Ren had seen this.
The surgery removed the stent from the renal artery stenosis. There was nothing special about the entire surgery. Zheng Ren mainly looked at the changes in the patient's physical condition after the stent was removed.
After the stent was removed, the patient's blood pressure became unstable. In order to prevent emotional fluctuations from causing blood pressure changes, they used a calm state and a ventilator to assist with breathing.
All kinds of rescue drugs were used. Blood pressure drugs and blood pressure drugs were used in turn. Finally, after five days, the patient's condition returned to its pre-surgery level.
However, the blood pressure before the surgery was especially high. After so long, it returned to its pre-surgery state. The surgery could be said to be a failure.
This was also the reason why the research team was so secretive about it, Zheng Ren guessed.
"Boss, I don't think there's a problem with this stack of stents," Professor Rudolf Wagner said.
"Yes, I'm guessing that the radiofrequency ablation caused abnormal physiological changes in the renal arteries and renal sympathetic nerves. That's why this happened," Zheng Ren said. "Putting a stent in and pressing the renal sympathetic nerves for a long time will definitely cause problems."
The professor was stunned.
Where did this judgment of fusion come from? He rubbed his eyes and carefully looked at the imaging examination. He could only see the convergence of fibrous strips, but could not determine the fusion of the renal sympathetic nerve and the renal artery.
However, Professor Rudolf Wagner was already used to following Zheng Ren's diagnosis. He did not continue to speak and read along with Zheng Ren.
Professor Danilo Acosta ran out to make a call when Zheng Ren began to read the information.
He was not sure if the Chinese doctor was going to perform the surgery early in the morning.
Moreover, there were some related work that needed to be done before the surgery. Danilo really did not like Zheng Ren. It was as if all the trouble was caused by Zheng Ren.
Zheng Ren looked at the radiographic films and had a comprehensive understanding of the condition.
Because he had done dissection work in the operating theater, Zheng Ren's understanding of the entire condition was the most comprehensive.
Others, including the world's top professors and doctors at Mayo Clinic, could only guess.
This was Zheng Ren's unique advantage.
The percutaneous radiofrequency ablation of the renal sympathetic nerve performed by the Mayo Clinic in the beginning was almost as perfect as a textbook. It was accurate and meticulous.
However, this kind of accuracy and meticulousness was only in the conventional sense. Zheng Ren suddenly had an idea and entered the System space.
Zheng Ren selected the surgery training time and the System's operating theater rose from the ground.
Zheng Ren was going to perform surgery, not surgery, but radiofrequency ablation.
Of course, it was not a normal radiofrequency ablation. Zheng Ren directly treated the test subject as a cadaver and began to dissect it. Then, he performed the radiofrequency ablation surgery under the naked eye.
Radiofrequency is a high-frequency vibration with a frequency of up to 150,000 times per second.
The human body mainly relied on the movement of ions to conduct electric current. Under the effect of high-frequency alternating current, the direction of change in the concentration of ions would change with the direction of the electric current in a positive or negative way.
Under the high-frequency oscillation, the ions rubbed against each other and collided with other particles to produce biological heat.
Radiofrequency ablation was first applied to patients with cardiac arrhythmia. Later, it was discovered that the tumor's heat dissipation was poor, causing the temperature of the tumor tissue to be higher than that of its adjacent normal tissues. In addition, cancer cells were sensitive to high heat, so high heat could kill cancer cells without any side effects.
Therefore, radiofrequency ablation was also used to treat tumors, and the effect was equivalent to surgical resection.
Radiofrequency ablation was used in Zheng Yunxia's third interventional surgery for liver cancer in Sea City General Hospital.
The surgery was very successful. After the surgery, Zheng Yunxia had not found any signs of tumor recurrence. The effect was almost the same as surgery.
Zheng Ren guessed that the frequency of radiofrequency ablation of the renal sympathetic nerve to treat nephrogenic hypertension had to be the wrong frequency of radiofrequency ablation.
They would know once they tried.
After all, he still had a lot of time for surgical training after he finished operating on Zou Jiahua.
In fact, Zheng Ren was very curious about the unknown, especially the various unknowns in the medical field.
He knew that completing such a treatment could mean that the diseases of tens of thousands or even hundreds of thousands of patients would be cured. More importantly, this kind of "experiment" would not consume much surgical training time.
What was being consumed was only the Experimental Bodies.
Under direct observation, Zheng Ren began to perform radiofrequency ablation on the initial segment of the renal sympathetic nerve in the test subject.
The frequency of radiofrequency ablation of tumor tissue is generally 460 kHz.
Around Hz. Radiofrequency ablation of the heart. Depending on the patient's condition and condition, the frequency of radiofrequency ablation is usually 200 Hz.
Around 750 Hz.
The frequency used by Mayo Clinic was 510 Hz, which could not be said to be a mistake.
Zheng Ren estimated that this was not the first patient to undergo radiofrequency ablation of the kidney. The frequency used had a theoretical basis.
However, it was precisely this theoretical basis that had a problem.
He guessed that if the surgery was successful, the frequency should be lower than 510 Hz.
Therefore, Zheng Ren began to experiment, constantly changing the frequency of various radiofrequency to achieve his goal.
In the end, the radiofrequency frequency was the most ideal at 185 Hz.
Compared to the frequency of the Mayo Clinic research team, this frequency was nearly two times lower. Moreover, the frequency had exceeded the frequency of normal medical radiofrequency, which was slightly lower.
Even so, this was the truth. It was the result of an objective experiment.
Although this experiment was meaningless to Zheng Ren now, he still wanted to know why.
Moreover, Zheng Ren only found a safe way to use radiofrequency to "cut" the renal sympathetic nerve, but he did not know how the patient in front of him was melted by the high-frequency radiofrequency needle. How the renal sympathetic nerve solidified and fused with the renal artery.
If he continued to study this carefully, he was afraid that even a year of surgical training would not be enough.
After Zheng Ren got the answer he wanted, he came out of the System's operating theater.
"Then that's it," Zheng Ren said after reading all the medical records.
"Surgery?" Su Yun asked.
"Yes," Zheng Ren said, "there's a high probability that the surgery will solve the problem. Let's do it."
Professor Danilo Acosta looked at Zheng Ren as if he was looking at an idiot. In his opinion, this kind of surgery was almost done blindfolded. There was no possibility of success.
The young Chinese doctor in front of him would only be a scapegoat for the failure of the experiment.
