The System’s intelligence and humanity was something that Zheng Ren experienced.
It issued the task of surgery.
Therefore, after entering the System space, Zheng Ren did not have any doubts, so he then click on the purchase of surgical training time.

The System operating theater rose from the ground and the subject lies on the operating table.

Zheng Ren began the surgery.

For Zheng Ren, who was at the prime of the stage of interventional surgery, the renal artery stent was a very simple surgery.

Compared to the fourth and fifth grade arterioles, the puncture, the superselection, and the renal artery were the same as driving on an eight-row road and bumping on a path that did not exist in tropical jungles.

The superselection went smoothly.
The patient entered the stent and opened it.

The surgery was that simple.

However, the completion rate of the surgery was not even 50%.
The words appeared on the System panel.
Simulation mannequin died 58 hours after the experimental surgery.

Zheng Ren was not surprised by this result.

This was because the process of the surgery was exactly the same as the surgery of the Mayo Clinic doctors in the video.
They performed the most basic surgery.

After the surgery was over and the experimental subject died, Zheng Ren began to dissect.

This was what Zheng Ren really wanted to do.

The structure of the renal artery had undergone a significant change.
From the beginning, there was a narrowing of about 5 cm.
The narrowing of the renal artery led to an increase in blood pressure, which was known as renal vascular hypertension.

Because of the decrease in renal perfusion pressure and renal parenchymal disease, as well as cell tumors that secreted renin, they could release a large amount of renin from the peripheral cells, causing the activity of angiotensin II to increase.
The walls of the small arteries in the whole body would contract, resulting in high blood pressure.

Renin and angiotensin II could also increase the secretion of aldosterone, causing sodium water retention, increasing blood volume, and resulting in high blood pressure.

But after the renal arteries were dilated, why would the blood pressure be higher?

Zheng Ren knew that this involved an area that could not be understood by current science.
As a person with a strong sense of urgency, Zheng Ren was not prepared to completely solve the problem of renal-derived hypertension.

As long as he could complete one task and obtain the time for surgical training, Zheng Ren was very satisfied.

After dissecting the renal artery, Zheng Ren found that the body of the presynaptic neurons of the renal sympathetic ganglia, which were emitted from the medial lateral column of the spinal cord from the 12th thoracic segment to the 2nd lumbar segment, was normal before it entered the celiac ganglia and was located in the aorta.
There were no abnormalities.

However, when the aorta branches and formed the renal artery, the renal sympathetic nerve — which was supposed to accompany the renal artery — actually fused with the renal artery in the narrow segment.

Because of the thermal stimulation of radiofrequency ablation, it led to local anatomical changes, which resulted in the narrowing of the renal artery.
At the same time, the renal sympathetic nerve also fused with the renal artery because of the exudation of substances.

When the stent was inserted, it opened up the narrow segment of the renal artery.
At the same time, it also stimulated the renal sympathetic nerve, resulting in irreversible high blood pressure.

The neurotransmitter released by the fiber terminals after the renal sympathetic ganglia was norepinephrine.
It could regulate the renal blood flow, the glomerular filtration rate, the reabsorption of the renal tubules, and the release of renin.

When the renal artery and the renal sympathetic nerves were opened up by the stent, and the nerves were compressed, this series of physiological processes changed.

Zheng Ren looked at the experimental body on the operating theater of the System and began to ponder.

He had found the problem.
What should he do?

He was not in a hurry to end this surgery.
Although it was now a scene where a forensic doctor dissected a corpse, Zheng Ren still did not end this process.

First of all, he used a stent to measure the fusion of the renal artery and the renal sympathetic nerve.
He found that, no matter how he changed the angle, he absolutely could not open the renal artery while avoiding the compression of the renal sympathetic nerve.

Zheng Ren hesitated for a moment, changed his train of thought, and began to prepare to use surgical methods to solve this problem.

Stripping the renal artery and sympathetic nerve with surgery… Just thinking about it, Zheng Ren’s head would become two big ones.

The difficulty of this kind of surgery had already soared to the sky!

Although the general surgery skill had already reached the level of a legend, Zheng Ren still did not have much confidence.

However, since he had found a way, he would give it a try.
The System did not give him an S-grade surgery rating, which meant that the difficulty… was still very high.
Zheng Ren sighed.

Such a difficult mission did not give him many rewards.
Was the System’s server down? Zheng Ren cursed in his heart.

The second operation began.
The experimental subject lay on its side.
Through the waist, the longitudinal incision followed the retroperitoneal path to expose the abdominal aorta, renal artery, and renal vein.
Under the anatomical microscope, the renal artery and renal vein were carefully free of the accompanying and fused renal sympathetic nerves.

However, Zheng Ren found a benefit.

During normal dissection, the fascia and other nerve tissues had to be avoided from being mistaken for the renal sympathetic nerves.

In the face of this patient, it was enough to perform a retrograde dissection.

This can reduce a lot of surgical procedures and shorten the surgical training time.

Zheng Ren had made up his mind that he would not be able to take down such a difficult operation without thousands of them.

The process of dissociation was relatively smooth at the beginning.

‘Can’t I not do that? I’ve been very careful, using a 20-fold microscope for microscopic surgery, and it does not seem to touch the renal sympathetic nerve AH.’

‘However, the subject’s death was a fact.
Something must have gone wrong.’

Zheng Ren began the operation again.

Subject death after subject death, surgical training time was rapidly consumed.

After the failure of the 78th surgery, Zheng Ren finally hesitated.
Although he was still sure that the method he chose was correct, the reason for the repeated failures of the surgery had to be found.

It was definitely not a problem with the technique.

He did not continue with the surgical training, nor did he bother to look at the little white fox’s mocking expression.
He directly left the System space.

“Su Yun, are you asleep?” Zheng Ren asked.

“If you did not speak, I would have started to dream.”

“Having too many dreams is a sign of not having a good rest.
Being unable to enter a deep sleep has a great impact on the body,” Zheng Ren said.

“What’s the matter?” Su Yun did not bicker with Zheng Ren.
Instead, he stood up and asked.

“I have seen the patient’s case and the surgical process.
I highly suspect that the renal sympathetic nerve has fused with the renal artery.
After the stent was implanted, it stimulated the renal sympathetic nerve, which led to the malignant and stubborn type of hypertension,” Zheng Ren said.

It was just the course of the surgery, but he could see the renal sympathetic nerve? He was making up f*cking nonsense.

But he did not ask Zheng Ren how he found out, because the answer was only one thing: his own skill level was not good enough.

Su Yun rarely asked for trouble.

“When you do heart transplants, how did the nervous system work?” Zheng Ren asked.
