Zheng Ren had experienced the intelligence and humanization of the System. Moreover, this was a surgery that had been assigned a mission. Therefore, after entering the System space, Zheng Ren did not have any doubts and clicked on the purchase of surgical training time.
The System's operating theater rose from the ground and the simulation mannequin lay on the operating table.
Zheng Ren began the surgery.
For Zheng Ren, who was at the peak of interventional surgery, the renal artery stent was a very simple surgery.
Compared to the puncture, superselection, and grade four or five arterioles, the renal artery was like driving on an eight-lane highway and bumping on a non-existent road in the tropical jungle.
The superselection was successful. The stent was placed and opened.
The surgery was that simple.
However, the completion rate of the surgery did not even reach 50%. A message appeared on the System panel. The simulation mannequin died 58 hours after the surgery.
Zheng Ren was not surprised by this result.
This was because the process of the surgery was no different from the process of the Mayo Clinic doctor's surgery in the video. It was the most basic surgery.
After the surgery, the simulation mannequin died. Zheng Ren began to dissect it.
This was what Zheng Ren really wanted to do.
The structure of the renal artery had obviously changed. From the beginning, about five centimeters had narrowed. The narrowing of the renal artery led to an increase in blood pressure, which was known as renal vascular hypertension.
This was because the decrease in renal perfusion pressure, renal parenchymal disease, and renin-secreting cell tumors could all cause the juxtaglomerular cells to release a large amount of renin, causing an increase in angiotensin II activity. The walls of the small arteries in the body contracted and caused high blood pressure.
Renin and angiotensin II could also increase the secretion of aldosterone, causing sodium and water retention, increasing blood volume and causing high blood pressure.
However, after the renal artery was dilated, why did the blood pressure increase?
Zheng Ren knew that this involved an area that could not be understood by current science. As a person with a special understanding of the situation, Zheng Ren was not prepared to completely solve the problem of renal hypertension.
As long as he could complete a mission and obtain surgical training time, Zheng Ren would be very satisfied.
After dissecting the renal artery, Zheng Ren found that the renal sympathetic nerve preganglionic neuron cells from the middle lateral column of the 12th thoracic to the 2nd lumbar spinal cord were still normal before entering the celiac ganglion and located in the aorta.
However, when the aorta branched to form the renal artery, the renal sympathetic nerve, which should have accompanied the renal artery, actually fused with the renal artery at the narrowed segment.
This was the reason!
Due to the thermal stimulation of radiofrequency ablation, the local anatomical structure had changed, resulting in renal artery stenosis. At the same time, the renal sympathetic nerve had also been wrapped by the substance that oozed out and fused with the renal artery.
When the stent was inserted and the narrowed segment of the renal artery was opened, it also stimulated the renal sympathetic nerve, resulting in irreversible hypertension.
The neurotransmitter released by the postganglionic fibers of the kidney is norepinephrine, which can regulate the renal blood flow, glomerular filtration rate, renal tubular reabsorption and renin release.
When the renal artery and renal sympathetic nerve were opened by the stent and the nerves were compressed, this series of physiological processes changed.
Zheng Ren stared at the simulation mannequin on the operating table in the System's operating theater and fell into deep thought.
Now that he had found the problem, what should he do?
He was not in a hurry to end the surgery. Although it had become a forensic autopsy scene, he was not done yet.
First, he used the stent to measure the fusion location of the renal artery and the renal sympathetic nerve. He found that no matter how he changed the angle, he absolutely could not avoid compressing the renal sympathetic nerve while the stent opened the renal artery.
Zheng Ren hesitated for a moment and changed his train of thought. He began to prepare to solve this problem with surgical methods.
Surgery, stripping the renal artery and sympathetic nerve … Just thinking about it made Zheng Ren's head spin.
The difficulty of this kind of surgery had directly soared to the sky!
Although his general surgery skills had already reached the Legend level, 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 an S-rank surgery, which meant that the difficulty … was still very high. Zheng Ren sighed.
It was such a difficult mission, but the reward wasn't much. Was the System down? Zheng Ren cursed in his heart.
The second surgery began. The simulation mannequin was lying on its side. The abdominal aorta, renal artery, and renal vein were exposed through a longitudinal incision at the waist along the retroperitoneal path. Under the anatomical microscope, the renal sympathetic nerve that accompanied and fused with the renal artery and renal vein was carefully dissociated.
However, Zheng Ren found a benefit.
During normal dissection, he had to avoid the fascia and other nerve tissues being mistaken for the renal sympathetic nerve.
For this patient, he only needed to perform a reverse dissection. That would be enough.
This could reduce a lot of the surgical process and shorten the surgical training time.
Zheng Ren had already made up his mind. With such a difficult surgery, he probably would not be able to complete it without at least a thousand or eight hundred surgeries.
The process of dissociating was relatively smooth at first.
However, under the microscope, the simulation mannequin's blood pressure suddenly rose when it was less than a centimeter away. Then, the System reminded Zheng Ren that the simulation mannequin's blood pressure was too high and it had died.
Zheng Ren was stunned.
Was that not enough? He was already very careful. He used a 20x microscope. Under the microscope, he did not seem to have touched the renal sympathetic nerve.
However, the death of the simulation mannequin was a fact. Something must have gone wrong.
Zheng Ren began the surgery again.
The result was still the same.
Again and again … it died.
The simulation mannequin died again and again, and the surgical training time was quickly consumed.
After the 78th surgery failed, Zheng Ren finally hesitated. Although he was still sure that his choice was correct, he had to find the reason for the repeated failures of the surgery.
It was definitely not a problem with the technique.
He did not continue the surgical training, and he could not be bothered 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 didn't say anything, I would've started dreaming."
"Dreaming is a manifestation of poor rest. Not being able to enter deep sleep has a great impact on the body," Zheng Ren said.
"What's the matter?" Su Yun did not argue with Zheng Ren.
"I've read the patient's case and the surgical process. It's highly suspected that the renal sympathetic nerve and the renal artery are fused. After the stent is inserted, it stimulates the renal sympathetic nerve, which leads to malignant and stubborn hypertension, "Zheng Ren said.
Su Yun frowned.
It was just the surgical process, and he could see the renal sympathetic nerve? Was this not f * cking nonsense?
However, he did not ask Zheng Ren how he found out because there was only one answer — his skill level was not high enough.
Su Yun rarely asked for a snub.
"When you did the heart transplant, what did you do to the nervous system?" Zheng Ren asked.
