Chapter 984： Dissection of the experimental body

The intelligent and humanized Zheng Ren of the big pig's hoof has experience, and this is the operation that has issued the task. So after entering the system space, Zheng Ren had no doubts, he chose to buy surgery training time.

The operating room of the system rises from the ground and the experimental body lies on the operating table.

Zheng Ren began surgery.

For Zheng Ren, who is involved in the level of interventional surgery at one level, the renal artery stent is a very simple procedure.

Puncture, superselection, renal artery and the fourth and fifth small arteries, like the road driving in the eight-row road is the same as the small road bumps that do not exist in the tropical jungle.

The selection is smooth, and the bracket is opened and opened.

Surgery is as simple as that.

However, the degree of completion of the surgery was not even achieved by 50%. The words appeared on the system panel, and the experimental body died 58 hours after surgery.

Zheng Ren was not surprised by this result.

Because the process of this operation is the same as the video of the Mayo Clinic doctor's surgery, the most basic surgery is done.

At the end of the operation, the experimental body died and Zheng Ren began to dissect.

This is what Zheng Ren really wants to do.

Renal artery structure has undergone significant variability, and stenosis occurs about 5 cm from the initial stage. Renal artery stenosis leads to an increase in blood pressure and is called renal vascular hypertension.

Because of the reduction of intrarenal perfusion pressure and renal parenchymal disease, as well as cell tumors that secrete renin, all of the para-balloon cells can release a large amount of renin, causing angiotensin II activity to increase, and the systemic small arterial wall contraction to produce hypertension.

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

But after the renal artery is dilated, why is blood pressure higher?

Zheng Ren knows that this involves areas that the existing science cannot understand. As a person with a lot of pressure in his heart, Zheng Ren is not prepared to completely solve the problem of renal hypertension.

As long as he can complete a task and get surgery training time, Zheng Ren is very satisfied.

Dissecting the renal artery, Zheng Ren found that the renal sympathetic preganglionic neuron cells from the 12th thoracic segment to the medial lateral column of the second lumbar spinal cord were normal before entering the celiac ganglia and before the aorta. No abnormalities occurred. .

However, when the aorta branches and forms the renal artery, the renal sympathetic nerve that should have been associated with the renal artery actually merges in the stenosis and the renal artery.

This is the reason!

Because of the thermal stimulation of radiofrequency ablation, local anatomical variability occurs, resulting in renal artery stenosis while the renal sympathetic nerve is also entangled with the renal artery due to the exuded material.

Under the stent, the renal artery of the narrow segment is opened, and the renal sympathetic nerve is stimulated, so that an irreversible hypertension occurs.

The neurotransmitter released after the renal sympathetic ganglia is norepinephrine, which regulates renal blood flow, glomerular filtration rate, renal tubular reabsorption, and renin release.

When the renal artery and the renal sympathetic nerve are distracted by the stent and the nerve is compressed, the physiological processes of this series have changed.

Zheng Ren looked at the experimental body on the operating table of the operating room and began to ponder.

The problem has been found, what should I do?

He did not rush to end the operation, although it has now become a scene for the forensic anatomy of the body, but Zheng Ren still does not end the process.

First, the stent was used to measure the fusion of the renal artery and the renal sympathetic nerve. It was found that no matter how the angle was changed, the renal artery could not be prevented while the stent was opened.

Zheng Ren hesitated for a moment, changed his mind, and began to prepare for solving such problems with surgical methods.

Surgery, stripping the renal artery and sympathetic nerves... As long as you think about it, one of Zheng Ren’s heads becomes two big.

The difficulty of this kind of surgery has already risen directly to the sky!

Although the general surgery skills have reached the level of masters, but Zheng Ren still has no confidence.

But since you find the idea, give it a try. The system's big pig's hoof does not give S-level surgical grading, which proves the difficulty... The difficulty is still very large, Zheng Ren sighed.

Such a difficult task, not many rewards, big pig hoof this is a downtime? Zheng Ren’s heart groaned.

At the beginning of the second operation, the lateral side of the experimental body was placed, and the abdominal aorta, renal artery and renal vein were exposed along the retroperitoneal path through the longitudinal incision of the lumbar region. The renal sympathetic nerves accompanying and fused are carefully removed near the renal artery and the renal vein under a dissecting microscope.

However, Zheng Ren found a benefit.

When anatomizing normally, avoid fascia and other nerve tissues being mistaken for kidney sympathetic nerves.

In the face of this patient, only retrograde anatomy is enough.

This can reduce many surgical procedures and shorten the training time.

Zheng Ren has already made plans. This kind of difficult surgery, there is no one hundred and eight hundred, it is estimated that he can not get it.

The process of liberation was relatively smooth at first.

However, under the microscope, a little bit of free, less than 1cm distance, the blood pressure of the experimental body suddenly increased, and then the system reminded Zheng Ren, the experimental body because of high blood pressure, causing cerebral vascular rupture, has died.

Zheng Ren took a moment.

Is this not going to work? I have been very careful, using a microscope 20 times, surgery under the microscope, it seems that I have not touched the kidney sympathetic nerves.

But the death of the experimental body is a fact, and definitely what went wrong.

Zheng Ren started surgery again.

The result is still the same.

Come again... and death.

Time and time again, the body died, the operation time of the training was fast. Zheng Ren finally hesitated after the 78th surgery failed. Although he is still sure that his choice is the right way, but the surgery has failed repeatedly, always looking for reasons.

Certainly not a problem.

He did not continue the surgery training, and he was too lazy to look at the expression of the little white fox, and directly out of the system space.

"Su Yun, have you slept?" Zheng Ren asked.

"If you don't talk, I have already started dreaming."

"More dreams are a kind of performance that is not good for rest. It is impossible to enter deep sleep, and the impact on the body is very large." Zheng Rendao.

"What is it?" Su Yun did not bicker with Zheng Ren, but asked him.

"I have seen the patient's case and the surgical procedure. I highly suspect that the renal sympathetic nerve is fused with the renal artery. After the stent is built, it stimulates the renal sympathetic nerve, which leads to malignant and intractable hypertension." Zheng Rendao.

Su Yun frowned.

Just the surgical procedure, can you see the kidney sympathetic nerve? Is this not a nonsense?

But he did not ask how Zheng Ren discovered it, because there is only one answer - the technical level is not enough.

Su Yun rarely talks about it.

"How did the nervous system get when you were doing a heart transplant?" Zheng Ren asked.
