Back in the ward, Su Yun stood beside the patient and stared at the ECG monitor.

“How is it?”

“It’s not optimistic,” “Iabb can’t give the heart enough rest,” Su Yun said.

Zhao Yunlong placed the signed form into the medical record folder. Su Yun glanced at it and heaved a sigh of relief.

“Director Lin will be here soon. Boss, what are you going to do?” Su Yun asked.

“I’m just thinking about it. ” Zheng Ren did not answer Su Yun’s question directly. Instead, he inserted the patient’s MRI scan into the MRI scanner.

Moksha was a cerebrovascular disease with an unknown cause. It was characterized by slow and progressive narrowing or blockage at the end of the internal cerebral artery, the anterior cerebral artery, and the beginning of the middle cerebral artery. It was followed by an abnormal vascular network in the skull.

Since the abnormal vascular network of the skull looked like “smoke” on a cerebral angiography, it was called “mochizarism.”

The MRI scan clearly showed the pathological changes of the blood vessels in the patient’s brain. Old cerebral infarction and localized brain atrophy were most obvious at the bottom of the frontal lobe and the temporal lobe. The abnormal vascular network at the bottom of the skull was in a honeycomb shape or mesh low – Signal vascular image due to the space – time flow effect.

It was a more obvious case of smoke syndrome. Zheng Ren looked at the proliferated blood vessels that looked like the smoke exhaled after smoking and was a little worried.

‘Forget it. No matter what the patient’s family chooses, I’ll just go to the system’s operating theater and try it out.’

Although the chances of saving the patient were not high, Zheng Ren did not want to give up as long as there was a glimmer of hope.

If the patient could be saved in the system’s operating theater, Zheng Ren would like to try it even if it was a huge risk.

The big pig trotter was simply too hateful. Why didn’t he issue a mission when he was so seriously ill?

Out of habit, Zheng Ren placed his left hand under his right armpit and supported his cheek with his right hand as he looked at the patient’s MRI scan.

After making his decision, he entered the system space.

When he clicked to purchase the surgery training time, Zheng Ren hesitated slightly.

If the patient’s family members refused to agree to the surgery, the surgery training time that he bought would be wasted. Most importantly, this was not a general surgery, but a neurosurgery operation that he had never done before!

At the very least, he would have to “waste” a master alchemist skill book.

He had completed a quest a while ago, and the reward he had accumulated was three master level skill books. At that time, Zheng Ren had thought that he would be using it for a long time, but he did not expect to use the last one so soon.

He was about to go to Europe and face the ancient and mysterious vampire family …

However, if the patient’s family members agreed, but he could not solve this problem with surgery, what could he do?

After hesitating for less than a second, Zheng Ren made a judgment.

He bought the surgery training time and used the last master level skill book.

Neurosurgery was the most precise surgery among all other surgeries.

When Zheng Ren was in school, he had heard from his teacher that in the past, when the conditions were not good, the drainage strip would be placed after the drilling. When the drainage strip was not smooth, it was generally used to apply negative pressure to discharge the redundant drainage.

However, this negative pressure might cause a few milliliters of brain tissue to be sucked out.

As a result, due to the loss of these brain tissues, the patient would suffer from symptoms such as being unable to speak, having hemiplegia, and walking powerlessness after the surgery.

Therefore, Zheng Ren had been avoiding neurosurgery. To him, this was a very difficult surgery.

However, he had no other choice today. He had to give it a try no matter what.

‘After all, it’s a master level skill. There shouldn’t be a problem,’ Zheng Ren thought.

In 1967, yasangel was the first to successfully anastomose the superficial temporal artery to the middle cerebral artery to treat stroke. Since then, many countries had carried out this kind of surgery.

Zheng Ren didn’t believe that his surgical skills couldn’t compare to the surgical standards of the 1960s and 1970s.

After entering the system’s operating room, Zheng Ren saw the experimental lying on the operating table.

He was not in a hurry to perform the surgery. Instead, he first observed the position of the experimental body. After all, it was an unfamiliar neurosurgery department, so it was necessary to be cautious.

The system used a tracheal tube in the patient’s body while he was in a reclining position. At the same time, the system gave the patient general anesthesia via intravenous medication. The system also pierced the radial artery and connected it to monitor the wounded artery pressure. This was so that the dynamic changes of blood pressure during the operation could be observed in time, and it would provide a reliable basis for controlling and adjusting blood pressure.

Judging from the fact that the pork trotter could monitor the arterial pressure anytime and anywhere, Zheng Ren made a judgment.

The head of the experimental was inclined to the healthy side, and a microscope was placed in the operating area.

Zheng Ren took a glance. It was Zeith! He was a little excited.

According to Su Yun’s description, Zeith’s microscope could allow him to avoid the trouble of underdeveloped vestibule nerves as much as possible.

Otherwise, every time he finished a microsurgery, it would be as uncomfortable as riding a roller coaster.

Zheng Ren hated roller coasters!

It should be done. Let’s start the surgery. At this thought, Zheng Ren noticed that the experimentals had already prepared their skins.

The skin preparation in the neurosurgery department was to shave one’s head. Experienced nurses could shave quickly and steadily. Inexperienced nurses would either leave some hair behind or cut their scalps.

Zheng Ren took a look. Big pig trotter was an experienced nurse, and her skin preparation was almost perfect.

The general neurosurgery department disinfected the area and covered it with sterile surgical dressing. Local anesthetics were injected subcutially around the incision edge. The pterosaur incision was used to cut the scalp and subcutaneous tissue and stop the bleeding with bipolar coagulation.

The blood supply to the scalp was simply too rich. Although Zheng Ren had master – Level surgical skills, he was not skilled at it because the system had pulled up the seedlings to help him. He had wasted a lot of time on this step.

After that, Zheng Ren began to separate the superficial temporal artery. He cut open the reverse top of the temporal muscle with a lone pole and covered it with saline gauze.

He used the AO dynamic system and a blade to remove the skull flap, cut open the cerebral cortex, and separated the middle cerebral artery and its branches under the microscope.

The microscope was not bad. It had a 40x magnification. Zheng Ren was very careful with every step.

However, this was his first time doing this, so he failed 12 times.

The operation had failed, and the test subject had died …

The operation had failed, and the experimentals were paralyzed …

Zheng Ren was almost numb to such notifications.

However, he had experience in microsurgeries after all. The surgical scope of the neurosurgery department was narrow, so he quickly mastered the characteristic of using the microscope as gently as possible.

During his thirteenth surgical training, Zheng Ren finally completed the steps for dissociating the liver perfectly.

After selecting a suitable receptor, the ruptured end of the superficial temporal artery was anastomosed to the middle cerebral artery. The ruptured end was sutured using a 10/0poene thread laparoscope. During the suture, a soft needle with heparin saline was used to repeatedly wash the surgical field and tube to prevent thrombosis.

After the anastomosis was completed, the operating field was washed thoroughly, the duelum was flipped, and the surgical items were counted. The inner layer of the temporal muscle was applied to the surface of the meningeal gland and fixed with the dueline near the bone border.

He replaced the bone flap, sutured the scalp with a 3/0 absorbable thread, and covered the head with gauze.

Surgery completion rate, 50%!
