Concubine

Chapter 362 Craniotomy and Brain Removal

Yang Qiuchi also remembered the matter of asking Song Yuner to inquire about Shui Wanqi last night, and when she heard that she seemed to have some good news, he sat down at the round table, waved to Song Yuner to let her sit down and talk, and asked, "Last night? What was the result of the inquiry?"

After sitting down, Song Yuner explained in detail what she heard last night, but she didn't say anything about Shui Wanqi's attempt to seduce Yang Qiuchi.

When Yang Qiuchi heard this, he was also a little shocked. He was not interested in Shui Wanqi's affair with Zhao Xinle, the prefect of Baoning Prefecture.It's really knowing people, knowing their faces, but not their hearts.

Hearing that Zhao Xinle sent boxes of gold and silver to Shui Wanqi to please her, he was very puzzled, he is a fourth-rank magistrate, and he is not a high-ranking official, so where did he get so much money?His deputy, Tongzhi, had his head chopped off because he served as a protective umbrella for the boat gang's smuggling of salt. At that time, he didn't find out that Zhao Zhifu was involved in the boat gang's affairs. Could it be that he was also secretly involved?Otherwise, where did so much money come from?In ancient times, there was no business as lucrative as trafficking in illegal salt.

Yang Qiuchi decided to tell Yun Leng the news after he returned to Bazhou, and asked him to keep an eye on the prefect Zhao to see what was wrong.

What he has to deal with now is the case of Peng Siheng's death at the pier. Hearing Song Yun'er say that Peng Hexi also beat Peng Si with a cane, this made Yang Qiuchi even more troubled.

Peng Si's death was already very complicated. There were already Shui Wanqi and Peng Laoqi mixed up in the front, but Peng Hexi's crutch was unexpectedly added.In other words, in the past two days, Peng Si's head was hit by an inkstone, a bluestone slab and a crutch. Which one is his death?Which ones do you count?Examining the body surface alone is useless. It seems that an autopsy is necessary.

But this is not in the modern society after all. If you secretly dissect it and let others know, it is not a trivial matter. If you fail, even the emperor will not be able to protect yourself.

How to do it?Do you want to take the risk.Yang Qiuchi hesitated.This Peng Si is obviously not a good person, in order to find out who killed him, is it worth taking the risk for such a person.If you want to take this risk, how to protect yourself.

In the end, Yang Qiuchi decided to take a risk. He would not be willing to find out the truth of the case. Fortunately, the injuries this time were all concentrated on the head, so there was no need for a full-body autopsy.Moreover, anatomical wounds on the head are relatively easy to hide.

Song Yuner couldn't be told about the autopsy. After all, Song Yuner was also from the Ming Dynasty, and she probably couldn't accept the fact that someone's head was cut open.

But if you don't tell her, don't take her with you, and quietly dissect it yourself, she will inevitably become suspicious.The best way is to dismiss her.

Yang Qiuchi said: "Yun'er, go find a way to find out what part of Peng Hexi's crutch hit Peng Si, the top of the head or the back of the head. It must be accurate."

"Okay!" Song Yuner happily accepted the task and walked away.

Yang Qiuchi greeted Hong Ling and said that he was going to re-examine the corpse. If anyone came to him, he said he had gone out.

Then, Yang Qiuchi picked up the forensic evidence inspection box and hurried to the room where the corpse was kept.Close the doors and windows.

Separate the hair of the corpse first, take out the scalpel from the box, make an arc-shaped incision from the back of the right ear through the top of the skull to the back of the left ear, and then turn the scalp back and forth.

After inspection, there was subcutaneous hemorrhage on the top of the head, which was caused by Shui Wanqi's inkstone.There was also a long strip of subcutaneous hemorrhage in the right temple, Yang Qiuchi's heart moved, it seemed that it should be caused by Peng Hexi's crutches.

There were no obvious deformities or fractures on the surface of the skull.Most craniocerebral injuries will cause skull fracture damage, but the absence of skull fracture does not mean that there is no intracranial injury.

Yang Qiuchi put down the scalpel, took out a fine-toothed bone saw from the box, and made a circular saw to cut open the inner and outer plates of the skull.

After opening the cranial cavity, he cut the dura mater with a pair of scissors. As a result, the brain tissue in the dura mater rushed out from the cut gap.Obviously, Peng Si's intracranial hemorrhage led to increased intracranial pressure. Once the dura mater covering the brain tissue was cut, the brain tissue inside would of course be squeezed out under high pressure.

But where exactly is the bleeding?Yang Qiuchi observed carefully, and to his surprise, there was no hematoma at the corresponding position under the long strip of hemorrhage on the right temporal part and the brain at the back of the head.That is to say, the impact caused by Peng Hexi's crutch on the right temple and Peng Laoqi's foot on the back of the head did not cause Peng Si's intracranial hemorrhage, so neither of them was the cause of death.

Where is the intracranial hemorrhage that caused the brain tissue to rush out?

Taking a closer look, the first thing that came into Yang Qiuchi's eyes was a small hematoma under the dura mater on the top of the deceased's head. It was composed of dark red blood clots. There was no new membrane forming around the hematoma, and no blood dissolved in the hematoma. And liquefaction phenomenon, it can be sure that the hematoma is newly formed.This coincides with the time when Shui Wanqi smashed the head of the victim with an inkstone two days ago.

However, Yang Qiuchi was very surprised. This hematoma was obviously formed by acute subdural hemorrhage. Since the amount of bleeding was not large and the volume of the hematoma was relatively small, it was unlikely to cause such a high intracranial pressure, and such a small hematoma was not enough to cause Peng Si died.

Under normal circumstances, intracranial hemorrhage must reach more than [-] milliliters before it will lead to death.This hematoma was far from reaching, and the increase in intracranial pressure it caused was limited and not enough to cause the death of the deceased.

Therefore, there must be another reason for the boiling of the brain tissue of the deceased, that is to say, there must be another relatively large hematoma.

Yang Qiuchi's speculation was soon confirmed. On the side of the deceased's left cerebral hemisphere, between the dura mater and the arachnoid, he found a cyst cavity.It was a cyst larger than an egg. When it was cut open, there were about [-] ml of blood and clots inside, and the left cerebral hemisphere had been obviously crushed.

This is a thick-walled cyst formed by chronic subdural hemorrhage, which has been surrounded by a new membrane formed by a new layer of connective tissue.It is speculated that the time for cyst formation should be about one month.

After searching, a gap was found in the corresponding subdural bridging vein, which caused the subdural hemorrhage.

According to the volume of the cyst and the compressive effect on the brain tissue, it is almost certain that this is the root cause of Peng Si's death.

However, Yang Qiuchi still took out the deceased's brain very carefully and conducted a thorough examination, but found no other damage or pathological changes.

Since there were no obvious lesions in the brain of Peng Si, this chronic subdural hemorrhage should not be caused by a disease, but traumatic.

According to the examination results, it can be inferred that Peng Si suffered trauma to the left side of his head a month ago. Although the trauma did not cause his skull fracture this time, the severe shock caused the deceased's bridging vein to tear and bleed.Since the tear is small, the amount of bleeding is minimal.

This kind of chronic subdural hemorrhage is very dangerous, because the increase in intracranial pressure caused by it is very slow, and the human body can adapt to this to a certain extent through the adjustment of factors such as the volume of cerebrospinal fluid and the volume of brain parenchyma. changes in intracranial pressure.Therefore, the injured will not have obvious symptoms and can still lead a normal life.

However, if the bleeding does not stop, the intracranial pressure will slowly and continuously increase, causing brain herniation, that is, the displacement of brain tissue from the high-pressure area to the low-pressure area, resulting in compression of the brainstem, leading to central nervous system paralysis and death.

Of course, Peng Si's death did not develop according to this normal law. During the development of the injury a month ago, before reaching the critical point of qualitative change, Peng Si was hit by Shui Wanqi's inkstone on the head again, causing Another intracranial hemorrhage, but this time it was an acute subdural hemorrhage.

Although the amount of bleeding this time was not large, it would not cause the death of the deceased in a short time. However, under the condition that Peng Si's intracranial pressure was already very high, this small amount of bleeding caused the critical point to be overthrown. Breaking through, Peng Si died suddenly on the way home.

Therefore, if Peng Si's injury a month ago was done intentionally by someone, then that person should bear the primary responsibility for Peng Si's death, and Shui Wanqi should bear the secondary responsibility.

What needs to be clarified now is whether Peng Si's injury a month ago was an injury, self-injury or accident.Once this issue is clarified, the case of Peng Si's bizarre death can be declared solved.

Yang Qiuchi put Peng Si's brain back into the cranial cavity, covered the skull, returned the scalp to its original position, performed concealed sutures, and then tidied up the hair.From the outside, it is not obvious that the corpse has ever undergone a head dissection.The next step is to bury the body.

After tidying up, Yang Qiuchi opened the door and came out, went back to the room and put away the forensic evidence investigation box.After washing his hands, he sat by the window and slowly sipped a cup of top-quality Longjing brought by Hong Ling.

After sitting for a while, Song Yuner came back.When Yang Qiuchi saw her smiling face, he immediately knew that she should have gained something.

Sure enough, Song Yun'er said: "Brother, I have already found out. I asked a few house slaves, and they proved that the night before Peng Si's death, they indeed came to Peng's manor to look for Mr. Peng, and told about Mr. Peng's beating him. Peng Hexi borrowed money and said that he wanted to redeem Miss Chunhong immediately, and the two started arguing, and Peng Hexi hit Peng Si on the head with a cane, and the beating happened in the hall, and several servants saw it."

"What position did you hit? Is it this position?" Yang Qiuchi smiled and pointed to his right temporal region.

Song Yuner's eyes widened: "How did you know? Did you follow me? Or did you investigate and deliberately make fun of me?"

"How dare I." Yang Qiuchi smiled, "I guessed wildly."

"Then how did you guess so accurately?"

"I'm a fortune teller!" Yang Qiuchi smiled and patted his chest.
