Chapter 444: Chapter 443: Eliminating a Public Menace

"Feifan, find me the real reason for this finger’s necrosis!"

Yan Feifan heard this, then glanced at the dark gray left index finger, severed at the base and sealed in a bag, that Chen Yu had handed him.

He couldn’t help but remind her, "Mrs. Yu, I’m not a forensic examiner."

"Isn’t it a bit inappropriate for me to be the one to find the cause?"

Chen Yu said in a low voice, "You have a high level of surgical skill and a detailed understanding of human anatomy. You can find the cause quickly."

"If you record it objectively and fairly, and document the evidence properly, no one will question it if this really goes to an incident review or a lawsuit."

Her gaze sharpened, and she added impatiently, "I’ll take responsibility for any problems that arise."

"Stop dawdling and get to it."

Yan Feifan obediently agreed, took the sealed bag with the severed finger, and left the director’s office.

He went to a laboratory on the third floor.

Yan Feifan first set up two recording cameras on either side, then laid out a set of surgical instruments needed for dissecting the finger.

At 1:33 PM, once everything was ready, Yan Feifan faced the camera and formally stated the current time, location, and the task he was about to perform.

Then, he picked up a scalpel and began the dissection of the severed finger.

Organ necrosis has two main causes: ischemia and infection.

From Yan Feifan’s initial visual analysis of the severed finger, he deduced the cause was ischemia.

However, to avoid letting overconfidence cause him to miss other possibilities, Yan Feifan strictly followed the procedures for a forensic dissection, proceeding meticulously step by step.

The skin of the severed finger was completely peeled away.

Yan Feifan examined it, and after finding no suspicious issues, placed it on a metal tray to the side.

Next was the removal of fat and muscle...

During the dissection, Yan Feifan naturally focused on the suture site of the finger’s wound.

The muscle healing at the wound showed some adhesion and misalignment, but not to a significant degree.

Although Yan Feifan wanted to shake his head at the quality of this wound treatment, an objective evaluation would be that it was just barely passable.

All the fat was removed, and most of the muscle was peeled back, clearly exposing the blood vessels and nerves.

Yan Feifan then carefully examined the vascular suture site on the healed wound. The twisted shape of the blood vessel made him frown, and anger flared up.

’That son of a bitch didn’t even try to suture it properly.’

During vascular anastomosis, after aligning the vessels, the tension on each suture must be uniform.

Otherwise, uneven tension from the sutures will gradually release torsional stress on the suture line, causing the soft blood vessel to twist and deform, which in turn affects blood circulation.

By Mrs. Yu’s standards, she wouldn’t let a student take on a surgery beyond their skill level if they weren’t qualified.

This could only mean that whoever did this was careless when treating the chef’s finger injury.

However, this degree of vascular torsion would only somewhat impede blood circulation, not enough to cause necrosis.

The real cause had yet to be found...

When Yan Feifan had completely dissected a slender digital vein, with an average diameter of about 0.4 millimeters, he finally found the culprit behind the finger’s necrosis.

The vein was blocked by a small bulge.

He cut open the small bulge on the vein and found a tiny black particle.

After rinsing it with saline, Yan Feifan discovered it was a tiny, irregular, grayish-white bone fragment.

He placed the small particle under a microscope for observation.

Judging by the internal structure of the tiny bone chip, Yan Feifan determined it was not human bone.

As for whether it was pig, chicken, or fish bone, that would require further testing.

However, that test was no longer necessary.

Yan Feifan had found the cause of the patient’s finger necrosis, completed the relevant evidence documentation, and cleaned up the operating table.

Afterward, he found Mrs. Yu and gave her a detailed report.

Chen Yu held the sealed bag up to her eyes, carefully examining the tiny bone fragment that you had to squint to see clearly.

"So you’re saying there was a problem during debridement and irrigation, which allowed this unknown bone fragment to enter a blood vessel in the finger?"

Yan Feifan nodded. "This blockage, found in the vein, most likely originated from a problem during the irrigation."

Chen Yu was silent for a moment, then asked, "And your assessment of the quality of the wound treatment?"

Yan Feifan said bluntly, "The level of treatment is barely passing. The attitude and care demonstrated are failing."

Chen Yu let out a soft sigh. "I see."

She continued, "Feifan, that’s all for this afternoon. You can go take care of your own things."

Yan Feifan said, "Oh," and turned to leave, but after a couple of steps, he turned back.

"Mrs. Yu, the twins who need the leg and hand transplant will arrive at the Affiliated Hospital tomorrow evening..."

Chen Yu cut him off directly, "I’m also very interested in a transplant surgery like that."

"Give me a day’s notice, and I’ll make the arrangements..."

Around 4:00 PM, after leaving the trauma surgery department, Yan Feifan went directly to the director’s office of the plastic surgery center.

Seeing that Mr. Wang wasn’t there, Yan Feifan decided to use it as his temporary office.

He needed to reconsider his upcoming schedule.

The twin sisters’ leg and hand transplant, along with the facial burn reconstruction, was a major surgery requiring a large, collaborative team.

It would require at least one day to optimize the surgical plan and another day for the surgery itself.

The surgery needed to be performed as soon as possible, provided the younger sister was physically able.

After all, her twin sister was already brain-dead, her bodily functions sustained entirely by medical equipment.

Leaving aside the issue of cost, the longer they waited, the more likely it was that complications would arise in the body.

Just then, Yan Feifan suddenly realized he had overlooked something.

He quickly took out his phone and called He Junxing.

"Mr. Ho, I need you to contact the twins’ family and the charitable foundation that’s helping them."

"Ask if they’re willing to do an organ donation. It’s a great act of charity that could save ten to twenty people."

Yan Feifan added a warning, "With something like this, you must respect their decision. You can try to persuade them, but you absolutely cannot force or coerce them with incentives."

"Understand?"

After getting an affirmative reply from He Junxing, Yan Feifan hung up the phone.

He hadn’t even put his phone down when it rang again.

It was a call from his younger uncle.

"Feifan, when are you going to take a look at Rong Bin?"

Yan Feifan rolled his eyes and said, "Uncle, I’m really busy right now. I won’t have any free time in the near future."

"We can talk about it after you get back to Binhai."

"He’s been catatonic for a year or two already; waiting another ten-plus days won’t make a difference."

After a pause, Yan Feifan changed his tone to a warning, "Uncle, don’t say I didn’t warn you."

"If you go back to your old bad habits, my sister and I will really disown you as our uncle. We’ll cut all family ties."

"I know, I know!"

His uncle promised over the phone, "Feifan, don’t worry. I’ve already turned over a new leaf."

"Your sister... she’s a ruthless one. I’m honestly scared she’ll do something drastic."

"Feifan, there’s something else I wanted to talk to you about."

"Uncle, just say it!" Yan Feifan urged.

"Those guys who set us up back then... you know what they say, a leopard can’t change its spots. They probably haven’t stopped their dirty work, right?"

"Feifan, you’re a big shot now. You have connections at the Public Security Bureau branch. How about you ask them to look into it?"

"You’d be getting revenge for your uncle and getting rid of a public menace at the same time!"
