Doctor: It's reasonable to perform surgery on yourself.

Xu Qiu dug out two medical records.

They are Luo Siling and 31 beds.

Of these two, the former uses Microvi's 6.5 mm artificial blood vessel, a mature product of the world's leading company.

The 31st bed chose to believe in Daxia, or in other words, the developer Xu Qiu, and naturally used Linhai small blood vessels.

The postoperative efficacy of the two has been closely monitored.

Judging from the current results, Luo Siling's prognosis is far behind that of bed 31...

The small blood vessel of Linhai may really be able to step on the giants of the past and become a god.

"Go and check the ward." Xu Qiu grabbed the case and rushed to the inpatient department.

…

Luo Siling, VIP ward.

Her recovery was not as good as expected.

One day after surgery, three hundred milliliters of light blood fluid appeared in the drainage tube;

One hundred and fifty ml two days after surgery;

Four days after surgery, the tube was completely extubated.

In bed 31, the drainage volume on the first day was only more than 100 milliliters, and the tube was extubated on the second night.

other aspects.

The tremors and noises in various parts of Luo Siling AVG were enhanced to a certain extent and were not stable.

This is a red flag for narrowness.

However, after two weeks of observation and intervention, everything went smoothly.

"Please cooperate and do an ultrasound." Xu Qiu said.

The nurse has already brought over the bedside ultrasound.

Luo Siling is brushing the tablet. Her condition is much better than before the operation, but she still has occasional waist and back pain.

Hearing Xu Qiu's words, she raised her head and glanced, pointed at Wang Shengde and others and said, "Okay, but they have to go out."

"That's no problem." Xu Qiu looked at the dean.

Performing a breast ultrasound on a woman is a very private matter, and the patient can request it.

"Okay, let's wait for the news..."

Wang Shengde said after leaving the ward.

Hearing that Xu Qiu was going to make rounds, Yang Chenxi, who came all the way, lamented: "It's better to be handsome. Such a delicate female patient is still polite to Xu Qiu."

The chief surgeon, Director Zheng, curled his lips and said, "Yes, Xu Qiu was ignored when I was doing her ward rounds and she often rolled her eyes. That's why Xu Qiu was able to be looked at by her."

Wang Shengde refused to be lonely: "Isn't there another 31 bed? Go and see her."

Yang Chenxi smiled proudly: "What's the 31st bed? I was discharged from the hospital in the first week after the operation."

"???"

So outrageous?

The one using McVie is still lying down!

"Is this... Professor Yang's level higher, or is our own Director Zheng not good enough?" Wang Shengde showed no mercy.

Director Zheng had a dark face.

You are really the dean of my own family.

He gritted his teeth and said: "The levels are about the same, but Linhai's small blood vessels do recover faster, and various indicators indicate a good prognosis."

Yang Chenxi nodded: "There is another reason.

Bed 31 is a single mother. She has two children at home to support, so she cannot be hospitalized with peace of mind.

On the first day after the operation, she started doing some handwork in the ward.

Therefore, after we confirmed that she initially met the discharge indicators and there was no great risk, we put her back.

Luo Siling was different, the only daughter of a wealthy family. "

Wang Shengde was silent.

This is indeed a very important factor. Ordinary people cannot spend time in the hospital just to fully recover.

Spending money is one thing, but there is no way to make money.

"Another point."

Director Zheng added: “Bed 31 is very cooperative with postoperative recovery, allowing me to walk even if I endure the pain.

Luo Siling didn't follow the doctor's advice very well, so her recovery was slower. "

Although there are many variables, the superiority of Linhai's small blood vessels is still evident.

…

At this moment, in the VIP ward.

Luo Siling took off her shirt, and a touch of crimson appeared on her face.

"Doctor, I read online that in the eyes of doctors, men and women are just a piece of flesh. Is this true?"

The little nurse is a little dissatisfied. You are usually fierce, but why are you so sweet and gentle today?

She said solemnly: "When a doctor examines someone of the opposite sex, there will always be a third person of the opposite sex present. If the doctor has any evil intentions, a layman can't see it, but we nurses are very clear-minded, so don't worry!"

Xu Qiu also patiently gave the answer: "Doctors with basic ethics only think about diseases when examining the body of the opposite sex."

I've seen too much and touched too much, and I've long since become numb.

"However, there will always be cases. Insisting on the presence of a third person for supervision can basically eliminate this problem."

Xu Qiu said and began to apply coupling agent on Luo Siling's chest.

"It's a bit cold, please bear with it."

After saying that, he pressed the ultrasound probe and stared at the screen to scan.

As expected, Luo Siling squinted her eyes due to the ice, exposed her little fangs, and said with a smile: "It doesn't matter, it doesn't matter."

The little nurse's eyes almost widened.

Damn it.

On weekdays, we change your dressing, but if you touch it casually, it hurts so much that you curse.

Why is it that when Xu Qiu comes, it's like a different person!

"Um……"

Beside the bed, Xu Qiu looked intently and showed no interest in Luo Siling, who had her upper body exposed on the hospital bed.

This blood flow signal is a good standard.

These blood vessels are so beautiful.

However, he soon frowned slightly.

He found several turbulent flows at the anastomoses of several replaced blood vessels.

Turbulence, the effect of localized shear forces, often indicates stenosis.

In addition, stenosis was seen in the prosthetic vessel segment.

There is a big difference between the stenosis of artificial blood vessels and anastomosis.

The latter is due to local shear force.

But the cause of artificial blood vessels is the deposition of cellulose and lipids on the blood vessel wall.

This is actually the inherent weakness determined by the specific anatomical structure and hemodynamics of artificial blood vessels.

Many artificial blood vessels inevitably encounter these problems.

This also leads to the fact that the primary patency rate of many patients after one year is about 50%, and the primary patency rate after two years is more than 25%.

As a giant, McCormick is naturally better in this regard, basically 10% to 20% more than its peers.

However, this is also the limit.

The turbulence and mild stenosis shown under ultrasound at present indicate that Luo Siling may face stenosis problems in two years and five years.

At that time, PTA may be required.

A minimally invasive surgery - percutaneous endovascular angioplasty.

This is a common practice for most stenosis after artificial blood vessel transplantation. Relying on repeated PTA maintenance, the blood vessels remain unobstructed and the service life is extended, which can basically guarantee normal use for more than ten years.

"What about blood flow and venous pressure?" Xu Qiu asked casually.

The nurse quickly took out the examination report and said, "The blood flow is slightly low and the venous pressure is high."

"Yes."

Both indicators indicate that the patient may have early stenosis after surgery.

Fortunately, McCormick is an old giant after all, and there will be no problem in three or four years. Even if there is stenosis, it is a "follow-up lesion" that is not serious and does not require clinical treatment.

However, the fatal risk of early stenosis is not myocardial infarction or insufficient blood supply.
