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

And Yan Ziqiang...

Looking back, the old man was already discussing the length of the foreskin with Wang Fan, and agreed to have a circumcision done in two days.

Wang Fan was naturally quite excited.

Ever since he became a suture master, he has always felt that his talent may not be in the emergency department, but in urology.

However, Director Huang of Biwai never gave him a chance, and Qin Qiyin also disliked him, insisting that every problem should fall on the head of Doctor Biwai. It was simply impossible for Wang Fan to suture him.

If Yan Ziqiang is willing to cut, he can give the other party half price for the first one.

However, Xu Qiu quickly interrupted the two of them.

For people over sixty years old, if the foreskin is simply too long, there is actually no need to remove it.

There are only three words for daily necessities: "commonly used items", and sewing them into Pikachu will not solve the age-related degenerative problem of bifurcated ends.

"Brother Xu, I just checked him. In addition to the pearly papules, his urethral opening is red. The inflammation may be serious and reoccurring. It would be better to do it..." Wang Fan is not helpless. A good doctor, of course, cannot just cut when he wants. There must be indications for surgery.

Xu Qiu put on her gloves and took a few focused glances.

Some shrinkage.

A little red and swollen.

There are also scattered ulcers.

It is indeed balanitis, and looking at the new and old lesions, it is true that it cannot be cured in one or two times.

"Then make one." Xu Qiu said.

After that, he continued to evaluate the postoperative efficacy.

Thanks to Xu Qiu's surgical skills and various bonuses that improve the success rate and reduce complications, Yan Ziqiang's recovery effect is astonishingly good.

Ordinary patients would be thankful if they could walk a hundred or ten meters while holding on to the wall.

And Yan Ziqiang can already go up and down stairs.

Last night, he went to other wards to see three other subjects. He walked around the ward for a long time with his hands behind his back, like a big brother.

"I was cut by Dr. Xu" and "I'm healed" were written all over his face.

The energy to show off was unabashed.

This made the other three people envious.

All are surgeries.

Yan Ziqiang's risks are higher and more difficult. Logically speaking, he has to lie down for ten or eight days before he can get out of bed, right?

result……

They were still relying on painkillers in the hospital bed, and Yan Ziqiang was already full and lustful, thinking about Niuniu plastic surgery.

This is why during the ward rounds this morning, the three patients stared at Xu Qiu and kept swallowing their saliva.

…

"How about FFR?"

After completing the basic test, Xu Qiu asked coldly.

Director Zheng immediately handed over the inspection results: "0.81, biu special no."

"Um."

Xu Qiu nodded lightly.

In cardiac surgery, coronary angiography is the gold standard for diagnosing coronary heart disease.

However, with the advancement of science and technology and the development of intraluminal imaging, coronary artery lesions are no longer limited to superficial surfaces, but have moved to deeper levels. Some professional directions have suddenly become clear and can 100% reproduce human coronary arteries.

For example, the 3D printing used in previous craniocerebral separation surgery is actually one of the most cutting-edge technologies.

However, there was an accident after all, and one blood vessel was not displayed - this is also a flaw due to insufficient technical capabilities at the moment.

At the heart, this high-end technology is FFR.

The full name is fractional blood flow reserve.

Coronary angiography can only give a rough estimate of the degree of stenosis of the lesion and classify it into an ABCD cup.

FFR is awesome. It can even see the impact of stenosis on distal blood flow. Now it has been widely used in critical lesions, multi-vessel lesions, tandem and diffuse lesions, ACS, left main lesions, bifurcation lesions, etc. in clinical work with complex lesions.

It is not as simple as ABCD, but more detailed upper bust, lower bust, and girth difference. It can be accurate to several decimal places, which is very precise.

If Yan Ziqiang can reach 0.81, it means that the patency of the blood vessel bridge is very optimistic and the blood flow is running very smoothly.

"An echocardiogram will be done in a few days..." Ma Qin added.

Director Zheng shook his head: "Echocardiography is no longer possible. Now we need to do two-dimensional strain."

Ma Qin is an old expert from the last century, a living fossil of Daxia Cardiac Surgery.

His clinical habits have long been established, so he is still using regular heartbeats.

However, the cardiogram, which has been criticized over the years, has been criticized for being too subjective, lacking quantitative indicators, and having low sensitivity... Now it has finally been replaced by two-dimensional strain that can calculate and reconstruct the real-time movement and deformation of myocardial tissue in real time.

Sir, times have changed!

"Yes..." Ma Qin snorted.

He is also on the front line, so he has an understanding of two-dimensional strain.

It’s just that knowledge is easy to learn, but habits cultivated over sixty years are hard to change.

"Two-dimensional strain alone is also not very accurate."

At this time, Xu Qiu spoke.

Director Zheng stretched his neck, his face full of astonishment.

He had just shown off in front of Mr. Ma and pushed him to death. In just a few seconds, he had become Qianlang?

"Why do you say that..." Director Zheng said in a not very confident voice.

Xu Qiu explained while assisting Yan Ziqiang in the rehabilitation activities of his limbs: "It's about accuracy.

Two-dimensional strain requires a clear two-dimensional image, and its inspection effect, sensitivity, tracking ability, etc. depend on the quality of the image.

But the patient has emphysema, and the accuracy of the image display will be greatly affected. "

"Oh, yes, that's right!" Director Zheng slapped his head, he almost overlooked this.

"It has to be high frame rate speckle tracking, right?" He answered hurriedly.

Like the class study committee member who likes to show off.

"Yes." Xu Qiu agreed.

At this moment, Director Zheng's face was full of smiles, as if he was 30 years younger.

...

After checking the room, Xu Qiu was almost off work.

Suddenly there was no pressure to develop small-caliber blood vessels, and he was a little uncomfortable for a while.

But he was not relaxed.

Now that Linhai's small blood vessels are on the right track, the institute only needs to make small improvements and improvements, and Xu Qiu focuses on the large-scale production of products and the teaching of surgery.

From the laboratory to the factory, from the manufacture of one by one to the mass production of tens of thousands, there is a huge back groove that is not easy to cross.

And lowering the threshold of coronary small-caliber artificial blood vessel transplantation so that more hospitals can carry out this operation is also a big project.

All these need Xu Qiu to think about.

Fortunately, he has both the ability to attract people and cheat.

Commercialization is supervised by Yang Chenxi and others.

As for teaching - continue to improve this original surgery, and after it reaches perfection, the teaching method can be unlocked.

This is quite in line with Xu Qiu's wishes.

After all, no matter how strong Xu Qiu's medical skills are, he is just one person.

One operation can only save one person.

But if he can try to reduce the difficulty of some high-tech surgeries, so that more ordinary doctors can also have the ability to perform difficult operations, more patients will benefit.

However, Xu Qiu is still a few weeks or even months away from improving to perfection.

It's too early to talk about this.

"I have to go home and take a look."

After get off work, Xu Qiu looked at the text messages on his mobile phone and said.
