Chapter 1784 Wait for the Old Man!

The sudden accident made Liang Xiong stunned!

Because he found that there is no way for this 4F caliber catheter to go deep and reach the area where it is tethered.

Definitely not because of the diameter of the brachial artery!

It is because the angle of the vascular malformation is tricky, and it is more difficult to follow the blood vessel to pass through this area!

but……

With so many years of experience, Liang Xiong shouldn't be able to predict failure, right?

How is this possible?

Liang Xiong couldn't help frowning, and muttered: "This angle should be able to pass!"

Zhao Nan on the side couldn't help but said: "At that time, we also had trouble getting through this place."

"I always feel... the lack of compliance of the catheter makes me feel a kind of resistance when I push the catheter. According to the blood flow, I should be able to go in!"

Liang Xiong was stunned when he heard it.

His hand was still steady, and he twitched the catheter back and forth, cautiously.

In fact, the catheter needs to be very cautious inside the blood vessel, because the most taboo is to injure the blood vessel wall.

Especially those who have vascular disease and heart disease themselves.

What is compliance?

It is the ability of the catheter to adapt along the blood vessel.

However, with the development of polymer science and technology, there are more and more materials with good compliance.

Including the catheter in Liang Xiong's hand, it is made of PET, which can be said to be one of the most flexible materials.

But why can't it pass?

Liang Xiong suddenly said: "It's not a matter of materials and catheters!"

Hearing this sentence, Zhao Nan was stunned: "That's..."

Liang Xiong insisted: "It's a blood vessel problem!"

As soon as these words came out, the surroundings suddenly became quiet, and everyone stared up at Liang Xiong with wide-eyed eyes.

In the entire operating room, no one spoke!

Liang Xiong stared straight at the blood vessels.

Finally, he said, "It's not the catheter, but the blood vessel!"

"The blood vessel walls are very rough, resulting in low lubricity. Moreover, when I push, I obviously feel the increase of the pushing force and supporting force, which is very wrong!"

"This blood vessel may have been traumatized!"

After finishing speaking, Liang Xiong quickly asked: "Old man, has your arm... been injured?"

The old man couldn't help but frowned, thinking seriously.

suddenly……

He Hui recalled: "It seems that he was indeed injured!"

"However, it has been more than 50 years, right? At that time, I was only 30 years old. I was repairing a house in Jiangxi, and then accidentally fell on my arm!"

"But people at that time were not particular about it, and it was normal to have bumps and bumps on the construction site. I was afraid that the foreman would not want me, so I told the foreman that I was fine, and then I didn't go to the doctor. I recovered by myself!"

"It's been fifty years..."

"If you don't tell me, I've already forgotten... hey!"

After hearing He Hui's words, everyone was stunned.

They looked at Shou Weixiang in shock, feeling a little emotional, maybe this is the boss!

Even this can be guessed!

In fact, after a blood vessel is damaged, it can indeed heal itself.

But... It's hard to say what kind of specific healing it will be!

Looking at the patient's blood vessels, Liang Xiong couldn't help sighing, this was not a congenital deformity at all.

This is... acquired collateral circulation formation.

After the brachial artery was injured, the injury was not serious at that time, but fortunately, the collateral circulation was established, which did not lead to ischemic necrosis.

Because of the injury and compression, the brachial artery was abruptly changed!

This kind of situation... is really too rare.

Moreover, this old man has been more than 50 years old before he found out.

Thinking of this, Liang Xiong felt a little emotional.

but……

No matter how you feel, the biggest problem now is that interventional surgery is definitely impossible.

There is no way for the catheter to pass through this tortuous blood vessel, let alone send the catheter along the guide wire.

And I am worried about damaging the blood vessels, so the catheter used is not very maneuverable, and the longitudinal strength and twist resistance are very low!

That way, the less likely you are to want to get the catheter in!

How to do it?

Try it!

In the nervous and worried eyes of everyone around.

Liang Xiong began to try again and again cautiously!

The maneuverability of interventional surgery itself is very high.

And it really depends on a pair of good hands, and the grasp of the blood vessels under the image data!

Liang Xiong is very proficient!

but……

The next few efforts did not receive good results.

The operation suddenly fell into an embarrassing situation.

what to do?

At this moment, the time has passed by one minute and one second, and it is past seven o'clock.

At this time, it has been six hours since Mr. He Hui fell ill.

Liang Xiong became anxious!

But at this moment, it wasn't him who was most anxious, but everyone in the office staring at the surgery on the big screen!

They were all panicking in their hearts!

In the He family, some people have already started to scold their mothers nervously.

Although they couldn't understand the operation, they obviously knew that there was a problem!

"It's been six hours!"

"Is it okay? No, you should say it earlier!"

"That's right, if something goes wrong with my father, can you...can you bear the responsibility?"

"Why……"

...

These people are really worried.

The old man's hands are more precious than their lifeblood!

This is the cash cow of the whole old He family.

Getting some things from home twice in three days and selling them for some money is enough for them to eat and drink!

...

...

At this time, Zhao Nan was also very nervous.

He watched the sweat dripping down Liang Xiong's head drop by drop, and understood the pressure in his heart!

But what to do?

Zhao Nan couldn't help asking: "Director Liang...how about...see Academician Shou?"

Suddenly, one sentence awakened everyone!

yes!

Looking for Academician Shou!

Mr. Shou Weixiang will definitely find a way.

Liang Xiong nodded, he had no other choice now.

"Well, okay, go call Teacher Shou!" Liang Xiong looked at a graduate student beside him and said directly.

The graduate student hurriedly got up and went out.

And Liang Xiong said to Zhao Nan: "Change the catheter!"

"Let's try again!"

When Zhao Nan heard it, he was taken aback for a moment, and then his eyes lit up: "Change the catheter!? Good idea, what to change?"

Liang Xiong took a deep breath: "Try PVC?"

As soon as these words came out, Zhao Nan's face suddenly changed!

"PVC...isn't it suitable?"

The catheter compliance of PVC material is relatively poor, and it is easy to damage blood vessels. In fact... With the development of PTA interventional technology, it is rarely used.

Moreover, using this risk itself is relatively large.

Liang Xiong also had no choice!

Zhao Nan couldn't help asking: "How about... we wait?"

Liang Xiong took a deep breath.

wait……

Can we just wait for the old man?

Why……

Everyone sighed.
