The sudden accident made Liang Xiong stunned!

Because he found that the 4F caliber catheter could not penetrate deep and reach the area where it was tied.

It's definitely not because of the brachial artery diameter!

But because the angle of blood vessels is tricky after they are malformed, it is more difficult to pass through this area according to blood vessels!

but……

Liang Xiong’s years of experience should not fail in the prediction?

How could this happen?

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

Zhao Nan, who was standing beside him, couldn't help saying, "We were also in this place at that time."

"I always feel... it's because the catheter is not in compliance, which makes me feel a resistance when pushing the catheter. It should be possible to enter according to the blood flow!"

Liang Xiong was stunned when he heard this.

His hands were still very stable, and he twitched the catheter back and forth, carefully.

In fact, catheters need to be very cautious within the blood vessels, because the most taboo thing is to damage the blood vessel wall.

Especially those who have vascular diseases and heart disease.

What is compliance?

It is the ability of the catheter to adapt to the blood vessels.

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

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

But why can't you pass?

Liang Xiong suddenly said: "It's not a problem with 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 at Liang Xiong with wide eyes.

No one spoke in the entire operating room!

Liang Xiong stared at the blood vessels with his eyes straight.

Finally, he said: "It's not a problem with the catheter, but a blood vessel!"

"The blood vessel wall is very rough, which leads to low lubrication. Moreover, when I push, I obviously feel the increase in the push and support force, which is very wrong!"

"This blood vessel may have received trauma!"

After saying that, Liang Xiong hurriedly asked, "Old man, have your arm... been injured?"

The old man couldn't help frowning and began to think seriously.

suddenly……

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

"But, it's been more than fifty years old, right? I was only thirty years old at that time, and I was repairing a house for people in Jiangxi, and then I accidentally fell into my arm!"

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

“It’s been fifty years…”

"If you don't say it, I'll forget it myself... Alas!"

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

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

Even this can be guessed!

In fact, after the blood vessels are damaged, they can indeed heal themselves.

But...it's hard to say what heals in detail!

Liang Xiong looked at the patient's blood vessels and couldn't help but sigh. This was not a congenital deformity at all.

This is...the acquired collateral cycle formation.

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

Due to the damage and compression, the brachial artery was changed!

This situation is...it's really rare.

Moreover, this old man has been in the fifty years before he discovered it.

Thinking of this, Liang Xiong was a little moved.

but……

No matter how I feel, the biggest problem now is that there is definitely no way to perform interventional surgery.

The catheter cannot pass through this tortuary blood vessel, and there is no way to send the catheter into it along the guidewire.

Because I am worried about damaging the blood vessels, the catheter used is not very controllable, and the longitudinal strength and anti-twist ability are very low!

In this way, the lower the possibility of sending the catheter in!

What to do?

Try it!

In the nervous and worried eyes of everyone around.

Liang Xiong began to try carefully again and again!

The manipulation of interventional surgery is very high.

And it’s really a good pair of hands and a grasp of blood vessels under the image data!

Liang Xiong is very proficient!

but……

The next few efforts did not achieve good results.

The operation suddenly fell into a difficult situation.

what to do?

At this moment, time had passed by minute by minute, and it was past seven o'clock.

It has been six hours since Mr. He Hui became ill.

Liang Xiong began to worry!

At this time, he was not the one who was most anxious, but the people staring at the big screen surgery in the office!

They were all panicked!

Some of the He family have already started to curse themselves nervously.

Although they couldn't understand the operation, they were obviously aware that they had encountered problems!

“It’s been six hours!”

"Can you do it? If not, please tell me earlier!"

"Yes, if something goes wrong with my father, can you... bear this responsibility?"

"Why……"

...

This group of people is really worried.

The old man’s hands are more precious than their lives!

This is the money tree of the entire old He family.

It’s enough to make some money from home every few days to make them eat and drink!

...

...

At this time, Zhao Nan was also very nervous.

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

But, what to do?

Zhao Nan couldn't help asking, "Director Liang...why... look for Academician Shou?"

Suddenly, a word woke everyone up!

yes!
