Doctor: start with the heart

Chapter 43 Super Difficult Stitching

Seeing Wang Ming stop suddenly, Zhao Xu took a closer look and immediately understood.

Because, he saw that the aortic valve ring that had been separated had some severe calcification.

"How could there be such severe calcification? How old is he?"

Sun Chang naturally also discovered this question, and asked very puzzled.

Atherosclerosis and calcification of the vascular valve ring, this is a situation that occurs when the blood vessels lose elasticity and toughness due to excessive accumulation of blood lipids in elderly people.

This Sun Lei has just passed away, how could there be such a degree of calcification? !
"Maybe it's because of some kind of special eating habits, taking in too much calcium."

Zhao Xu thought for a while and said.

"It's very possible that the patient was originally an athlete and was growing up. For the sake of physical development, it is also very possible that he took in too much calcium."

Wang Ming nodded and agreed with Zhao Xu's judgment.

However, all three of them were lost in thought at this time, and the situation is a bit tricky now.

Originally, the aorta was the largest pathway for blood circulation, but now that there is such a degree of calcification, the artificial blood vessel needs to be replaced in the future. In this case, the suture at the joint will become particularly difficult.

If the method is not appropriate, even after the replacement of artificial blood vessels, the seams of the blood vessels will not be able to withstand the huge pressure of blood circulation.

Once it is broken away, the artery will rupture immediately, and even the gods will be hard to save.

Therefore, for the current situation, the general suture method is absolutely unworkable!

While Wang Ming and Sun Chang were still silent, Zhao Xu suddenly had a flash of inspiration and said, "Director, can we use the composite multi-layer stitching method?"

"Composite multi-layer stitching method?"

Wang Ming was a little surprised when he heard Zhao Xu's words, because this suture method is usually used for peritoneal sutures.

This suture method has a very good biomechanical structure. If the suture is good, it can resist very large tension and stress. However, blood vessels are different from peritoneum.

The thickness of the peritoneum is far greater than that of the blood vessels, so it can be sutured in a layered and superimposed manner.

As for blood vessels, even the aorta is the largest blood vessel in the human body. Among the intima, media, and adventitia, the thickest media is only about 500 microns (0.5 mm).

To put it simply, the general diameter of hair is about 100 microns, and the thickness of the intima of the aorta is about 100 microns.

It is conceivable how difficult it is to do multiple layers of composite suture on the blood vessel wall as thick as hair.

"The difficulty is too high, it is very difficult to succeed!"

Sun Chang murmured.

show the classroom.

"Compound what? What is this?"

Seeing Wang Ming stop suddenly, with a serious face, Sister Yang naturally knew that Wang Ming had encountered a problem, but the stitching was too professional, so it was difficult for the layman Sister Yang to understand.

"Composite multi-layer suture method is a very difficult suture method in clinical operations. It is usually used on the peritoneum. I didn't expect that Dr. Zhao would use this suture method on blood vessels. It is really bold!"

Su Xiao explained, she looked at Zhao Xu on the screen with admiration, she would not have such a bold idea.

"Is it difficult?"

Sister Yang said with a puzzled look.

"Ever seen sewing clothes?"

Su Xiao asked back.

"Have you seen it? What's the matter?"

Sister Yang asked suspiciously.

"Now Dr. Zhao proposed that the multi-layer composite suture on the blood vessel is equivalent to dividing the blood vessel into many thin layers like hair, and then suturing in layers."

Su Xiao explained that this kind of difficulty simply surpassed the sky.

"The hair is so thin? It has to be divided into many layers?!"

Sister Yang had a dazed expression on her face, and she felt dizzy just thinking about it for a while.

Can this kind of operation be achieved by humans?

This was the only thought Sister Yang had at this time.

operating room.

"Director, there is no other way now, we only have one chance to suture, if it fails, there is no second chance."

Zhao Xu said slowly.

There is only one chance to suture the artificial blood vessel and the original blood vessel. Once the suture fails, the consequences are unimaginable.

But now the arterial wall is severely calcified. If it is a normal suture, it will not be able to withstand the pressure of the heart pumping blood.

Once the suture interface is not solid and cannot withstand the pressure of blood circulation, the blood vessels will explode like a water pipe that is frozen and cracked in winter.

At that time, it will really be hopeless, and it will be impossible for the gods to save!

"Let me think."

Wang Ming fell into deep thought when he heard what Zhao Xu said.

Time passed minute by minute, this short moment was extremely long for the people in the operating room.

After a while, Wang Ming suddenly raised his head, looked at Zhao Xu and said slowly, "Xiao Zhao, are you sure? If I leave this suture to you?"

what?
Leave it to Zhao Xu!

Hearing Wang Ming's words, the people in the operating room, as well as the doctors watching the real-time broadcast screen in the demonstration classroom, all turned pale with shock.

This is a life-threatening operation. Zhao Xu is just a resident doctor. Can he take on this important task? !

This is the doubt in everyone's mind at the moment.

Inside and outside the operating room, everyone's eyes were on Zhao Xu.

At this moment, even Sun Chang, who was standing next to Zhao Xu, felt tremendous pressure.

Will he be next?

Zhao Xu looked at Wang Ming, saw the trust in his eyes, nodded slowly, and said firmly to Wang Ming, "Director, I can do it!"

I can do it!
As soon as these words came out, although the voice was not loud, the people inside and outside the operating room had a deafening feeling.

Such a responsible young doctor is hard to find in the current medical environment.

"Let go and do it, everything is mine!"

Wang Ming nodded and encouraged Zhao Xu.

"Let me cooperate with you."

Sun Chang looked at Zhao Xu with a determined face, and suddenly said, at this moment, she, who is usually very rational, was also somewhat infected, and an inexplicable thing surged in her heart.

"Ah."

Zhao Xu nodded and looked at Sun Chang.

it is more than words.
