Chapter 2175

Mu Tao stood beside Wu as if he had never been before.

In the operating room, boss Zheng began to step on the line.

On the screen, the guide wire moves forward slowly and rests on the end of the ophthalmic artery a few minutes later.

Because the super selection should be as close to the retinal capillary network as possible, boss Zheng uses the thinnest guide wire.

It is thinner than the guide wire of Neurology intervention. It is the kind of guide wire specially for infants.

This kind of guide wire is soft and cotton. It can't use any force. Pleating in the process of over selection is particularly likely to lead to over selection failure.

However, seeing that the micro guide wire controlled by boss Zheng moved slowly, but there was no mistake or re operation, Mu Tao sighed.

"Mu Tao, do you know boss Zheng's technique?" Asked Wu.

"Teacher, it should be about the understanding of turbulence caused by blood flow in blood vessels." Mu Tao said, "boss Zheng has a deep understanding of turbulence. I think this is because he did a particularly good intervention."

"Yes." Old Wu nodded.

Overcoming the influence of turbulence is the most profound intervention theory and skill. After half a lifetime of interventional surgery, Wu was only vaguely aware that the guide wire and micro guide wire passed through the blood vessel, and the blood flow would have a great impact on it.

As for how to overcome it and increase the success rate of the operation, Wu was exposed.

Boss Zheng has mastered the skills of dealing with turbulence at a young age, which is admired by Mr. Wu.

This is a breakthrough at the technical level, but it is difficult to quantify and grasp.

The microcatheter entered, but did not go to the extreme position, but stopped in the blood vessel without touching the surrounding blood vessel wall.

At the beginning of angiography, as boss Zheng speculated, part of the retinal capillary network was blocked, which seriously affected the red blood cells carrying oxygen and provided "nutrients" for the retina.

After determining the condition, the operation continued. Su Yun connected a syringe at the end of the catheter and began to inject normal saline with a small amount of contrast agent.

His movements are slow, careful and delicate.

After normal saline entered the retinal capillary network, Su Yun began to increase the pressure slightly.

The "sticky" dye macromolecules are pushed forward by the normal saline injected by the syringe.

Because there is a gap between the catheter and the wall of the surrounding blood vessels, Su Yun has been carefully controlling his injection of normal saline to avoid capillary rupture and bleeding.

This step requires great patience.

When it's time, boss Zheng's operation is fast; When it was time to slow down, boss Zheng was not in a hurry and waited quietly.

time lapse.

After 12 minutes, the blocked position begins to move. Macromolecules deform under pressure, conform to the pressure of capillary wall, and are "pushed" away bit by bit.

Mu Tao knows that this is the most difficult part of the operation.

Here, we should constantly change the force slightly to make the pressure conform to the elasticity of capillaries.

Three minutes later, Su Yun stopped.

Mu Tao's heart moved and pressed the intercom. He didn't speak, but listened to the dialogue between Zheng Ren and Su Yun.

"Boss, I can't." Su Yun rarely admitted, "the tube wall is not well adapted to the sexy feeling. If you push it down, I think the capillaries are going to break. The power is small, and it has no effect."

"Oh, I'll do it." Zheng Ren took the syringe. "It's heart compression during liver transplantation. Your arm strain hasn't healed yet."

"Old fan rubbed me with Dieda wine for a few days, much better. But too detailed operation will take some time to do. You say how slow the operation is, it's an industrial injury!"

"Oh, OK, it's an industrial injury." Zheng Ren gave a light answer and didn't say much.

"Slow down!" Su Yun still reminded me uneasily.

"It's all right. I know." Zheng Ren said, "she is still young and the elasticity of retinal capillaries is good. I can feel the change of resistance. I will be very careful. Don't worry."

"Suya, you said how much trouble you have caused me." Su Yun began to nag.

"Brother Yun, I'm sorry." Xu Suya whispered, her voice trembling.

"Don't talk to the patient." Zheng Rendao, "the change of air flow during speaking leads to the change of the pressure of capillary network."

"There are so many things." Su Yun said contemptuously, "in fact, life is not as difficult as imagined. When you encounter difficulties, list all the solutions, and then you find that you can't do anything and give up directly."

I don't know whether I'm talking to boss Zheng or Xu Suya.

Mu Tao was stunned.

"Right, old mu." Su Yun then asked.

“……”

He knew he was eavesdropping. He was talking to himself. Mu Tao was speechless about it.

This is because I didn't do well in my own surgery. I don't say anything else, just interventional surgery. Who can guarantee that his operation can be better than boss Zheng? Bullshit!

Not only boss Zheng, he should not be able to compete with Su Yun.

Mu Tao smiled and pressed the button of the intercom again.

If you don't listen, don't listen.

Looking at the image on the screen, after boss Zheng took over, the overall operation speed seems to be no faster than that of Su Yun.

Many blocked black spots move invisibly and can hardly be found.

However, with the passage of time, 1 hour and 35 minutes later, Mu Tao called out the previous image and overlapped it.

This comparison is much simpler and more direct. The black spot movement of many blocking points is still obvious.

The operation is proceeding slowly.

No one spoke, and Wu and Mu Tao waited quietly.

Boss Zheng doesn't seem to be in a hurry. He is patient, feels the pressure transmitted from the syringe carefully, and adjusts his strength at any time.

An operation took four hours and 22 minutes.

The opening operation is countless times more difficult than the destructive embolization operation, which can be seen from the time.

When the dark shadow disappeared and the whole retinal capillary network was covered with contrast medium, Wu's body "softened" and then leaned back on the back of the chair.

The blood vessels covered with contrast agent, like the roots of plants, transport sufficient nutrients to the retina to let the patient see the light again.

The operation was successful. The teacher was too nervous. Mu Tao knew.

It's not difficult to see the operation. It's just to open the retinal capillary network. But those who are knowledgeable know the difficulty of this operation. If they don't pay attention, the operation will fail, and the patient may suffer permanent blindness.

However, this is only one eye.

"Boss Zheng, do you want to change your hands and have a rest?" Mu Tao pressed the intercom and said.

"Su Yun, are you tired?"

"Not tired."

"That's not necessary." Zheng Ren turned back and bent his eyes through the lead glass, leaving a smile for Mu Tao.
