Yun Tian brushed his hands out, and when he saw Zhao Lei making the last step of preoperative preparations--- making a big order, Yun Tian stopped smiling.

Although Lao Zhao's growth rate is not as fast as Leng Chengye's pervert, it is indeed attentive.

Yuntian waited for Zhao Lei to lay out the last layer of the list, and then motioned to Zhao Lei to brush his hands.

As for himself, he could only raise his hands and drag the only stool for the operation over and sit aside and wait.

Out of trust in Director Li, Yuntian brushed the patient's hands as soon as he pushed the patient up, and made preoperative preparations.

The rest, but wait for Director Li's good news.

The operation can only be performed after Director Li obtains a consent form signed by the patient's family.

So, many times, the patient's life is not in the hands of the doctor, but in the hands of the person who is closest to him.

There are often cases where the doctor is ready for surgery and waits in the operating room for an hour or two before the signature is done.

There are also many people, because the family does not make a decision in time, and in the end the doctor can only watch the patient's life slip away little by little, and in the end, the family blames the doctor for not treating it in time.

But this patient, because Director Li said before, the patient's family has a strong desire to do interventional thrombectomy.

Coupled with his trust in Director Li, Yun Tiancai finished brushing his hands at the first moment, waiting for Director Li's good news.

Director Li didn't let Yuntian wait long, just for a while, Zhao Lei hadn't finished brushing his hands, and Director Li had already appeared in the disposal room in a hurry.

Raising the letter of consent in his hand to Yun Tian, Director Li pressed the walkie-talkie:

"The patient's family has signed off and is ready for surgery. ”

Yun Tian nodded at Director Li, and began to put on his hands, ready to go on stage for surgery.

The same is to take the femoral artery and put it in the sheath, Yuntian is very fast, and the disinfection and puncture are completed, and the micro-guidewire and microcatheter are used for the blood vessels and start to travel.

It stops until it reaches the branch of the internal carotid artery and is impounded.

Blood flow distal to the middle cerebral artery is absent.

The position in the M1 segment is gone.

Such a vascular sign naturally indicates that the patient has an infarction of the middle cerebral artery.

Director Li nodded, his judgment was indeed not wrong, it was an infarction.

Such angiography images have shown that the patient has an infarction in the middle cerebral artery.

Yun Tian's expression did not change in the slightest, and after entering the bracket, after adjusting to the most suitable position by feeling, he opened the bracket and began to drag back.

But compared with Yun Tian's travel speed in the large blood vessels, Yun Tian can even be described as super slow when he drags back the stent at this time.

It's even slower than when Yuntian controls the microwires to pass through the middle cerebral arteries.

In general, such a slow cāo would not be chosen under normal circumstances.

Although, it's not wrong, it's definitely a method that most doctors don't choose.

Therefore, Director Li was a little puzzled.

I wanted to press the walkie-talkie to ask Yuntian for an understanding, but after raising his hand, Director Li took it back.

Director Li still has a good understanding of the situation in Yuntian.

I can't do it if I don't understand it

After all, Director Shi would deliberately go to the emergency department every once in a while, intentionally or unintentionally mentioning Yuntian's recent situation.

Director Li knows that that guy is showing off!

In terms of liking Dese, Director Shi and Director Lin are the same.

It's just that Director Shi's methods are gentler and more hidden, and there is no rampant and hatred that Director Lin came.

Although Director Li felt that it was a pity that he had missed a good apprentice, he was still pleased with Yuntian's current achievements.

Therefore, Director Li knew that Yun Tian had completely mastered emergency interventional thrombectomy during his time in the imperial capital.

Moreover, Yun Tiancai has just completed a case of thrombectomy of the M1 segment of the middle cerebral artery, and he is still a patient with moderate anemia and septic shock.

Although the current patient's condition is complicated, in terms of the difficulty of cāo) alone, it is at least slightly less difficult than that of the patient in the respiratory department.

It's just that this patient's condition is much more complicated.

Yuntian slowly dragged back the stent, because at this time, the stent was traveling at the distal end of the embolization, and the contrast agent could not pass through, and only the shape of the stent could be seen, but the blood flow and the condition of the blood vessel wall could not be seen.

The cloudy cāo) is all based on its own feel.

Yuntian slowly dragged the stand back.

When approaching the position of blood flow, the stent suddenly deformed violently, and it seemed that the resistance suddenly increased a lot, and Yun Tian paused slightly in pulling the stent.

Director Li's eyes flashed!

This is......!

It turns out that there is indeed a narrowness!

As long as the texture is relatively hard, this situation occurs when the whole stent travels through the blood vessels.

Looking at the degree of stent deformation just now, the narrowing of the blood vessels is very serious!

Is it really because of the stenosis?

Director Li looked at Yuntian.

This kid, unconsciously, has actually grown to this extent!

With the facts in front of him, Director Li had to admit that Yuntian's level in the direction of imaging diagnosis had obviously surpassed his own.

After passing through the narrow area, the speed of the cloud sky to drag back the bracket is significantly accelerated.

After the stent was dragged out, there were two small, irregularly shaped blood clots.

"It's embolism. Seeing Guan Yuntian dragging out two small blood clots, Zhao Lei said with a little loss.

Zhao Lei watched the communication between Yuntian and Director Li before, and while envying Yuntian for having a level that can question the director, he naturally hoped that his diagnosis as a demonic classmate was correct.

Unexpectedly, with such good luck, two blood clots were dragged out for the first time.

Zhao Lei's level has obviously not reached such a subtle point as discovering the deformation of the stent, and he has not been able to determine that the patient is indeed mainly stenosis through the deformed stent, as Director Li did.

In Zhao Lei's simple thoughts.

Pull the blood clot, and it must be an embolization.

"Turn on the pressurized injector and re-image. Yuntian didn't comfort Zhao Lei's loss, but just reminded him softly.

Zhao Lei hurriedly turned on the pressurized injector, and with the injection of contrast agent, the condition of the middle cerebral artery appeared on the screen.

With blood

The plug is removed, and the middle cerebral artery already has a blood flow signal,

However, at this time, the blood supply to the distal middle cerebral artery is very poor.

The blood flow is very small, apparently not to the extent that it can meet the needs of brain cells.

Moreover, at the site of embolism between the middle cerebral arteries, a very obvious loss of blood signal can be seen.

This is a condition in which the arteries are evident with plaque masses that cause stenosis.

"Is narrowness so serious?" Zhao Lei said in surprise, and Zhao Lei's voice was a little excited.

Yun Tian didn't smile, this guy, he and Director Li just have different diagnostic opinions, this guy is too involved, right?

Seeing that he had dragged a blood clot, the whole thing was wilting, and at this time, the imaging again found that it was severely stenosis, and he was excited as if he had been beaten with chicken blood.

Although I feel that Zhao Lei's sense of change is too rich, there is still a faint warmth flowing through my heart.

"Then is this main reason because of stenosis or because of blood clots?" Then, Zhao Lei had a new question.
