Director Li Lishan stared at Yuntian surgery without blinking.

didn't wait long, Director Shi and Director Lin also arrived.

Poor Manager Huang was squeezed into the corner of the disposal room again.

"M2 paragraph?" As soon as Director Shi and Director Lin arrived, Director Lin asked eagerly.

"Why are you here?" Director Li Lishan didn't expect Director Shi and Director Lin to get the news so quickly.

"My student, such an important operation, will naturally tell me as soon as possible. "Scolding Director Li Lishan is obviously Director Shi's greatest pleasure.

Director Shi, who has always been gentle and elegant, will always be a little more sour when facing Director Li Lishan.

However, with Director Lin here today, it is rare that Li Lishan's artillery has not been ignited.

"Is it suction?" Director Shi asked in surprise when he saw Leng Chengye connecting the negative pressure suction machine.

"M2 section, isn't it the best way to do suction?" Director Li Lishan raised his eyebrows and asked rhetorically.

The contempt revealed in it is self-evident.

Director Shi rarely didn't reply, his eyes stared at Yuntian, and he didn't blink.

Able to complete the middle cerebral artery M2 segment, it is a neurointerventional surgeon who steps on the top of the pyramid to sign surgery.

If we can really complete the M2 surgery of the middle cerebral artery tomorrow, then our neurology department will definitely be able to develop very quickly.

Although Leng Chengye has not been exposed to negative pressure suction devices, he is a bright star in Massachusetts neurology after all.

The self-learning ability is naturally not ordinary, and it only takes a short time to connect the microcatheter to the negative pressure suction device.

Yun Tian began to twist the microcatheter in his hand and slowly traveled towards the blood vessels.

From the vertebral artery to the middle cerebral artery, it is not difficult for Yuntian at all.

As the microcatheter travels to the M1 segment of the middle cerebral artery, the speed of the clouds slowly decreases.

However, it is still very stable, and the microcatheter travels slowly through the blood vessels.

"M1 section, you are so stable!" Leng Chengye was stunned.

"How many M1 segments have you done in the past few days?" Although the M1 segment cannot be compared with the M2 segment, it is also an extremely difficult cāo) site, and being able to complete the M1 segment of the middle cerebral artery indicates that the surgeon has reached the advanced level of neurointervention.

I haven't seen it for a few days, and Yuntian's M1 section cāo) is so stable, which makes Leng Chengye can't believe it at all.

"Well, four, probably. Yun Tian's hand did not stop, and replied casually.

"Sitai?" Leng Chengye estimated in his heart.

If I made four M1 steps by myself......

Thinking about it this way, Leng Chengye was even more unsettled.

No matter what kind of technique, if you do four of them, you can't even be familiar with them. Not to mention the difficult part of the middle cerebral artery, the M1 segment.

Therefore, Leng Chengye's heart was shocked, can the four M1 section cāo) work reach this level?

Leng Chengye looked at Yun Tian as steady as an old dog, and slowly traveled in the blood vessels with a microcatheter, feeling that the whole world was messy.

"Open the negative pressure suction, the maximum negative pressure suction - 100KaP,

Lasts 90 seconds to attract. Yun Tian felt the position of the microcatheter and said to Leng Chengye.

"Huh?" Leng Chengye was immersed in a sense of loss and powerlessness, and did not hear Yuntian's order.

"Turn on the negative pressure suction, the maximum negative pressure suction is -100KaP, which lasts for 90 seconds. Yun Tian repeated.

Leng Chengye heard the order clearly, and began to prepare to connect the negative pressure suction device.

After the suction is completed, the negative pressure of the microcatheter is maintained, and Yuntian begins to withdraw the microcatheter.

Everyone stared with bated breath at the condition of the microcatheter in Yun Tian's hand.

"Definitely reincarnated. Director Li Lishan clenched his fists and said in a hoarse voice in the disposal room.

"Well, there must be rebleeding. "It's rare for Director Shi to have the same opinion as Director Li Lishan, and he has the same hoarse voice.

"Xiaoyun cāo) will definitely be able to regain blood. Director Lin hugged Director Shi's arm and pinched it fiercely.

Director Shi frowned, returned his hand, and patted Director Lin's hand gently:

"Don't worry, Xiaoyun will definitely succeed!" Director Shi said.

"Hmm. Director Lin nodded vigorously.

"Xiaoyun will definitely do it. Director Li Lishan, who had always been disgusted with the appearance of Director Shi and Director Lin, felt that the appearance of the two directors Shi and Lin in front of him suddenly seemed insignificant compared to whether the Yuntian M2 section of the suction plug in the studio could be successful at this time.

Yuntian withdrew the microcatheter little by little, and several people seemed to be more nervous than Yuntian.

Including Manager Huang, the four people in the disposal room clenched their fists, and the hands of several people trembled slightly.

And cāo) as an indoor, Yun Tian's hand, must be very stable.

"There is blood return!" Director Li Lishan's viewing position was the best, so he was the first to exclaim.

"Is there any blood return?" Director Lin leaned his head to Director Li Lishan's side for the first time, excitedly wanting to see it clearly.

"There's blood, look at it from me. Director Shi stretched out his hand, gently held Director Lin's head and said.

"There's blood, there's blood, and it's always been, it's always been there, you see, it's always been there. Director Lin didn't notice Director Shi's careful eyes at all, and almost jumped up excitedly, pointing to the microcatheter in Yun Tian's hand in the work room.

There is blood return in the retracted microcatheter, indicating that the previous aspiration was unobstructed.

If there is continuous blood return, blood flow to the blood vessels has been restored.

There is a high probability that the surgery was done successfully.

Therefore, seeing that the microcatheter in Yuntian's hand had a continuous blood outflow, the four people in the disposal room were extremely excited.

Director Lin and Director Shi hugged each other excitedly and cried.

Director Li Lishan, after grabbing Manager Huang, slapped Manager Huang on the shoulder.

Fortunately, Manager Huang held his breath and worked hard.

"There's continuous regeneration, this kid, okay. Director Li Lishan was also very excited.

The same goes for Manager Huang.

The microcatheter is withdrawn to the vertebral artery and a contrast medium is injected again.

There were four people in the disposal room, two by two, all holding each other's hands tightly.

In the room, Leng Chengye also held the pressurized injector

Glued to the image on the screen.

The contrast agent is like a firework that blooms, following the flow of blood, and instantly spreads on the screen.

The vertebral artery meandering image appears on the screen, like a flexible vine,

The vertebral artery blood flow circulation is not bad, no obvious stenosis is seen, the vine has been spreading downwards in good condition, and no obvious loss is seen.

Next, there is the beginning of the middle cerebral artery, which is significantly thinner than the vertebral artery after a shunt.

And it was more circuitous, but the blood flow was still very good, and similarly, the vines that swirled around showed no obvious defects.
