At this moment, a sound came from the intercom.

"Xiao Feng, you need a balloon stent. If you want a small balloon, it's fine with a diameter of 1.4mm. Just need a bare metal bracket. Do you need another boss?"

"No more." Zheng Ren only said two words.

Feng Xuhui, standing in the corner, limped and held a bunch of consumables, bent his waist slightly, and walked to the side of the tour nurse.

He skillfully took out a few consumables and handed them to the circuit nurse.

Without saying a word, Feng Xuhui once again "flashed" to the corner of the wall.

Zheng Ren then implanted the balloon stent along the femoral vein into the patient's severe stenosis of the pulmonary vein.

The patient's pulmonary vein was close to the occlusive lesion. Zheng Ren used a small balloon with a diameter of about 1.40mm for pre-diffusion and was very careful in his movements.

He did this step very slowly. If the previous surgery was so fast that it was dazzling, then this step was so slow that it was outrageous.

The two styles switched instantly, although they were abrupt, but the person who watched the surgery did not feel anything was wrong.

It took 5 minutes before Zheng Ren opened a gap in the obstructed pulmonary vein.

The bare metal stent is placed after the balloon is expanded and slowly opened.

The imaging of the left pulmonary vein that had been disappearing reappeared.

Zheng Ren turned around and stepped down.

"After the operation, warfarin, chlorograrel and aspirin were used for antiplatelet and anticoagulation treatment. The treatment time was maintained for more than half a year, and the international standardization ratio was adjusted to 1.6-2.6."

Professor Wu immediately wrote down what Zheng Ren said.

These are conventional treatment methods, and there are no unexpected "magical" treatment methods, but he still carefully recalled them.

After confirming it, Professor Wu asked: "Boss Zheng, you must be sure it's not lung cancer."

"Well, it's very certain that it's caused by pulmonary vein occlusion." Zheng Ren said: "The patients will recover quickly after the operation."

“Use and give it…”

"There is no need to send severe illness, and there is nothing special. Just go back to the department to continue correcting the anemia." Zheng Ren said: "If you are worried, slow down the speed of drip and do not exceed 40 drip per hour. Let me explain this to the nurse."

After saying that, Zheng Ren walked out of the operation room and saw Su Yun crossing his legs, holding the mouse in his right hand and doing the silhouette after the operation.

"Old Li, it's okay." Zhou Chunyong stood on the side of the patient's head and whispered to the patient.

"Lao Zhou, who did the surgery for me?" The patient had no feeling, and the surgery was over. When he heard the conversation in the operating room, he felt a "illusion" of getting out of danger.

"It's Boss Zheng I always tell you. Look at you, you don't tell me earlier if you have something to do. You have suffered so much crime." Zhou Chunyong complained.

After saying that, Zhou Chunyong looked at Professor Jiang and smiled and said, "Xiao Jiang, the operation took 12 minutes. What have you learned?"

Professor Jiang was muttering with a bitter face.

The surgery should be done quickly, and when it should be slow, and when it should be slow, and the movements are appropriate.

I know all the steps myself. Although I haven't done it a few times, Boss Zheng did not use the method of flying immortals in the sky for the surgery.

But it is the simplest surgical method, which is combined step by step, causing the entire surgical process to change greatly.

Simple, clean, neat.

Professor Jiang did not hear Zhou Chunyong's ridicule. While doing the final work, he recalled the operation process in his mind.

...

"Boss, wait for Lao Zhou for a while, don't rush to change your clothes." Su Yun's hand gently tapped on the mouse, and a clattering sound was made.

It sounds very slow, but every step of making silhouettes is extremely accurate.

"Well, let's make a movie and give it to Director Zhou." Zheng Ren said.

"Doctor Zheng..."

"Who are you? Doctor Zheng, what do you know? "Su Yun didn't look back and almost overturned the operating table with a contemptuous tone.

"Uh..." Lin Yuan was angry!

This is a habit in the United States. It is something that many people dream of to call him Dotor Zheng.

Doors are not good, do you have to call them boss?

However, after a surgery, Lin Yuan saw the trick.

This Dotor Zheng’s surgery is better than his tutor…even than anyone who can do interventional surgery at Harvard Medical School!

It is not because of the speed, but because the guide wire is implanted from the beginning to the end, the whole process is one order of geometric magnitude higher than others.

"Whatever you want, it's okay." Zheng Ren was nothing. He said casually while watching Feng Xuhui pack up his things.

"Boss Zheng, can you tell me how you judge the stenosis of the pulmonary vein?" Lin Yuan asked respectfully.

"The pulmonary veins play a very important role in the triggering of atrial fibrillation. Most paroxysmal atrial fibrillation originates from the pulmonary vein. Therefore, understanding the connection between the pulmonary vein and the left atrium is crucial before the frequency of atrial ablation." Zheng Ren took out a consumable from Feng Xuhui's large trolley case and looked carefully.

When he talked to Lin Yuan, he just talked casually, and seemed to be blind.

"Xiao Feng, when I go back, I'll make a list for you." Zheng Ren said: "I still lack something, so you can do it."

"good."

"What is in Liu Xiaojie's trolley case?"

"Mr. Zheng, her trolley box is filled with spare ordinary consumables. I am worried that when I encounter large-scale rescue, I will prepare ten servings for each ordinary consumable on that side."

"It's almost done." Zheng Ren smiled and then shouted, "Director Zhou!"

Zhou Chunyong said to Lao Li and immediately ran out happily.

"Boss Zheng, what orders are you?"

"Don't be so polite. I just used the consumables. Please say hello to this side." Zheng Ren said, "I'm going to find Manager Feng, please have his contact information."

"Don't worry, Boss Zheng." Zhou Chunyong said: "Don't worry about small matters such as purchasing. Just contact Manager Xiao Feng."

Zheng Ren nodded and handed the consumables in his hand to Feng Xuhui.

Lin Yuan stood aside, silently in a daze.

Did this boss Zheng completely ignore himself? Why did he stop talking about pulmonary vein stenosis?

He is a pride of heaven and has been a top student since childhood. Even if he goes to Harvard Medical School, he will not be at all disadvantages.

Even after she was engaged in bioengineering research, she was specially recruited to the clinical department after participating in a surgery by chance.

Lin Yuan, who has never been ignored by anyone, really doesn't believe that he was actually ignored by this boss Zheng.

She felt that her outlook on life was subverted, and she silently watched the patient being sent away, silently watched the consumables close the big trolley case, and limped to leave with Boss Zheng and the sarcastic guy.

I was really ignored and didn't even have a word of chatting. Lin Yuan finally discovered that this was a fact.

Not only did he not meet up with him, he did not even have the most basic polite and polite greetings. In Dr. Zheng's eyes, he did not exist at all.
