Chapter 877 Zou Wei's Invitation

Lu Chen gave the patient's valve lesion very accurately, such as morphology, location, degree of calcification, etc.

As the surgeon in charge, Shi Langqin received all the information about the valve at the first time.

He immediately began to perform aortic root angiography to clarify the morphology of the aortic sinus and the location of the coronary artery opening.

As an assistant, Jin Miao assisted Shi Langqin and began to perform vascular puncture.

Lu Chen stood next to the operating table and had a full view of the two people's operations.

Compared with the operations three years ago, their level has improved significantly.

Even if placed on a national scale, their level can be ranked first.

…

Under the guidance of the 14fr Cook sheath, Shi Langqin inserted a 22mm balloon and pre-dilated it twice.

However, after completing the above operations, Shi Langqin suddenly stopped his movements.

"Director Lu, what type of valve should this patient choose?"

Compared with surgical skills, in various interventional surgeries, there is another very important point, that is, to assess the severity of the lesion and choose the most suitable artificial valve.

The choice of artificial valve directly affects the success or failure of the operation.

Usually, patients will undergo detailed CT evaluation before the operation to select the best one.

However, for emergency TAVR surgery like this, it is difficult to choose the most suitable stent without preoperative examination and only rely on intraoperative ultrasound examination.

However, in this operation, as the operator of the ultrasound machine, Lu Chen has a unique advantage.

He observed the ultrasound image again, carefully compared and evaluated the balloon expansion effect and the size of the valve ring structure, and then slowly said: "Professor Shi, choose the J-Valve 25mm valve."

"Okay." Shi Langqin believed in Lu Chen's words and directly ordered Jin Miao to bring the 25mm valve.

The valve began to be delivered.

Although Shi Langqin was a little older, his hand movements were not unfamiliar at all.

The valve was delivered, released, and fixed.

The whole process was done in one go.

After the valve was fully released, Lu Chen confirmed the good position and function of the valve through ultrasound.

Afterwards, Shi Langqin used balloon dilatation again, and no clear paravalvular leak was found. The effective valve ring diameter after the stent was expanded was about 25mm.

"Great, it's a success!"

Shi Langqin and Jin Miao's eyes were full of excitement.

With Director Lu Chen here, the effect is different.

After the operation, the patient immediately showed significant hemodynamic improvement.

The peak AV velocity of the valve dropped from 12.33m/s to 3.2m/s!

Epinephrine dropped from 0.3μg/kg/min to 0.1μg/kg/min, and norepinephrine dropped from 0.8μg/kg/min to 0.3μg/kg/min!

The amount of rescue medication was greatly reduced, which proved that the patient's heart function was gradually recovering.

Secondly, in Lu Chen's eyes, the patient's life value decline rate has been slowly slowing down.

The three minus signs on his head have also become two!

"Send back to the CCU for further observation, and catecholamine vasoactive drugs can be gradually reduced to stop." Lu Chen reminded.

"Okay, Director Lu." Jin Miao nodded.

Postoperative care and prevention of complications are also very important.

Cardiology interventional surgery is fine, but many surgical operations, even if they are done beautifully, can easily cause infection if the postoperative care is not proper, resulting in the failure of the entire operation.

…

Doctor-patient communication room.

Shi Langqin had taken off his mask and hat, and said to the patient's family: "The operation was very successful! It lasted for 120 minutes in total. Under strict anesthesia monitoring and management, no adverse cardiac events such as cardiac arrest or malignant arrhythmia occurred during the whole process."

The family member was a middle-aged woman. When she heard this, she was so excited that she trembled. "That's great, that's great! Professor Shi, you are really living Bodhisattvas!"

Shi Langqin smiled slightly, "You are lucky this time. The expert who just came back from Mayo in the United States happened to be inspecting our hospital. With his full participation in this operation, the safety of the operation has been greatly improved."

"Thank you, thank you!" The middle-aged woman thanked him again, and at the same time said to a man behind her, "I told you that you should come to the Central Hospital. Fortunately, you didn't go to Guanghai First Hospital..."

Hearing the conversation between the family members, Shi Langqin smiled and left.

"Director Lu, thank you so much this time."

In the lounge, Shi Langqin personally poured a cup of tea for Lu Chen.

You know, Professor Shi Langqin, who is almost fifty years old this year, personally poured tea for a junior.

This is enough to show how much he values ​​and admires Lu Chen.

Lu Chen quickly stood up, bowed slightly, and took the cup of tea, "Thank you, Professor Shi, I am just playing an auxiliary role, aren't you still the real surgeon?"

Shi Langqin smiled, Lu Chen's attitude made him a little embarrassed, he immediately changed the subject: "Director Lu, our hospital and our department really want you to come. With your joining, we will definitely be even more powerful, and in time, we will definitely be the top 1 in the domestic tavr field!"

Jin Miao on the side also nodded quickly.

Lu Chen smiled, "Professor Shi, I understand your intentions. This matter is not urgent, let me go back and think about it."

"Okay." Shi Langqin smiled embarrassedly, "I am a little impatient."

He also knew that there must be many people who came to see Lu Chen.

Among them, there are definitely many that are better than Guanghai Central Hospital.

…

After leaving Guanghai Central Hospital.

Lu Chen went to the appointment and had dinner with Xu Wei.

The next day.

A sudden phone call made Lu Chen change his next schedule.

"Hello, Professor Lu, are you busy?"

A male voice came from the phone.

Lu Chen felt a little familiar, but he couldn't remember who the other party was.

"Excuse me, who are you..."

"Professor Lu, I'm Zou Wei!" A hearty laugh came from the other end of the phone.

"Zou Wei?" Lu Chen murmured in his mouth, feeling a little familiar, but still couldn't remember.

"The nephew of Director Zou Yi of the Magic City Science and Technology Bureau."

"Oh?" Lu Chen had some impression.

"It was the one who was bitten by a tick. Other hospitals said that a pacemaker should be placed." Zou Wei continued, "Then I came to you and found out that the slow heartbeat was caused by the tick bite, so a pacemaker was not needed."

"Oh!"

When it came to the specific disease, Lu Chen remembered it all of a sudden.

"It's you! I remember it! What's the matter?"

Zou Wei laughed, "Director Lu, I heard that you returned to China?"

"Yes, you are well-informed." Lu Chen said.

"In Guanghai?" Zou Wei said again. UU看书www. uukａnshu.net

"Yeah."

"Are you busy now? I'm in Guanghai right now and I want to treat you to a meal."

"Sure." Lu Chen thought about it and realized that he didn't have anything to do in the afternoon.

"Okay, Director Lu, I'll send you the address."

After hanging up the phone, Zou Wei sent Lu Chen the address of a five-star hotel.

"This kid is really rich?!"

Lu Chen smiled.

Although he didn't know Zou Wei's intention to find him, it was a good thing to have one more friend.

At 1:00 in the afternoon, Lu Chen rushed to the five-star hotel.
