It was Monday again, and Yan Feifan brought his student Pan Jichuan to the Department of Cardiology and was arranged to be Dr. Zhang Shi'an's surgical assistant to learn cardiac bypass surgery.

Cardiac bypass surgery is also a common type of surgery in cardiac surgery, which is used to treat vascular stenosis in coronary heart disease.

It is often associated with vascular interventional heart stents.

Both are effective surgical methods for treating vascular blockage and stenosis of coronary heart disease.

Interventional implantation of heart stents is a minimally invasive surgery and belongs to the business scope of cardiology.

The general procedure of the surgery is to make all the mouths in the radial artery of the arm or the femoral artery of the thigh, and use a thin and long catheter to enter the body along the blood vessels.

Under the guidance of x-ray fluoroscopy, the doctor manipulated the catheter from the peripheral artery to the coronary artery on the surface of the heart, placed the stent on the narrow part, and opened the blood vessels.

Cardiac bypass surgery is a business category of cardiac surgery and generally requires chest opening.

Opening the chest is to incite the incision in the middle of the chest, incising the pericardium, exposing the heart intact.

The blood vessels of the bypass are generally taken from the saphenous vein in the thigh, the intra-bladder artery in the chest or the radial artery in the arms.

One end of the blood vessel is sewn on the aorta and the other end is sewn on the distal end of the narrow area.

This is equivalent to building a "bridge" above the narrow place, allowing blood to bypass the blocked area to supply blood to the myocardium.

During the bypass operation, whether an extracorporeal circulation machine is needed to stop the patient's heart from beating depends on the difficulty of the operation, the technical level of the surgeon, and the hospital's equipment and equipment.

Chief physicians at the Department of Cardiac Surgery at affiliated hospitals have the ability to complete bypass surgery without stopping their heartbeat.

Both bypass surgery and interventional stent have their best indications and specific analysis should be made according to the patient's specific situation.

It is just because these two methods belong to two different departments, the suggestions given will inevitably be tendentious.

Generally speaking, if acute myocardial infarction or simple vascular stenosis, no more than three stents can solve the problem, or if you are old and weak, you can choose a heart stent.

If complex vascular stenosis and physical condition allows, cardiac bypass surgery is chosen.

Yan Feifan followed Dr. Zhang Shi'an to deal with the male patient, who was fifty-one years old this year, and needed two vascular bridges to solve his heart blood supply problem.

However, Yan Feifan and Dr. Zhang Shi'an were cleaning their hands and disinfecting them, but they were chased and found by someone.

It's Yu Suye!

"Doctor Zhang, sorry for disturbing me. The trauma surgery department sent a group of injured people in the accident, and one of the injured people arranged it to me."

"I came here to ask for help urgently."

As he said this, Yu Suye showed a bloody picture on his mobile phone to Yan Feifan and Dr. Zhang.

"This is an 18-year-old boy who graduated from high school and worked with his family after he came out to work for more than a month."

"Look at his right hand, he was directly photographed as a meat pie by the steel steel."

"Freefan, I thought about it all over the place, and you have the ability to restore his hands as much as possible."

Looking at the right hand pressed into a whole on the photo of the mobile phone, before Yan Feifan could make a sound, Zhang Shi'an spoke.

"Boy Yan, if you have this strength, go. You are only eighteen years old, your right hand is useless, and it will have a great impact on your life."

"This bypass surgery can be done for a day before learning."

Yan Feifan thanked Dr. Zhang for his understanding, and ran out of the cardiac surgery department with Yu Suye and went straight to Xiaohonglou.

Yu Suye told him that a steel structure project under construction collapsed and dozens of people were injured.

The operating rooms of the emergency department, trauma surgery and general surgery were not enough, so the injured person who had only severe injuries to his right hand was arranged to the operating room of Xiaohonglou.

Yan Feifan and Yu Suye came to the operating area on the third floor of Xiaohonglou. As soon as they walked into the isolation door, their cell phone rang.

It was a call from Vice President of Medical Affairs Liang Qing.

As soon as Yan Feifan answered the call, Liang Qing's voice rang out quickly, "Doctor Yan, is it convenient to come to the emergency department?"

"There is a critically ill-trained hemorrhage wounded. The brain surgery department cannot send people, but the emergency department cannot handle it."

"Now I'm just talking about you, Doctor..."

"I'll go there right away!"

Yan Feifan interrupted the other party rudely, and after replying, he reminded Yu Suye.

"Do debride first, process it slowly, and wait for me to come back."

After saying this, he rushed out of the isolation door.

This scene also made Yu Suye helpless.

One life and one hand, obviously one life needs Yan Feifan to rescue...

A few minutes later, Yan Feifan ran to the emergency department panting, then ran to the second floor and began to prepare for the operation.

When he was ready to enter the operating room, he saw a doctor lying on the operating table for an abdominal surgery on the injured person.

Yan Feifan came to the operating table and found that an oval surgical window of four by five sizes had been cut into the right skull of the wounded's head, and blood was flowing out...

He followed the blood flow and found an arterial bleeding point in the brain and a venous bleeding point, and performed vascular suture.

After Yan Feifan treated some other intracranial injuries, he threw the subsequent craniocerebral surgery to the surgical assistant from the emergency department and left.

On the way back to Xiaohonglou, Yan Feifan complained about the breaking regulations in the hospital forbidden to ride bicycles.

After he decided on this, he proposed to the hospital to add an electric two-wheeled or four-wheeled vehicle that only travels inside the hospital.

After all, the hospital does not cover a small area, and it takes more than ten minutes to walk from east to west, from south to north.

When encountering some emergency situations, medical staff can only run back and forth with two legs.

Yan Feifan had just ran to the front of the little red building, and his cell phone rang again.

This time it was Liu Jin's call.

"Extraordinary, there are three medical experts from Switzerland doing a visit to our hospital."

"They offered to show off and wanted to meet you!"

Yan Feifan replied directly: "Teacher Liu, I am about to undergo an emergency surgery and I can't leave for a while."

"Let's talk about it..."

Yan Feifan cleaned up and walked into the operating room of Xiaohonglou and saw Yu Suye tidying up the broken bones of the injured person's fingers.

He took the position of the main sword given up by Yu Suye and observed the injured person's right hand injury.

It's really hurt!

Yan Feifan saw that all the finger bones were broken, especially the thumb bones, which were broken into pieces.

"There is no possibility of recovery from the thumb."

Yan Feifan, who made the judgment, pondered for a moment and looked at the youthful face of the injured person who was in anesthesia and coma.

A bump was condensed into his eyebrows, and there was still fear on his expression. It seemed that he could still feel pain and fear in his coma.

Yan Feifan ordered: "Wake him up, I need him to make a choice."

"His right hand has many finger bones that are no longer available."

"One option is to transplant the toe bones as finger bones, and another option is to take a rib and polish it into finger bones."

Yu Suye couldn't help asking: "Or should you use a 3D printer to print artificial phalanx?"

Yan Feifan shook his head and said, "One is that the speed is too slow and takes too long, and the other is that it is rejection and acceptance."

"Don't forget the total hand bone replacement surgery we and Dean Chen did."

The surgery to replace the bone fragmentation with printed hand bones is strictly considered a successful operation.

But nearly two months after the operation, the injured person said that his hands were getting increasingly unbearable pain and itch.

Chen Yu had to perform surgery on him again and replace the artificial phalanx with his toes.

"There's a little more..."

Yan Feifan pointed out: "The cost issue."

"If there is a follow-up problem with the 3D printing phalanx surgery, it will be more difficult for him to go to the responsible party to ask for the surgical fee."

Yu Suye nodded, turned to look at the anesthesiologist, signaling that he could wake up the wounded...
