Chapter 341 Do Your Best

"Mr. Zheng, I'm Lao Zhou from the Department of Orthopedics." A slightly motherly voice came from the other side of the phone.

It's Dr. Zhou from the Department of Orthopedics. He's a nice guy, but he's a little bit of a motherfucker.

The voice was so recognizable that Zheng Ren recognized it right away.

"Brother Zhou, what's the matter?"

"Are you busy? Lumbar spondylectomy, interventional surgery for the patient..." On the other side of the phone, the voice hesitated, "Can the surgery be done in a while?"

Um? Why are you in such a hurry?

"I don't have anything to do now, is the patient fasting enough?" Zheng Ren said indifferently.

"Enough! Enough!" Dr. Zhou said hastily, "This operation is performed by a professor from the imperial capital. The professor has something to do from time to time, so he either flies in tomorrow morning to do it, or he needs to wait three or five days later."

Doctor Zhou hastily explained that after all, it was almost time to get off work, and Zheng Ren's operation was based on personal feelings.

"The patient is in severe pain and needs to use a large amount of drugs for pain relief every day. Didn't I think that the sooner it is done, the patient will suffer less."

"It's okay, Brother Zhou. I don't have emergency surgery here. If it's convenient for you, let the family members sign it, and you can send the patient directly." Zheng Ren said with a smile.

"Okay, okay." Doctor Zhou agreed hastily, "I'll let the family members find you right away."

After speaking, the phone was hung up.

Zheng Ren immediately began to write the pre-operative explanation by hand. Because it was the first time to do a new operation, Zheng Ren recorded the possible complications while thinking about it.

Seeing that Zheng Ren started working, the professor leaned over and asked, "Boss Zheng, do you want to operate immediately?"

"Yes." Zheng Ren replied.

"Your work here really does not divide day and night." Seeing that he had to leave work and have surgery, as a rigid German, the professor must have an idea.

Off-duty time is private, and the professor is really not used to this kind of rhythm of life that does not distinguish between public and private.

This is no life, it is simply a slave sold to a hospital.

But the professor was still reluctant to leave, even though Zheng Ren would not stop him if he wanted to leave.

The 3D reconstruction of the 64-slice CT at noon opened a door for the professor to vaguely see a brand new world.

As for the scenery of this world, perhaps we can see the clue from this operation.

The professor only hesitated for a second before making up his mind to stay.

Zheng Ren didn't know the professor's rich inner drama at all, he proofread the pre-operative explanation one by one, and when the young woman came, Zheng Ren was still thinking hard about various possible complications.

Write down everything you can think of and explain it to the patient's family.

It doesn't matter to the young woman. In her words, this is the time when the family members do their best and ask the doctor to help.

Moreover, she has also done a good job of psychological construction. If she really can't step down, she should suffer less.

Without hesitation, she signed the preoperative statement that Zheng Ren had printed out, and then went back to send the patient to the emergency ward for surgery.

Zheng Ren called the operating room to prepare for the operation, but he didn't call Su Yun and took the professor to the operating room.

Finally, when Zheng Ren had time, Professor Rudolph kept asking questions about the 3D reconstruction of 64-slice CT that he just thought of.

Zheng Ren didn't have the heart to answer the professor's questions. He lowered his head and changed his clothes, only occasionally communicating with the professor.

All he could think about was issues related to the embolization of the transverse lumbar artery.

It is still necessary to go to the system operating room for training. Ten or twenty operations experience is enough.

Now that Zheng Ren has a lot of money and wealth, the new technique he encountered for the first time, if he thought about it, he had tried ten or twenty times.

As for how many hours it would take each time, Zheng Ren didn't think too much about it.

If this were done before, it would be absolutely impossible.

From simplicity to extravagance, this is the reason.

After changing his clothes, Zheng Ren asked Professor Rudolph to prepare for the operation, while he went to the small smoking room, lit a purple cloud, and entered the system space.

After buying surgical training time, the system operating room rose from the ground, and the experimental subject appeared in front of Zheng Ren.

The lumbar artery, also known as the transverse lumbar artery, divides into two terminal branches, anterior and posterior, on the anterolateral side of the intervertebral foramen.

The anterior branch runs along the corresponding inferior border of the transverse process and the ventral side of the intertransverse ligament, passes through the posterior transversus aponeurosis between the transversus abdominis and the internal oblique muscle, and supplies the posterolateral abdominal wall tissue.

At the beginning of the posterior rami, a thinner anterior intervertebral branch emerges from the front edge of the intervertebral foramen into the spinal canal to support the area in front of the dura mater and behind the vertebral body.

At the same location, the trunk of the posterior ramus sends out the vegetative branch that enters the trunk of the lumbar plexus.

What needs to be embolized is not only the nutrient branch that sends out from the posterior branch and enters the lumbar plexus trunk, but also the abnormally proliferated feeding vessels of the trunk and the abnormally proliferated blood vessels of tumor tissue.

This point has been determined during the 3D reconstruction of the 64-slice CT at noon.

Because the patient has an advanced tumor, the operation performed is also a palliative operation to improve the quality of life, so while avoiding complications, try to embolize the feeding vessels of the vertebral body.

Simple destructive surgery is not that difficult. In the past, for this type of operation, without interventional embolization of the transverse lumbar artery, the blood loss during the operation should be 3000-5000 ml.

This is a daunting number.

However, if the transverse lumbar artery is embolized, the bleeding volume can be controlled at 1500-2000 ml, which is acceptable.

For surgical training, Zheng Ren did the first operation for nearly 3 hours.

Because Zheng Ren didn't want to just bolt off the posterior branch. Although the operation is relatively simple, it can still reach the level required by the imperial orthopedic professor.

However, the intraoperative blood loss of the patient is about 1500 ml, which will still have a huge impact on the dying patient.

In order to improve the quality of life of patients during their lifetime, it is only serious to have as little bleeding as possible.

Not only the transverse lumbar artery or the left and right intercostal arteries should be embolized, but also the nearby small blood vessels should be embolized as much as possible to minimize surgical bleeding.

In fact, Zheng Ren didn't need to do this at all.

However, as a doctor, when conditions permit, I always want to make the patient recover as soon as possible. And those who cannot be cured, try to improve the quality of life during the survival period.

The spinal cord is extremely rich in blood vessels. Except for the Adamchiviz artery, which should be avoided as much as possible, the rest of Zheng Ren also took an angiogram carefully. It was found that it did not affect other organs or the spinal cord, and it was simply supplying blood to the tumor, so it was blocked.

The operation proceeded very slowly, and Zheng Ren gradually mastered some corresponding embolism techniques.

The master level of intervention is not a joke.

Even so, after doing ten surgical trainings, it was only possible to complete one embolization operation of the transverse lumbar artery every two hours.

To a certain extent, this kind of operation is more difficult than prostate embolism to meet Zheng Ren's requirements.

After all, even if the hyperplastic capillaries of the prostate are ectopically embolized, it will not lead to the death of the patient.

Just like the patient made by Professor Rudolf Wagner, the superior bladder artery was embolized, and the patient only had symptoms such as urinary inability, and an indwelling catheter was enough.

This time, however, it was the arteries near the blood vessels feeding the spinal cord that were to be embolized.

If one is not careful, the patient will suffer from paraplegia of the lower limbs, and even respiratory arrest, resulting in death of the patient.
