"Mr. Zheng, I am the old Zhou of orthopedics. There was a slightly motherly voice on the other end of the phone.

It's Dr. Zhou from the Department of Orthopedics, he is very nice, but he talks a little girly.

This voice was too recognizable, and Zheng Ren could hear it at once.

"Brother Zhou, what's wrong?"

"Are you busy?lumbar spondylectomy, the patient's interventional surgery ......" on the other side of the phone, the voice was a little hesitant, "Can the surgery be done in a while?"

Hmm, why are you in such a hurry?

"Now that I'm fine, is the patient fasting for enough time?" said Zheng Ren, who didn't care.

"Enough! enough!" Dr. Zhou hurriedly said, "This operation is done by a professor from the imperial capital." The professor was faced with something from time to time, and he would either fly in early tomorrow morning to do it, or he would have to wait three or five days to talk about it. ”

Dr. Zhou hurriedly explained that after all, it was close to the time to get off work, and it was a matter of personal feelings to find Zheng Ren for surgery.

"The patient was in terrible pain, and he had to use a lot of drugs every day to relieve the pain. Didn't I wonder if the sooner I did it, the less sin the patient would suffer. ”

"It's okay, Brother Zhou, I don't have emergency surgery on my side, 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.

"Good, good. Dr. Zhou hurriedly agreed, "I'll let the family go to you." ”

With that, the phone was hung up.

Zheng Ren immediately began to write the preoperative explanation, because it was the first time to do the new procedure, Zheng Ren wrote it down while pondering the possible complications.

When the professor saw Zheng Ren starting to work, he leaned over and asked, "Mr. Zheng, are you going to have surgery immediately?"

"Hmm. Zheng Ren replied.

"Your work is really day and night. "Seeing that he has to leave work and have to go to surgery, as a stereotypical German, the professor must have an idea.

Off-duty time is private, and the professor really doesn't adapt to this rhythm of life that doesn't distinguish between public and private.

Where is this life, it is simply a slave sold to the hospital.

But the professor was reluctant to leave, although he wanted to go, Zheng Ren would not stop him.

The 64-slice CT three-dimensional reconstruction at noon opened a door for the professor to vaguely see a new world.

As for the scenery of this world, we may be able to see a clue from this operation.

The professor hesitated for only a second, then made up his mind to stay.

Zheng Ren didn't know about the professor's rich inner drama at all, he proofread the preoperative explanations one by one, and when the young woman came, Zheng Ren was still thinking about the various complications that might occur.

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

The young woman didn't care, in her words, this was the time for the family to do their best, and trouble the doctor to help.

And she has also done a good job of psychological construction, if she really can't get off the stage, she should suffer less.

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

Zheng Ren called the operating room to prepare for the operation, and then did not call Su Yun, and took the professor to the operating room.

Finally arrived at Zheng Ren's time, and Professor Rudolph kept asking the questions about the 3D reconstruction of 64-slice CT that had just come to mind.

Zheng Ren didn't bother to answer the professor's questions, lowered his head to change clothes, and only occasionally communicated with the professor.

All he could think about was the problems associated with embolization of the transverse lumbar artery surgery.

It is still necessary to go to the system operating room for training, and the experience of ten or twenty surgeries is enough.

Zheng Ren is now wealthy, and the new technique he came into contact with for the first time was ten or twenty attempts at random thought.

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

If this had been done before, I would never have dared to do it.

From simplicity to luxury, Si is reasonable.

After changing his clothes, Zheng Ren asked Professor Rudolph to make preoperative preparations, and he went to the small smoking room, lit a purple cloud, and entered the system space.

Purchasing 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, is divided into two terminal branches, anterior and posterior, on the anterolateral side of the intervertebral foramina.

The anterior ramus runs on the ventral side of the corresponding inferior border of the transverse process and the intertransverse ligament, and passes from the aponeurosis of the transverse abdominis muscle between the transverse abdominis muscle and the internal oblique muscle, supplying the posterior lateral abdominal wall tissue.

At the beginning of the issuance, a thin anterior branch of the foramen is sent out at the anterior edge of the foramen to the spinal canal to support the area anterior to the dura and the posterior vertebral body.

In the same position, the main trunk of the posterior branch sends outward inferior to the vegetative branch that enters the trunk of the lumbar plexus.

Embolization is required not only by the vegetative branch of the posterior branch that sends outward and descending into the lumbar plexus trunk, but also by the feeding blood vessels of the main trunk and the blood vessels of tumor tissue that are abnormally proliferated.

This was determined at noon when the 64-slice CT was reconstructed in 3D.

Because the patient has an advanced tumor, the surgery is also a palliative surgery to improve the quality of life, so it is necessary to avoid complications and try to embolize the blood vessels that supply the vertebral body.

Purely destructive surgery, it is not that difficult. In the past, this type of surgery did not do interventional embolization of the transverse lumbar artery, and the intraoperative bleeding should be 3000-5000 ml.

That's a daunting number.

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

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

Because Zheng Ren didn't want to just bolt off the main trunk of the posterior branch, in that case, although the operation was relatively simple, it could reach the level required by the imperial capital orthopedic professor.

However, the patient's intraoperative bleeding of about 1500 ml will still have a huge impact on the dying patient.

In order to improve the quality of life of patients, it is only right to have as little blood 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 ensure that the bleeding during surgery is minimized.

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

However, as a doctor, when there is a situation, I always want the patient to recover as soon as possible. If it cannot be cured, try to improve the quality of life during survival.

The spinal cord is extremely rich in blood vessels, except for the Adamchiviz artery, which should be avoided as much as possible, the other Zheng Ren also carefully imaged and found that there was no effect on other organs or the spinal cord, but simply supplied blood to the tumor, and then the plug was removed.

The operation proceeded very slowly, and Zheng Ren gradually mastered some corresponding embolization skills.

The level of grandmaster-level intervention is no joke.

Even so, after 10 surgeries, I was able to complete the embolization of the transverse lumbar artery every two hours.

To some extent, this kind of surgery is more difficult than prostate embolization to meet Zheng Ren's requirements.

After all, even if the prostate hyperplasia capillaries are ectopic 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 weakness, and an indwelling urethral catheter was sufficient.

This time, it is the arteries near the blood vessels that supply the spinal cord to be embolized.

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