Unlike normal tumor tissue, what we have seen before is all part of the body. Although it is abnormal growth and has pathological changes, it is still a part of the body.
But the big watermelon in front of me seems to have its own independent circulation system. The stem is the pipe, constantly squirming... squirming...
Venous blood enters the heart, flows through the right atrium, enters the right ventricle, and then enters the pulmonary artery to participate in blood oxygen exchange.
After oxygen exchange, the blood enters the left atrium from the pulmonary veins, enters the left ventricle, and enters the ascending aorta.
This is the path for normal blood circulation in the heart.
The reason why Zheng Ren thought of this was because the beating of the big watermelon was inconsistent with the beating of the heart and was much faster.
If it were a living thing, it would be better if it was in the left ventricle, so it receives arterial blood and has more adequate "nourishment".
But it is in the right atrium and absorbs venous blood.
Could it be that this is an anaerobic organism that doesn't like oxygen
I don't know if it's because of the long-term soaking in blood, or it's just the way it is. The color of the big watermelon is dark red, and it feels like it's flat.
Zheng Ren gently placed his fingers on the big watermelon and determined the time it took for the test subject's heart to beat once. It would beat 4-5 times.
It's really a weird thing. I don't know if the big pig's hooves can perfectly simulate this guy.
According to the past surgical practice, the patient must be bluntly separated first to remove it from the right atrium with minimal damage, and then wait until the operation is completed before incision.
Putting the smallest hemostatic forceps on his fingers, Zheng Ren put on the microscope and started to dissociate the peripheral tissue.
Parting, pulling, lifting and pinching, the entire pedicle of the big watermelon was freed by Zheng Ren. The right atrium wall and the lateral wall intima of the inferior vena cava were dissociated and cut off together.
This is the principle of complete tumor resection, with normal tissue always surrounding the tumor. Otherwise, as long as there is a trace of tumor cells, recurrence is inevitable.
In Zheng Ren's opinion, this thing is completely tumor tissue, even more "malignant" than tumor tissue!
The tumor, the right atrium wall to which the tumor is attached, and part of the inferior vena cava lateral wall were completely removed, and the inferior vena cava cannulation was immediately switched. The control band was tightened and the surgical field was clear.
Zheng Ren then used autologous pericardial patch and inferior vena cava repair. I cut out two pieces of the pericardium and, like a tailor, sewed and mended the right atrium and inferior vena cava.
The simple thing is that the surgery box provided by Dr. Charles is complete with all kinds of equipment, and it can solve this problem without even using the smallest needle.
After continuous sutures and no active bleeding, Zheng Ren let out a sigh of relief.
The surgery comes to an end here.
As for suturing and so on, that is the assistant's job and has nothing to do with him as a surgeon.
The entire operation was much simpler than that for tricuspid valve tumors, and Zheng Ren successfully completed it in one go.
He didn't care about the test subject's chest, but came to the side, held the "big watermelon" in his hand, and observed it carefully.
Because there was no blood supply, the two straws moved significantly slower.
Zheng Ren felt that it was really sane, as if the "Big Watermelon" was communicating with him through sterile gloves.
It's a pity that I can't understand it.
That frequency is not Morse code, nor is it any other cryptosystem that Zheng Ren knows.
Let's cut it open and see. Zheng Ren holds the "big watermelon" in his left hand and cuts it with a knife in his right hand.
At the moment of incision, everything in front of Zheng Ren's eyes turned bright red, and then the system prompt appeared - the operation failed and the surgeon died.
The system operating room disappeared, and Zheng Ren stood alone in the system space, facing the ridicule of the little white fox on the other side of the pond.
What the hell is going on
Zheng Ren was dumbfounded.
If the operation fails, then it fails. Why is there a sudden reminder that the surgeon is dead
Time passed quickly. The first thing Zheng Ren did after he recovered was to continue buying surgery training time.
As the system operating room rose from the ground, he stepped directly in.
This time, the little beast in Zheng Ren's heart roared.
He knew that his guess was right. The space-occupying lesion in Chu Nuangse's right atrium was not myxoma at all, but worm eggs!
Just when I cut open the insect egg, the insect body inside came out and killed me.
What an alien!
The sudden change in painting style made Zheng Ren a little uncomfortable.
The reason why he maintains a respectful and distant attitude towards some things involving strange powers and chaotic gods is because Zheng Ren feels that these can be explained by science.
If you can't explain it, it's because the technology tree hasn't reached that level yet.
It is difficult to use one technology tree to explain the technology of another technology tree without reaching the peak.
Therefore, Zheng Ren is in awe, but stays away.
This is not your own world, nor is it your own technology tree.
However, when you come to Nanyang, you will inevitably come into contact with these weird things.
Zheng Ren looked at the surrounding environment and made sure it was the system space, not the outside.
This time he did not perform extracorporeal circulation and started dissection directly.
After opening the heart, Zheng Ren carefully made a small hole with a lancet, and then inserted the oval forceps.
Test subject, died.
Zheng Ren used oval forceps to clamp randomly, and finally made sure that everything was fine, and then dissected the right atrium of the test subject.
There was a lot of bleeding inside, and a thin thread-like worm was crushed and mixed with other messy tissues.
This time Zheng Ren was fine. The system did not prompt the surgeon to die, but the operation failed.
Zheng Ren was sure that it must be the problem of this little bug that caused the strange reminder that the magician had died.
He stabilized his mind and performed another operation, but this time he only performed the operation honestly and did not touch the "big watermelon".
The surgery completion rate is 95%.
For an extremely complex operation, Zheng Ren completed it by himself. It is already good that the system can give such a high evaluation.
Back to reality, Zheng Ren heard the sound of a flat car coming from the corridor.
The quality of the flat car is good, better than those of Haicheng and 912. The ground is also flat and the sound is very small.
Although this is called a national hospital, it is an out-and-out private hospital. All kinds of equipment are prepared for rich people, regardless of cost.
To be honest, Zheng Ren was a little envious.
"Su Yun, Lao He, you guys prepare first, I'll go explain something to the patient's family," Zheng Ren said.
"Hey, why are you sneaking around again?" Su Yun was obviously dissatisfied with Zheng Ren's actions, nagging.
Zheng Ren looked at Xie Yiren carefully and forced a smile. Fortunately, I was in the operating room, wearing a sterile mask, so I couldn't tell how forced my smile was.
Xie Yiren smiled back, and Zheng Ren felt that the world now was very warm.
Walking out of the operating room, Zheng Ren saw Chu Nuangsai half-siting on a flat car, with more than a dozen doctors and nurses pushing him over.
"Wait a moment, Mr. Chu Nuangsai, I have something to tell you." Zheng Ren stood in front of the flat car and blocked the way.
