Chapter 620
There was nothing to say about the previous surgery process. After seeing a few silhouettes, Zheng Ren was certain that the condition described by Professor Rudolf Wagner was still mild.
Dr. Mechal's three coronary arteries were basically blocked, and the myocardium was severely ischemic, relying entirely on capillaries to provide negligible blood supply.
Without the support of extracorporeal membrane lungs to exchange blood oxygen outside the body and reduce the load on the heart, it is estimated that Dr. Mehal would have died long ago.
In the coronary arteries, shadows of stents full of thrombus and calcified plates can be vaguely seen. Zheng Ren recalled what Professor Rudolf Wagner said, when the guide wire was pulled out, there was a thrombus hanging at the end.
Such a serious coagulation disorder, what should be done to make the patient recover?
Yes, in Zheng Ren's eyes, the old man lying inside with extracorporeal membrane lungs and various machines to keep the flame of life alive is not the one who won the Nobel Prize in Biology and Medicine at the Karolinska Institute of Medicine and Surgery in Stockholm. The old man of Jiuding.
he,
just a patient,
Just a patient who needs surgery.
"Boss... here, the whole wave is blocked... Is there any hope..." the professor said hesitantly.
"It should be possible to use rotational atherectomy. I'm thinking about other things." Zheng Ren said lightly.
Uh... the professor was taken aback.
Coronary atherectomy, or coronary atherectomy, or rotational atherectomy for short.
It refers to a surgical method that uses a Rotablator with ultra-high-speed rotation to grind atherosclerotic plaque and calcified tissue in the coronary artery into extremely fine particles, thereby eliminating the plaque in the blocked vessel lumen.
This surgical method was developed in the United States in the 1980s. After several phases of clinical trials, it was approved by the FDA in 1993 and officially became a surgical method for clinically solving vascular intima calcification and plaque.
"Boss, Dr. Mehar has type C..." the professor whispered, when Su Yun stepped on his foot, he was stunned and looked at Su Yun, "Brother Yun, what's wrong?"
"The boss is thinking about the next step, that is to say, there is nothing wrong with the rotational atherectomy. Don't say that the opening end plate of the C-type blood vessel is a contraindication to the rotational atherectomy. Don't consider any complications such as dissection and grinding leakage." Su Yun took a breath, and the black hair on his forehead fluttered.
Professor Rudolf Wagner was stunned.
Surgery, if you don't even consider contraindications, what should you consider?
Su Yun's monstrous smile is overwhelming.
"Fu Guier, what you should consider is how to convince the people here to let the boss perform surgery on Dr. Mehar." Su Yun said, "Instead of questioning the boss's surgical standards."
This ass was shot! The level goes straight to the sky!
The professor was dumbfounded. He looked at Su Yun stupidly, and fell into a state of bewilderment.
No wonder Brother Yun is the boss's assistant, and he can only be regarded as a peripheral assistant. Look at this level!
But... the professor had countless questions in his mind, but he couldn't ask them out. Speaking out, is it questioning the level of the boss?
But at this time, doubting is the response that human beings should have. Brother Yun is still awesome, so he doesn't question it at all.
The professor suddenly admires Su Yun, and he is the only one who can do this.
Do you want to trust your boss completely? This is the only question that the professor has been thinking over and over in his mind.
Although the situation is bad, but the professor still has a way, how can you impress the boss?
As a result, the Nobel Prize will be at your fingertips a few years later, although I am only the second author.
defeat……
Bah bah, the boss can't fail.
Professor Rudolf Wagner made a psychological suggestion to himself.
Learn from Brother Yun! You must study, I am a man who is going to win the Nobel Prize.
After weighing the pros and cons, the professor hesitated and made a final confirmation.
"Boss, Dr. Mechal's condition is extremely complicated. Do you think the possibility of the operation being successful?" Professor Rudolf Wagner bent down and asked in a low voice with great respect.
"Successful surgery is sure to be successful. What I am thinking about is what to do if the blockage occurs again in a short period of time after the operation. Elderly people have poor blood vessel elasticity, so they may not have the opportunity to undergo rotational atherectomy next time. Zheng Ren looked at the video on the computer intently, and replied calmly.
The boss is the boss, it really works!
The professor made up his mind that since the boss said it could be done, it would definitely work.
Recalling the first time I saw the surgical video of the interventional embolization of the prostate, recalling the first time I saw the boss performing the TIPS operation, recalling...
After countless reflections, the professor himself felt confident.
"Boss, think about it first. I'll contact Dr. Mehal for an operation." The professor gritted his teeth and said, he decided to push everything up, "It may not be possible, I will try my best."
"Go, go." Zheng Ren waved his hand, like chasing away a fly, and chased away Professor Rudolf Wagner.
This guy was so noisy that he interrupted his train of thought several times.
Zheng Ren concentrated on looking at the image data of the surgical angiography, and countless similar documents appeared in his mind. Comparing them one by one, Zheng Ren searched for a solution to Dr. Mechal's coronary artery and blood coagulation mechanism problems.
After a long time, a bold plan gradually took shape.
The professor hasn't come back yet, Su Yun is sitting on the side, playing with the phone, looking at the video from time to time.
Seeing that he has time, Zheng Ren immediately entered the system space and clicked on the surgery training.
The system operating room rose from the ground, and an experimental subject appeared in front of him.
It even has extracorporeal membrane lungs. Zheng Ren also admires the intelligent simulation of the system. It's been a long time since I came to do surgery training, and the temperament of the big pig's trotters still hasn't changed.
Only if you meet for the first time,
fine,
fine!
Zheng Ren immediately entered the system operating room and began to perform rotational atherectomy.
The images of Dr. Mechal's coronary angiography showed plaque formation at the branches of the starting points of the three coronary vessels, which is one of the contraindications to surgery.
The whole coronary artery is full of thrombus and plaque, which is one of the contraindications.
Of course, the so-called contraindications are only taboos at the current level of technology. Zheng Ren is someone who can covet peak surgery. These difficulties are nothing to Zheng Ren.
For example, the contraindication of angulation of blood vessel branches, 60° was a contraindication in the past. Now, it has been increased to 90° is the surgical taboo.
The level of technology is constantly improving, and the so-called contraindications are constantly changing.
But Zheng Ren's problem is that he only understands the theory, and he hasn't even done a single cardiac interventional surgery.
Let's train for a while, Zheng Ren estimates that it will take about five days of surgical training to complete.
Anyway, my family has a big business, and a few months of surgical training time is not bad.
Moreover, coronary surgery is also very important, and it is not a waste.
Zheng Ren calmed down and began the operation.
Coronary atherectomy uses an olive-shaped atherectomy head with diamond particles to selectively remove fibrous or calcified atherosclerotic plaques according to the principle of "selective cutting".
The surgery is performed delicately so as not to cut elastic tissue and normal coronary arteries.
The catheter is placed, the guide wire is entered, and surgical training begins.
