There was nothing much to say about the previous surgery. After looking at a few silhouettes, Zheng Ren was certain that the condition described by Professor Rudolf Wagner was still mild.
Dr. Mehar's three coronary arteries were basically blocked, and his myocardium was severely ischemic, relying entirely on capillaries to provide a negligible blood supply.
Without the support of the extracorporeal membrane lung to exchange blood oxygen outside the body and reduce the load on the heart, Dr. Mehar would probably have died long ago.
In the coronary arteries, you can vaguely see the shadow of a stent filled with thrombus and calcified plates. Zheng Ren recalled Professor Rudolf Wagner's statement that when the guide wire was withdrawn, there was a blood clot hanging at the end.
How can the patient recover from such a severe coagulation disorder
Yes, in Zheng Ren’s eyes, the old man lying inside using extracorporeal membrane lungs and various machines to keep the flame of life from extinguishing was not the one who received the Nobel Prize in Biology and Medicine from the Caroline Institute of Medicine and Surgery in Stockholm. The old man of Jiuding.
he,
Just a patient,
Just a patient in need of surgery.
"Boss... here, the entire wave is blocked... Is there still hope..." the professor said hesitantly.
"It should be possible to use rotational atherectomy. I'm thinking about other things." Zheng Ren said calmly.
Uh... The professor was startled.
Rotational intimal coronary atherectomy, also known as rotational atherectomy, or rotational atherectomy for short.
It refers to a surgical method that uses a rotator with ultra-high-speed rotation to grind atherosclerotic plaque and calcified tissue in the coronary arteries into extremely fine particles, thereby eliminating the plaque blocking the vascular cavity.
This surgical method was developed in the United States in the 1980s. After several clinical phases, it was approved by the FDA in 1993 and officially became a clinical surgical method to solve the problem of intimal calcification and plaque in blood vessels.
"Boss, Dr. Mehar has a C-type..." the professor whispered. Su Yun stepped on his foot. He was startled and looked at Su Yun, "Brother Yun, what's wrong?"
"The boss is thinking about the next step, which means that there is no problem with rotational atherectomy. Don't pull the open end plate of the C-shaped blood vessel. It is a contraindication for rotational atherectomy. Don't consider complications such as dissection and leakage." Su Yun blew a breath, and the black hair on his forehead was floating.
Professor Rudolf Wagner was stunned.
If you don’t even consider the contraindications for surgery, what should you consider
Su Yun's evil smile captivated the country.
"Fuguier, what you should consider is how to convince the people here to let the boss perform surgery on Dr. Mehar." Su Yundao said: "Instead of questioning the boss's surgical skills."
This is a flattering shot! The level is sky-high!
The professor was dumbfounded and looked at Su Yun coldly, falling into a state of confusion.
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. By saying this, are you questioning the boss's level
But at this time, questioning is the reaction that humans should have. Brother Yun is still awesome and doesn't question it at all.
The professor suddenly admired Su Yun so much. He was the only one who could do so.
Do you have to trust your boss completely? The professor was thinking about this question over and over in his mind.
Although the situation is bad, the professor still has a way to defeat the boss
Success, the Nobel Prize will be within reach in a few years, although I am only the second author.
defeat…
Bah, the boss can't fail.
Professor Rudolf Wagner gave himself psychological suggestions.
Learn from Brother Yun! You must study, you are a man who wants to win the Nobel Prize.
After weighing the pros and cons, the professor felt relieved and made the final confirmation.
"Boss, Dr. Mehar's condition is extremely complicated. Do you think the operation is likely to be successful?" Professor Rudolf Wagner bent down and asked in a low voice with great respect.
"The operation will definitely be successful. What I am thinking about is what to do if the blockage occurs again within a short period of time after the operation. The elasticity of blood vessels in the elderly is very poor, so they may not have the opportunity to undergo rotational atherectomy next time. "Zheng Ren looked at the images on the computer intently and replied calmly.
The boss is just a boss, he can really do it!
The professor decided that since the boss said it could be done, it must be done.
I think back to the first time I saw the surgical video of prostate interventional embolization. I think back to the first time I saw my boss doing tips surgery. I think back...
After countless reflections, the professor himself felt confident.
"Boss, please think about it first. I will contact Dr. Mehar to perform surgery." The professor gritted his teeth and decided to put everything on the line. "It may not be possible, but I will try my best."
"Go on, go on." Zheng Ren waved his hand, shooing Professor Rudolf Wagner away like a fly.
This guy was so noisy that he interrupted his train of thought several times.
Zheng Ren concentrated on looking at the imaging data of the surgical angiography, and countless similar documents appeared in his mind. Comparing one by one, Zheng Ren looked for a solution to Dr. Mehar's coronary artery and coagulation mechanism problems.
After a long time, a bold plan gradually took shape.
The professor hadn't come back yet, so Su Yun sat aside, fiddling with his phone and looking at the video from time to time.
Seeing that he had time, Zheng Ren immediately entered the system space and clicked on surgical training.
The system operating room rose from the ground, and an experimental subject appeared in front of us.
There is even an extracorporeal membrane lung, and Zheng Ren admires the system's intelligent simulation. It's been a while since I've been to surgery training, and the temperament of Big Pig Hoof has not changed.
If we meet for the first time,
fine,
fine!
Zheng Ren immediately entered the system operating room and began to perform rotational atherectomy.
Dr. Mehar's coronary angiography images showed plaque formation at the branches at the origin of the three coronary vessels, which is one of the contraindications for surgery.
The coronary arteries are full of thrombus and plaque, which is another contraindication.
Of course, the so-called contraindications are only taboos under the current technical level. Zheng Ren is someone who can already covet the peak surgery. In Zheng Ren's view, these difficulties are not a problem.
For example, there is a contraindication for the angle of blood vessel branches. In the past, 60° was a contraindication. Nowadays, it has increased to 90°, which is a contraindication for surgery.
The level of technology is constantly improving, and the so-called contraindications are constantly changing.
But Zheng Ren's problem was that he only understood the theory and had never performed even one 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 is not enough.
Moreover, coronary surgery is also very important and is not a waste.
Zheng Ren calmed down and started the operation.
Coronary artery rotational atherectomy uses an olive-shaped rotational atherectomy head with diamond particles to selectively remove fibrotic or calcified arteriosclerotic plaques based on the principle of "selective cutting".
The surgery needs to be done very delicately so as not to cut into the elastic tissue and normal coronary arteries.
The catheter is inserted, the guidewire is inserted, and surgical training begins.
