Dr. Charles Moore nodded. He was a little tired due to the illness. Instead of putting on a pair of sterile gloves and continuing the dissection with Zheng Ren, he turned around, waved his hand, and returned to his seat.
Zheng Ren knows that coronary artery ectasia is rare, and there is no particularly good way to treat it. Interventional stent is one method.
But Dr. Charles Moore is at the Mayo Clinic, which is known as the world's number one hospital in cardiac treatment. There is no reason why he can remove a stent but cannot.
The condition is a bit confusing, because the system panel is only light red, so the situation is probably not serious. What troubles Dr. Charles Moore may be stable angina.
This type of angina is the same as angina caused by myocardial ischemia, but it is not fatal.
Zheng Ren was a little curious. The old man's dissection technique was the most exquisite he had ever seen. The previous discussion seemed to have opened a new door, so Zheng Ren wanted to ask about the specific situation.
After taking off his gloves, before Zheng Ren could say anything, a man hurried in.
"Dr. Zheng, why are you here?" Professor Danilo Acosta said.
Zheng Ren smiled and asked, "Have the preoperative preparations been completed?"
"It's done. If your time permits, you can start the operation at any time." Danilo's words were more polite, but his expression betrayed his truest thoughts.
He was very impatient, very impatient.
"Speak lower," scolded Dr. Charles Moore's assistant.
Danilo rushed in in a hurry and didn't notice who was sitting inside. He had not slept all night, was exhausted mentally and physically, and had a bad temper. He would curse at others if he turned his head.
However, when he saw Dr. Charles Moore, all the anger on his face seemed to be blown away by the strong wind, and he said gently and humbly: "Hello Dr. Charles, why are you here?"
"What kind of surgery?" Dr. Charles Moore asked in a low voice with his eyes closed and his brows slightly furrowed.
"While studying nephrogenic hypertension, some problems arose. We consulted Dr. Zheng, and he thought surgery was possible. After... "
"Is it the issue of percutaneous radiofrequency ablation of renal sympathetic nerves?" Dr. Charles Moore asked.
"Yes, yes." Danilo replied immediately.
"Oh, look, I said interventional surgery has no future." Dr. Charles Moore opened his eyes slightly, glanced at Zheng Ren, and asked, "What happened? How are you going to deal with it?"
"I judge that the process of radiofrequency ablation caused the fusion of the renal sympathetic nerve and the renal artery, combined with renal artery stenosis, resulting in the patient's resistant hypertension." Zheng Ren said with a smile: "A dissection operation is performed, and then the lower renal artery stent is removed. That’s it.”
Dr. Charles Moore did not say this time that there was no future for interventional surgery. Instead, he thought about it and said, "You guys go to the surgery first. I'll go take a look later."
Danilo was relieved to hear Dr. Charles say this.
After coming out of the lecture theater, Su Yun felt a little strange and asked the professor: "Why do I feel that Dr. Charles is biased against interventional surgery?"
Professor Rudolf Wagner smiled helplessly, but his smile was stiff and finally turned into a sigh.
"Stop pretending, say it quickly." Su Yun was unhappy.
"Brother Yun, Dr. Charles Moore diagnosed coronary atherosclerotic heart disease 9 years ago and performed stent surgery. However, problems occurred after the operation, and the symptoms of angina pectoris never eased," the professor explained.
When Zheng Ren heard this, his heart moved and he asked, "Is it complicated by coronary artery ectasia after surgery?"
"Yes." the professor replied.
As an interventional doctor with ambitions for the Nobel Prize, he secretly called Charles a devil. How could the professor not know this
Su Yun glanced at Zheng Ren with disdain. This guy said he had no interest in the Nobel Prize, but in fact he did some research on the relevant people in private. Otherwise, if he didn't know such a thing, how would he know that Dr. Charles Moore had coronary artery ectasia after surgery.
"That's such a pity, but there is no possibility of sudden death due to myocardial ischemia. Just monitor whether an aneurysm will form." Zheng Ren said casually.
"Aneurysms are easily formed. The degradation and loss of elastic fibers in the middle layer of coronary blood vessels are considered to be the central link in the disease. However, there are many causes. It is difficult to find a definite cause and treat it." Su Yun said about heart diseases He learned about it in detail, and even though it was a rare disease, he explained it casually.
"That's right." Zheng Ren nodded and said, "Although the problem can usually be solved with a stent, Mayo has been slow to do so. I suspect there will be more trouble."
"I don't recommend it. Dr. Charles Moore is an elderly patient and has lost the elastic fibers in the middle layer of the coronary arteries. The coronary arteries are very thin and fragile. If there is no aneurysm, he still recommends conservative treatment."
Zheng Ren knew that what Su Yun said was right, and it was a thought shared by most doctors.
Coronary ectasia without aneurysm is not fatal. The only trouble is the need to take warfarin for a long time and the problem of stable angina.
It's just painful. Compared with risky surgery, conservative treatment is better.
But this also explains why Dr. Charles Moore is biased against interventional surgery.
The coronary stent was inserted, but a rare coronary artery ectasia developed. Anyone else would have a strong sense of distrust in interventional surgery.
But this matter had nothing to do with Zheng Ren, and he didn't want to get involved in such troublesome treatment. Su Yun is right, all surgeries for elderly patients must be done with caution, otherwise the surgery will go wrong and they will face countless troubles.
Returning to the nephrogenic hypertension laboratory, there are many people here, each busy. It is completely different from the situation in the early morning when there are only two doctors and two nurses working the night shift here.
This is the real Mayo Clinic, Zheng Ren thought to himself.
Professor Rudolf Wagner and Su Yun were responsible for handling various pre-operative document procedures, and Zheng Ren did not pay attention to their communication.
Although he has the passive skill of language proficiency, Zheng Ren is still not interested in interpersonal communication and only wants to perform surgery.
Looking at the patient lying inside through the transparent glass, the blood pressure is very high, and this is even under the premise of pumping antihypertensive drugs.
There seems to be no special change in the situation, Zheng Ren thought to himself.
Then give it a try. He immediately entered the system space, exchanged for surgical training, and began the last simulated surgery before surgery.
The operation went smoothly. After all, Zheng Ren had simulated it many times and found the most basic cause.
Looking at the evaluation of 98% completion of the operation, Zheng Ren was still very satisfied.
