"Not bad." Old Chief Physician Pan was happy to hear Professor Pei's praise.
He had to protect his own child when he was being bullied. It was better to be humble when praised.
In Old Chief Physician Pan's heart, Zheng Ren was his own child, the one who was very promising and doted on.
"Well done superselection," Professor Pei said appreciatively after a few more minutes.
The micro-guide wire went all the way from the hepatic artery to the next level of blood vessels. The further it went, the thinner it became, and the more difficult it was to go. Every superselection had to accurately enter the "correct" next level of blood vessels among several branches. The difficulty of this could be imagined.
Manager Feng's face was originally tense, and his expression was particularly ugly.
This was the first trial of his career. He had used almost all his resources to invite Professor Pei from Sorcery Capital just to make sure nothing went wrong.
Unfortunately, God's plan failed. Professor Pei's car had been hit at the entrance of the hospital, preventing him from performing the surgery.
Although Professor Pei was not seriously injured, he could not perform the surgery, and he certainly could not stay in Sea City for too long. The publicity campaign was bound to fail.
Manager Feng could imagine his future ending after a vigorous start and a quiet end.
However, the young chief resident of Sea City General Hospital's emergency department had turned the tide.
His initial worry and anxiety vanished with Professor Pei's acknowledgment.
Five minutes later, the superselection was completed. The guide wire traveled from the femoral artery to the fourth level blood vessel of the liver, one centimeter further to the tumor.
The microcatheter was inserted. Because it was thicker and softer, a thin and hard guide wire had to be used to designate a path. Then, the microcatheter was placed outside the guide wire and followed the superselected guide wire to the front of the tumor.
His movements were gentle and precise without the slightest mistake.
Professor Pei looked at the image attentively. Although he did not continue to praise Zheng Ren, his face was full of admiration.
Even if he were to perform the surgery himself, he would probably be at this level. He had not expected a small place like Sea City to have such a talent.
The microcatheter was pointed directly at the tumor. Su Yun turned off the imaging system and held the guide wire with his left hand. Xie Yiren understood and opened the heavy lead door.
Xie Yiren understood. She opened the heavy lead door and entered the operating theater to prepare the chemotherapy drugs.
Since the surgery was uncertain, the chemotherapy drugs had to be prepared on the spot.
Liver cancer was not like most cancers, where first-line and second-line chemotherapy drugs were more effective. It was a very special kind of cancer. Many years ago, there was no other way but to remove it by surgery.
In the past decade or so, interventional therapy had begun to appear. Coupled with the successful development of targeted drugs such as sorafenib, patients with liver cancer had a glimmer of hope.
However, according to the clinical research of the older generation of medical workers, when interventional embolization of the blood supply of liver cancer and injection of a certain amount of chemotherapy drugs, the postoperative effect was better.
It was easy to understand that chemotherapy drugs were all "poisons". The principle was to fight poison with poison. After the embolization, they would inject chemotherapy drugs into the tumor and block the blood vessels. Firstly, they would soak the tumor cells in the "poison", which would at least have some effect. Secondly, the blood vessels would be embolized. Without fresh blood supply, the tumor would lose nutrients.
The two-pronged approach was very effective.
Xie Yiren swiftly prepared the chemotherapy drugs and inserted them into the high-pressure injector. Then, she gave Zheng Ren a cheering gesture before turning around and leaving the interventional radiology room, closing the heavy lead door behind her.
Chemotherapy drugs were perfused, iodized oil was embolized, and everything was done according to plan.
Once everything was done, Zheng Ren began the angiography.
The purpose of this angiography was the same as postoperative irrigation with warm saline solution. It was to check for any missed surgery.
Professor Pei was relaxed and said with a smile, "I thought I'd have to perform the superselection, but this little comrade insisted."
"Thank goodness, thank goodness." Old Chief Physician Pan's smile bloomed like a flower.
After the embolization, the angiography image appeared in front of Zheng Ren's eyes and on the large screen in the operating theater.
Professor Pei's smile became slightly unnatural.
There was only one tumor in Zheng Yunxia's liver, but it was very large. It was about eight centimeters in diameter, almost half the height of the liver.
Another angiography showed that the lower half of the tumor had disappeared, which meant the embolization was successful.
But!
The upper half of the tumor was still there!
"Hiss …" Professor Pei's expression darkened.
"Professor Pei, this is …" Although Old Chief Physician Pan had crammed knowledge on interventional radiology recently, he was in his sixties after all. His energy and memory were not as good as a young man's. Moreover, he had no practical experience, so he could not accurately determine the situation.
"There's a deviation in the preoperative imaging data." Professor Pei pointed at the tumor image on the screen and said, "The lower half of the tumor is supplied by the hepatic artery, but the upper half should be supplied by blood vessels outside the liver."
"What could it be?" Old Chief Physician Pan asked.
"I don't know. It's a characteristic of tumor tissue that all blood vessels in the body can supply blood to the tumor." Professor Pei shook his head with a slightly solemn expression. "The most troublesome thing is that one of the blood vessels in the spinal cord is supplying blood to the liver tumor. If that's the case, even if we find it and forcefully embolize it, there's a high chance that the patient will be paralyzed after surgery. "
"…" Old Chief Physician Pan.
"…" Manager Feng.
"…" The Chu sisters.
Xie Yiren was the only one who blinked. She did not seem worried at all. Perhaps she had an inexplicable trust in Zheng Ren.
In her mind, there was no surgery that Chief Zheng could not perform.
"Of course, it's still good to be able to determine which blood vessel is supplying the tumor. The difficult part is to find the blood vessel, which will depend on luck. "Professor Pei shook his head again.
Soon, Zheng Ren appeared in the operating theater in a sterile surgical gown.
"Professor Pei, what do you think?" Zheng Ren asked curtly.
"If you're not confident, end the surgery now." Professor Pei stared into Zheng Ren's eyes behind the lens and said seriously, "Although it's not a complete success, it's still a successful tumor reduction surgery. It can increase the patient's survival by three to six months."
Zheng Ren did not say anything.
"The other option is to find the blood vessel supplying the upper half of the tumor, but that's difficult."
Of course, the Chu sisters and Xie Yiren did not want the tumor reduction surgery to be the only option. They had become friends with Zheng Yunxia over the past few days. Whether it was from the perspective of a friend or a medical professional, they all hoped to completely embolize the tumor.
However!
Interventional radiology surgeons had to endure a portion of the radiation.
Although they wore lead aprons, if the surgery was short, they could still use their bodily functions to offset the radiation. However, as the surgery dragged on, even a man made of steel would not be able to withstand the continuous X-ray exposure.
Standing for twelve hours in surgery and standing for twelve hours in interventional radiology were two completely different concepts.
Surgery might be tiring, but standing for twelve hours in interventional radiology was fatal!
Everyone was silent.
Persuade Zheng Ren to continue?
Persuade Zheng Ren to give up the surgery?
They were in a dilemma!
