"Quite proficient." Director Pan was very happy to hear Professor Pei praise Zheng Ren.
Protect your own children when they are angry. When you are praised by others, you still have to be humble.
In Lao Director Pan's heart, Zheng Ren was his own child, the one who was very promising and loved.
"Super Selection is well done." After watching it for a few more minutes, Professor Pei said with appreciation.
The microguidewire enters all the way from the hepatic artery to the next-level blood vessel. It becomes thinner and more difficult as it goes. Each super-selection must accurately enter the "correct" next-level blood vessel among several branches. Among them, The difficulty can be imagined.
Manager Feng had a sullen face and looked particularly ugly.
This was the first trial in his career, and he spent almost all his resources to invite Professor Pei from the Demon City in order to be foolproof.
Unfortunately, fate is not as good as fate. At the entrance of the hospital, the car picking up Professor Pei was hit, causing the professor to be unable to go on stage.
Although Professor Pei was not seriously injured, it seemed that the operation could not be performed, and he certainly could not stay in Haicheng for too long. This promotion would inevitably end in vain.
It started vigorously and ended quietly. Manager Feng could only think of his own ending in the future.
But things took a turn for the better when the young resident in the emergency department of the city's first hospital.
The initial worry and anxiety disappeared with Professor Pei's approval.
Five minutes later, the superselection was completed. The microguidewire entered from the femoral artery all the way into the fourth-level blood vessels of the liver according to the previous idea. After advancing 1cm, the tumor was found.
The microcatheter begins to enter. Because the microcatheter is thicker and softer, a thin and hard guidewire is used to designate a path. Then the microcatheter is placed outside the guidewire and follows the superselected guidewire directly to the tumor. ahead.
The movements were gentle and precise, without any mistakes.
Professor Pei looked at the image intently. Although he did not continue to praise Zheng Ren, his face was full of appreciation.
Even if he came on stage, he would probably be at this level. I didn't expect that a small place like Haicheng would be full of talents like this.
The microcatheter was directly facing the tumor. Su Yun turned off the imaging system and held the microguidewire and the second half of the microcatheter with his left hand. He raised his back hand and said hello.
Xie Yiren understood, opened the heavy induction door, entered the catheter operating room and began to prepare chemotherapy drugs.
Because we were not sure whether the surgery would go smoothly, the chemotherapy drugs had to be prepared on hand.
Liver cancer, unlike most cancers, has first- and second-line chemotherapy drugs that are relatively effective. It is a very special kind of cancer, and many years ago there was no other option but to surgically remove it.
In the past ten years, interventional treatments have begun to be available, and the successful development of targeted drugs such as sorafenib has given patients with liver cancer a glimmer of hope for rebirth.
However, clinical research by the older generation of medical workers has shown that while interventional embolization of liver cancer feeding blood vessels and injecting a certain amount of chemotherapy drugs can achieve better postoperative results.
If you think about it, you will know that chemotherapy drugs are all "poisons". The principle is to fight poison with poison. After embolization, chemotherapy drugs are injected into the tumor, and then the blood vessels are blocked. On the one hand, soaking the tumor cells in the "poison" can have some effect, and on the other hand, the feeding blood vessels are embolized and without fresh blood supply, the tumor will Lose nutrients.
A two-pronged approach works well.
Xie Yiren moved quickly and quickly prepared the chemotherapy drugs and installed them on the high-pressure syringe. Then he made an encouraging gesture to Zheng Ren, turned around and left the interventional operating room, and closed the heavy lead door.
Infusion of chemotherapy drugs, lipiodol embolization, step by step.
After doing all this, Zheng Ren started taking pictures.
The significance of this angiography is the same as that of flushing with warm saline after surgery, both to check whether there are any omissions in the surgery.
Professor Pei was very relaxed and said with a smile: "I originally thought I was going to be in the super election, but I didn't expect this little comrade to insist on winning."
"It's okay, it's okay." Old Director Pan's smile turned into a flower.
The contrast-enhanced images after the embolization were completed appeared simultaneously in front of Zheng Ren's eyes in the operating room and on the large screen in the operating room.
Professor Pei's smile just now was a little unnatural.
Zheng Yunxia only had one liver tumor, but it was very large, about 8cm in diameter, almost half the height of the liver.
Another angiogram showed that the lower half of the tumor had disappeared, which meant that the embolization was successful.
But!
The upper part of the tumor is still there!
"Hiss..." Professor Pei's face became serious.
"Professor Pei, this is..." Although old Director Pan has been supplementing his knowledge about intervention recently, he is already over sixty after all, and his energy and memory are not as good as those of young people. In addition, there is no actual operation experience, so it is impossible to accurately judge what is going on.
"There is a deviation in the preoperative imaging data." Professor Pei pointed to the tumor image on the big screen and said: "The feeding blood vessels in the lower half of the tumor are supplied by the hepatic artery branches, but the upper part should come from outside the liver. Vessels supply blood.”
"What could it be?" Old Director Pan asked.
"I don't know. Blood vessels throughout the body may supply blood to tumors. This is a characteristic of tumor tissue." Professor Pei shook his head, his expression slightly heavy. "The most troublesome thing is that the spinal cord feeding blood vessels branch off to supply liver tumors. . In that case, even if it is found and forced embolization is performed, ectopic embolism is likely to occur after surgery, causing the patient to be paralyzed."
"..." Old Director Pan.
"..." Manager Feng.
"..." Chu family sisters.
Only Xie Yiren blinked, not showing any worry at all. Maybe she had an inexplicable trust in Zheng Ren.
In her mind, there was no operation that Mr. Zheng couldn't perform.
"Of course, it would be good to be able to determine which blood vessel is supplying the blood. The difficulty lies in finding the supplying blood vessel, which requires luck." Professor Pei shook his head again.
Soon, Zheng Ren appeared in the operating room wearing sterile surgical clothes.
"Professor Pei, what do you think?" Zheng Ren said simply.
"If you are not sure, end the surgery now." Professor Pei looked directly into Zheng Ren's eyes behind the lead mirror and said seriously: "Although it was not completely successful, it was still a successful tumor reduction surgery and can improve the patient's survival. The period is three to six months.”
Zheng Ren said nothing.
"Another option is to find the feeding blood vessels in the upper half of the tumor, but this is difficult."
Of course, the Chu sisters and Xie Yiren did not want to just undergo tumor reduction surgery. In the past few days, they had become friends with Zheng Yunxia. Whether from the perspective of friends or medical workers, they all hope that the tumor can be completely embolized.
But!
The surgeon who performs interventional surgery must bear some radiation exposure.
Even though you are wearing a lead suit, if the operation time is short, you can still use your body functions to offset this part of the image. However, as the operation time prolongs and the operation is continued under X-ray irradiation, even a hard-core person cannot bear it.
Surgery, standing for 12 hours, and interventional surgery, standing for 12 hours, are completely different concepts.
Surgery may be tiring, but 12 hours in the interventional surgery station can kill someone!
Everyone was silent.
Advise Zheng Ren to continue
Advise Zheng Ren to give up the surgery
Dilemma!
"I'll try again." Zheng Ren nodded without hesitation and said firmly.
