"It's quite skilled. Director Pan was very happy to hear Professor Pei praise Zheng Ren.

Your own children should be protected when they are angry. When you are praised by others, you should still be humble.

In Director Pan's heart, Zheng Ren is the child of his own family, and he is still the one who is very promising and favored.

"Well done for superselection. After looking at it for a few more minutes, Professor Pei said appreciatively.

The micro-guidewire enters the next level of blood vessels from the hepatic artery all the way, and the thinner and thinner it goes, the more difficult it becomes, and each overselection must accurately enter the "correct" next level of blood vessels in several branches, which is difficult and can be imagined.

Manager Feng originally had a stiff face, and his face was particularly ugly.

This was the first trial in his career, and he used almost all his resources to invite Professor Pei from the magic capital, in order to be foolproof.

It's a pity that people are not as good as heaven, and at the gate of the hospital, the car that picked up Professor Pei was hit, causing the professor to be unable to go on stage.

Although Professor Pei was not too seriously injured, seeing that the operation could not be done, and he certainly could not stay in Haicheng for too long, this publicity and promotion would inevitably end without a problem.

With a vigorous start and a quiet end, Manager Feng can think of his future ending.

But the turning point came when the young inpatient general in the emergency department of the city's first hospital turned around.

The initial worry and anxiety turned into nothingness with Professor Pei's approval.

Five minutes, the overselection is over, and the microguidewire enters the fourth-level blood vessels of the liver from the femoral artery all the way to the liver according to the previous assumption, and then advances 1cm to the tumor.

The microcatheter begins to enter, and because the microcatheter is thicker and softer, a path is designated with a thin, rigid guidewire, and then the microcatheter is placed outside the guidewire and followed the super-selected guidewire straight to the front of the tumor.

The movements are gentle and precise, without the slightest mistake.

Professor Pei looked at the image intently, and although he did not continue to praise Zheng Ren, his face was full of appreciation.

Even if he came to power, it is estimated that it will be at this level, but I didn't expect that there would be such a talent in this small place as Haicheng.

The microcatheter was directly aimed at the tumor, Su Yun turned off the imaging system, held the second half of the microguidewire and the microcatheter with his left hand, raised his back hand, and said hello.

The Shay man understood, opened the heavy induction lead door, entered the catheterization operating room, and began to prepare chemotherapy drugs.

Because it is uncertain whether the surgery will go smoothly or not, the chemotherapy drugs must be prepared immediately.

Liver cancer, unlike most cancers, has first- and second-line chemotherapy drugs that work well. It is a very special type of cancer, and many years ago, there was no other way to remove it than surgery.

In the past ten years, interventional therapy has begun to be available, coupled with the successful development of targeted drugs such as sorafenib, which has given liver cancer patients hope for rebirth.

However, clinical studies by the older generation of medical workers have shown that while intervening to embolize the blood vessels of liver cancer, a certain amount of chemotherapy drugs is injected into the postoperative effect.

If you think about it, you also know that chemotherapy drugs are all "poisons", and the principle is to fight poison with poison. At the end of the embolization, the tumor is perfused with chemotherapy drugs, and then the blood vessels are blocked, one is to soak the tumor cells in the "poison", how can it have a little effect, and the other is that the feeding blood vessels are embolized, there is no fresh blood supply, and the tumor will lose nutrients.

It's a two-pronged approach that works great.

Shay moved quickly, quickly prepared chemotherapy drugs, installed them on the high-pressure syringe, and then made a cheering gesture to Zheng Ren, turned around and left the interventional operating room, closing the heavy lead door.

Perfusion of chemotherapy drugs, iodized oil embolization, step by step.

After doing all this, Jung in began to make films.

The significance of this imaging is the same as that of irrigation with warm saline after surgery, both to check for any omissions in surgery.

Professor Pei was very relaxed and said with a smile: "I thought I was going to be on the stage to be over-elected, but I didn't expect this little comrade to want it." ”

"It's okay, it's okay. Director Pan's face turned into a flower.

The imaging images after the embolization were synchronized in front of Zheng Ren's eyes in the operating room and on the large screen in the operation room.

Professor Pei's smile just now became a little unnatural.

Zheng Yunxia has only one liver tumor, but it is very large, about 8cm in diameter, almost half the height of the liver.

Re-imaging showed that the lower part of the tumor had disappeared, which meant that the embolization was successful.

But!

The upper half of the tumor is still there!

"Hiss......" Professor Pei's face became heavy.

"Professor Pei, this is ......" Although Director Pan has recently made up for his knowledge about intervention, he is already in his sixties after all, and his energy and memory are not as good as those of young people. In addition, I have no practical experience, so I can't accurately judge what the situation is.

"There was a discrepancy in the preoperative imaging data. Professor Pei pointed to the tumor image on the big screen and said: "The blood vessels in the lower part of the tumor are supplied by the hepatic artery branch, but the upper part should be supplied by blood vessels outside the liver. ”

"What could it be?" asked Director Pan.

"I don't know, the blood vessels of the whole body have the potential to supply blood to the tumor, which is the characteristic of the tumor tissue. Professor Pei shook his head, his expression was slightly heavy, "The most troublesome thing is that the spinal cord is divided into blood vessels to feed liver tumors. In that case, even if it is found and forcibly embolized, there is a high risk of ectopic embolism after surgery, resulting in paralysis of the patient. ”

"......" Director Pan.

"......" Manager Feng.

"......" Chu family sisters.

Only Shay blinked, unable to see any concern at all, perhaps she had an inexplicable trust in Zheng Ren.

In her consciousness, there is no operation that Mr. Zheng can't do.

"Of course, it's good to be able to tell which blood vessel is supplying. The challenge is finding the blood vessels that are sustening, and that's where luck comes in. Professor Pei shook his head again.

Soon, Zheng Ren appeared in the operation room wearing a sterile surgical gown.

"Professor Pei, what do you think?" Zheng Ren said very succinctly.

"If you're not sure, end the operation 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 also a successful debulking operation, which can improve the survival of patients by three to six months." ”

Jung in didn't speak.

"Another option is to find a blood vessel for the upper half of the tumor, but it's difficult. ”

Of course, the Chu family sisters and Shay people don't want to only have tumor reduction surgery, and in the past few days, they have become friends with Zheng Yunxia. From the perspective of friends and medical workers, they want to completely embolize the tumor.

But!

Interventional surgeons are exposed to a portion of radiation.

Even if you are wearing a lead suit, if the surgery is short, you can use your body to counteract this part of the image. However, as the operation time was prolonged, the operation was always under X-ray irradiation, and the iron beating people couldn't stand it.

Surgery, 12 hours and 12 hours for interventional surgery, are very different concepts.

Surgery may be tiring, but 12 hours of interventional surgery can be deadly!

Everyone was silent.

Persuade Zheng Ren to continue to do it?

Persuade Jeong-in to give up surgery?

In a dilemma!

"I'll try again. Zheng Ren did not hesitate, nodded, and said firmly.
