Chapter 117 Big Accident

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

Protect your own children when they are angry. When being praised by others, be humble.

In Lao Director Pan's mind, Zheng Ren was his own child, the one who was very promising and loved.

"Super selection is well done." After watching for a few more minutes, Professor Pei said admiringly.

The micro-guide wire goes all the way from the hepatic artery to the next-level blood vessels. Difficulty, you can imagine.

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

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

It's a pity that people's calculations are not as good as heaven's. At the entrance of the hospital, the car that was picking up Professor Pei was hit, preventing the professor from being able to take the stage.

Although Professor Pei was not seriously injured, seeing that the operation could not be performed, and he certainly couldn't stay in Haicheng for too long, this promotion would inevitably end without a hitch.

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

But the turning point of the matter came to the young hospital chief in the emergency department of the city's first hospital.

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

Five minutes later, the superselection is over. According to the previous assumption, the micro-guide wire goes all the way from the femoral artery to the fourth-level blood vessels of the liver, and then advances 1cm to form the tumor.

The microcatheter begins to enter. Because the microcatheter is thicker and softer, a thin and hard guide wire should be used to designate a path, and then the microcatheter is sheathed over the guide wire and follows the superselected guide wire to reach the tumor. front.

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

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

Even if he came to power himself, he would probably be at this level. I didn't expect that there would be such a talent in this small place like Haicheng.

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

The Shay people understood, opened the heavy induction lead door, and entered the catheter operating room to start the preparation of chemotherapy drugs.

Because it is uncertain whether the operation will be successful or not, the chemotherapy drugs must be prepared now.

Liver cancer, unlike most cancers, has better first- and second-line chemotherapy drugs. It is a very special kind of cancer, and many years ago, there was no other way but to remove it surgically.

In the past ten years, interventional therapy has begun, and the successful development of targeted drugs such as sorafenib has given hope for the first-line rebirth of liver cancer patients.

However, according to the clinical research of the older generation of medical workers, a certain amount of chemotherapeutic drugs was injected while intervening and embolizing the blood vessels to support liver cancer, and the postoperative effect was better.

Think about it and know that chemotherapy drugs are all "poisons", and the principle is to fight poison with poison. After the embolization, go to the tumor to infuse chemotherapy drugs, and then plug the blood vessels. First, the tumor cells are soaked in the "poison", how can it have a little effect, and the second is that the feeding blood vessels are embolized, and there is no fresh blood supply, the tumor will lose nutrients.

The two-pronged approach works great.

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

Perfusion chemotherapy drugs, lipiodol embolization, step by step.

After doing all this, Zheng Ren started imaging.

The significance of this angiography is the same as the significance of flushing with warm saline after surgery, both to check whether there is any omission of surgery.

Professor Pei was very relaxed, and said with a smile: "I thought I was going to be super elected, but I didn't expect this little comrade to win it."

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

The angiographic images after the embolization were simultaneously displayed in front of Zheng Ren in the operating room and on the big screen in the operating room.

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

There is only one tumor in Zheng Yunxia's liver, but it is very large, with a diameter of about 8cm, which is almost half the height of the liver.

Angiography again showed that the lower half of the tumor had disappeared, which meant that the embolization was successful.

But!

The first half of the tumor is still there!

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

"Professor Pei, this is..." Although Director Pan recently made up his knowledge about intervention, he is already over 60, and his energy and memory are not as good as those of young people. In addition, there is no practical experience, so it is impossible to accurately judge what the situation is.

"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, but the upper half should come from outside the liver. Blood vessels supply blood."

"What could it be?" Director Pan asked.

"I don't know, the blood vessels in the whole body may supply blood to the tumor, which is the characteristic of tumor tissue." Professor Pei shook his head, his expression slightly heavy, "The most troublesome thing is that the spinal cord supply blood vessels branch off to feed the liver tumor. In that case, even if it is found and forcibly embolized, it is very likely that ectopic embolism will occur after surgery, resulting in paralysis of the patient.”

"..." Director Pan.

"..." Manager Feng.

"..." The Chu family sisters.

Only Xie Yiren blinked and couldn't see any worries at all. Maybe she had an inexplicable trust in Zheng Ren.

In her consciousness, there was no surgery that Mr. Zheng couldn't do.

"Of course, it's still good to be able to determine which blood vessel is feeding it. The difficulty lies in finding the feeding blood vessel, which requires luck." Professor Pei shook his head again.

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

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

"If you are not sure, end the operation now." Professor Pei looked directly at Zheng Ren's eyes behind the lead mirror, and said seriously: "Although it was not completely successful, it was a successful tumor reduction operation, which could improve the patient's survival. three to six months.”

Zheng Ren did not speak.

"Another option is to find the blood vessels that feed the upper half of the tumor, but that's difficult."

Of course, the Chu sisters and Xie Yi did not want to have only tumor reduction surgery. In the past few days, they have become friends with Zheng Yunxia. No matter from the perspective of friends or medical workers, they all hope to completely embolize the tumor.

But!

The operator of interventional surgery is exposed to part of the radiation exposure.

Although wearing lead clothing, if the operation time is short, the impact of this part can be offset by body functions. However, with the extension of the operation time, the operation has been under X-ray irradiation.

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

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

Everyone was silent.

Persuade Zheng Ren to continue?

Persuade Zheng Ren to give up surgery?

Dilemma!

"I'll try again." Without hesitation, Zheng Ren nodded and said firmly.

Thanks for the reward of Xi Baoer's reading time.
