"Professor Zhou, how did this form?" Director Han couldn't understand either. He had been looking at the bone cement foreign objects like toothpicks and asked after a long time.

Zhou Congwen's surgery was done step by step, and the extracorporeal circulation had stopped and was observing whether there was any active bleeding.

"Due to improper operation during bone cement, the trocar pierced the paravertebral vein and formed traffic with it.

When the bone cement is still in a semi-fluid state, the bone cement overflows through the paravertebral venous system and enters the systemic circulation, and finally enters the right atrium, and then the cement solidifies in the heart cavity, forming a white toothpick-like foreign object of about 9m."

"Why is there no coagulation in the blood vessel?" Director Han continued to ask.

Zhou Congwen shrugged, "When the injection is inadequate polymerization of bone cement, the balloon dilates the vertebrae too much, the needle tract communicates with the paravertebrae vein, causing the bone cement to enter the paravertebrae vein and enter the systemic circulation."

"Once the bone cement enters the systemic circulation, even small emboli can be fatal after hardening. If these emboli stay in the right atrium or right ventricle, it may lead to heart perforation and heart tamponade, and may also enter the pulmonary circulation, leading to pulmonary artery embolism."

"What we see this time is only one of the various possible situations, and there is also the possibility of coagulation into emboli in the blood vessels."

"Oh, that's it." Director Han looked at 9CM's white toothpick and squinted his eyes. No one knew what he was thinking.

"A linear bone cement block of 10mm to 20mm can cause heart tamponade. Bone cement less than 10mm may enter the pulmonary circulation through the right heart system, causing pulmonary embolism. This... is also quite special. Bone cement of 9m is really rare."

"The problem this time is that the surgeon was too rough when he was drilling bone cement. He didn't notice that the needle tip penetrated the vein and pushed part of the bone cement into the body circulation."

"No, if someone comes up with this kind of medical accident, the orthopedics can kill people."

Zhou Congwen sighed.

If the orthopedics do it themselves, it would be fine. After the incident, it would be a technical accident, and it would not be a responsibility accident. The hospital will come forward to solve the problem and discuss a proper solution with the patient and the patient's family.

But the patient's surgeon... is actually a manufacturer's person. Even if he has a professional certificate, he can't say anything about it.

Director Xu lowered his head, and every word and every word in Zhou Congwen's ear slapped his face like a slap.

A snapping sound.

"The surgery should be done seriously, especially some unexpected situations. Bone cement... The surgery is relatively simple. Has no one gone out to study before?" Zhou Congwen asked.

"I went to France for a look, and all three major directors have been to France." Director Han said.

"Oh, I'll just play." Zhou Congwen smiled, "In fact, the short-term study arranged by this kind of manufacturer is not very meaningful, and local doctors don't know much about many complications."

"Let's do this, I'll give you a lesson after the surgery. Such a simple operation can actually happen such a big thing, it shouldn't be."

Director Han looked up and glanced at the three orthopedic directors.

"Thank you Zhou...Professor Zhou." Director Gu Yi's quick response.

Director Gu Er's director began to agree. Director Xu of Gu San was already in a deep state of confusion and chaotic state, unable to extricate himself. His sterile cap was wet with sweat, and his whole body seemed to be sleepwalking.

The 9m bone cement is like a nightmare, and it can't be pulled out even if it is stuck in his heart.

"Thank you for your hard work, Professor Zhou." Director Han said.

"In fact, the method to prevent and avoid similar complications is very simple. Add some contrast agent to the bone cement. When applying bone cement to the vertebrae, it is difficult to get into the hybrid operating table while watching."

Zhou Congwen gave a little detail.

"What if it penetrates?" Director Han asked.

"If the needle canal is found to communicate with the paravertebral venous system under fluoroscopy, reposition and stuff the gelatin sponge to compress the venous bleeding."

Zhang You stood opposite Zhou Congwen and kept bowing his head to concentrate on the operation. He performed more seriously, cautiously and cautiously than when he was an operator.

Moreover, he didn't say a word about the entire operation, and focused on assisting Zhou Congwen.

Although he didn't speak, Zhang You's heart was ups and downs and mixed feelings.

Zhou Congwen is very good. Zhang You already knew this when Geng Haoran's son had congenital heart disease surgery half a year ago.

Otherwise, he wouldn't have rushed to find Wang Chengfa, and he would either take in the incorporation or press him to death before Zhou Congwen's wings were hard.

But Zhang You knew that he made mistakes again and again, and underestimated Zhou Congwen again and again.

It’s not because I don’t pay enough attention to it, but because my knowledge and skills are limiting, and I can’t imagine any more things.

Zhou Congwen not only did the thoracoscopy well, but also did the thoracoscopy well;

Not only is the thoracoscopic surgery done well, but the percutaneous coronary intervention treatment is done just as well;

Not only are percutaneous coronary intervention surgery good, but the heart surgery level is also top-notch.

And he is now telling the orthopedic directors a minimally invasive surgery that belongs to orthopedics, which is very clear.

Things that I and others don’t understand become extremely simple in Zhou Congwen’s mouth.

"But don't worry, heart cement embolization caused by bone cement leakage is a rare life-threatening complication after vertebroplasty. Generally speaking, hundreds of surgeries may not happen once, and if contrast agent is used, thousands may not have an accident."

"Hahaha, I'll lend you Professor Ji Yanzhou." Director Han smiled, "You can tell me later. If you do a systematic training, I guess I will have very few opportunities to wipe their butts."

"It's really tiring to be the director of the medical department. Thank you for your hard work," Zhou Congwen said seriously and politely.

Zhang You was about to complain in his heart, but he stopped immediately.

He subconsciously worried that Zhou Congwen could "hear" the voice of his heart.

Why did Zhou Congwen insist on coming to the Second Hospital of Medical University? Isn’t it good to be a junior high school student or a junior high school student?

Zhang You felt the pressure was getting stronger and stronger.

Now he is surrounded by enemies and has long wanted to raise the flag to surrender.

The general chest atrophy was visible to the naked eye. If Zhou Congwen thought, he could have failed to perform surgery within three months.

The circulatory department and Zhou Congwen were wearing a pair of pants, MD! The old woman Tengfei actually wore a pair of pants with Zhou Congwen! Zhang You couldn't help it and whispered viciously.

Now it's better. Even Director Han trusts Zhou Congwen very much. Director Han doesn't believe in himself, but believes in Zhou Congwen, where he makes sense.

Can I have surgery in the future?

Yes! Zhang You cheered up himself.

Various valve lesions are sure to be OK!

A distracted person, Zhou Congwen's big tweezers hit Zhang You's hemostatic forceps.

"Director Zhang, do the surgery, concentrate."
