Pulmonary artery embolism, also known as pulmonary infarction.

It refers to a clinical condition in which endogenous or exogenous embolic blocks the pulmonary artery or its branches and causes pulmonary circulation disorders.

The main source is thrombosis, and others include amniotic fluid embolism, fat embolism, air embolism, foreign body embolism, etc.

For example, amniotic fluid embolism is a very serious complication after caesarean section. It cannot be treated with thrombolysis. It was almost unsolvable ten years ago.

One of the most feared complications of orthopedic surgery is fat embolism.

After the patient develops pulmonary artery embolism, he will suffer from severe pain in the front, chest and back, and symptoms of difficulty breathing.

However, early patients generally feel that if they endure it, they will pass, which will delay the best treatment time.

But even when you arrive at the hospital, when the symptoms are atypical in the earliest stages, the embolization site is not as typical as this patient, and it is easy to miss the diagnosis.

Judging from the film, there is nothing to doubt, it is the thrombosis originating from the pulmonary artery valve that blocks the main trunk of the pulmonary artery.

Even the thrombus cannot be removed, and the grinding operation... the blood vessel wall is too thin, completely different from the coronary artery. In addition, it originates from the pulmonary valve, and the emboli on the valve cannot be treated.

Grinding surgery is impossible.

Zheng Ren's first impression is the same as many directors of 912, and he believes that patients can only be treated with thrombolysis.

But when his eyes were about to move away from the image, Zheng Ren stopped his eyes again.

In an instant, the vestibular nerve trembled violently, which was so uncomfortable.

It was like a roller coaster ride in a moment.

Realizing that Zheng Ren was wrong, Director Wei asked, "Boss Zheng, are you a little tired after a day of trouble?"

"No, there is something wrong with the film." Zheng Ren said as he looked at the film with his eyes straight.

"Hmm?" Director Wei was puzzled.

The image is very typical. The hospital consulted and no one had any objections to the diagnosis. There were slight differences, but there were some differences in treatment.

"Wait a minute, I'll think about it." Zheng Ren said, and then began to use the reconstruction ability.

Images at this location, three-dimensional reconstruction, nuclear magnetic enhancement, and vascular CTA are of no use.

Based on the most basic imaging data, Zheng Ren used dual-energy CT reconstruction mode to start re-observing the lesions originating from the pulmonary valve.

The dual-energy CT system can use two different energy X-rays to image objects, which can accurately obtain the composition ratio of objects.

Its principle was proposed in the 1970s.

The composition of the object can be accurately calculated by penetrating the stage through two photon beams of different energies through the stage, and the differences in energy absorption curves of different matters can be used to accurately calculate the composition of the object.

Of course, to be very close to the truth, the doctor who reads the film needs to have a very in-depth understanding of the image.

And Zheng Ren is this person.

Rebuilding ability is very handy. However, Zheng Ren felt it was a bit difficult to do dual-energy CT.

The brain is fully powered, like a machine, with constant roar. The CPU quickly processes various data, and Zheng Renluo is a little overwhelmed.

But dual-energy CT images are still established.

It is a bit blurry, and it is still different from the images made by a standard machine. Even so, Zheng Ren feels that it is enough.

Another situation is displayed on the image, which is completely different from the previous judgment.

There are not thromboembols in the large area of ​​filling defects near the pulmonary valve!

It is not a thrombus, but an echo of abnormal body tissue.

Zheng Ren looked at the dual-energy CT images that were added to his mind, and was instantly excited and suddenly fell silent.

Although it is not a sheath, the previous diagnosis has been overturned.

But abnormal body tissue... means that there is a tumor tissue in the patient's pulmonary valve area!

Whether benign or malignant, it is a tumor tissue!

Pulmonary valve tumors are quite rare.

"Su Yun, ask Fuguier to come up." Zheng Ren said in a deep voice.

Director Wei and Lin Ge were both stunned for a moment. What does Boss Zheng mean?

After a brief, embarrassing silence, Zheng Ren immediately realized that he was in the doctor's office in the ICU and Su Yun was not following him.

"Sorry, Director Lin and Director Wei." Zheng Ren smiled awkwardly.

"Boss Zheng? What did you find?" Director Wei asked in a low voice.

In this case of pulmonary embolism caused by thrombosis in the pulmonary artery valve, Boss Zheng also needs to use surgical procedures to treat this case?

Because some of the thrombus is not fixed in the original position, embolism in other locations is likely to occur during the surgical procedure.

So, this is a contraindication for surgical surgery!

Boss Zheng is preparing to launch an attack on the penalty area? It's impossible.

No, he wants to call Professor Rudolph Wagner. Does he want to use interventional surgery?

No, Director Mao said nothing.

"Director Wei, I also thought it was a pulmonary embolism at first." Zheng Ren said: "But after watching the movie, I felt something was wrong."

"What's the problem?" Director Wei asked.

"How to say it? In terms of subtle feeling, I initially judged that the filling defect in the pulmonary valve area is the body tissue."

"..." Director Wei was silent.

This passage is a bit awkward for ordinary people. But for doctors, the appearance of body tissue in the pulmonary valve area means that benign or malignant tumors are grown there!

I'm going to... tumors in the pulmonary valve area?

Boss Zheng really dares to think about it.

But Director Wei did not refute. He chatted with Feng Jianguo some time ago, saying that Boss Zheng may not be good at laparoscopic surgery.

Then he was slapped in the face by a standard laparoscopic emergency surgery.

Boss Zheng immediately diagnosed the pulmonary valve tumor. Director Wei really wanted to criticize Boss Zheng, but he held it back.

Forget it, listen honestly, don't make jokes like laparoscopic surgery.

"Let's go and see the patient." Zheng Ren said.

Linge felt that Boss Zheng was not under control at this time, like a small wild beast.

His mind is full of surgery and patients.

Provide more surgical opportunities for Boss Zheng? It seems that he can't do it. Besides, Director Kong has contacted Boss Zheng's community hospital.

Everyone did everything they should do, but they came a little late.

So how to do it?

Zheng Ren took out his cell phone and walked out of the doctor's office in the ICU.

"Su Yun, ICU, call Fuguier."

"You're busy, okay, the tumor of the pulmonary artery valve, I'll look for Zhao Yunlong, you can be busy."

After saying that, Zheng Ren hung up without waiting for Su Yun to say anything on the phone.

But he didn't continue to call.

"Boss Zheng, are you going to find someone with your heart?" Lin Ge immediately leaned over and asked.

"No, Su Yun will be here soon."

"Aren't Dr. Su busy?" Linge was a little confused. Did he hear it wrong?
