Big Doctor Live Room

Chapter 967 Small Bowel Arteriovenous Malformation

"Qi Hong, what do you think?"

The eldest lady ignored Chen Qun's shocked eyes and directly asked Qi Hong, who was operating the CT at the back, with a manner that mimicked that of a certain TV boss.

The female academic bully thought for a while before giving an accurate answer.

"Probably because the tumor of the sigmoid colon is very large and there is a lot of blood flow. For ordinary contrast agents, when it reaches that part, it will be stained, and it looks like bleeding. On the contrary, for the structure of the small intestine, its bleeding is intermittent. Therefore, sometimes it cannot be clearly displayed in CT angiography and cannot be detected. However, my personal guess is less accurate than the results of computer calculations, and we will be able to make a better judgment when your demonstration images come out. "

"Don't rush, damn it, there's only one projector, so I'll show the other two on the big screen, and compare them with each other. As for the image with the highest probability, I'll show it on the projector."

Chen Qun stopped his movements quickly and put forward his opinion calmly.

"Perhaps, I will do another radiography to see where the problem is. Besides, for real-time imaging, the data will be more comprehensive and more accurate results can be obtained. I will go back to the abdominal main artery, and then go up, insert a contrast catheter into the superior mesenteric artery, and give me a contrast medium to determine the location of small intestinal bleeding."

Dongfang Wenxin did not argue with Chen Qun at this time, nor did she care about her own imaging results, but directly gave new instructions.

"I'm going to do 3D imaging of the superior mesenteric artery entrance right away."

Liang Shaoming, who had accumulated a lot of intervening knowledge, looked at the blood vessel projection on the screen and couldn't help expressing his worries.

"This entrance is too narrow. What kind of catheter do I need to use? It seems that the catheter you are using is already the thinnest. Is there a thinner one?"

Chen Qun was busy with his hands and did not forget to give an answer.

"Yes, there are three more thinner ones, but they are hardly used on weekdays. They are all in my operation box for spare. Now it seems that they are not used. I can use regular catheters to complete the work, which is mainly to save time. .OK, I have entered the superior mesenteric artery, do not change the image on your big screen, prepare to shoot. The contrast agent is 4 ml per second for 20 seconds!"

"Settings are complete, shooting has started!"

Qi Hong was on the side operating the screen, cooperating with Chen Qun's instructions with ease.

Liang Shaoming only had time to pay attention to the picture that appeared on the 3D projector at this time. He saw a bunch of colorful blood vessels of different sizes appearing in the field of vision like a bunch of messy hemp. The pipe, marking Chen Qun's real-time route, was almost completely synchronized with the hair-like black line on the big screen, without any difference in latency.

Even if Liang Shaoming has never eaten pork, he has seen pigs walk.Knowing that this is the most difficult part of all interventional procedures, you need to find a passage in a pile of spider webs, and if you make a slight mistake, all previous efforts will be wasted.This requires not only patience, but also excellent three-dimensional perception of space, which cannot be done with experience.

Moreover, the most depressing thing for everyone is that the radiography of many predetermined locations may not be able to find the real bleeding location. If you search a few times, the depression and anxiety can directly overwhelm many doctors, and they will collapse on the operating table. down.

At this moment, Chen Qun was staring at the big screen quietly. Relying on his solid clinical experience, he directed the guide wire to swim in the small intestinal artery. Towering trees of increasing complexity.Almost at the same time, the 3D projector next to it also used blue light to draw a more complex capillary network.

"We have found the bleeding point. Look at the upper left corner. The plush-like area in the picture is where the blood is seeping."

As soon as Chen Qun's voice fell, the black line of the capillary that went straight through it immediately turned light red, and the surrounding connected blood vessels also turned green, which was particularly striking on the black and white CT image. clear.Immediately afterwards, on the 3D projector next to it, there was also a schematic diagram of rose-red blood vessels with the same nine bends and eighteen turns, and then green branches grew around it.

Liang Shaoming opened his mouth wide open. He knew that only black and white colors would appear on any hospital CT projector. The step of coloring hides a huge computing power behind it, which can be said to be an out-and-out black technology.

The machines and equipment of their Xiangyun Hospital are the most advanced in the country, and they are considered first-class in the world. There are at most a little technical deviation, but even with such a machine, it takes half an hour to complete a 3D image. to be calculated.

As for the young lady, real-time imaging can be achieved, and neither the computing power nor the most important programming behind it can be bought with money.

In the future, the frontier of medicine will be in this direction. It is not wrong for him to keep up with Chen Qun's direction. After ten years of hard work, plus Chen Qun who can ask for advice and study, it is not just a matter of selecting an academician. Even more, he can become the leader of the respiratory department in the world, and he will create a technological revolution, so that all doctors in the respiratory department cannot bypass his existence.

This is the greatest ambition buried in his heart!
"Chen Qun, keep going straight ahead, turn left at the bifurcation point in front, and after passing through the circular blood vessel in front, you can see the bleeding point. Slow down, don't run to the side road, there are three positions here Same fork!"

With a wave of her hand, the eldest lady directly magnified the image on the projector twice, and indicated the direction of travel with her middle finger.Chen Qun naturally followed the eldest lady's instructions and walked forward.

For Chen Qun, he did not perform any practice in the system space at all during this operation. For him, practice is no longer necessary. He almost has an unconditioned reflex to the structure of the human body, and many operations have become habitual responses. Before he could understand it himself, he had already completed the walk and time travel.

"Slower, after passing this bifurcation point, the contrast catheter will reach the bleeding point."

"Have arrived at the location, start shooting!"

As the structure on the image became clearer and clearer, Chen Qun's hand stopped for a moment, and a messy tissue structure appeared in front of the rose-red blood vessels.

Qi Hong, who was in charge of the recording, let out an exclamation, "Is this a small intestinal arteriovenous malformation?"

"Yes, it should be congenital, it existed before birth, and the proportion increases with the growth of the body. It is this vascular malformation that bleeds at this time, causing bleeding in the small intestine. I need to use an intravascular coil Embolism to stop the bleeding, Xiaoxin, let the computer estimate the distance of the bleeding point."

Dongfang Wenxin gave Chen Qun a white look, knowing that this guy deliberately asked her to behave, otherwise, with Chen Qun's "rich clinical experience", he wouldn't ask a nurse for any opinions.

The eldest lady gestured twice on the stereoscopic projection with her finger, and finally gave the answer judged by the computer.

"Prepare a coil with a diameter of 1.5 millimeters and a length of three centimeters!"

The eldest lady gave the answer while performing her duties as an equipment nurse, and then felt that it was a big loss.

"Here, Mr. Chen Qun, the spiral plate is placed in front of you, and you don't even reach out to take it yourself. If you insist on squeezing a little nurse, do you have to wait for me to feed you when you eat?"

Chen Qun answered calmly with a serious look.

"Nurse, please abide by the rules of the operating room, and don't violate the procedures! Well, I'll be honest, I'm afraid that I will do it myself, and you say that I deprived you of the fun and responsibilities of the equipment nurse, I am also very difficult!"
