What surgeons also cannot do is clear the blood vessels of a large cerebral infarction.
I have mentioned before that the cerebral blood vessels are like other organs in the body, which are like a network with many large and small blood vessels. Large-area cerebral infarction means that almost all the large and small blood vessels in this network are blocked. It is impossible for surgeons to clear the vascular network of countless blood vessels.
The only thing the surgeon can do is to choose one: cut off the blocked tissue. This is what surgery is best at, cutting off the necrotic tissue is the end of it.
It is easy for doctors to cut, but it is definitely not a good thing for patients to have brain tissue cut off.
Another option is to open the cranial cavity, remove part of the skull, and release the enlarged brain tissue from the cranial cavity window opened by the doctor without compressing the other side, and then wait for the body's self-repair ability to slowly adjust back. So this kind of operation is called bone craniectomy.
After reading this, you will realize that the most advanced medicine is just this good. There are really no miracle doctors or miracle medicine in the world.
Surgery in progress.
If the opponents are willing to open up to them, the National Association trio will not be shameless and watch it in a big way.
Like Dr. Song, he unceremoniously brought a chair and sat down to watch.
...
...
Xie Wanying and classmate Pan stood together, exchanging words from time to time.
Dr. Tong's assistant had received an internal notice and was not unaware of who they were. What surprised him was what they talked about.
"Yingying, isn't this area drawn a little to the left?" Student Pan asked for instructions and had an academic exchange with Student Xie.
"If you open a window, a slight deviation in position doesn't matter. What's more important is the timing." Xie said that Pan's vision for seeing human tissue is now almost as accurate, and on the other hand, he can point out the key points.
Brain tissue is too fragile, and decompression needs to be done step by step, just like taking care of a baby. If it is reduced all at once, it may backfire and turn into malignant bulge, leading to cerebral ischemia-reperfusion injury.
When is the right time?
As mentioned in the previous chapter, brain tissue will pulsate. At this time, the surgeon will check the brain pulse. After cutting and removing the bone flap, the surgeon will touch the brain tissue with a gloved hand to feel the brain pulse and then cut the dura mater at the right time. Before the right time, the dura mater can be suspended to allow the brain tissue to further adapt to the feeling of decompression. So taking care of the brain is like taking care of a baby.
All of these were done based on the doctor's experience, without any instruments to help with reference. As the National Association trio just despised, these skills could not be replaced by imported surgical instruments.
The doctors in Dr. Tong's group who heard them were thinking: Aren't these people very young? They actually know that the most important thing about craniotomy is timing. Teachers usually don't talk about the key points of such operations, and you have to figure it out on your own, so young people can't understand it right away.
Dr. Tong, who had come into contact with the trio, remained very calm, knowing that the ultimate killer had not yet appeared.
Soon, the king bomb came.
After cutting open the dura mater, tension-relieving sutures are required to suture the artificial meninges to the dura mater to expand the area of the meninges for decompression and closure, which tests the doctor's manual skills.
"He changed his equipment." Student Pan said in the live broadcast.
"Yeah." Student Xie responded.
"He has changed tweezers three times." Student Pan suddenly became a data expert like Student Xie and started counting.
"Yeah." Xie said he understood.
The doctors in Dr. Tong's group had their eyelids twitching: Can these guys figure out Dr. Tong's tricks when they come to see their surgery for the first time?
