What surgeons also cannot do is unblock the blood vessels of a large cerebral infarction.
As mentioned before, the cerebral blood vessels are like a network like other organs in the body, with many large and small blood vessels densely packed together. A large-scale cerebral infarction means that almost all the large and small blood vessels in this network are blocked. It is impossible for a surgeon to completely unblock a network of countless blood vessels.
The only thing the surgeon can do is choose one and cut out the blocked tissue. This is what surgery is best at, cutting out the necrotic tissue and everything is over.
It is easy for doctors to cut off brain tissue, but it is definitely not a good thing for patients to cut off brain tissue.
Another option is to open the cranial cavity and remove part of the skull, allowing the enlarged brain tissue to be released from the cranial cavity window opened by the doctor without compressing the other side, and then wait for the body's self-healing ability to slowly adjust back. So this kind of surgery is called craniectomy.
When you see this, you will find that the most advanced medicine is nothing more than this. There are really no miracle doctors or miracle medicine in the world.
The operation is in progress.
The opponents are willing to open up to them, and the National Association trio will not be shameless and watch with great fanfare.
Dr. Song, for example, did not hesitate to bring a chair to sit and watch.
Xie Wanying and classmate Pan stood together and exchanged words from time to time.
Dr. Tong's assistant had received an internal notification. It was not that he didn't know who they were. What was surprising was their discussion.
"Yingying, did they draw this area a little to the left?" Classmate Pan asked for instructions and had an academic exchange with classmate Xie.
"If you open the window, it will matter if the position is a little off. What's more important is the timing." Xie said that now Pan's vision of human tissue is less different and more accurate. On the other hand, he pointed out the key point.
The brain tissue is so strong that decompressing it requires quick and step-by-step steps, just like taking care of a big baby. If the reduction is done in one step, it may be counterproductive and cause malignant bulge, which may lead to cerebral ischemia-reperfusion injury.
When is the right time?
As discussed in later chapters, brain tissue pulsates. At this time, the surgeon has to diagnose the brain pulse. Before cutting and removing the bone flap, the doctor touches the brain tissue with gloved hands to feel the brain pulse, and then chooses an opportunity to cut the dura mater. Before waiting for the right time, the dura mater cannot be hung up, allowing the brain tissue to take a step back to adapt to the feeling of decompression. Therefore, taking care of the cerebellum is like taking care of a big baby.
Those are all based on the doctor's experience. Is there any instrument that can help with reference? As the National Association of Eight members just despised, those skills cannot be replaced by surgical instruments.
The doctors on Dr. Tong's team who heard us were thinking: Are those people very young? I actually understand that the most important thing about craniectomy is timing. The key points of such a surgery are clearly explained by the teacher, and they are all understood by oneself, so the young people can understand it immediately.
Dr. Tong, who had been in contact with the eight-person group, was very calm and knew that Wang Zha had not yet appeared.
Very slowly, Wang Zha arrived.
Before cutting the dura mater, tension reduction sutures are required, and the artificial meninges are sutured under the dura mater to enlarge the meningeal area and close it under decompression, which tests the doctor's manual skills.
"I changed the equipment." Pan said live.
"Yeah." Student Xie responded.
"I have changed my optical tweezers eight times." Student Pan suddenly turned into a data geek like Tong Xie.
"Yeah." Xie said clearly.
The doctors on Dr. Tong's team had their eyelids twitching: Can those guys see something fishy about Dr. Tong when they come to our surgery for the first time?
Thank you for your support! ! ! Good night, dears~
