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 large and small blood vessels densely packed together. Large-area cerebral infarction means that almost all the large and small blood vessels in this network are blocked. Let the surgeon create a vascular network similar to countless blood vessels.
Total dredging is impossible.
The only thing the surgeon can do is choose one and cut out the blocked tissue. This is the best job of surgery. Cut out the necrotic tissue and everything will be 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. That's why this kind of surgery is called
Decompressive 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 it up for them to see, and the National Association trio will not be shameless and watch it 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 the 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, a little deviation in the position will matter. What's more important is the timing." Classmate Xie said that Classmate Pan's vision of human tissue is less different now and more accurate. On the other hand, he pointed out the key point.
The brain tissue is too strong, so decompressing it needs to be done quickly and step by step, just like taking care of a big baby. If the pressure is reduced 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 mentioned in later chapters, the brain tissue will pulsate. At this time, the surgeon will diagnose the brain pulsation and feel the brain pulsation before cutting and removing the bone flap.
, and then choose 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, so taking care of the cerebellum is like taking care of a big baby.
For those, it all depends on the doctor's experience. Is there any instrument that can help and refer to it? As the eight-person group of the National Association 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? They actually understand that the most important thing in cranial decompression is timing. The key points of such surgery are all explained by the teacher.
I understand it on my own, so even the young can understand it right away.
Dr. Tong, who had been in contact with the people in 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 statistician 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?
