Chapter 2092 【2092】Four Links Developed Network
Deputy Director Lu was stunned, and suddenly felt like he was being tricked: "No, when I was talking to Dr. Song, Dr. Cao, you didn't stop—"
"I said don't worry."
Don't worry, everyone can hear the last two words.
Deputy Director Lu became even more anxious. Isn't he embarrassing? He crossed his waist and pointed in the direction of the operating room: "OK, please, don't worry. Cao Yong, don't forget, we are in the middle of an operation right now." .How can you say take it easy?"
"The problem is, you can't perform this operation even if you take the patient to the operating room on the third floor."
Who is speaking this time? Deputy Director Lu poked his head and saw Xie Wanying standing beside Cao Yong.
The gazes of other people also gathered together and fell on her personally.
As soon as Huang Zhilei heard it, he knew it was Junior Sister's voice, thinking: This must be Junior Sister's reluctance to let Senior Brother Cao talk about it.
Lin Chenrong smiled silently.
Jin Tianyu looked at the ceiling: Junior brother and junior sister...
Zhai Yunsheng glanced at his nephew's face from the corner of his eyes: Well, continue to pretend to be calm.
"Tell me, what do you mean you can't have this operation even if you go to the third floor?" Deputy Director Lu appointed her to answer the question.
Seeing Doctor Song and Brother Cao being forced, I couldn't help but speak out. Now that I have spoken, let me tell you the truth. Xie Wanying spoke politely and calmly, and said: "The first principle of dealing with an aneurysm is not whether the aneurysm can be treated, but whether the aneurysm can be treated."
This is a bit confusing. The people present in the cardiology department were a little confused again.
The aneurysm grows on the wall of the artery, so whether it is clipped or plugged off, it will affect the normal blood supply of the artery where the aneurysm is located. Doctors have to think about it before they do it.
Specifically, aneurysm embolization is divided into embolization and occlusion. The accurate medical term for embolism should be subtotal embolism preservation, that is, blood flow can continue to pass through this artery so that this artery can preserve its function.
The way to occlude aneurysms is similar to microsurgical clipping of aneurysms. The goal is that the artery cannot be preserved due to the long shape of the aneurysm. The medical term is that the parent vessel cannot be preserved, but the blood flow can only be rebuilt. The doctor had no choice but to completely block the artery, completely plugging off the aneurysm and cutting off the artery at the same time.
As for the wide neck tumor of the critical value, it is really not a big problem. Because a balloon or a stent can be used to assist the coil to prevent the coil from falling off during the operation.
Outsiders may feel terrible when they hear that all the arteries have been cut off. Without tubes to transport blood, human tissues that depend on blood nutrition will starve to death if their blood supply is cut off.
Not afraid not afraid. Cerebrovascular is a very rich and dense three-dimensional vascular network, and it is a network with well-developed transportation in all directions. It is manifested in the unique collateral circulation network we mentioned before, the circle of Willis. This ring is located at the bottom of the head. Once a blood vessel is blocked, the blood flow can be adjusted and redistributed through the ring, so as to satisfy the blood supply of all brain tissues as usual. This is also the reason why microsurgery is not afraid of clipping aneurysms to cover up aneurysms that cannot be treated with interventional surgery.
The only thing that doctors pay special attention to is that before disposing of this artery, it is necessary to determine whether the collateral circulation that can compensate for this artery is unobstructed. Don't forget that after clamping the occluded blood vessel, the collateral circulation will not work, then something serious will happen.
