Chapter 2092: 【2092】The four-way developed network
"I said don\'t worry."
Don\'t worry, everyone can hear the last two words.
Deputy Director Lu became even more anxious. Wasn\'t he embarrassed, he put on his hips and pointed in the direction of the operating room: "Xingxingxing, you said, don\'t worry. Cao Yong, don\'t forget, it is now during the operation. How can you say don\'t worry?"
"The problem is, now you can\'t do this surgery even if you take the patient to the operating room on the third floor."
Who is speaking this time? Deputy Director Lu looked around and saw Xie Wanying standing beside Cao Yong.
The eyes of the others came together to fall on her.
Huang Zhilei knew that it was the voice of the junior sister, and thought: This must be because the junior sister was reluctant to talk to senior brother Cao.
Lin Chenrong smiled silently.
Jin Tianyu looked at the ceiling: Junior, junior and senior sisters...
Zhai Yunsheng glanced at his nephew\'s face from the corner of his eyes: Well, he continued to pretend to be calm.
"Tell me, what is it that you can\'t do this surgery even if you go to the third floor?" Deputy Director Lu assigned her to answer the question.
Watching Doctor Song and Senior Brother Cao being forced, couldn\'t help but speak out. Now that he has spoken, let him speak frankly. Xie Wanying said in a gentle and calm tone, "The first principle of dealing with aneurysms is not whether the aneurysm can be dealt with, but whether the aneurysm can be dealt with."
This is a bit of a twist. The gang from the Cardiology Department present was a little stunned again.
Aneurysm grows on the arterial wall, so whether it is clipped or plugged, it will affect the normal blood supply of the artery where the aneurysm is located. Doctors have to figure this out before they do anything.
Specifically, aneurysm embolization is divided into embolization and occlusion. The accurate medical term for embolization should be subtotal embolization preservation, that is, blood flow can continue to pass through the artery so that the artery can preserve its function.
The method of occluding the aneurysm is similar to the method of clipping the aneurysm with microsurgery. The goal is that due to the long shape of the aneurysm, the artery cannot be preserved. The medical term is called the parent vessel, which cannot be preserved, and only the blood flow can be reconstructed. The doctor had no choice but to completely block the artery, completely plugging the aneurysm and cutting off the artery.
As for the wide neck tumor of the critical value, it is really not a big problem. Because the balloon or stent can be used to assist the coil to prevent the coil from falling off during the operation.
It may be scary for outsiders to hear that all arteries are cut off. There is no tube to transport blood, and the human tissue that needs to rely on blood for nutrition will be starved to death if the blood supply is cut off.
not afraid not afraid. The cerebral blood vessels are a very rich and dense three-dimensional blood vessel network, which is a network with well-developed traffic. It is manifested in the unique collateral circulation network we mentioned earlier, the circle of Willis. This ring is located at the bottom of the head. Once the blood vessels are blocked, the blood flow can be redistributed through the adjustment of the ring, so as to meet the blood supply to all brain tissues as normal as possible. This is why microsurgery can clip aneurysms without fear of clipping aneurysms that cannot be treated with interventional surgery.
The only thing that the doctor pays special attention to is that it is necessary to determine whether the collateral circulation that can compensate for this artery is unobstructed before doing the treatment of this artery. Don\'t clip the occluded blood vessel, and the collateral circulation will not work, it will be a big problem.
