    Deputy Director Lu was stunned, and suddenly felt like he had been tricked into something: "No, when I was talking to Dr. Song, Dr. Cao, you didn't stop me -"

    "I told you not to worry."

    ¡°Don¡¯t worry, everyone can hear the last two words.

    Deputy Director Lu became even more anxious. Wouldn't it be embarrassing for him? He put his hands on his hips and pointed in the direction of the operating room: "Okay, okay, okay, don't worry. Cao Yong, don't forget, we are in surgery now."  .How can you say don't worry?"

    "The problem is, now you can't do this operation 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 next to Cao Yong.

    The eyes of other people also focused on her.

    Huang Zhilei knew it was junior sister's voice as soon as he heard it, and thought: This must be junior junior sister who couldn't bear to be talked to by senior brother Cao.

    Lin Chenrong laughed silently.

    Jin Tianyu looked at the ceiling: Junior brother and junior sister, these two

    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 do this surgery even if you go to the third floor?" Deputy Director Lu was good at appointing her to answer the question.

    ¡°Seeing Doctor Song and Senior Brother Cao being forced, I really couldn¡¯t help but speak out.  Now that you've opened your mouth, let's just say it frankly.  Xie Wanying's tone was gentle and calm, and she said: "The first principle in dealing with aneurysms is not whether the aneurysm can be treated, but whether the aneurysm can be treated."

    This is a bit convoluted.  The people in the cardiology department present were a little confused again.

    Aneurysm grows on the artery wall, so whether it is clipped or plugged out, it will affect the normal blood supply of the artery where the aneurysm is located.  Doctors must plan for this before taking action.

    ??Specifically, aneurysm embolization is divided into embolization and occlusion.  The accurate medical term for embolization is subtotal embolization preservation, which means that blood flow can continue to pass through the artery so that the artery can preserve its function.

    The method of occluding an aneurysm is similar to the method of microsurgical clipping of an aneurysm.  The goal is that due to the shape of the aneurysm, the artery cannot be preserved. In medical terms, the parent vessel cannot be preserved, and the only way is to reestablish blood flow.  The doctor had no choice but to completely block the artery, plugging the aneurysm completely and severing the artery at the same time.

    As for the critical wide-neck tumor, it¡¯s really not a big problem.  Because a balloon or stent can be used during surgery to assist the coil to prevent the coil from falling off.

    ??????????????????????????????????????????????????????????????????????????????????????Outsiders may feel scary when they hear that all arteries have been severed.  Without tubes to transport blood, human tissues that rely on blood for nutrition will normally starve to death if their blood supply is cut off.

    Don¡¯t be afraid. Don¡¯t be afraid.  The cerebral blood vessels are a very rich and dense three-dimensional blood vessel network, and it is a network with well-developed transportation links.  It is manifested in the unique collateral circulation network we mentioned before, the loop of Willis.  This ring is located at the bottom of the head. Once any blood vessel is blocked, the blood flow can be redistributed through the ring adjustment to meet the normal blood supply to all brain tissues as much as possible.  This is why microsurgery can be used to clip aneurysms without fear of aneurysms that cannot be treated with interventional surgery.

    The only thing that doctors pay special attention to is that before dealing with this artery, they need 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, and something serious will happen.  (Remember the website address: www.hlnovel.com
