Meng Xi took the scalpel and seemed to be a baton!


    Next and just now are two very different operations!


    And the difficulty increases proportionally.


    Meng Xi took a look at Chen Cang: "build a temporary blood vessel bridge."


    Chen Cang nodded quickly.


    During aortic coarctation surgery, it is necessary to block the descending aorta up and down the narrowed segment, which is to protect the spinal cord and distal organs from ischemia during the blocking of the descending aorta.


    Generally, hypothermia can be selected, but temporary vascular bridge and left ventricular circulation can also be selected.


    Meng Xi chose to build a temporary vascular bridge. Although it will increase the difficulty of operation, the safety factor of this method is more reliable than low temperature!


    Because no one is sure how long the next operation will last.


    The time of hypothermia is limited, and too long will cause ischemic injury.


    Is there necrosis of intima after the change of vascular scar?


    Therefore, there are many things to take into account.


    While everything was going on steadily, Meng Xi began to lift the aortic vascular wall that had been formed by scar accumulation like a tumor.


    Chen Cang suddenly changed his face. He felt that this should not be just a simple vascular scar!


    Maybe there''s something else.


    At this time, noninvasive vascular forceps were clamped at the upper and lower ends of the aorta.


    Meng Xi raised his head and asked Jingran, "have you done angiography?"


    Jing ran was stunned and immediately shook his head: "No."


    Hearing this, Meng Xi immediately hesitated.


    Chen Cang thought of this and couldn''t help reminding: "Mr. Meng, be careful in the rear. It may be an aneurysm!"


    Meng Xi nodded. She had expected it.


    If it was simply scar tissue, it would not be so serious.


    Meng Xi, holding a scalpel, did not directly cut the blood vessel wall, but cut it open for exploration.


    When the blood vessels opened, Chen Cang immediately saw the existence of hemangioma. Although it was small, it was real!


    [aneurysm: cystic! Lv57.]


    ok


    This should be good news.


    It''s not a malignant tumor.


    However, looking at the tumor tissue at the base of the aneurysm, Chen Cang has some extension


    This means that if all the tumor tissues are removed, the distance of end-to-end anastomosis is not enough!


    Originally, end-to-end anastomosis could be used to suture the vascular wall after resection of the narrowed segment, but the existence of this uninvited "aneurysm" increases the difficulty of the whole operation in proportion.


    Because it is likely that after all tumor tissues are removed, the extension distance of the descending aorta is not enough, and the end-to-end suture of blood vessels seems impossible.


    What about this?


    Vascular transplantation?


    Patch?


    Or what?


    Now many problems are put in front of everyone at once.


    Meng Xi took a deep breath and frowned!


    Bypass?


    Bypass grafting will definitely cause irreversible damage to the patient''s upper limb. In fact, it is to borrow the blood vessels sent to the upper arm to be used for the aorta. In this way, it has a good effect on the aorta, but it may damage the upper arm!


    Just when people don''t know how to draw a conclusion.


    Chen Cang hesitated and said, "I have a suggestion."


    Meng Xi looked up at Chen Cang and said, "what advice?"


    Chen Cang said, "take the initiative to fill another wound!"


    Chen Cang''s idea directly made Meng Xi seem to grasp a trace of idea, but he couldn''t grasp it: "say it in detail."


    Chen Cang thought about it. I can''t say it in detail now!


    Moreover, it is better to say in detail than to do in detail!


    Thinking of this, Chen Cang directly said to Meng Xi, "teacher Meng, give me the knife!"


    Meng Xi was stunned. He was a little stunned and handed the scalpel to Chen Cang.


    And Jing ran couldn''t help swallowing his saliva.


    What is Chen Cang''s major?


    He had a great extrathoracic operation and knew it well.


    But... Is he so strong in extracardiac surgery?


    At this time, Chen Cang glanced at Meng Xi and sighed. It was 30 o''clock again, and his popularity was going to be gone.


    The last operation just gained 5 points of favor, which made Chen Cang and Meng Xi''s favor break through 60 points.


    In this way, you can exchange for level III surgery.


    Without hesitation, Chen Cang directly chose to exchange for [aortic coarctation surgery]!


    After the exchange, Chen Cang did not hesitate to start training directly.


    This operation is no longer a simple "aortic coarctation operation", but also complicated with "aortic aneurysm", and Chen Cang now has to add a little to him, that is, "aortic injury".


    What Chen Cang has to do is to accurately remove the base of the aortic aneurysm according to the eyes. Even if it is very accurate, if it is sutured, it will still cause aortic stenosis.


    What Chen Cang has to do is to remove the scar + remove all the base of the aortic aneurysm + draw a knife on the aortic wall.


    Because of simple two resection, it is impossible to anastomose the whole blood vessel end to end.


    But if you add another knife, it just makes the end in a better combination angle!


    What do you mean?


    It is not necessary to cut off all the two ends, but only those tumor tissues and scar tissues. Then it is certainly impossible to suture at this time, but Chen Cang can cut off the inappropriate places with a scalpel. In this way, suture is possible.


    Thinking of this, Chen Cang said to do it without hesitation.


    Pick up the scalpel and begin to accurately remove the tumor tissue on the vascular wall.


    But when cutting, Chen Cang intentionally cut more places. Then, he dealt with scar tissue, which requires cutting off all a group of blood vessel walls!


    ……


    The operation is carried out step by step!


    When Chen Cang removed all the tissues, the ports on both sides became irregular ports.


    Meng Xi looked at this scene with an ignorant face!


    Even Jing ran and his colleagues, assistants, and anesthesiologists can''t cry or laugh.


    Is this a dog bite?


    How does this sew!


    Everyone looked at Chen Cang''s rugged and strange two ports and looked confused.


    It''s better to cut it all!


    At this time, Chen Cang gently scratched at the upper end of the aorta, and then put the two ends together


    Suddenly!


    The whole painting style suddenly changed!


    Everyone took a breath.


    Is that all right with him?


    Meng Xi looked at Chen Cang strangely, and his eyes were full of shock.


    Chen Cang is a surgical surgeon. It''s clearly a magician!


    Just now, the two ends of the dog can be closely combined!


    He''s not a magician what?


    How can surgeons play like this?


    Skillfully using this irregular port, Chen Cang skillfully saved the blood vessels next door from death!


    The blood vessel next door doesn''t need to be transplanted, and I can''t help but breathe a sigh of relief: I was scared to death and almost cut... Thank you for not killing me.
