Chapter 470: : Thank you for your help

Latest website: Meng Xi took the scalpel, it seems like a baton!
What follows is just two different operations!
And the difficulty increases proportionally.
Meng Xi glanced at Chen Cang: "Build a temporary blood vessel bridge."
Chen Cang nodded quickly.
During aortic constriction surgery, it is necessary to block the descending aorta above and below the constricted section. This is to protect the spinal cord and distal organs from the damage caused by ischemia during the descending aorta block.
Generally, you can choose low temperature, but you can also choose to build temporary vascular bridge and establish left heart flow.
Although Meng Xi's choice to build a temporary vascular bridge will increase the difficulty of surgery, the safety factor of this method is more reliable than low temperature!
Because no one is sure how long the next surgery will last.
Hypothermia is limited, and prolonged time can cause ischemic damage.
After vascular scar changes, does it have endometrial necrosis?
Therefore, there is still much to consider.
Just as everything was stable, Meng Xi began to open the wall of the aorta, which was already scarred, like a tumor.
Chen Cang's face suddenly changed, he felt that this should be more than just a vascular scar!
Maybe there is something else.
At this time, non-invasive vascular forceps are clamped at the upper and lower ends of the aorta.
Meng Xi looked up and asked well: "Have you done any angiography?"
Suddenly, he shook his head suddenly: "No."
Hearing here, Meng Xi suddenly hesitated.
When thinking of this, Chen Cang couldn't help reminding him: "Mr. Meng, be careful behind, it may be an aneurysm!"
Meng Xi nodded, she had expected it.
If it is pure scar tissue, it is not so serious.
Meng Xi was holding a scalpel and did not cut the vessel wall directly, but opened it for exploration.
After the blood vessels opened, Chen Cang saw the existence of hemangioma. Although it was small, it was real!
[Aortic Hemangioma: Cystic! lv57. 】
Ok!
That should be good news.
Not a malignant tumor.
However, Chen Cang looked at the tumor tissue at the base of the aneurysm.
This means that if the tumor tissue is completely removed, the end-to-end anastomosis distance is not enough!
Originally, the narrowed section was removed, and end-to-end anastomosis can also be used to suture the vessel wall. However, the presence of this uninvited guest "aneurysm" makes the difficulty of the entire operation proportionally increased.
Because it is likely that after the tumor has been completely removed, the descending aorta does not extend enough, and end-to-end suture of the blood vessel seems impossible.
What can I do?
Blood vessel transplant?
Patch?
Or what?
All of a sudden many questions are now before everyone.
Meng Xi took a deep breath and frowned!
Do a bypass transplant?
Bypass transplantation will definitely cause irreversible damage to the patient's upper limbs. In fact, the blood vessels sent to the upper arm are borrowed for use in the aorta. This will work well for the aorta, but may damage the upper arm!
Just when everyone didn't know how to reach a conclusion in the end.
Chen Cang hesitated and said, "I have a suggestion."
Meng Xi looked up at Chen Cang, his eyes brightened: "What advice?"
Chen Cang said, "Fill Jiang with another wound!"
Chen Cang's idea directly made Meng Xi grabbed a bit of thought, but he couldn't catch the specific details: "Speak more."
Chen Cang thought for a while, but now it is not detailed!
Moreover, it is better to do it in detail!
Thinking of this, Chen Cang said directly to Meng Xi, "Ms. Meng, give me the knife!"
Meng Xi hesitated for a moment, and then he gave Chen Cang a scalpel.
And Ran could not help but swallowed saliva.
Chen Cang ... what kind of specialty is it?
He had a terrific surgery on his chest, so he knew it well.
But ... Is he also so strong in extracardiac surgery?
At this time, Chen Cang glanced at Meng Xi, sighed, and it was about 30 o'clock again.
The previous operation just gained 5 points of favorability, which allowed Chen Cang and Meng Xi to reach 60 points of favorability.
In this way, you can redeem for tertiary surgery.
Chen Cang did not hesitate to choose to exchange for [aortic constriction surgery]!
After the exchange, Chen Cang started training without hesitation.
This operation is no longer a simple [aortic constriction surgery], but also [aortic aneurysm], and Chen Cang still needs 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 eye. 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 + all the base of the aortic aneurysm + make a knife across the aortic wall.
Because of two simple resections, an end-to-end anastomosis cannot be performed on the entire vessel.
But if you add another knife, it just makes the end end at a better angle!
What does that mean?
It is not necessary to cut off all the ends, but only to remove the tumor tissue and scar tissue, and then it must not be sutured at this time, but Chen Cang can cut off the inappropriate place with a scalpel. In this case, Sutures are possible.
Thinking of this, Chen Cang said to do it without hesitation.
Picking up the scalpel, the precise tumor tissue on the blood vessel wall is removed.
However, during the resection, Chen Cang deliberately cut a few places. After that, the scar tissue was processed. This required the removal of a group of blood vessel walls!
...
Surgery step by step!
When Chen Cang cut all the tissues, the ports on both sides became irregular ports.
Meng Xi looked at this scene aggressively!
Even Jing Ran and her colleagues, assistants, and anesthesiologists were crying and laughing.
Is this dog shit?
How is this stitched!
Everyone looked at Chen Cang's rugged two ports with a grimace.
It might as well be cut all!
At this time, Chen Cang made a gentle stroke on the upper end of the aorta, and then brought the two ends together ...
Suddenly!
The whole style changed suddenly!
Everyone took a breath.
Can he do that?
Meng Xi was looking at Chen Cang inconceivably ~ EbookFREE.me ~ with shock in his eyes.
Chen Cang is a doctor of surgical surgery, this is clearly a magician!
The two ends of the dog just now can be tightly combined!
Isn't he a magician?
How can a surgeon play like this?
Clever use of this irregular port, Chen Cang cleverly protects the blood vessels next door from being killed!
The blood vessel next door no longer needs to be transplanted, and I can't help feeling relieved: I was scared to death, and I was almost cut ... Thank you, brother.
...
...
ps: hey, thanks for the rewards of the hellcat boss, became the head, thank you!
