Meng Xi took the scalpel, as if it was a baton!

Next are two completely different surgeries from what just now!

And the difficulty also increases proportionally.

Meng Xi glanced at Chen Cang: "Build a temporary vascular bridge."

Chen Cang nodded quickly.

During aortic constriction surgery, it is necessary to block the upper and lower descending descending descending aorta, which is to protect the spinal cord and distal organs during the descending aorta from damage caused by ischemia.

Generally, low temperatures can be selected, but you can also choose to build temporary vascular bridges and establish left heart flow.

Although Meng Xi’s choice to build a temporary vascular bridge will increase the difficulty of the surgery, the safety factor of this method is more reliable than that of low temperatures!

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

The low temperature time is limited, and too long time can cause ischemia injury.

After the vascular scar changes, will there be necrosis of the endometrium?

Therefore, there are many things to take into account.

Just as everything was going on, Meng Xi began to open the wall of the aortic blood vessel that had accumulated scars like a tumor.

Chen Cang's face suddenly changed. He felt that this should be more than just a simple vascular scar!

Maybe there is something else.

At this time, the non-invasive blood vessel clamps are clamped at the upper and lower ends of the aorta.

Meng Xi looked up and asked Jing Ran: "Have you done an angiography?"

Jing Ran was stunned and shook his head: "No."

When Meng Xi heard this, she suddenly became hesitant.

When Chen Cang thought of this, he couldn't help but reminded: "Teacher Meng, be careful that there may be an aneurysm behind him!"

Meng Xi nodded, she had already expected it.

If it is simply scar tissue, it will not be so serious.

Meng Xi held a scalpel in his hand and did not directly cut off the blood vessel wall, but instead incited and investigated.

When the blood vessels opened, Chen Cang immediately saw the existence of hemangioma. Although it was not big, it was real!

【Artificial hemangioma: cystic!lv57.】

All right!

This should be good news.

Not a malignant tumor.

However, Chen Cang looked at the tumor tissue at the base of the aneurysm and had already extended a little...

This means that if all the tumor tissue is removed, the distance between the end and end is not enough!

Originally, the narrowing segment could be removed, and end-end anastomosis could be used to suture the blood vessel walls, but the existence of this uninvited "aneurysm" has increased the difficulty of the entire operation in proportion.

Because it is very likely that after the tumor tissue is completely removed, the extension distance of the descending aorta is not enough, and the end suture of the blood vessels seems to be impossible.

What should I do?

Vascular transplant?

Patch?

Or what to do?

Now many questions are placed in front of everyone.

Meng Xi took a deep breath and frowned!

Do bypass transplant?

If a bypass transplantation is sure to cause irreversible damage to the patient's upper limbs. In fact, the blood vessel sent to the upper arm is borrowed for use for the aorta. This will be effective for the aorta, but may damage the upper arm!

Just when everyone didn't know how to draw a conclusion in the end.

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

Meng Xi looked up at Chen Cang, his eyes lit up: "What suggestions?"

Chen Cang said: "Please fill another wound for the invasion!"

Chen Cang's idea directly made Meng Xi seem to have caught a glimmer of thought, but he couldn't catch it in detail: "Tell me more details."

Chen Cang thought about it again and said, now he will not say in detail!

Moreover, it is better to do more details than to say it!

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

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

And Jing Ran couldn't help swallowing.

What is this Chen Cang... professional?

He had a great external thoracic surgery, Jing Ran knew.

But... is his external surgery so powerful?

At this time, Chen Cang glanced at Meng Xi and sighed. Another 30 points of favorability was about to disappear.

The last surgery just gained 5 points of favorability, which made Chen Cang and Meng Xi’s favorability exceed 60 points.

In this way, you can redeem the third-level surgery.

Chen Cang did not hesitate and directly chose to exchange for [Aortic Constriction Surgery]!

After redeeming, Chen Cang did not hesitate and started training directly.

This operation is no longer a simple [aortic constriction surgery], but also a [aortic aneurysm]. Chen Cang now wants to add a little to him, that is [aortic injury].

What Chen Cang had to do was to accurately remove the base of the aortic aneurysm in the eyes. Even if it was removed accurately, if sutured, it would still cause aorta stenosis.

What Chen Cang needs to do is to remove the scar + remove the basal part of the aortic aneurysm + cut the aortic wall.

Because of the two resections alone, the entire blood vessel cannot be end-endly anastomotic.

But if you add another knife, it will just put Duan in a better combination angle!

What does it mean?

It means that there is no need to cut off both ends, but only the tumor tissue and scar tissue need to be removed, and then it will definitely not be sutured at this time. However, Chen Cang can cut off the inappropriate areas with a scalpel. In this way, suturing may be possible.

Thinking of this, Chen Cang did it as soon as he said it, without hesitation.

Pick up the scalpel and start to remove the tumor tissue on the blood vessel wall accurately.

However, during the removal, Chen Cang deliberately cut more places, and then he treated the scar tissue, which required cutting off all the blood vessel walls!

...

The surgery is carried out step by step!

After Chen Cang removed all the tissue, the ports on both sides became irregular ports.

Meng Xi looked at this scene with a confused look on her face!

Even Jing Ran and his colleagues, assistants, and anesthesiologists were both amused and crying.

Is this a dog chewed?

How to stitch this!

Everyone looked at Chen Cang's two rugged and weird ports, looking confused.

It's better to cut them all!

At this time, Chen Cang gently drew a path at the upper end of the aorta, and then turned the two ends together...

Suddenly!

The whole style changed suddenly!

Everyone gasped.

Is this okay?

Meng Xi looked at Chen Cang incredibly, his eyes full of shock.

Chen Cang is a surgical surgeon, he is clearly a magician!

The two ends that were biting just now could be closely combined!

Isn't he a magician?

How can a surgeon play like this?

Cleverly using this irregular port, Chen Cang cleverly avoided the blood vessels next door from the death disaster!

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