This problem is actually the most important reason that limits whether an adult heart is suitable for placement in a young child, which is completely different from liver transplantation. The upper limit of the technology that Xie mentioned is once again reflected here.
For example, when the donor heart is placed in the recipient, the larger donor blood vessel is thicker than the recipient blood vessel. Especially when the large-caliber donor heart artery is connected to the small-caliber recipient artery, you should not imagine a large-caliber rubber tube being pulled together and barely sutured to a small-caliber rubber tube.
What you should think of is that because a pump that is many times more powerful than the original pump is connected to the front of the large-diameter rubber hose, the small water pipe is forced to be connected to a high-pressure water gun. Do you think that these small blood vessels will be afraid of being burst by the large flow of blood at any minute?
Where will the most vulnerable point appear? Undoubtedly, it is the anastomosis where the doctor uses needle and thread to connect and suture the two large and small blood vessels during the operation. Now you can understand why I was afraid of anastomotic leakage after surgery.
To prevent the fragile sutures from bursting, reducing the anastomosis is one method, which has been mentioned before. Now, if the volume of the donor heart is sufficient, the doctor can use the double-cavity cava method. Of course, the double-cavity cava method is better than the whole heart method.
But the surgeon just said: Be prepared to perform the anastomosis with all your heart.
First assistant doctor Cheng Yuchen was confused first: Why?
When the assistant doctor asked, the third assistant student Wei and other medical students watching in the operating room were even more confused. They had no experience and had no idea what problems the current operation was facing.
Don't easily say that Dr. Cheng and Wei are stupid. Duan Sanbao and Pan Shihua, who had returned, stood on the sidelines, looking at the surgical field for a long time, also wondering what the surgeon meant by his words.
...
...
Unable to think of a reason, students Pan and Wei habitually looked to student Xie for the answer.
In order to live up to their expectations, Xie said the most stubborn thing in history: "Because if we do this, the surgery will be more beautiful and perfect."
What! If Dr. Cheng Yuchen wasn't wearing a mask, her wide-open mouth would have shown that she was going to be slapped.
Isn't this nonsense? Taking a big risk just to make the surgery more beautiful and perfect?
Classmate Xie, you will be scolded for talking nonsense like that.
After waiting for a few seconds, no one saw the surgeon's anger. Dr. Cheng Yuchen was so frightened that he closed his mouth.
The group of people were so shocked that they couldn't be more shocked. The surgeon just kept silent, which was enough to prove that Xie was right.
What? Do you think that the big guys are taking risks by pursuing perfect and beautiful surgery without regard for the safety of the patients? They are big guys. They have the technical confidence.
Why must the donor heart be connected to the imperfect recipient heart when the donor heart is so beautiful and complete? The recipient itself suffers from cardiomyopathy, so why keep the diseased myocardium? Wait for the remnants of the disease to remain in the patient's body and find an opportunity to do evil? A surgeon holding a scalpel in the operating room cuts off the disease, and if there is a chance, he must cut it off as thoroughly as possible.
All the classic surgical operations in history show the surgeons’ constant pursuit of perfection. It can be said that the bigger they are, the more likely they are to have this “disadvantage” of excellence.
Cao Zhao didn't care about other people's surprise. The two small whirlpools in his eyes under the surgical magnifying glass on his head were thinking: Am I being hidden something by this group of guys again?
(National Association: Yes, touching the teacher’s head is Xie’s strong point.)
