This issue is actually the most important reason that limits the suitability of adult hearts for transplantation into young children. It is completely different from liver transplantation. The upper limit of suitable technology mentioned by Xie is once again reflected here.
For example, after the donor heart is placed in the recipient, the large donor blood vessel is thicker than the recipient blood vessel. Especially when a large-diameter donor heart artery is connected to a small-diameter recipient artery, what you have to think of is not a large diameter.
It is as simple as pulling the large-diameter rubber tube together and barely sewing it into a small-diameter rubber tube.
What you should think of is that because a pump many times stronger than the original pump is connected to the front of the large-diameter rubber pipe, it becomes a small water pipe and is forced to be connected to a high-pressure water gun. Do you think this small blood vessel will be damaged every minute?
Afraid of being overwhelmed by the large flow of blood.
Where will the most vulnerable bursting point appear? It is undoubtedly the anastomosis where the doctor uses needles and threads to connect and sew the two large and small blood vessels during the operation. Now you can understand why we were afraid of postoperative anastomotic leakage.
In order to prevent the fragile sutures from exploding, reducing the anastomosis is one method. This has been mentioned before. Now that the volume of the donor heart is sufficient, doctors can use the double-caval cava method. Of course, the double-caval method is better than the whole-heart transplant method.
It’s law.
However, the surgeon said: Be prepared to agree wholeheartedly.
Doctor Cheng Yuchen from Yishu was the first to be confused: Why?
When they heard Yishu's expression, the third assistant's classmate Wei and the other medical students watching in the operating room were even more confused. They were inexperienced and had no idea what the problem was during the current operation.
Don't easily say that Dr. Cheng and Classmate Wei are not smart because of this. Duan Sanbao and Pan Shihua, who came back, stood by the side looking at the surgical field for a long time, thinking about what the surgeon meant.
Really unable to think of a reason, Classmates Pan and Wei habitually looked to Classmate Xie for answers.
Living up to their expectations, Xie said the most stubborn words in history: "Because if you do this, the surgery will be more beautiful and perfect."
What! If Dr. Cheng Yuchen hadn't been wearing a mask, her open mouth would have made her stand.
Isn’t this playing the piano randomly? Taking big risks just to make the surgery more beautiful and perfect?
Thanks, classmate, you will be punished for talking nonsense like this.
After waiting for a few seconds, no one saw the surgeon's anger. Dr. Cheng Yuchen was so frightened that he closed his mouth.
A group of people were extremely shocked. As long as the surgeon didn't say anything, it was enough to prove that Xie was right.
What? Do you think that if a big boss pursues a perfect and beautiful surgery, he will take a big risk regardless of the safety of the patient? He is a big boss. He already has technical confidence.
This donor heart is so beautiful and complete, why must its atrium be connected to the imperfect recipient's atrium? The recipient himself has cardiomyopathy, so why keep the diseased myocardium, waiting for the remnants of the disease to remain in the patient's body?
Looking for an opportunity to act evil? A surgeon takes a scalpel to cut off the disease in the operating room. As long as there is an opportunity, he must cut it as thoroughly as possible.
All classic surgical operations in history show the surgeon's constant pursuit of perfection. It can be said that the older the surgeon, the more he has this "disadvantage" of excellence.
Cao Zhao didn't care about other people's surprise. He was thinking about the two small whirlpools in his eyes under the surgical magnifying glass: Was I being hid something by a bunch of guys again?
(GuoXie member: Yes, touching the teacher’s head is Xie’s strong point.)
