When the gentle student Pan saw that Student Xie did not want to say that, he took the initiative to explore the path ahead: "I think the most critical part is the right place."

If Liuguang in Cao Yong's eyes nodded to his junior brother's answer, it seems that many junior brothers are also talented.

In a brief summary of the words of Student Pan, it refers to the inappropriate places during the organ transplantation process. Doctors may use clever methods to change to the right one.

"Yingying, what do you think?" Pan Shihua asked Xie's high opinion.

Senior Brother Cao and Wei looked over and seemed to want to hear something she said. Xie Wanying said: "Where is the limit of suitable technology, and where is the upper limit of organ transplant surgery possible."

This is a further academic interpretation of the words of Pan.

Wei and Pan's eyes seemed to have been lit up by the little stars. Cao Yong's mouth couldn't close.

How to understand what Mr. Xie said?

Let’s talk about the liver transplant surgery I have seen before. At that time, Xie participated in the process and made suggestions. The difficulty of the doctors in the operation is that the donor liver is too big and it is not appropriate to cut it into small amounts. This is a suitable problem.

The proportion of donor receptors in all organ transplant surgeries has always been a basic threshold.

There are such technical difficulties in liver transplant surgery, which are also found in heart transplant surgery.

Is it suitable for liver transplantation, if the heart donor is larger and the heart is smaller? Student Xie told reporter Li that the proportion of the heart of the pediatric donor can be as large as 2.5 times the size of the recipient's original heart.

Regarding this crux, as long as you have some common sense of anatomy, you can't be like the liver. The two organs of the liver and the heart have different morphological, functional structures.

The overall structure of the heart is closely related to its function. The liver is not, and the function of the liver mainly depends on the liver tissue. This causes a donor liver to be cut into two for use with two recipients. How is the heart possible? The proportion of the heart to the donor receptor is really stricter than that of liver transplantation. Here I will talk about a cold knowledge point. If you want to transplant liver, you don’t have to worry about the donor being too small. On the contrary, as student Xie said, the proportion of the heart in the pediatric donor should not be less than 0.9 of the original heart of the recipient. This indicates the acceptance of the small donor ratio. Heart transplantation is much lower than that of the liver transplantation.

Why is this?

The main function of the heart is output to recover blood throughout the body. The donor is not afraid of being larger because many patients who need to undergo heart transplantation have heart disease, causing the heart to expand and the volume of the heart to become larger. The size of the place where the heart is accommodated will be larger. Of course, it cannot be outrageously large, as this will also cause secondary hypertension and other problems after the operation.

In contrast, the problem of too small donor is difficult to solve: the heart discharge is low. Many heart disease patients die of end-stage sleepiness. If the heart transplant fails to solve this important problem, the result is likely to be a vague transplant.

In terms of clinical practice, it becomes: young children should try to choose older donor hearts. Female patients should choose male hearts. Male patients should accept the hearts of patients with too much weight less than their own, so be cautious.

These are exactly what Student Xie pointed out that the "suitable" technology limit determines the limit of organ transplant technology, and are all difficulties that need to be solved in surgery.

The threshold of the proportion alone is higher than that of liver transplantation. Heart transplantation is definitely more difficult than liver transplantation, otherwise I would be sorry for the two major surgical specialties.
