Chapter 2160 [2160] Ideas open

How much of this trimmed flaky remains depends on the specific case. In some patients, the large flap is completely cut off, leaving only the root of the muscle, and the small flap can completely retain the chordae tendineae. The large valve and the small valve here refer to the anterior and posterior valves of the mitral valve. The front lobe has a large area and is therefore called the large lobe. The area of ​​the back lobe is small, so it is called a small lobe.

The remaining tissue should be sutured to the artificial valve. The part of the prosthetic valve that engages is called the annulus. In the second operation to take out the broken artificial valve, the first valve annulus must be completely removed, which will undoubtedly remove and damage these original human tissues.

It cannot be said that the first surgeon did not do well in the operation, resulting in a strange shape after the second cut. However, the proliferative tissue grown on the artificial valve by the patient itself is not good, so the second surgery doctor had to cut it out, and the regular valve shape that the first surgery doctor worked hard to come up with had to be abolished.

This is impossible, bad organization must be done.

After the    incision, if you can judge the idea of ​​the first surgeon's arrangement of the valve opening, it is beneficial to trim the original human tissue and suture again. Xie's eyes were sharp, and the instructions in his mouth first pointed out that the first operation doctor's treatment of the sub-valvular structure was to retain the large valve, even if the second operation doctor had been forced to cut this part again. part off.

After making judgment on the surrounding environment of the structure under the large valve that was retained, there was the protruding hypertrophy pointed out by Xie Wanying. The location and structure of this thick piece of meat are ingenious and scheming, like a little devil hiding in the patient's heart. If you don't do calculations and think about it carefully, you can't see the problem at first glance.

It seems to be a little strange. To completely turn your thoughts out like Xie did, you need to circle your mind a few times. Dr. Yu was a little dazed by this, and did not dare to look at the chief knife with questioning eyes for fear of being scolded, so he could only look at the senior Shi Lei beside him.

Shi Lei remained calm, and since Xie opened his mouth, he closed his mouth even more like a stone that couldn't speak.

He almost overturned the car, and he knew very well that Xie's ideas needed to be pondered over and over again.

How this muscle affects the valve opening is difficult to understand just by looking at it intuitively. It must be combined with the ** muscle that Xie Wanying said. **What is the biggest feature of this muscle? It is activity.

means that what Xie is calculating in his mind is not only the static state of the valve, but the dynamic map of the valve.

**When the muscle pulls the valve, it is definitely not just the valve that moves, but the whole heart moving. If the muscles near the valve orifice are called not moving at all, it is definitely not in line with human physiology.

For example, when you put something into an opening, the narrow opening into which you put something is a completely fixed dead thing or an active living thing is completely different. The limit of the mouth energy change of the dead is much lower than the limit of the range of the living.

The idea to open is at this point.

"Mmmm." The chief knife made a sound, indicating that the idea was opened.

"I understand."

Accompanied by the words of Yisuke, Dr. Yu lowered his head: his brain has not turned around yet, it is about to die.

Being a doctor is too hard to think about.

Although I don’t understand it, it’s okay, Dr. Yu knows that there is another way to turn the brain around: look at the results.
