How much of the trimmed slice is retained depends on the specific case. In some patients, the large flap is completely cut off, leaving only the root of the vaginal muscle. If the small flap is used, the chordae and chordae can be completely preserved. The large and small valves here refer to the anterior and posterior valves of the mitral valve. The front valve has a large area and is therefore called a large valve. The area of the posterior valve is small, so it is called a small valve.
The remaining tissue must be sutured and connected to the artificial valve. The part of the artificial valve that connects is called the annulus. In the second operation to remove the broken artificial valve, the first valve annulus must be completely removed, which will undoubtedly re-excise and damage these original human tissues.
It cannot be said that the surgeon did not do a good job during the first operation, which resulted in the second operation turning into a strange shape. It was because the hyperplastic tissue that the patient had grown on the artificial valve was not good, so the surgeon had to cut it into pieces during the second surgery, and the regular shape of the flap that the surgeon had worked so hard to create had to be scrapped.
This is something that can't be helped, and bad organization will have to do it.
After the incision, if the surgeon's idea of organizing the flap is judged again, it will be helpful to trim the original human tissue and suture it again. Xie's eyes were sharp, and he pointed out that the surgeon in the first operation had preserved the large flap even though the surgeon in the second operation had been forced to resect this part. Drop part.
After judging the surrounding environment of the preserved large subvalve structure, there was the protruding hypertrophy pointed out by Xie Wanying. The location and structure of this thick piece of meat are very clever and scheming, like a little devil hiding in the patient's heart. If a doctor doesn't do calculations and doesn't think carefully, he won't be able to see the problem at first glance.
It seems that something is fishy. To completely change the idea like Mr. Xie did, you need to think about it a few more times. Doctor Yu was a little confused by this. He didn't dare to look at the surgeon with questioning eyes for fear of being scolded, so he could only look at Senior Shi Lei beside him.
Shi Lei remained calm. Ever since Classmate Xie opened his mouth, he kept his mouth tighter and more like a dumb stone.
Having almost rolled over the car, he knew very well that Xie's thoughts needed to be pondered over and over again.
How this muscle affects the valve orifice is difficult to understand just by looking at it intuitively. It must be combined with the vaginal muscles mentioned in Xie Wanying's words. What is the biggest feature of the ** muscles? It is activity.
In other words, what Xie is calculating in his mind is not just the static state of the valve but the dynamic image of the valve.
When the ** muscles pull the valve, it is certainly not just the valve that is moving, but the entire heart. If the muscles near the valve opening don't move at all, it's definitely not in line with human physiology.
Just like when you put something into a hole, it is completely different whether the narrow hole you put the thing into is a completely fixed dead object or a movable living thing. The limits of mouth movement of dead creatures are much lower than the range limits of living creatures.
The idea to open up is at this point.
"Hmm." The surgeon made a sound, indicating that his mind was open.
"I see."
Following these words from Yishutong, Doctor Yu lowered his head: his brain was almost spinning to death before he could turn around.
It's really difficult to be a doctor and have a quick mind.
Although I can’t figure it out, it doesn’t matter. Dr. Yu knows that there is another way to get around the problem: look at the results.
