How much of the trimmed piece should be 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 flap is small, the chordae tendineae can be completely preserved. The large flap and small flap here refer to
There are anterior and posterior valves of the mitral valve. The anterior valve has a large area, so it is called a major valve. The posterior valve has a small area, so it is called a minor valve.
The remaining tissue must be sutured and connected to the artificial valve. The part of the artificial valve that is responsible for the connection is called the annulus. In the second operation to remove the broken artificial valve, the first annulus must be completely removed, and it will undoubtedly be removed again.
and damage these original tissues of the human body.
It cannot be said that the doctor who performed the first surgery did not do a good job, which resulted in the second incision turning into a strange shape. It is that the patient's own hyperplastic tissue that grew on the artificial valve was not good, and the doctor could not perform the second surgery.
If you don't cut it carefully, the regular shape of the flap that the surgeon worked hard for the first time will be wasted.
This is something that can't be done without good organization.
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. Student Xie's eyes were sharp, and he pointed out the instructions in his mouth first.
The surgeon managed to preserve the large flap when dealing with the structures under the flap, even though the surgeon had been forced to cut off part of this part during the second surgery.
After judging the surrounding environment of the preserved large subvalvular structure, there is the protruding piece of hypertrophy that Xie Wanying pointed out. The location and structure of this piece of fat flesh are very clever and scheming, like a little devil hiding in the patient's heart.
Inside. If the doctor doesn't do calculations and doesn't think carefully, he won't be able to see the problem at first glance.
It seemed like he saw something fishy. To completely change his mind like Mr.
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 train of thought 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 muscle mentioned in Xie Wanying's words. What is the biggest feature of the vaginal muscle? It is activity.
In other words, what Xie is calculating in his mind is not just the static image of the valve but the dynamic image of the valve.
When the ** muscles pull the valve, it is definitely not just the valve that is moving, but the entire heart is moving. If the muscles near the valve opening are not moving at all, it is definitely not in line with human physiology.
It's like putting something into a hole. Whether the narrow mouth you put something into is a completely fixed dead thing or a moving living thing are completely different things. The limit of movement of the mouth of a dead thing is greater than the range limit of a living thing.
much lower.
The idea to open up is at this point.
"Hmm." The surgeon made a sound, indicating that the idea was open.
"I see."
As Ichigo said these words, Dr. 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 don’t understand it, it doesn’t matter. Dr. Yu knows that there is another way to get around the problem: look at the results.
