Chapter 873 There is light in the heart

To use cerebellar artery bypass surgery, a good understanding of the arteries feeding the cerebellum is necessary.

The blood supply arteries to the cerebellum mainly come from the basilar artery and vertebral artery, which are divided into superior cerebellar artery, anterior inferior cerebellar artery, and posterior inferior cerebellar artery.

The superior cerebellar artery is a branch of the basilar artery and mainly nourishes the upper part of the cerebellum, that is, it supplies the upper part of the cerebellar hemisphere, the upper part of the cerebellar vermis, the anterior medullary velum, etc.

The anterior inferior cerebellar artery mainly nourishes the front part under the cerebellum, and 99% of its origins originate from the basilar artery, but the specific location of its origin sometimes varies.

The posterior inferior cerebellar artery is a branch of the vertebral artery and mainly nourishes the posterior part of the cerebellum, that is, the cerebellar vermis and the lower part of the cerebellar hemisphere.

If you are only studying the diagnosis or treatment of cerebellar infarction, it is enough to have knowledge of these blood supply vessels. However, what is now being treated is hereditary cerebellospinal ataxia, and mastering these is far from enough.

It is necessary to continue to branch along the superior cerebellar artery, anterior inferior cerebellar artery, and posterior inferior cerebellar artery to find out the fine control range of their branches.

In order to conduct more penetrating research on the blood vessels of the cerebellum, Yang Ping made tens of thousands of angiographic pictures of the cerebellum in the system space, and then analyzed the scope of control of each blood vessel, including independent control and cross control.

These angiograms are like tree branches or spider webs. They are connected to each other and form a three-dimensional network.

The blood supply of the human body is very complex and wonderful. Some blood supply is in a network. In this case, blocking a single blood vessel will have little impact on the blood supply. However, some blood supply vessels are single, such as the blood supply of the femoral head. Once blocked or damaged, , the blood supply to this area stops, and the organs or tissues within the supply range will become ischemic necrosis. This is why femoral head fractures can easily cause ischemic necrosis of the femoral head.

In fact, any research work is extremely boring for ordinary people. If the researcher does not have a strong interest in this research work, it will be difficult for researchers to continue the work. Yang Ping has a strong interest in medical research, and even There was an emotional appeal beyond reality, and he was looking at these boring pictures with relish.

Sometimes Yang Ping would draw pictures by himself to help study the distribution of blood vessels. After obtaining a certain understanding of the research, Yang Ping could use the "computer" of the system panel.

With the help of the panel, the analysis of tens of thousands of angiography pictures was quickly completed, and the detailed blood flow distribution map of the cerebellum was outlined.

With these raw data, and then comparing it with Lankoping's head magnetic resonance diffusion image, it is very easy to figure out the distribution of blood vessels.

In those areas with poor blood circulation, it is clear at a glance which blood vessels are problematic and how to build bridges.

However, Lankoping's cerebellar atrophy not only has blood supply disorders and compression, but also has problems with the nerve cells themselves. The problem of the nerve cells themselves cannot be solved for the time being, so it is still unknown how much effect the surgery will have, but it will definitely play a role. effect.

No matter what problems exist in the nerve cells, after the compression is relieved and the blood circulation is improved, the living environment of the remaining normal nerve cells in the cerebellum will at least be improved, and the remaining normal nerve cells can play a greater role, thereby alleviating symptoms.

This is the theoretical basis for Yang Ping's belief that surgery is effective. Any decision he makes has a sufficient scientific basis and is not made randomly.
-

After Lankoping built up his confidence, his mental state was completely different from before.

Especially after hearing that scientific methods can be used to give birth to healthy babies, she feels that life is full of hope and excitement, and she feels that there is light in her heart.

They went to the reproductive center of Sanbo Hospital to inquire. The combination of genetic screening technology and assisted reproductive technology can allow healthy eggs to be combined with sperm through strict selection. Healthy fertilized eggs are artificially cultivated in vitro and then implanted. Lankoping's uterus, which results in a confirmed healthy fetus.

Of course, this method of assisted reproduction is not 100% guaranteed to be successful, and there is also the possibility of failure, such as suspected miscarriage midway. But for Lankoping, this risk is nothing at all, and she can completely accept it. So Fang Liu and Lan Xueping discussed that they would get married when they came back from traveling. After getting married, they began to plan to have a baby. Lan Xueping's belief became more and more firm. Live and live well. Things are really not as bad as he imagined. One day she could have a healthy baby of her own.

Fang Liu didn't know yet that his brothers had bought him a second-hand RV. According to his own plan, he would drive a tricycle, take Lan Koping and Lan Koping's dog with him and travel around the world. China, let’s go see the outside world together.

Fang Liu brought a happy Lan Xueping back from the Reproductive Medicine Center and went to Yang Ping's office. Yang Ping wanted to talk to them again.

A pencil drawing of cerebellar blood flow hangs on the whiteboard in Yang Ping's office.

"This is your cerebellar blood flow map! I have been studying your condition, and I already have a better way than I started - cerebellar vascular bypass surgery."

"Look, the red ones are the arterial blood supply network of the cerebellum, the black ones are the small arteries that have been blocked, and the green ones next to them are the bypasses I am going to make. The number of bypasses you need is four."

"I told you, it's not as bad as you think."

"I have conducted a precise analysis of your current symptoms, and now there are at least half of the normal neuron cells in the cerebellum."

"The pathological changes of cerebellar neuronal cells in this disease are neuronal cell loss and gliosis, and mutant proteins containing polyglutamine are deposited in the nucleus to form intranuclear inclusions."

"That is, there are still about half the number of neuronal cells that do not have the above-mentioned pathological changes. Our surgery is to improve the blood supply of this half of the nerve cells, relieve their oppression, and allow them to gain their due vitality and go better. undertake the work.”

Lan Xueping only knew that the picture was very delicate. She didn't understand much of the other medical knowledge, but she could vaguely understand what Yang Ping said.

She nodded: "Professor Yang, we will follow your arrangements. No matter what the outcome is, we will accept it."

''So Professor Yang must not have any concerns or worries. We are fully mentally prepared. "Fang Liu added.

The statements made by the two of them made Yang Ping feel free of any worries. Yang Ping decided to give it a try in full accordance with his own wishes. Now the theoretical analysis before the operation must be effective. Even if there are inefficiencies or other problems after the operation, Yang Ping The cause can also be found quickly and the surgery can be improved.

In short, with their complete trust, Yang Ping can truly go all out.

"I will do my best, don't worry!"

Yang Ping held Lan Xueping's hand.
