The place where cerebrospinal fluid is produced is the lateral ventricle. In addition to the lateral ventricle, there is a third ventricle and a fourth ventricle.

The ventricle system can be called the "pool" that contains cerebrospinal fluid. The cerebrospinal fluid is from the lateral ventricle to the third ventricle and then to the fourth ventricle.

How cerebrospinal fluid is recovered through arachnoid particles and is recycled into the venous system.

The above cycle sounds like a very closed environment.

That's right. The blood-brain barrier that we often hear includes three barriers: blood-brain, blood-cerebrospinal fluid, and cerebrospinal fluid-brain barrier. It can be seen that the cerebrospinal fluid environment is so closed.

How to specifically deconstruct "closed" and "barrier" come from? It is more complicated, with a cytology interpretation and a mechanical physics interpretation.

Let’s talk about the current patient, hydrocephalus and hydrocephalus are the area of ​​“water” in the brain and there is too much cerebrospinal fluid. There is too much cerebrospinal fluid, which means that there may be problems with the recycling mechanism. The circulation path may be hindered, and the “water” body circulates smoothly. As a result, the “pool” containing cerebrospinal fluid will naturally expand.

Clinical manifestations are that CT shows dilation of the ventricular system and or subarachnoid space, and compression of normal brain tissue is often accompanied by brain atrophy. What are the symptoms of brain atrophy? I just mentioned that the symptoms of cerebellar atrophy will only be more serious than cerebellar atrophy.

Typical symptoms: adult patients with headache, nausea and vomiting, abnormal mental drowsiness and mania, ataxia and incontinence, etc.

Given that we have talked about a lot of problems with cerebrospinal fluid, we can know that if it is hydrocephalus caused by other diseases, such as tumors, it may be solved with a surgical knife.

However, the common hydrocephalus in clinical practice may not be clearly visible. If more complex secretion problems are involved, it is natural to use internal medicine to solve the problem of surgery.

If surgery does not cure the root cause, it is afraid that it will recur frequently, so why bother the patient to get a slap in vain?

It is necessary to use surgical methods to clarify the cause that can be solved by surgery.

For example, three ventricular undersonic surgery is designed to cause circulatory obstruction in the path from the third ventricle through the midbrain water conduit to the fourth ventricle. A hole is directly made in the third ventricle to direct the cerebrospinal fluid to the anterior ventricular pool.

If the cause is not determined or the cause cannot be solved by surgical means, the surgery also has a conservative surgical treatment plan, which is the most commonly known as cerebrospinal fluid shunt.

Time is tight, so a team of neurosurgeons first entered the ward to check the rounds.

Dr. Jin was waiting outside, waiting for them to check in to see their ward.

Starting from the countdown bed, I found that the patient in bed 23 Dr. Jin's friend was a woman in her thirties and forties. It was initially judged that it might be hydrocephalus caused by some kind of infection, because no other causes were found. However, after the cerebral arteriovenous malformation was found, it was hard to say which one was the first and who was later.

The patient's current condition is relatively serious and he has already developed drowsiness.

Here are the junior brothers and sisters.

During the rounds, Huang Zhilei asked his juniors to go up and do a neurosurgery examination for the patient, and took it as an on-site examination.

For patients with hydrocephalus, according to what students Pan and the others thought, they could not tell what the hydrocephalus was like just looking at the patient's head.
