What Is a Cerebral Shunt?

Brain tumors are new organisms that grow in the cranial cavity. They are also called intracranial tumors and brain cancers. They can originate in the brain, meninges, nerves, blood vessels, and brain attachments, or they can be formed by other tissues or organs in the body. , Most can produce headaches, intracranial hypertension and focal symptoms. The incidence of brain tumors is about 1.9 to 5.4 per person (year · 100,000), accounting for 1% to 3% of various tumors throughout the body.

Brain tumor

Brain tumors are

In real life, most people lack understanding of brain tumors, and many patients have lost their lives without timely early diagnosis and treatment. Therefore, people should pay attention to them. The top 10 early signals of brain tumors are described below: (1) Headache: It is more severe in nature. It often occurs in the early morning and is sometimes awoken during sleep. However, the headache will gradually ease or disappear after getting up slightly.
(2) Vomiting: due to increased intracranial pressure,

[Cause and tissue type]

1. The cause of brain tumors, like other tumors, is not completely clear. There are related factors such as viral infections, carcinogens,

For the present

Treatment guidelines:
1. Surgical treatment: brain tumors that are more benign in nature, have more complete capsules and are easier to peel off, and have a shorter course of disease, have greater hope for surgical cure. However, palliative surgery is possible for highly malignant or other metastatic cancers, such as partial tumor resection, decompression, ventriculoventricular fistula, and ventricular vein shunt surgery.
2. Radiation therapy: At present, radiotherapy is also called stereotactic radiation, and a full range of rotary radiotherapy technology is used to make the tumor shrink and even disappear after being exposed to radiation in multiple directions, achieving the same effect as surgery.
3 Chemotherapy: Photodynamic chemotherapy is effective in treating brain malignancies. Other chemotherapy regimens are: BCNU-DA regimen: BCNU90mg / m2, I · V, Day 1; DAG70mg / m2, I · V, Day 1; Repeat every 5 weeks. For brain tumors and brain metastases. AVC regimen: ADM45mg / m2, I · V, the first day; Vm60mg / m2, I · V, the second and third days, for 5 consecutive hours; CCNU60mg / m2, P · O, the fourth to fifth days, every 35 Days are repeated for brain gliomas.

Recently, surgery for chemotherapy of intracranial tumors at home and abroad mostly uses surgery, chemotherapy, radiotherapy, X-knife, -knife, etc., but most of them are difficult to cure. Malignant tumors have a short course of disease and rapid development. Sensitivity, recurrence sooner or later, tumors growing in important parts of the brainstem, thalamus, etc. are difficult or inoperable. Tumors after X-knife, radiation and other treatments can shrink or control growth for a short time after the tumor no longer grows Recurrence, benign tumors have a longer course, slow growth, and complete resection is not easy to relapse. However, brain tumors growing in important parts such as the brainstem can only be partially or largely resected. After surgery, the tumor will relapse and reoccur. The average survival rate of growth, intracranial malignant tumors after radiotherapy and chemotherapy is less than one year. Surgical benign intracranial tumors such as benign gliomas, pituitary tumors, craniopharyngiomas, and cholesteatoma cannot be easily removed. Surgery and radiation are not likely to completely kill the tumor, so most patients will still relapse after surgery.
