Cerebrovascular malformations can be cured, but the prerequisite for cure is related to the type, size and location of the cerebrovascular malformation as well as the treatment modality. And it is important to choose the best surgical procedure and to clarify the changes in the condition so that the root cause of the cerebrovascular malformation can be treated. Cerebrovascular malformations are divided into cavernous hemangiomas, arteriovenous malformations and capillary dilation. For cerebral arteriovenous malformations, a small percentage of patients can be cured by embolization, while most patients need surgery or radiation therapy. It is generally believed that a malformation may be cured if the malformed mass disappears completely or shrinks by more than 95%. However, for the residual malformed vascular masses, there is little tendency for them to shrink or even expand over time after treatment. For example, capillary vasodilatation is an occult vascular malformation and will only be diagnosed by clearing the hematoma and taking specimens for pathology as appropriate when a large hematoma occurs; a few low-flow dural arteriovenous fistulas may also be self-closing. Then there is no cure for cerebral surface angiomatosis, which is mainly to control symptoms without main. Therefore, for cerebral vascular malformation, the first thing is to improve the examination to clarify the fundamental changes of the disease, and the second point is to actively carry out relevant treatment to prevent further aggravation of the disease. At present, about 80%-90% of the patients can be cured clinically.
