Embolization involves plugging up access to the malformation. This technique does not require opening the skull to expose the brain and can be used to treat deep AVMs.
No, but chiari malformation can cause hydrocephalus. In chiari malformation, the hindbrain sits low. This can constrict the normal passageways for CSF (cerebral spinal fluid). If the CSF can't flow properly, it builds up. This is known as hydrocephalus.
