What are the advantages /disadvantages of stereotactic radiosurgery for avm?

Noninvasive: Advantage: noninvasive disadvantage: it can take several months for it to work, several sessions, risk of causing a cancer, etc. Depending on the size, location, symptoms, etc. Embolization, surgery, stereotactic radiosurgery are some of the ways to treat avm. A consultation with neurosurgeon, neuroradiologist, radiation oncologist can determine, what is the best way to treat your condition.

AVM : I'm not an expert in treating these disorders, but gamma knife can be an option for avms under a certain size with specific characteristics in eloquent areas of the brain where surgical treatment is not an option. One can also make the argument for small surgical lesions in non eloquent areas but gamma knife treatment window is longer 2 years sometimes and you go with 2 years of rupture risk.

...: Advantages: no risk of surgery. Less damage to surrounding brain. Less damage to brain traversed to get to the avm during surgery. Less pain. Disadvantages: takes time for the risk of bleeding to drop. Avm may not be obliterated. It may require a second radiosurgery, later on.
