Spetzler-Martin grade I-III AVMs can often be eradicated by having an acceptably reduced operative possibility. Spetzler-Martin grade IV and V AVMs can even be removed surgically, but because of the surgical hazard, a complement of stereotactic radiosurgery must be reviewed for partial or finish AVM obliteration. Spetzler-Martin quality VI AVMs can gain from stereotactic radiosurgery as a first-line treatment or as being a supplement to preoperative embolization.
