Because of the success of stereotactic radiosurgery (SRS) in the treatment of cerebral arteriovenous malformations (AVMs), SRS is being applied to the treatment of carotid-cavernous dural arteriovenous fistulas (CCDAVFs) when these lesions are not accessible endovascularly. We report a patient with a CCDAVF that could not be accessed endovascularly on 2 attempts, whose fistula was successfully closed with SRS, a less invasive modality than endovascular embolization. Further experience with SRS in this role will be necessary to determine its utility.
