Eligibility
Inclusion criteria
Inclusion criteria: Patients with dural arteriovenous fistulas treated with gamma knife between January 1, 1997 and December 31, 2016. If a patient has 2 or more fistulas; - If 2 or more lesions were treated with gamma knife, they should be registered as independent lesions only if they were located at an adequate distance from each other (farther than each other's 20% isodose line). - If one of them was treated with gamma knife, the one should be registered; however, presence of the other lesions should also be clarified. - Data on patients with 2 or more fistulas should be only used for the analyses for obliteration, because the analyses on hemorrhage and complications would become inappropriate as those rates of patients with 2 or more fistulas might be different by nature from patients with only one fistula.
Exclusion criteria
Exclusion criteria: 1. Patient with a history of radiation therapy to the brain. 2. Patient without any follow-up image study. 3. Patient under 20 years.
