Outcome Of Intracranial Davf With Retrograde Leptomeningeal Drainage After GksMei Hsiu Wu1, David Hung-Chi Pan2, Wen-Yuh Chung1, Wan-Yuo Wayne GUO3, Kang-Du Liu1, Cheng-Ying Shiau1, Ling-Wei Wang11Taipei Veterans General Hospital, Taipei, Taiwan 2Taipei, Taiwan 3Taipei Veterans General Hospital and Yang-Ming University Keywords: dural arteriovenous fistula, gamma knife, vascular malformation, outcome, arteriovenous fistulaInteractive ManuscriptAsk Questions of this Manuscript: What is the background behind your study? What is the purpose of your study?To further evaluate the efficacy of GKS in treating DAVFs with retrograde leptomeningeal drainage and to identify the possible unward events after treatment. Describe your patient group.121 patients with intracranial dural AVFs and retrograde leptomeningeal venous drainage had received gamma knife radiosurgery in a 15 year span (1994 to 2008). There are 73 patients with cavernous sinus lesion, 48 with lesions in other sites. Describe what you did.Lesion locations, Cognard classification, MR findings, treatment, clincal and image follow up were recorded. Actural cure rate was plotted using Kaplan-Meier method. Untoward clinical events were classifed into persistent venous hypertension, paradoxical deterioration due to occlusive hyperemic change, and others. Describe your main findings.This question was not answered by the author Describe the main limitation of this study.This question was not answered by the author Describe your main conclusion.This question was not answered by the author Describe the importance of your findings and how they can be used by others.This question was not answered by the author To further evaluate the efficacy of GKS in treating DAVFs with retrograde leptomeningeal drainage and to identify the possible unward events after treatment. 121 patients with intracranial dural AVFs and retrograde leptomeningeal venous drainage had received gamma knife radiosurgery in a 15 year span (1994 to 2008).
