Dural Arteriovenous Fistula:Indications and Outcomes

Point

・硬膜動静脈瘻は，静脈流出パターンで分類される．

・皮質静脈逆流，出血，NHNDの有無により治療介入を検討する．

・Onyx^TMが治療適応となることで，経動脈的塞栓術の治療が進歩した．

　The diagnosis of dural arteriovenous fistulas（DAVF）has advanced with the development of imaging techniques. The indication for treatment of DAVF is generally based on classification according to the venous drainage pattern, which determines whether the presentation is benign or aggressive. In recent years, with the introduction of Onyx, transarterial embolization has been increasingly used, and outcomes have improved, although some conditions are more suitable for transvenous embolization. It is important to select an optimal approach based on location and angioarchitecture. Since DAVF is a rare vascular disease with limited evidence, further validation of clinical results is needed to provide more established treatment guidelines.
