Dural arteriovenous fistulas are characterized by abnormal arteriovenous shunting localized to the pachymeninges. Fistulae venous drainage is essential to their classification, symptomatology, and treatment. Endovascular therapy is rapidly progressing to an adjunct or even alternative treatment to microsurgical resection. Several techniques, such as transarterial or transvenous embolization with metallic coils, NBCA, or Onyx, have been used successfully in several studies. The long-term clinical and radiographic outcomes of endovascular therapy for the treatment of dural arteriovenous fistulas are satisfactory, and future studies are underway for the refinement of these techniques.
硬脑膜动静脉瘘的特征是位于硬脑膜的异常动静脉分流。瘘静脉引流对于其分类、症状和治疗至关重要。血管内治疗正在迅速发展成为显微切除手术的辅助治疗甚至替代治疗。一些技术，如经动脉或经静脉栓塞用金属线圈、NBCA 或 Onyx，已经在几项研究中成功应用。血管内治疗硬脑膜动静脉瘘的长期临床和影像学结果令人满意，目前正在进行进一步研究以完善这些技术。
