Spontaneous closure of non-cavernous sinus dural arteriovenous fistulas: A case series and systematic review of the literature

Both high- and low-risk cranial dural arteriovenous fistulas (DAVFs) can close spontaneously. Our institutional review found that 9 of 68 patients with non-cavernous sinus DAVFs showed spontaneous closure. An analysis combining data from our patients and those identified in a systematic literature review indicated that 36% of spontaneous closures occurred within 3 months from the initial diagnosis and the most frequent predisposing factor was angiography.
