To perform a retrospective chart review of surgically treated patients with spinal dural arteriovenous fistula (SDAVF), a rare disease but the most common vascular malformation of the spine, focusing on clinical characteristics and functional outcome during long-term follow-up. ⋯ Surgical treatment of SDAVFs is safe and effective and leads to an improvement of neurologic symptoms in most patients. Surgical treatment of SDAVFs also provides long-term stability.

A recent study reported on the relatively safe area in the frontal lobe for performance of neurological interventions; however, no study on the posterior safe area has been reported. In this study, using diffusion tensor tractography, we attempted to identify the safe area in the parieto-occipital lobe in healthy subjects. ⋯ According to our findings, the safe area was located in the posterolateral portion of the parieto-occipital lobe in the shape of a triangle. However, we found no safe area in the deep white matter around the lateral ventricle.
