Endoluminal Visualization of Dural Arteriovenous Fistula Using Virtual Angioscopy.

Virtual angioscopy (VA) has been used for vessel investigation and treatment planning in vascular surgery. To our knowledge, the use of VA in neurointerventional cases has not been demonstrated. We review 2 cases of dural arteriovenous fistula in which VA was used. In 2 patients with dural arteriovenous fistula, VA images were derived from three-dimensional volume-rendered images. Endoluminal visualization of the fistula served as an additional tool that improved anatomic understanding and treatment planning. These cases demonstrate the utility of VA in endoluminal visualization of dural arteriovenous fistula to aid in treatment planning.
