Microcatheter Intrathecal Selective Myelography for Intraprocedural CSF-Venous Fistula Evaluation Pre- and Postembolization.

Recognition of CSF-venous fistulas (CVFs) as a cause of spontaneous intracranial hypotension is increasing. Currently, lateral decubitus digital subtraction myelography and lateral decubitus CT myelography are the mainstays for diagnosing CVFs. Although various methods exist for diagnostic assessment of spinal CVFs, real-time intraprocedural evaluation during endovascular treatment has yet to be described. We report our experience with real-time intraprocedural evaluation of a CVF before and after transvenous embolization using the technique of microcatheter intrathecal selective myelography.
