Abstract
Recognition of cerebrospinal fluid-venous fistulas 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 cerebrospinal fluid- venous fistulas. Although various methods exist for diagnostic assessment of spinal cerebrospinal fluid-venous fistulas, real-time intraprocedural evaluation during endovascular treatment has yet to be described. We report our experience with real-time intraprocedural evaluation of a cerebrospinal fluid-venous fistula before and after transvenous embolization using the technique of microcatheter intrathecal selective myelography.ABBREVIATIONS: CVF = cerebrospinal fluid-venous fistula; CTM = computed tomography myelography; DSM = digital subtraction myelography; mISM = microcatheter intrathecal selective myelography.
