ABSTRACT
Background Cerebrospinal fluid-venous fistulas (CVFs) are one of the less common etiologic causes of spontaneous intracranial hypotension. CVFs are most commonly treated with open surgical ligation and have reportedly not responded well to percutaneous treatments. Purpose To study treatment outcomes of CT-guided fibrin glue occlusion for CVFs. Materials and Methods Retrospective review of medical records from two institutions was performed for all patients with CVFs who underwent CT-guided percutaneous fibrin glue occlusion from March to October 2020. CVFs were assessed for resolution or persistence at posttreatment decubitus CT myelography (CTM). Pre- and posttreatment brain MRI scans were reviewed for principal signs of spontaneous intracranial hypotension. Clinical symptoms were documented before and immediately after therapy, and the current symptoms to date after fibrin glue occlusion were documented. Results CT-guided fibrin glue occlusion was performed in 13 patients (mean age, 62 years ± 14 [standard deviation]; eight women) with CVFs. Ten of 10 patients who underwent final posttreatment decubitus CTM examinations showed CVF resolution. All 13 patients showed improvement on posttreatment brain MRI scans. All 13 patients are currently asymptomatic, although three patients were asymptomatic before fibrin glue occlusion. Conclusion CT-guided fibrin glue occlusion is an effective treatment for patients with cerebrospinal fluid-venous fistulas (CVFs). Direct fibrin glue administration within the CVF may be one of the key factors for success. Further studies are needed to determine the long-term efficacy of this treatment. © RSNA, 2021.
