Abstract

Transvenous Onyx embolization was recently described as an effective treatment of spontaneous intracranial hypotension caused by CSF-venous fistulas. Patients with CSF-venous fistulas can present with a wide spectrum of clinical and imaging findings, sometimes including spontaneous subdural hematomas, subdural hygromas, or a combination of both. Here, we describe four patients with spontaneous intracranial hypotension complicated by subdural fluid collections caused by CSF-venous fistulas. The patients were treated with transvenous Onyx embolization of their CSF-venous fistulas and transarterial particle embolization of the bilateral middle meningeal arteries, with both procedures performed in a single treatment session. All four patients had clinical improvement and decreased size or resolution of their subdural fluid collections. Based on our findings, we believe that middle meningeal embolization could be a useful adjunct to CSF-venous fistula embolization. A case-control study comparing patients who did or did not undergo middle meningeal embolization will be necessary to validate this supposition.
