What this trial studies

This observational study aims to gather data on patients diagnosed with spontaneous intracranial hypotension (SIH) who have confirmed cerebrospinal fluid-venous fistulas. By utilizing imaging techniques such as digital subtraction myelography (DSM) and CT myelography (CTM), the study seeks to assess the efficacy of paraspinal vein embolization as a treatment option. The findings will help inform the design of future clinical trials targeting this condition. Participants will be monitored for their responses and outcomes over a specified follow-up period.

Who should consider this trial

Good fit: Ideal candidates include patients diagnosed with SIH who have imaging-confirmed CSF-venous fistulas.

Not a fit: Patients who are pregnant, breastfeeding, or have contraindications to the procedure will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment options for patients suffering from spontaneous intracranial hypotension.

How similar studies have performed: While this approach is being explored, the efficacy of paraspinal vein embolization for SIH has not been extensively tested in prior studies.
