Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include patients diagnosed with chronic subdural hematoma who present to the emergency room or neurosurgical clinic.
✕Probably not a fit
Patients who cannot provide informed consent or have a known allergy to the embolic agent will not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study evaluates the safety and effectiveness of embolizing the middle meningeal artery as a treatment for chronic subdural hematoma (CSDH). Patients presenting with CSDH to the emergency room or neurosurgical outpatient clinic will be screened for enrollment. Those who consent will undergo the embolization procedure, and their outcomes will be monitored through follow-up CT scans and clinical assessments at 1, 3, and 6 months post-treatment. The study aims to determine if this approach reduces the recurrence rate of CSDH, especially in patients at higher risk of recurrence.
Why it matters
Potential benefit: If successful, this treatment could significantly reduce the recurrence of chronic subdural hematoma in patients.
How similar studies have gone: While embolization techniques have been explored in other studies, this specific approach for chronic subdural hematoma is relatively novel.
