Minimally invasive treatment for chronic subdural hematoma using cyanoacrylate embolization

LEADH: Efficacy of a Minimally Invasive Therapy Adjuvant to the Standards of Care by Cyanoacrylate Embolization : Liquid Embolic Agent for the Treatment of Chronic subDural Hematoma a Randomized Control Study

Not applicable Interventional University Hospital, Brest · NCT05374681

This study is testing if adding a new, less invasive treatment using glue to standard surgery can help people with chronic subdural hematoma have better outcomes and lower chances of the condition coming back.

What this trial studies

This clinical trial evaluates the efficacy of cyanoacrylate embolization as an adjuvant therapy for patients with chronic subdural hematoma (CSH) requiring surgical intervention. Participants will be divided into two groups: one receiving standard surgical management with additional embolization of the middle meningeal artery, and the other receiving only standard surgical management. The study aims to assess the recurrence rates of CSH and overall patient outcomes using specific scoring systems at two and six months post-treatment. The trial is designed to provide insights into the effectiveness of this minimally invasive approach compared to conventional methods.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a chronic subdural hematoma greater than 10 mm localized to the convexity of the brain.

Not a fit: Patients with severe pre-existing disabilities, life expectancy under six months, or contraindications to angiogram procedures will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce the recurrence of chronic subdural hematomas and improve patient outcomes.

How similar studies have performed: While there are ongoing studies on chronic subdural hematomas, the specific use of cyanoacrylate embolization as an adjuvant therapy is relatively novel.
