Preventing repeat bleeding in patients with chronic subdural hematoma

Middle Meningeal Artery Embolization Minimizes Burdensome Recurrence Rates After Newly Diagnosed Chronic Subdural Hematoma Evacuation (MEMBRANE)

Not applicable Interventional Unfallkrankenhaus Berlin · NCT05327933

This study is testing if a special procedure to block blood vessels can help adults who have had surgery for chronic subdural hematoma avoid getting bleeding again.

What this trial studies

This study investigates the effectiveness of middle meningeal artery embolization in preventing recurrences of chronic subdural hematoma (cSDH) in adult patients who have already undergone initial surgery. Participants will be randomly assigned to either a control group receiving standard treatment or a treatment group undergoing additional embolization to block small blood vessels in the skull. The procedure involves using X-rays and a contrast medium to guide a fine tube into the affected vessels. The goal is to determine if this additional intervention can significantly reduce the risk of recurrent bleeding.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who have undergone burr hole trepanation for chronic subdural hematoma.

Not a fit: Patients who have not undergone surgical treatment for cSDH or those with acute or other types of hematomas may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly lower the recurrence rates of chronic subdural hematoma, improving patient outcomes and reducing the need for repeat surgeries.

How similar studies have performed: While the approach of embolization in this context is relatively novel, similar studies have shown promise in other vascular conditions, suggesting potential for success.
