Background

Middle meningeal artery embolization (middle meningeal artery embolization) has emerged as a promising adjunctive treatment for chronic subdural hematoma (cSDH); however, the efficacy and safety of adjunctive middle meningeal artery embolization compared with surgery alone remains uncertain.

Methods

We systematically searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials from inception through June 2026.

Results

adding MMA embolization to surgery lowered the odds of hematoma recurrence

OR 0.31 (95% CI 0.16 to 0.59)

CI excludes the null - significant

More results

The mean age of participants ranged from 64 to 77 years, and most participants were male.

No significant differences were observed in all-cause mortality (OR, 0.91 [95% CI, 0.24-3.42]), good functional outcome (OR, 1.23 [95% CI, 0.23-6.42]), or overall adverse events (OR, 1.02 [95% CI, 0.35-2.91]) between the groups.

Conclusion · 1 of 2

In this updated meta-analysis of randomized controlled trials, adjunctive middle meningeal artery embolization significantly reduced recurrence without increasing complication rates.

Conclusion · 2 of 2

Although no significant improvements were observed in functional outcomes or mortality, these findings support adjunctive middle meningeal artery embolization as an effective and safe strategy for improving disease control in patients undergoing surgical treatment for cSDH.
