This systematic review and meta-analysis evaluated the efficacy and safety of middle meningeal artery embolization (MMAE) in adults with chronic subdural hematoma (cSDH). Analyzing data from seven randomized controlled trials involving 1,889 patients, the study found that MMAE significantly reduced the risk of hematoma recurrence (RR 0.63) and reoperation (RR 0.39) compared to standard therapy alone, without increasing serious adverse events.
Key findings
- MMAE significantly reduced recurrent or residual cSDH (RR 0.63; 95% CI 0.46-0.85).
- MMAE significantly decreased the need for reoperation (RR 0.39; 95% CI 0.28-0.56).
- No increase in serious adverse events was observed with MMAE (RR 0.87; 95% CI 0.72-1.06).
Why it matters
The findings suggest that incorporating MMAE into the treatment regimen for cSDH may enhance patient outcomes by reducing recurrence and the need for additional surgeries, which is crucial given the aging population and high recurrence rates associated with standard treatments.
