What question did this study set out to answer?

To evaluate the safety, technical success, and 6-month outcomes of standardized proximal middle meningeal artery embolization using platinum microcoils, and to identify independent predictors for adjunct surgical drainage across hematoma acuity stages.

Overview

Retrospective study demonstrates high technical success and identifies surgical predictors for proximal middle meningeal artery embolization in subdural hematoma, suggesting broad clinical safety.

Key Points

To evaluate the safety, technical success, and 6-month outcomes of standardized proximal middle meningeal artery embolization using platinum microcoils, and to identify independent predictors for adjunct surgical drainage across hematoma acuity stages.
Retrospectively reviewed 100 consecutive adult patients treated with standalone middle meningeal artery embolization (n=53) or embolization with adjunct surgical drainage (n=47).
Stratified baseline traits and 6-month outcomes by acuity: acute (<3 days; n=19), subacute (3-21 days; n=54), and chronic (>21 days; n=27).
Identified independent predictors of adjunct surgical requirement using multivariable binomial logistic regression.
Independent predictors of requiring surgical drainage included higher body mass index (aOR 1.09; 95% CI 1.01-1.17; p=0.028), headache presentation (aOR 2.86; 95% CI 1.03-7.99; p=0.045), and left-sided hematoma location (aOR 0.31; 95% CI 0.10-0.97; p=0.043; AUC 0.745).
Technical success reached 100% across the cohort, with zero periprocedural complications and zero surgical re-evacuations at 6 months (0%).
Fluoroscopy time (p=0.969) and microcoil count (p=0.393) were uniform across all hematoma acuity phases.
