Recurrence and Coniglobus Volumetric Resolution of Subacute and Chronic Subdural Hematoma Post-Middle Meningeal Artery Embolization

Objective: To study the efficacy of middle meningeal artery (MMA) embolization for treatment chronic subdural hematoma (SDH) and characterize its post-embolization volumetric resolution. Methods: Ten patients diagnosed with 13 cSDH underwent MMA embolization. SDH volumes were measured from time initial discovery on imaging to pre-operative, post-operative, short-term long-term follow-up. Time between procedure obliteration was also measured. Volumetric analysis done using coniglobus formula, recurrence rate as well resolution timeline defined best-fit models. Results: Out 10 patients, five recurrent lesions, three bilateral seven unilateral cSDH. Average median pre-operative 105.3 cc 97.4 cc, respectively. Embolization average performed 21 days after discovery. Sixty percent had concurrent antiplatelets or anticoagulation use. Forty primary therapy. Recurrence not seen in any treated There no peri- post-operative complications. Five experienced complete near-complete obliteration, while those partial showed a composite 75% reduction 45 days. Post-embolization, followed an exponential decay curve over independent volume. Conclusion: contributed marked volume post-operatively can be used curative therapy SDH.
