Liquid or particle embolization was excluded. Selection criteria for adjunct versus stand-alone MMAE were based on clinical judgement. Outcome measures included were a decrease in size of the cSDH, decreased size &gt;50%, midline shift, reoccurrence or progression, retreatment, clinical stability or symptom improvement, and procedure-related complications.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Twenty-three patients\/31 hemispheres received MMAEs (eight bilateral and 15 unilateral) with SwiftPAC coils. Twenty-two patients (96%) had clinical and radiographic follow-up (median 54 days), and one patient was lost to follow-up. Sixteen (69.6%) MMAEs were performed as an adjunct to surgical drainage; seven (30.4%) were stand-alone MMAEs. No procedural-related complications were observed. Clinical stability or symptom improvement at follow-up was demonstrated in 95.4% of patients (21\/22). Radiographic improvement at follow-up was demonstrated in 93.3% (28\/30). Nineteen (63.3%) cSDHs had a decrease in size &gt;50% and nine cSDHs (30%) demonstrated complete resolution. One patient required retreatment for recurrence.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>MMAE with SwiftPAC coils can be performed with a high safety profile and good radiographic and clinical outcomes.
