Effectiveness of subdural evacuating port system (SEPS) and middle meningeal artery embolization (MMAE) for chronic subdural hematomas – a multicenter experience
Background Craniotomy for subdural hematoma (SDH) in elderly patients with comorbidities can be challenging. The Subdural Evacuating Port System (SEPS; Medtronic, Minneapolis, MN) offers a less invasive alternative, while middle meningeal artery embolization (MMAE) has shown effectiveness in preventing SDH recurrence. We evaluated the combined effectiveness of SEPS+MMAE for chronic SDH (cSDH) treatment. Methods Retrospective database reviews were conducted. Demographic, comorbidity, procedural, and outcomes data were analyzed. cSDH resolution was tracked by measuring hematoma volumes on noncontrast computed tomograms pre-SEPS+MMAE, 24–48 hours post-SEPS+MMAE, and 6–8 weeks afterward (follow-up-SEPS+MMAE). Results Our study included 114 patients (median age: 77 years (interquartile range (IQR): 69–83 years); men: women=74:40) with 134 cSDHs treated with SEPS+MMAE were included. Median pre-SEPS+MMAE cSDH volume was 122.9 mL (88–152.4 mL) with midline shift of 6 mm (3.4–9.5 mm). Most MMAE
