O-021 Concurrent middle meningeal artery embolization for treatment of chronic subdural hematomas

This study provides evidence from a multi-institutional cohort that performing concurrent MMAe in the perioperative period as an adjunct to surgical evacuation is a safe and effective means to reduce surgical recurrence in patients with NASHs.Abstract O-021 Table 1Procedural details of 145 patients (149 NASHs) who underwent concurrent MMAe Characteristic Value (range or%) Antiplatelet/anticoagulation use Antiplatelet 46/147* (31) Anticoagulant 29/148* (20) Both 9/148* (6) Prior SDH evacuation 38/149* (26) Perioperative platelet count < 100K 8/148* (5) Procedure details Anesthesia General 63/149* (42) MAC 57/149* (38) Conscious sedation 29/149* (19) Embolisate material Particles 10/145* (7) Particles + coils 58/145* (40) Liquid 60/145* (41) Liquid + coils 11/145* (8) Coils 6/145* (4) Radial access 51/149* (34) Abstract O-021 Table 2Radiographic characteristics of 149 NASH that underwent treatment with concurrent MMAe Characteristic Value (%) Left side 76/148 (51) Bilateral 4/148 (2.7) Subdural membranes present 103/118 (87) Median MMA size (mm) 2 Dangerous collaterals 9/102 (9) Median SDH width (mm) Baseline 18 Post-evacuation 12 90 days 6 Abstract O-021 Table 3Outcomes of 149 NASHs that underwent concurrent MMA embolization Outcome variable Value (% or range) Unsuccessful procedure 1/149 (0.7) Median FU (days) 60 Range (1 - 380 days) mRS score median preoperative (range) 1 (0-5) median 90 days (range) 0 (0-6) mRS score worse at last FU 9/70 (13) mRS score same at ...
