154 MMAE procedures were performed in 121 consecutive patients (median age, 73 years; interquartile range [IQR], 64 to 82); 71.9% male, 60.3% White, 34.7% African American, and 3.3% Asian. 15 (9.7%) were acute, 139 (90.3%) were acute-on-chronic. 88 (57.1%) were unilateral (46 left-sided, 42 right-sided).  33 (42.9%) were bilateral. Two procedure-related complications (1.3%) occurred (facial nerve palsy and femoral artery occlusion). 

At 90 days, follow-up imaging and clinical assessment were available for 74 patients (61.2%), corresponding to 96 embolizations (62.3%).  Complete radiographic resolution of the SDH was observed in 19 embolizations (19.8%). No patients required surgical rescue or were readmitted for SDH. A total of 8 patients (6.6%) expired within 90 days of the procedure from non-neurologic causes. All showed a reduction in the hematoma size and no symptomatic recurrences were observed.
