Abstract
= .40). The unmatched analysis for order and timing was underpowered to detect differences in reoperation below 11.6% and 14.6%, respectively, and in technical success below 8.5% and 11.3%, respectively, and the matched analyses were more underpowered. Conclusion The cohort did not show statistically significant differences in technical success or reoperation rates based on the timing and order of MMAE relative to surgical evacuation, although larger studies are needed to confirm these observations and rule out smaller, clinically meaningful differences. © RSNA, 2025
