Single-Session Middle Meningeal Artery Embolization With Concomitant Evacuation Surgery for Chronic Subdural Hematomas: A Multicenter Assessment of Feasibility, Safety, and Efficacy.

Background And Objectives: Middle meningeal artery embolization (MMAE) is a safe and efficacious adjunct to surgical evacuation for symptomatic chronic subdural hematoma (cSDH). We evaluated the concomitant performance of MMAE with surgical evacuation in a single anesthetic session rather than a staged approach.

Methods: In this retrospective, multicenter cohort study, patients with cSDH who underwent MMAE and surgical evacuation during 1 anesthetic session from January 2020 through August 2024 were included.
