Preoperative middle meningeal artery embolization is associated with reduced reoperation rates in chronic subdural hematoma.

ABSTRACT: BackgroundMiddle meningeal artery embolization (MMAE) has recently emerged as a promising adjunctive therapy to surgical evacuation for patients with chronic subdural hematoma (cSDH). However, the optimal timing of MMAE relative to surgery remains poorly defined. Therefore, this large retrospective cohort study aimed to assess the impact of MMAE timing (preoperative vs. postoperative) on 6-month outcomes in patients with cSDH, focusing on rates of repeat surgery and mortality. We hypothesized that preoperative MMAE would be associated with lower rates of reoperation compared to postoperative MMAE.MethodsAdult patients with nontraumatic cSDH who underwent surgery with adjunctive MMAE were identified using ICD-10 codes from the TriNetX database. A 1:1 propensity score matching approach was u
