Intergroup comparisons for surgical metrics used the Mann\u2013Whitney U test.Results: The Hybrid group demonstrated significantly improved intraoperative metrics. This cohort showed a highly significant decrease in blood loss (437.14 cc vs. 3,400 cc; p=0.018) and a significant reduction in surgical time (325 minutes vs. 530 minutes; p=0.018). Functionally, the Hybrid group achieved excellent recovery (median modified Rankin Scale [mRS] 1 at 6 months) despite having worse baseline morbidity (median mRS 3 vs. 1.5). The study found no significant difference in mRS improvement between groups.Conclusions: Preoperative embolization is associated with reduced blood loss and shorter surgical duration in cerebellar AVM resection. These findings support embolization as a valuable adjunctive therapy. The results provide strong preliminary evidence of efficacy and intraoperative safety, but validation in prospective studies with larger samples is required.<\/jats:p>","DOI":"10.7461\/jcen.2026.e2025.09.006","type":"journal-article","created":{"date-parts":[[2026,2,25]],"date-time":"2026-02-25T04:36:48Z","timestamp":1771994208000},"page":"235-246","update-policy":"https:\/\/doi.org\/10.7461\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Hybrid
