Intracranial Vessel Perforation During Mechanical Thrombectomy for Acute Ischemic Stroke: Incidence, Management, and Outcomes - A Systematic Review and Meta-Analysis.

Medium-vessel occlusion thrombectomy showed a higher observed incidence than large-vessel occlusion thrombectomy (3.68% vs 1.52%), but this comparison was based on three medium-vessel cohorts with substantial heterogeneity and should be interpreted as hypothesis-generating.

Five hemostatic strategy categories were identified; in one study, successful reperfusion was associated with functional independence in 60% versus 12.5% (p=0.006).
