The stroke rate, management, and outcome after blunt cerebrovascular occlusion (Biffl Grade IV injury) is not well defined, given the rarity of the disease. Both hemodynamic failure and embolic mechanisms have been implicated in the pathophysiology of subsequent stroke after blunt cerebrovascular occlusion. In this study, the authors evaluated their center's experience with Biffl Grade IV injuries, focusing on elucidating the mechanisms of stroke and their optimal management.A retrospective review identified all internal carotid artery (ICA) or vertebral artery (VA) Biffl Grade IV injuries over a 7-year period at a single institution.Fifty-nine Biffl Grade IV injuries were diagnosed affecting 11 ICAs, 44 unilateral VAs, and 2 bilateral VAs. The stroke rates were 64
