This book highlights the latest developments in acute and delayed neurovascular injury studies including delayed cerebral vasospasm, early brain injury, micro-circulation compromise, spreading cortical depolarization, neuroinflammation, and long-term cognitive dysfunctions after subarachnoid hemorrhage. About 32 chapters cover original presentations from the 14^th international conference on neurovascular events after subarachnoid hemorrhage, held in Los Angeles in October 2017. Neurosurgeons, neurologists, and neuro-ICU practitioners discuss clinical observations, new pilot treatments, clinical trials, academic and industrial interactions, including surgical and endovascular approaches, brain injury monitoring, new developments in brain imaging, ICU management, early brain injury scales and management, counter cortical depolarization management and anti-inflammation management. In addition, animal models used to study acute and delayed neurovascular events, the basic mechanisms of vascular, neuronal, and CSF physiology, new experimental treatment strategies, new frontiers in the treatment of neurovascular injuries, and new research directions are discussed.
