Traumatic intracranial pseudoaneurysms occurring after blunt head injuries are rare. We report an unusual case of subarachnoid hemorrhage (SAH) caused by rupturing of the traumatic pseudoaneurysm of the internal carotid artery (ICA) bifurcation that resulted from a non-penetrating injury. In a patient with severe headache and SAH in the right sylvian cistern, which developed within 7 days after...

Background: Subarachnoid hemorrhage (SAH) is associated with high morbidity and mortality. It is suggested that the associated inflammation is mediated through activation of the mitogen-activated protein kinase (MAPK) pathway which plays a crucial role in the pathogenesis of delayed cerebral ischemia after SAH. The aim of this study was first to investigate the timecourse of altered expression ...

Aneurysmal subarachnoid hemorrhage (SAH) is known as one of the most devastating diseases in the central nervous system. In the past few decades, research on SAH has focused on cerebral vasospasm to prevent post-SAH delayed cerebral ischemia (DCI) and to improve outcomes. However, increasing evidence has suggested that early brain injury (EBI) is an important mechanism contributing to DCI, cere...

Subarachnoid hemorrhage (SAH) causes widespread disruption in the cerebral architecture.The process of SAH is complicated and many people lose their lives or become disabled after injury. Mesenchymal stem cells (MSCs) are considered as good candidate for repair of cerebral damage. The aim was to assess the ultrastructural changes in the rat cerebral tissue after intravenous transplantation of M...

Based on media reports, neurotrauma has emerged as the signature wound in the Global War on Terrorism (GWOT). Brain trauma is frequently the result of blast injury, producing a unique syndrome with a high incidence of traumatic sub-arachnoid hemorrhage (SAH) and vasospasm. Cortical spreading depolarizations (CSD) are a pathologic short-circuiting of brain function that cause secondary brain dam...

BACKGROUND AND PURPOSE Subarachnoid hemorrhage (SAH) may appear on computerized tomography scans after mechanical thrombectomy for acute ischemic stroke. The incidence and prognosis of this observation remain unknown. We investigated the frequency and clinical consequences of SAH after treating acute ischemic stroke with a multimodal approach heavily weighted toward mechanical thrombectomy with...

Introduction: The occurrence of subarachnoid hemorrhage (SAH) in traumatic brain injury (TBI) is 12% ~ 53% and related to poor outcome (1, 2). Early diagnosis of SAH and active intervention in removing hemorrhage from subarachnoid space is of great significance in the management of acuteTBI. Susceptibility weighted imaging (SWI) has been successfully applied in TBI and proved to be 6 times more...
