PURPOSE OF REVIEW: This article reviews the epidemiology, clinical presentation, diagnosis, and management of patients with aneurysmal subarachnoid hemorrhage (SAH). SAH is a type of hemorrhagic stroke and is a neurologic emergency with substantial morbidity and mortality. This article reviews the most common and potentially life-threatening neurologic and medical complications to promote their early recognition and prevent secondary brain injury. RECENT FINDINGS: Over the past 30 years, the incidence of SAH has remained stable; yet, likely because of improved care in specialized neurocritical care units, discharge mortality has considerably decreased...

Hypertensive intracerebral hemorrhage (ICH) is a devastating cerebrovascular disease with no effective treatment. Lysyl hydroxylase 3 (LH3) is essential for collagen IV intermolecular crosslinking and stabilization. Deficiency in LH3 affects the assembly and secretion of collagen IV and basement membrane (BM) integrity of vessels. Here, we investigated whether LH3 has significant implications for disease progression and therapeutic intervention. Spontaneous hypertensive ICH of mice was induced by angiotensin II and L-NAME treatment...

A 32-year-old pregnant woman in her 39th week of pregnancy presented at the emergency room complaining of sudden-onset dizziness with gaze disturbance and was admitted to our hospital. Her past medical history included hypertension, diabetes mellitus and infarction in the right medulla oblongata 18 months prior to this event. Magnetic resonance (MR) angiography showed multiple irregular stenosis of the intracranial arterial system. Although MR images revealed no fresh ischemic or hemorrhagic lesions, she was diagnosed with reversible cerebral vasoconstriction syndrome (RVCS) associated with pregnancy...

Background and Purpose: Hypertensive vasculopathy and cerebral amyloid angiopathy are the two most common forms of cerebral small vessel disease. Both forms are associated with the development of primary intracerebral hemorrhage, but the pathophysiological mechanisms underlying spontaneous vessel rupture remain unknown. This work constitutes a systematic review on blood-brain barrier dysfunction in the etiology of spontaneous intracerebral hemorrhage due to cerebral small vessel disease. Methods: We searched Medline (1946-2018) and Embase (1974-2018) for animal and human studies reporting on blood-brain barrier dysfunction associated with intracerebral hemorrhage or cerebral microbleeds...

Pregnancy confers a substantially increased risk of stroke in women. The period of highest risk of stroke is the peripartum/postpartum phase, coinciding with the highest risk for hypertensive disorders of pregnancy and peak gestational hypercoagulability. Hemorrhagic stroke is the most common type of obstetric stroke. Hypertensive disorders of pregnancy are important contributors to obstetric stroke and predispose women to premature cardiovascular disease. The rate of stroke associated with hypertensive disorders of pregnancy has increased in the United States...

BACKGROUND: There is persistent uncertainty over the benefits of early intensive systolic blood pressure lowering in acute intracerebral hemorrhage. In particular, over the timing, target, and intensity of systolic blood pressure control for optimum balance of potential benefits (i.e. functional recovery) and risks (e.g. cerebral ischemia). AIMS: To determine associations of early systolic blood pressure lowering parameters and outcomes in patients with a hypertensive response in acute intracerebral hemorrhage...

PURPOSE OF REVIEW: Standard clinical protocols for treating cerebral edema and intracranial hypertension after severe TBI have remained remarkably similar over decades. Cerebral edema and intracranial hypertension are treated interchangeably when in fact intracranial pressure (ICP) is a proxy for cerebral edema but also other processes such as extent of mass lesions, hydrocephalus, or cerebral blood volume. A complex interplay of multiple molecular mechanisms results in cerebral edema after severe TBI, and these are not measured or targeted by current clinically available tools...

Dural arteriovenous fistula (dAVF) associated with an intracranial tumor is a relatively rare condition. Furthermore, to our knowledge, this is the first case report of dAVF associated with intratumor hemorrhage. We experienced this very rare case and report it here, along with a literature review. A 59-year-old woman presented with transient aphasia and dysgraphia. Computed tomography, magnetic resonance imaging, and angiography showed left anterior cranial fossa dAVF and a tumor with an intratumor hemorrhage...

BACKGROUND: Hypocapnia induces cerebral vasoconstriction leading to a decrease in cerebral blood flow, which might precipitate cerebral ischemia. Hypocapnia can be intentional to treat intracranial hypertension or unintentional due to a spontaneous hyperventilation (SHV). SHV is frequent after subarachnoid hemorrhage. However, it is understudied in patients with severe traumatic brain injury (TBI). The objective of this study was to describe the incidence and consequences on outcome of SHV after severe TBI...

Objective: Cerebral microbleeds (CMBs) are known as the neuroimaging markers of risk in stroke and dementia. Many studies on CMBs in elderly patients with hemorrhagic or ischemic stroke have been reported; however, reports on CMBs in young populations with intracerebral hemorrhage (ICH) are lacking. Materials and Methods: A total of 272 patients aged 18-54 years presented to our hospital with ICH between December 2009 and August 2017. Among these, CMB presence, count, and topography with respect to ICH were evaluated on magnetic resonance imaging (MRI) gradient echo images (GREs)...

Background and Purpose- Delayed cerebral ischemia (DCI) is an important cause of poor outcome after aneurysmal subarachnoid hemorrhage. If clinical signs of DCI occur, induced hypertension is a plausible but unproven therapeutic intervention. There is clinical equipoise if the use of hypertension induction is useful or not with the consequence that this strategy is irregularly used. We explored the effect of blood pressure augmentation in preventing cerebral infarction in patients with clinical signs of DCI...

BACKGROUND: De novo aneurysm formation after completely occluded aneurysms via clipping or coiling has not been well studied. Although known to occur several years after initial aneurysm management, the natural history of de novo aneurysms is obscure. We investigated the formation of new aneurysms in patients who had previously undergone treatment of intracranial aneurysms. METHODS: In a retrospective, single-institutional series, eligible patients who had undergone treatment of ruptured cerebral aneurysms from 2000 to 2011 were included...

Multifocal cerebral microhemorrhages (CMHs, also known as "cerebral microbleeds"), which are associated with rupture of small intracerebral vessels, have been recognized as an important cause for cognitive decline in older adults. Although recent studies demonstrate that CMHs are highly prevalent in patients 65 and older, many aspects of the pathogenesis and clinical significance of CMHs remain obscure. In this longitudinal observational study, a case of a 77-year-old man with multifocal CMHs is described, in whom the rupture of intracerebral vessels could be linked to repeatedly performing extended Valsalva maneuvers...
