BACKGROUND AND PURPOSE: Arterial spin-labeling magnetic resonance imaging is sensitive for detecting hyperemic lesions (HLs) in patients with acute ischemic stroke. We evaluated whether HLs could predict blood-brain barrier (BBB) disruption and hemorrhagic transformation (HT) in acute ischemic stroke patients. METHODS: In a retrospective study, arterial spin-labeling was performed within 6 hours of symptom onset before revascularization treatment in 25 patients with anterior circulation large vessel occlusion on baseline magnetic resonance angiography...

INTRODUCTION: Chronic systematic inflammation has been suggested to be associated with the occurrence and development of cardiovascular events. Low-grade systematic inflammation persists in type 2 diabetes mellitus (T2DM) patients. In addition, the risk of cerebral hemorrhage in these patients is increased compared with non-diabetic patients. Neutrophil-to-lymphocyte ratio (NLR) is the ratio derived by dividing the neutrophil count with the lymphocyte count from a peripheral blood sample...

Ischemic stroke, intracerebral hemorrhage, subarachnoid hemorrhage, and traumatic brain injury-all have in common early brain injury due to brain tissue destruction, reduced cerebral blood flow and oxygen delivery, and overall substantial morbidity and mortality. The pathophysiology of brain tissue damage likely includes common cellular mechanisms. Neuroprotection has seldom, if ever, been shown to reduce early brain injury. Secondary brain injury develops after these conditions due to macroscopic events such as increased intracranial pressure and reduced cerebral blood flow, as well as cellular processes including vascular damage, inflammation, and apoptotic/necrotic cell death...

In recent decades, the medical and surgical treatment of intracerebral hemorrhage (ICH) have become the focus of a number of scientific investigations. This effort has been led by an international group of neurologists and neurosurgeons with the goal of studying functional recovery and developing new medical and surgical treatments to facilitate improved clinical outcomes. Currently, two of the most pressing ICH investigational goals are (1) early blood pressure control, and (2) safe hematoma volume reduction...

Neurosurgeons increasingly use decompressive craniectomy (DC) in neurocritical care. In this review, the authors summarize the topic of DC for the neurointensivist. Following a brief overview of the procedure, the major indications for the procedure are described. This includes a review of the literature regarding well-established indications, such as infarction and traumatic brain injury, as well as lesser known indications, including intracerebral hemorrhage, ruptured cerebrovascular malformations, sinus thrombosis, and infection...

PURPOSE OF REVIEW: An increasing number of patients are receiving oral anticoagulants. Since non-vitamin K antagonist oral anticoagulants (NOACs) were approved, primary prevention of ischemic stroke has become simpler. However, managing ischemic stroke and intracerebral hemorrhage while on oral anticoagulation (OAC) has become more complex. This review covers the latest developments in managing ischemic and hemorrhagic stroke in patients receiving vitamin K antagonists (VKA) and NOACs...

Therapeutic hypothermia (TH) is a potent neuroprotectant for experimental ischemic stroke, but studies of TH for intracerebral hemorrhage (ICH) are emerging. We systematically reviewed the experimental literature to assess TH efficacy for ICH. We found 18 suitable papers; quality scores were moderately good. Compared with normothermia, TH reduced measures of edema (mean effect size (95% CI) -1.6873 (-2.3640, -1.0106), p < 0.0001) or blood-brain barrier leakage (p < 0.0001) and improved behavioral outcomes (p < 0...

Quantitative susceptibility mapping (QSM) is an MR technique that depicts and quantifies magnetic susceptibility sources. Mapping iron, the dominant susceptibility source in the brain, has many important clinical applications. Herein, we review QSM applications in the diagnosis, medical management, and surgical treatment of disease. To assist in early disease diagnosis, QSM can identify elevated iron levels in the motor cortex of amyotrophic lateral sclerosis patients, in the substantia nigra of Parkinson's disease (PD) patients, in the globus pallidus, putamen, and caudate of Huntington's disease patients, and in the basal ganglia of Wilson's disease patients...

Studies treating intracerebral hemorrhage (ICH) with therapeutic hypothermia (TH) have shown inconsistent benefits. We hypothesized that TH's anti-inflammatory effects may be responsible as inflammatory cells are essential for removing degrading erythrocytes. Here, we subjected rats to a collagenase-induced striatal ICH followed by whole-body TH (∼33℃ for 11-72 h) or normothermia. We used X-ray fluorescence imaging to spatially quantify total and peri-hematoma iron three days post-injury. At three and seven days, we measured non-heme iron levels...

BACKGROUND AND PURPOSE: We assessed the elemental and biochemical effects of rehabilitation after intracerebral hemorrhage, with emphasis on iron-mediated oxidative stress, using a novel multimodal biospectroscopic imaging approach. METHODS: Collagenase-induced striatal hemorrhage was produced in rats that were randomized to enriched rehabilitation or control intervention starting on day 7. Animals were euthanized on day 14 or 21, a period of ongoing cell death...

BACKGROUND: Studies on antihypertensive treatment for surgical patients with spontaneous intracerebral hemorrhage are insufficient. This pilot study was conducted to investigate the safety of the perioperative intensive blood pressure lowering in surgical patients with spontaneous intracerebral hemorrhage. METHODS: This study was a prospective, parallel, randomized, assessor-blinded trial. Patients allocated to the intensive group received perioperative intensive antihypertensive treatment aiming to achieve a target systolic blood pressure between 120 and 140 mm Hg, whereas the patients in the conservative group received conservative treatment aiming to achieve a target systolic blood pressure between 140 and 180 mm Hg for 7 days...

BACKGROUND AND PURPOSE: Stroke is a risk factor for dementia, but the risk of dementia after different stroke types is poorly understood. We examined the long-term risk of dementia among survivors of any first-time stroke and of first-time ischemic stroke, intracerebral hemorrhage, and subarachnoid hemorrhage. METHODS: We conducted a 30-year nationwide population-based cohort study using data from Danish medical databases (1982-2013) covering all Danish hospitals...

PURPOSE: Intracerebral hemorrhage (IH) and cephalalgia are common consequences of traumatic brain injury. One of the primary obstacles for patient recovery is the paucity of treatments to support an appropriate analgesic protocol. The present study aimed to assess pain and motor behaviors following different doses of fentanyl on a rat model of IH. METHODS: Twenty-one male Sprague Dawley rats underwent a stereotaxic surgery to produce a collagenase-induced IH in the right caudoputamen nucleus...
