BACKGROUND AND PURPOSE: Patients presenting with an intracerebral hemorrhage (ICH) generally have an initial noncontrast computed tomography (NCCT) of the brain. Computed tomography angiography (CTA) can help identify secondary causes of ICH and detect a "spot sign." We hypothesized that performing an urgent CTA in the setting of a presumed primary ICH has only limited utility and did not alter urgent management. METHODS: This was a retrospective study of consecutive patients presenting with a primary ICH identified from the Duke University Stroke Registry from 2010 to 2013 who had an ICH detected on an initial NCCT...

Matrix metalloproteinases are versatile endopeptidases with many different functions in the body in health and disease. In the brain, matrix metalloproteinases are critical for tissue formation, neuronal network remodeling, and blood-brain barrier integrity. Many reviews have been published on matrix metalloproteinases before, most of which focus on the two best studied matrix metalloproteinases, the gelatinases MMP-2 and MMP-9, and their role in one or two diseases. In this review, we provide a broad overview of the role various matrix metalloproteinases play in brain disorders...

After performing a decompressive craniectomy, a cranioplastic surgery is usually warranted. The complications of this reconstructive procedure may differ from the initial operation. The authors of this study report on their experience to define patient-specific and procedural risk factors for possible complications following cranioplasty influencing the outcome (Glasgow Outcome Scale (GOS)), mobility, shunt dependency, and seizures. A retrospective analysis of 263 patients of all ages and both sexes who had undergone cranioplasty after craniectomy for traumatic brain injury (including chronic subdural hematoma), subarachnoidal hemorrhage (including intracerebral hemorrhage), ischemic stroke, and tumor surgery in one single center in 12 years from January 2000 to March 2012 has been carried out...

INTRODUCTION: Intravenous administration of tissue-type plasminogen activator (IV-tPA) remains the only approved therapy that may reverse neurological deficit in patients with acute ischemic stroke (AIS). During the past 20 years, accumulating real-word experience have provided additional information regarding its safety and efficacy in various clinical settings that were originally considered as contraindications for systemic thrombolysis. AREAS COVERED: In this narrative review, we address the safety of intravenous thrombolysis (IVT) in specific conditions: dissection of the aortic arch of extracranial and intracranial arteries, concomitant presence of unruptured intracranial aneurysms, arteriovenous malformations and dural fistulas, co-existing brain tumors as well as in conditions mimicking AIS...

A 48-year-old woman with no previous neurological diseases was transferred to our hospital because of sudden-onset unconsciousness. On arrival, she showed consciousness disturbance (E1V1M3 on the Glasgow Coma Scale), tetraplegia, right conjugate deviation and bilateral pathological reflexes. These symptoms resulted in a NIH stroke scale score of 32. Brain diffusion-weighted MR imaging (DWI) showed multiple hyper-intense lesions, and MR angiography revealed occlusions of the basilar artery (BA) and superior branch of the right middle cerebral artery (MCA)...

Seizures are a well-described complication of acute brain injury and neurosurgery. Antiepileptic drugs (AEDs) are frequently utilized for seizure prophylaxis in neurocritical care patients. In this review, the Neurocritical Care Society Pharmacy Section describes the evidence associated with the use of AEDs for seizure prophylaxis in patients with intracerebral tumors, traumatic brain injury, aneurysmal subarachnoid hemorrhage, craniotomy, ischemic stroke, and intracerebral hemorrhage. Clear evidence indicates that the short-term use of AEDs for seizure prophylaxis in patients with traumatic brain injury and aneurysmal subarachnoid hemorrhage may be beneficial; however, evidence to support the use of AEDs in other disease states is less clear...

OBJECT: Currently, perfusion CT (PCT) is a valuable imaging technique that has been successfully applied to the clinical management of patients with ischemic stroke and aneurysmal subarachnoid hemorrhage (SAH). However, recent literature and the authors' experience have shown that PCT has many more important clinical applications in a variety of neurosurgical conditions. Therefore, the authors share their experiences of its application in various diseases of the cerebrovascular, neurotraumatology, and neurooncology fields and review the pertinent literature regarding expanding PCT applications for neurosurgical conditions, including pitfalls and future developments...

BACKGROUND: Cerebral microdialysis (MD) provides valuable information about brain metabolism under normal and pathologic conditions. The CMA 600 microdialysis analyzer received US Food and Drug Administration (FDA) approval for clinical use in the United States in 2005. Since then, cerebral MD has been increasingly utilized nationally in the multimodal monitoring of traumatic brain injury (TBI), stroke, aneurysmal subarachnoid hemorrhage, and brain tumors. We describe a 5-year, single-institutional experience using cerebral MD at a community-based hospital, Legacy Emanuel Medical Center (LEMC)...

BACKGROUND: Cardiac myxomas are rare but are the most common cardiac tumors. This study is based on our clinical experience with cardiac myxomas over a period of 11 years at Sejong General Hospital. We focused on the embolic complications of patients with cardiac myxoma. METHODS: We retrospectively reviewed the medical records of 59 consecutive patients with cardiac myxoma who were treated between January 2000 and March 2011. The myxomas were divided into two types: type 1, with an irregular or villous surface and a soft consistency, and type 2, with a smooth surface and a compact consistency...

INTRODUCTION: Ischemic stroke is the leading cause of mortality in Portugal, with around 30 to 50 % of cases being of cardioembolic etiology. Transesophageal echocardiography (TEE) has assumed growing importance in the detection of cardiac sources of embolism. However, there is controversy regarding the implications of TEE findings for the therapeutic approach to patients with ischemic stroke. OBJECTIVES: To analyze TEE findings in the diagnostic work-up of patients with ischemic cerebral events and to determine their influence on therapeutic strategy...

Shortly after the first extracranial to intracranial (EC-IC) carotid artery bypass was performed by Yasargil in 1967 for internal carotid artery occlusion, cerebral revascularization became widely accepted in the neurosurgical field, and the procedures became increasingly used as practitioners began to master the technical aspects of the surgery. The procedures were performed for intracranial arterial stenosis and occlusion and used as an adjunct in the treatment of large aneurysms and skull base tumors. The results of the EC-IC bypass group trial in 1985 were surprising to many and sobering to all; EC-IC bypass for stenosis or occlusion of the high internal carotid artery or middle cerebral artery did not decrease the risk of subsequent stroke compared with medical management...

Moyamoya is a cerebrovascular angiopathy characterized by a progressive stenosis of the terminal part of the intracranial carotid arteries and the compensatory development of abnormal and fragile collateral vessels, also called moyamoya vessels, leading to ischemic and hemorrhagic stroke. Moyamoya angiopathy can either be the sole manifestation of the disease (moyamoya disease) or be associated with various conditions, including neurofibromatosis, Down syndrome, TAAD (autosomal-dominant thoracic aortic aneurysm), and radiotherapy of head tumors (moyamoya syndromes)...

INTRODUCTION: Myxoma is a rare benign primary cardiac tumor. It may cause vascular complications. Neurological symptoms may precede or accompany the diagnosis of myxoma with systemic embolization occurring most often in the cerebral circulation. OBSERVATION: We report a case of cardiac myxoma complicated with cerebral aneurysms and revealed by an ischemic stroke in a 21-year-old patient. The cardiac myxoma was discovered during the transthoracic echocardiography performed as part of the etiological work-up...

BACKGROUND: Intracerebral hemorrhage (ICH) is associated with the highest mortality of all strokes. Admission to a Neurosciences Critical Care Unit (NCCU) compared to a general ICU has been associated with reduced mortality following ICH. Such association has led to several hospitals transferring ICH patients to Neuro-ICUs in tertiary care centers. However, delays in optimizing ICH management prior to and during transfer can lead to deleterious consequences. To compare functional outcomes in ICH patients admitted to our NCCU directly from the ED versus inter-hospital transfer admissions...

BACKGROUND: Curative therapy for childhood cancer has dramatically improved over past decades. Therapeutic radiation has been instrumental in this success. Unfortunately, irradiation is associated with untoward effects, including stroke and other cerebrovascular disease (CVD). The Children's Oncology Group (COG) has developed guidelines for screening survivors at risk for persistent or late sequelae of cancer therapy. OBJECTIVES: This review summarizes the pathophysiology and relevant manifestations of radiation-induced CVD and outlines the specific patient groups at risk for early-onset stroke...
