INTRODUCTION: The multiphase computed tomography angiography (mCTA) is superior to the noncontrast computed tomography (NCCT) in selecting patients that would benefit from mechanical thrombectomy following an acute ischemic stroke (AIS). It remains unclear whether the longer examination time of mCTA worsens outcomes of intravenous recombinant tissue plasminogen activator (IV r-tPA) or increases the risk of hemorrhagic transformation (HT) compared to NCCT in Asian stroke patients. METHODS: Between January 2011 and December 2017, 199 AIS patients receiving IV r-tPA with initial National Institute of Health Stroke Scale (NIHSS) scores between 6 and 25 were enrolled in a single medical center...

BACKGROUND: A cardiac origin in ischemic stroke is more frequent than previously assumed, but it is not clear which patients benefit from cardiac work-up if obvious cardiac pathology is absent. We hypothesized that thromboembolic stroke with a cardiac source occurs more frequently in the posterior circulation compared with thromboembolic stroke of another etiology. METHODS: We performed a multicenter observational study in 3,311 consecutive patients with ischemic stroke who were enrolled in an ongoing prospective stroke registry of 8 University hospitals between September 2009 and November 2014 in The Netherlands...

BACKGROUND: Emerging evidence indicates a beneficial effect of mesenchymal stem cell (MSC) transplantation in subarachnoid hemorrhage (SAH). Chronic hydrocephalus is a common complication after SAH, which is associated with subarachnoid fibrosis promoted by transforming growth factor-β1 (TGF-β1). This study investigated the effect of human umbilical cord derived MSCs (hUC-MSCs) with TGF-β1 knockdown on chronic hydrocephalus after SAH. METHODS: About 0.5 mL autologous blood was injected into the cerebellomedullaris cistern of 6-week SD rats to establish SAH model...

BACKGROUND: MicroRNAs (miRs) have a crucial regulatory role in endothelial cell function and tumor angiogenesis by inhibiting the expressions of their target genes. The participation of microRNA-384-5p (miR-384-5p) has been prominently reported in various ischemia-induced diseases such as myocardial ischemia and atherosclerosis. Hence, the present study aimed at exploring the effect of miR-384-5p on proliferation, apoptosis, and angiogenesis of endothelial progenitor cells (EPCs) in cerebral ischemic stroke and investigating the associated underlying mechanism...

The symptoms related to insular ischemia have been the object of several studies in patients affected by stroke, although they are often accompanied by other ischemic alteration of adjacent brain structures supplied by the middle cerebral artery (MCA). The insula is vulnerable because of an ischemia due to thromboembolic vascular occlusion of the M1 MCA segment and the 2 main MCA branches (M2), mainly when they abruptly arise from the principal stem at a right angle. This topographical and anatomical peculiarity could enable an embolic formation, especially due to atrial fibrillation (AF), to occlude the transition pathway between M1 and M2, while the proximal origin of vascular supply protects the insula from ischemia due to hemodynamic factors...

INTRODUCTION: Mechanical thrombectomy has become standard of care for emergent large vessel occlusive stroke. Estimates of incidence for thrombectomy eligibility vary significantly. National Institutes of Health Stroke Scale (NIHSS) of 10 or greater is highly predictive of large vessel occlusion. Using our Kentucky Appalachian Stroke Registry (KApSR), we evaluated temporal trends in stroke admissions with NIHSS ≥10 to determine patient characteristics among that group along with effects and needs in thrombectomy utilization...

BACKGROUND: Intracerebral hemorrhage is a devastating clinical event, and secondary prevention is pivotal to avoid further cerebral complications, but no clear guidance exist for selecting high-risk patients. The CHA2DS2-VASc score is a widespread tool to assess the risk of stroke among patients with atrial fibrillation (AF). OBJECTIVES: We investigated the ability of the CHA2DS2-VASc score for estimating cerebrovascular ischemic events in patients with recent intracerebral hemorrhage with or without comorbid AF...

BACKGROUND: Though obesity is a well-known risk factor for vascular disease, the impact of obesity on stroke outcome has been disputed. Several studies have shown that obesity is associated with better functional outcome after stroke. Whether obesity influences the benefit of endovascular treatment (EVT) in stroke patients is unknown. We evaluated the association between body mass index (BMI) and outcome in acute ischemic stroke patients with large vessel -occlusion (LVO), and assessed whether BMI affects the -benefit of EVT...

BACKGROUND: Circumferential enhancement along the aneurysm wall (CEAW) by magnetic resonance (MR) vessel wall imaging has been reported to be a useful indicator for the biological activity of intracranial aneurysms such as growth and rupture. However, the significance of CEAW in vertebral artery dissection (VAD) has not been examined in detail. We quantitatively analyzed CEAW on VAD focusing on the differences in the clinical onset type. METHODS: The subjects were 37 patients diagnosed with VAD who were evaluated by MR imaging in the acute phase of onset between January 2014 and May 2019...
